In the unlikely event that the system needs to be returned to the JSI Factory, the packaging will help prevent shipping damage and maintain warranty. Each EDI-120 retrofit control system includes all of the parts required to complete the retrofit. Parts included with the EDI-120 retrofit control system: 10 (3m) Belden 9829 (or equivalent) length of cable used to extend existing DMX cable(s). Two (2) 3-position breakaway connectors used to splice the existing DMX cable(s) to the supplied DMX cable. Typical installations already contain the control wiring within the OEM P1 connector wiring, and these wires are not required. 10 (3m) yellow CAT 5e patch cable used to daisy-chain the DMX-A and DMX-B between multiple EDI-120 retrofit control systems. Only supplied when multiple EDI-120 retrofit control systems are purchased. Dimensional Drawings NOTE: All measurements are in inches. 4 5 Installation Disconnect (turn off) the power supply to the EDI Mark VII dimmer rack(s). WARNING! Verify all power is disconnected (turned off) before proceeding. Removal of the old EDI Control Module Remove the four (4) mounting screws securing the EDI Mark VII control module. Carefully pull the control module forward until all of the rear wiring connections are visible. Do not disconnect any wiring at this point. If you are not familiar with the EDI Mark VII control module electronics and wiring, it is strongly advised that you take a few minutes to inspect the OEM (Original Equipment Manufacturer) wiring (P1 through P6). If the cables aren t already labeled, label them using a permanent marker (Sharpie). P1 contains the AC power supply conductors (Neutral, Phase A, Phase B and Phase C) used to power the control module, as well as the low voltage fan control wiring (positive DC voltage control and common). Observe the location of the P1 connector and compare it to the location of the P1 connector on the EDI-120 retrofit.http://www.seaessential.it/public/cyber-shot-dsc-s750-manual.xml If the P1 connector is located on the opposite side, refer to the installation of the new EDI-120 retrofit system for details. On some earlier versions of EDI Mark VII dimmer racks, the fan control was sensed from the house control inputs, and the fan control wiring does not come through the P1 connector. If this is the case, the fan control will need to be rewired from the P1 connector to the fan SSR. More information regarding this modification is provided in the Installation of the new EDI-120 retrofit system section of this manual. P2 contains the field wiring connections for DMX and analog control. NOTE: The P2 connection is obsolete when the EDI-120 retrofit control module is installed, and all the field wiring must be terminated on the back of the EDI-120 retrofit control module. Refer to the installation of the new EDI-120 retrofit system for more details. P3 contains the PWM output control signals for dimmers 1 through 36. P4 contains the PWM output control signals for dimmers 25 through 60. P5 contains the PWM output control signals for dimmers 61 through 96. P6 contains the PWM output control signals for dimmers 85 through 120. All of the internal OEM wiring must remain intact to complete the retrofit. Compare these connections to the ones on the back of the EDI-120 retrofit control module. Do not disconnect any wiring until you are completely satisfied with how easy this is going to be. Carefully squeeze the latches on each side of the connector together to release the connector and then pull the connector out. Inspect the connector and the termination of the wires in the connector. Be sure everything looks okay. This cable will not be re-used on the EDI-120 retrofit, so once the old control module is removed, it should be coiled up, wire-tied and carefully set aside inside the dimmer rack, making sure it is isolated from any AC line voltage. Again, be sure not to pull directly on the ribbon cable to remove the connector as this may cause damage.http://fscl.ru/content/boss-br-1180-manual-espa-ol Carefully pull the connectors straight out. The old control module should now be free and clear of all connections, and can now be completely pulled out of the dimmer rack and set aside. With the old control module removed, it is a great opportunity to do some preventative maintenance. The dimmer rack should be thoroughly cleaned, vacuumed and sprayed out using compressed air. All of the AC line and load connections should be inspected and tightened if necessary. Inspect the fan blower and be sure it spins freely. If required, replacement fans are available. Installation of the new EDI-120 Retrofit Control System Remove your new EDI-120 retrofit control system from the box. Take a look at the field wiring connections on the back of the EDI-120 retrofit. All of the field wiring terminates on these connectors. On the old EDI control module (Multi-Link), the DMX input came through the P2 connector. Once the cable(s) has been located, disconnect it. Inspect the cable(s) and ensure it will be long enough to reach the connectors on the EDI-120 retrofit, once it is installed. Two (2) 3-position breakaway connectors and a 10 (3m) Belden 9829 (or equivalent) length of cable is supplied for extending the cable(s) if it isn t long enough. The cable(s) can now be dressed out and terminated on the DMX-A input and DMX-A thru (if applicable) breakaway connectors provided. Be sure to isolate and protect all shield wires and comply with standard RS-485 termination practices. On the old EDI control module, the 0-10VDC analog inputs came through the P2 connector. Note the EDI-120 retrofit only has four (4) 0-10VDC analog inputs, versus ten (10) on the old control module. Once the analog input cable(s) have been located, disconnect them. If required, extend the cables. The cable(s) can now be dressed out and terminated on the analog input breakaway connector provided. 6 7 If more than four (4) analog inputs are required, additional equipment may be necessary to facilitate them.http://apartmangyula.com/images/carrier-vvt-system-design-manual.pdf Consult the factory for options and further information. The intention is for the DMX input receptacle (5-pin male XLR) on the front of the EDI dimmer rack to be connected to the DMX-B input on the EDI-120 retrofit. To do this, the existing wires connected to the XLR must be disconnected, and an applicable length of the supplied 10 (3m) Belden 9829 (or equivalent) cable must be reconnected to the XLR on one end, and terminated on the DMX-B input breakaway connector provided on the other end. Alternatively, the DMX-B input and thru connectors can be used for other purposes. Confirm all applicable field wiring is terminated on the breakaway connectors provided. For future reference, be sure all cables are labeled using a permanent marker (Sharpie). Inspect the OEM P3, P4, P5 and P6 ribbon cables and determine if they are long enough to easily connect to the EDI-120 retrofit. Four (4) 1 (30.5cm) extension ribbon cables have been provided to extend the OEM ribbon cables for ease of installation. One end of the ground wire has a female disconnect, and connects to the male on the back of the EDI-120 retrofit. Locate a place inside the dimmer rack chassis to connect the other end of the ground wire. Cut the wire to length, dress it out and connect (fasten) it to the dimmer rack chassis. WARNING: Ensure chassis is connected to earth ground. For the brown (fan control V- (common)) wire, the female pin on the one end inserts into pin 6 of the P1 connector and the other end terminates to V- (common) on the fan SSR. Refer to page 10 for the P1 power connector pinout information. When looking at the EDI-120 from the rear view, the P1 connector is installed on the left-hand side location (more common) by the factory. Have a look at which side the power cable comes out in the dimmer rack and determine if the P1 connector needs to be moved to the right-hand side location. 7 8 Ensure chassis is connected to earth ground. Remove the lid and set it aside, along with the screws. Set the cover plate aside, along with the screws. Release the P1 power connector by carefully squeezing the tabs on each side of the connector together and pushing the connector back. Cut and remove the wire-tie securing the cable to the EDI-120 chassis via the bridge lance located on the front-side of the chassis. Neatly route the cable and then clip the P1 connector into place. Be sure the P1 connector is fully seated and secure. Use a wire-tie to secure the cable to the chassis there is a bridge lance located above the power supply on the front-side of the chassis. Reinstall the cover plate over the P1 connector opening on the left-hand side of the chassis. Reinstall the lid. A 10 (3m) yellow CAT 5e patch cable is supplied to daisy-chain the DMX-A and DMX-B between multiple EDI-120 retrofit systems, in multirack installations and racks containing more than 120 dimmer circuits. If applicable, route the cable into place. Everything should now we prepared and ready for final installation of the EDI-120 retrofit. Put the EDI-120 retrofit into a position where all the field wiring and OEM wiring can be plugged in. Connect (plug in) in the green ground wire onto the EDI-120 chassis connector. If applicable, connect (plug in) in the yellow CAT 5e patch cable. Connect (plug in) the prepared DMX input and thru connectors. Connect (plug in) the prepared analog input connector. Connect (plug in) the OEM P1 power connector. Connect (plug in) the OEM P3, P4, P5 and P6 ribbon cable connectors. All of the field wiring and OEM cables should now be connected (plugged in). Be sure all connections are secure and fully seated. Slide the EDI-120 retrofit along the guide rails and into place. Be sure not to pinch any of the cables. On some earlier versions of EDI Mark VII dimmer racks, the guide rail opening for the EDI-120 retrofit may be much narrower. If this is the case, the guide rails will need to be removed. Once the guide rails are removed, the EDI-120 retrofit will need to held in place and secured using the mounting screws provided. Verify the operation of the system status LED indicators, LCD display and programming switches. Refer to the programming section of this manual for system configuration. Test the system thoroughly to ensure all wiring terminations are functioning. Verify all of the dimmer control outputs have the correct phase referencing. If a dimmer control output is patched to the incorrect phase reference, the dimmer will not dim correctly and will go to full output at around 1 DMX input. The factory configuration for EDI-120 retrofit systems is for 3-phase applications, with the dimmer phase reference patch set at AABBCCAABBCC. Verify the fan blower is operating properly. Torque connections to 3.5 IN-LBS (0.4 NM). NOTE: For connection use copper wire only, rated for 167 F (75 C) minimum. For multi-rack EDI-120 installations, a 10 (3m) CAT 5e patch cable is supplied. This cable is used to daisychain the DMX-A and DMX-B between systems. The CAT 5e patch cable plugs into the RJ45 connectors located at the rear of the EDI-120 chassis. Complies with USITT DMX512-A (ANSI E ), standard protocol for digital data control. Recommended cable is Belden 9829, 9842, Cat 5 or equivalent (low-capacitance, twisted pair). Wiring must follow a daisy-chain topology. Maximum of 32 receiving devices on a single DMX line. Maximum cable length is 1,500 feet (455 meters). For more information, Google DMX, or visit: NOTE: Ensure only the last (end-of-line) DMX receiving device is terminated. Refer to menu items DMXA TRM and DMXB TRM on page 21 for further details. External devices should not exceed the maximum combined current draw of 2 Amps. 0-10VDC Analog Inputs or Load Shed Contact Inputs Four (4) analog inputs terminate on the 6-position breakaway connector provided. Inputs can be configured for normal or load shed mode of operation. Inputs can be patched to any combination of dimmer control outputs. Programmed in the ANA MODE and ANA PAT menus. See page 25 for details. Over-Temperature Input (Normally Open) OVERTEMP INPUT (N.O.) is terminated on the 6-position breakaway connector provided. Fire Alarm Input (Normally Open) FIRE ALARM (N.O.) is terminated on the 6-position breakaway connector provided. Programmed in the F-ALARM menu. See page 27 for details. Security Alarm Input (Normally Open) SECURITY ALARM (N.O.) is terminated on the 6-position breakaway connector provided. Programmed in the S-ALARM menu. Auxiliary Input (Normally Open) AUXIALIARY INPUT (N.O.) is terminated on the 6-position breakaway connector provided. Programmed in the AUX IN menu. See page 26 for details. Open Collector Output OPEN COLLECTOR OUTPUT is terminated on the 6-position breakaway connector provided. Sink up to 100mA. Trigger Solid State Relays (SSR) or other external devices. See page 26 for details. 12 13 EEPROM Memory Module EEPROM Memory Module All EDI-120 retrofit control systems come equipped with a removable EEPROM memory module located at the rear of the EDI-120 chassis. The EEPROM memory module inserts into the on-board connector located at the rear of the EDI-120 chassis. The EEPROM memory module is primarily used to backup important configuration settings, and may be removed for safe storage. If a firmware update is required, Johnson Systems Inc.The firmware EEPROM memory module can be inserted into connector, and the firmware can be loaded into the microcontroller. Refer to menu items EEPROM, FW-LOAD, RESTORE and BACKUP on page 29 to 31 for further details. NOTE: Be sure to BACKUP the EDI-120 when installation configuration is complete. 13 14 User Interface Infrared LED LCD Display System Status LED Indicators Programming Switches EDI-120 retrofit control systems are equipped with a user interface. The user interface provides access to all programming and configuration settings. System status is easily visible on the LCD display and LED indicators. An infrared LED allows for printout of all system configuration settings when used with a hand held infrared printer (Johnson System Inc., Part Number: JS-IP). All of the programming is accomplished using four (4) switches. Within a few minutes most users will find the menu structure very intuitive and easy to navigate. All configuration settings are automatically stored in the on-board EEPROM. LCD Display The LCD display is capable of displaying 2 lines of 8 Characters. A backlight automatically comes on when activity is sensed on the switches. The LCD contrast can be easily adjusted for optimum viewing. Refer to menu item LCD VIEW on page 32 for further details. Pressing and holding either switch will speed up the scroll rate, which can be helpful to speed up the configuration time. The ESCAPE ( ) switch is normally used to back up within a selected menu item one step at a time or exit the menu completely. NOTE: The programming switches can be locked out to prevent inadvertent configuration changes. To toggle between LOCKED!! and UNLOCKED press and hold down the EXECUTE and then ESCAPE switches at the same time for 4-5 seconds. The RESET switch has two purposes. First, it allows for quick exit from a menu item after a programming change and automatically puts the system into normal run mode. Second, it provides a soft reboot for the systems microcontroller. NOTE: A detailed procedure for programming all system configuration menu items can be found on page 18 to 15 System Status LED Indicators RUN (Green) Illuminates when the power is on and the microcontroller status is in normal run mode. The LED will flash slowly (once per second) when an under-voltage state of less than 100 VAC is sensed and will flash quickly (twice per second) when an over-voltage of greater than 130 VAC is sensed. DMX A and DMX B (Yellow) Illuminates when valid DMX is received on each of the inputs. Flashes when invalid DMX is received. ALARM Illuminates and flashes twice per second when either a fire or security alarm is sensed on each of the inputs. When DMX is not being received, the top line of the LCD display shows EDI-120, unless the system is in standby mode, then STANDBY.Below are descriptions for each status indication. NO RX! Displayed when DMX is not being received on either input and the system is not in scene mode. AXXXBXXX Displayed when valid DMX is being received on one or both inputs and both inputs are not terminated. A and B represent the DMX A and DMX B inputs while XXX represents the number of channels being received in each packet of data. For example, if the system is receiving 512 channels on DMX B and DMX A is disconnected, the display will show A000B512. XXX XXX Same as above except the A and B is replaced with to indicate if one or both of the DMX inputs are terminated. For example, if the system is receiving 48 channels on DMX A and 512 channels on DMX B, with only DMX A terminated, the display will show 048B512. SH XX:YY Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time is counting down. XX represents minutes while YY represents seconds. Refer to menu item SH TIME on page 23 for further details. 15 16 INF HOLD Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time is set for infinite (INF) hold. Refer to menu item SH TIME on page 23 for further details. SCENE:XX Displays the scene (1 to 12) that is currently activated. The colon in front of the scene number flashed twice per second during fading. Refer to menu item SCENEMOD on page 27 for further details. A-SCENE! Displayed when the auxiliary input is triggered. Refer to menu item AUX IN on page 26 for further details. FIRE!!! Displayed when the fire alarm input is triggered. Refer to menu item F-ALARM on page 27 for further details. SECURITY Displayed when the security alarm input is triggered. Refer to menu item S-ALARM on page 27 for further details. DIM-TEMP Displayed when an external dimmer over-temperature is sensed via a dimmer module. All dimmer outputs are disabled until the dimmer module temperature drops to within specification. EXT-TEMP Displayed when an external over-temperature is sensed via the over-temperature input. All dimmer outputs are disabled and the fans are turned on to full until the external devices temperature drops to within specification. See Over-Temperature Input information on page 12 for further details. CTL-TEMP Displayed when the microcontroller senses an internal over-temperature condition of 185 F (85 C) or more. All dimmer outputs are disabled and the fans are turned on to full until the temperature cools down to 178 F (81 C) or less. A phase error can be caused from an under-voltage of less than 100VAC, an over-voltage of greater than 130VAC, or if a zero-cross phase reference is not detected. RTC ERR! Displayed when the system detects a runtime counter (RTC) error. This occurs when there is an invalid hard-key code and the runtime counter is greater than 2160 hours (90 days). Refer to menu item HARD-KEY on page 29 for further details. LOCKED!! Displayed when an attempt is made to access the system configuration menu items and the programming switches are locked out. The sequence of the following system configuration menu items appear as the MENU DOWN ( ) switch is pressed. Pressing the MENU UP ( ) switch will sequence the system configuration menu items in the opposite order. When scene mode is activated the selected scene will be held with no timeout until the menu is exited. The 120 control channel levels are configured within the menu and can be modified on the fly. Scene mode is useful when an external controller is not available and independent internal control is required. Press EXECUTE to enter the menu and activate scene mode. CTRL: ON Control (CTRL) is ON via the selected scene. CTRL:DMX Control (CTRL) is via DMX and takes priority over scene mode. CTRL:HLD Control (CTRL) is via DMX status hold (HLD) and takes priority over scene mode. SCENE:12 The colon (:) flashes twice per second while fading to the selected scene. SCENE:12 The colon (:) stops flashing when fade is complete and the selected scene is active. SCENE 12 Press EXECUTE to modify the selected scene. C001 L00 The second line on the LCD indicates the control channel (C) and level (L). C120 L00 Press MENU ( ) to select the control channel (C) to modify from 01 to 120. C120 L00 Press EXECUTE to toggle from channel (C) to level (L) selection. C120 L00 Press ESCAPE to toggle from level (L) to channel (C) selection.

Press EXECUTE if you are sure to clear the selected preset. DONE!!! Indicates the selected preset has been cleared. WAIT. Press ESCAPE to exit and the menu and save programmed scene levels. Press RESET to exit scene mode without saving programmed scene levels. NOTE: When scene mode is activated: DMX and DMX status hold (SH TIME) automatically takes precedence over scene mode. The analog input levels are merged (HTP) with the scene levels. If the analog inputs are configured for load shed mode the inputs will take precedence over the active scene. The security alarm (S-ALARM) input is merged (HTP) with the scene levels while the fire alarm (F-ALARM) input automatically takes precedence. Scene mode (SCENEMOD) and the auxiliary input (AUX IN) are temporarily enabled. Scene mode will only activate dimmers assigned to room A. 18 19 2. FADETIME Set the fade time for each of the 12 scenes from 0 to 99 seconds. The factory default is 5 seconds for all 12 presets. Press EXECUTE to enter the menu. Press ESCAPE to exit the menu and save the selected fade time. Press RESET to exit the menu without saving. The menu will automatically timeout after 5 minutes of inactivity and save. 3. SNAPSHOT Record DMX levels into the backup scenes. Provides a quick and easy way to save control channel levels into each of the 01 to 12 backup scenes using a DMX source. Press EXECUTE to enter the menu and activate snapshot mode. SURE??? Press EXECUTE if you are sure the DMX levels are set as intended. DONE!!! DMX levels have now been saved in the selected scene. NO RX! DMX is not being received on either input, so a snapshot is not possible. A technician s best friend. Used for troubleshooting the dimmer outputs and field wiring to the load. Press EXECUTE to enter the menu and activate dimmer test mode. D001 L00 Displays the active dimmer (D) and the test level (L). D120 L00 Press MENU ( ) to select the dimmer (D) to test from 001 to 120. DALL L00 Press MENU ( ) to select and test all (ALL) the dimmers at once. D001 L00 Press EXECUTE to toggle between dimmer (D) and level (L) selection. D001 LFL Press MENU ( ) to select the desired test level from 00 to 100 (FL). D001 LFL Press ESCAPE to toggle the test level between full-on (FL) and off (00). Press ESCAPE or RESET to exit the menu. The menu will automatically timeout after 5 minutes of inactivity. 5. MONITOR View the control level to each dimmer output. The dimmer control level is displayed as a 9-bit value from 000 to 512. This menu does not timeout automatically and will continue to monitor indefinitely. Press EXECUTE to enter the menu and activate monitor mode. D001L000 Press MENU ( ) to select the dimmer (D) output to monitor from 001 to 120. D120L512 Display shows dimmer 120 has full-on (512) control. NOTE: The control level value will not reach 512 when voltage output limiting is activated, or when regulation is enabled and the line voltage is greater than 118 VAC. 19 20 6. ADDRESS Set the DMX start address. The DMX start address can be assigned from 001 to 512 and is common to both DMX inputs. The DMX inputs are merged and DMX-B is offset by the number of DMX-A channels. Press ESCAPE to exit the menu and save the selected DMX start address. The menu will automatically timeout after 5 minutes of inactivity and save. There are five different mode settings for the DMX protocol manager. Priority A (PTY A) and Priority B (PTY Dirol modes are intended for the implementation of a backup DMX source. Priority A (PTY A) sets the DMX A input as the priority, and ignores the DMX B input when the DMX A input is active. Priority B (PTY Dirol sets the DMX B input as the priority, and ignores the DMX A input when the DMX B input is active. Merge (MERGE) mode combines both DMX inputs with highest-takes-precedence (HTP) operation. Merge mode allows for simultaneous DMX control of the dimmers from both inputs, and is the default for the system. It permits two independent DMX sources to be active on the DMX inputs, with each having a separate DMX start address. The DMX inputs are merged and DMX-B is offset by the number of DMX-A channels programmed via the ADDRESS menu (see ADDRESS - above for further details). This feature is typically used when a system is at the end of one DMX universe (DMX-A) and the beginning of another (DMX-B). Two Room (2 ROOM) mode enables the room (A or Dirol assignment for each of the dimmer outputs via the 2 RM SET menu. PTY A Press EXECUTE to toggle into Priority A (PTY A) mode. PTY B Press EXECUTE to toggle into Priority B (PTY Dirol mode. MERGE Press EXECUTE to toggle into Merge (MERGE) mode. Any change in the configuration is automatically saved. This menu is used to assign each of the 120 dimmer outputs to room A or room B. Dimmer outputs assigned to room A are controlled via the DMX-A input. Dimmer outputs assigned to room B are controlled via the DMX-B input. This creates separation within the dimmer rack and makes a single dimmer rack function as though it is two independent dimmer racks. When used in conjunction with the DC PATCH menu, the dimmer rack can be configured for sequential DMX control of two rooms, even if the dimmer room assignments are not sequential. DMX MODE must be set for 2 ROOM operation for this menu to function. Press EXECUTE to enter the menu and activate 2 RM SET mode. D 001 A Displays the dimmer (DIM) output (01) and the room assignment (A). D 120 A Press MENU ( ) to select a different dimmer output from 01 to 120. D 120 B Press EXECUTE to toggle the room assignment from A to B. Press ESCAPE or RESET to exit the menu. DMX termination is indicated on the LCD display when DMX is being received. When the DMX A input is not terminated (DISABLED) the LCD display will read AXXXBXXX. When the DMX A input is terminated (ENABLED) the LCD display will read XXXBXXX. ENABLED Press EXECUTE to toggle termination from ENABLED to DISABLED. DISABLED Press EXECUTE to toggle termination from DISABLED to ENABLED. NOTE: Ensure only the last (end-of-line) DMX receiving device is terminated! 10. DMXB TRM Enable or disable termination on the DMX B input. When the DMX B input is not terminated (DISABLED) the LCD display will read AXXXBXXX. When the DMX B input is terminated (ENABLED) the LCD display will read AXXX XXX. OFFSET mode is typically used for the majority of systems, and is the factory default. OFFSET mode refers to the DMX start address, with each of the 120 dimmer (PWM) outputs addressed sequentially from the DMX start address. PATCH mode provides full flexibility for addressing each of the 120 dimmer (PWM) outputs. Each of the 120 dimmer (PWM) outputs can be patched to (controlled from) any DMX input channel from 001 to 512, from either or both of the DMX A and DMX B inputs simultaneously. With DMX patch mode activated, any configuration within the ADDRESS, DMX MODE, 2 RM SET and DC PATCH menus is ignored, and the DMX patch configured within the DMXA PAT and DMXB PAT menus takes precedence.
