E 1-1 Section E 1 WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. 1. Introduction The input/output (I/O) board for Series 3000V hot melt units allows you to connect devices to the unit to remotely monitor and control key unit features. The I/O board is available in two versions: standard and enhanced. The standard I/O board inputs allow you to remotely turn the standby feature on remotely turn the heaters on have the unit automatically enter the standby mode if guns are not fired for a specified period of time The standard I/O board outputs allow you to remotely monitor power on/off status pump on/off status standby on/off status warning conditions In addition to providing the same inputs and outputs as the standard I/O board, the enhanced I/O board has additional inputs that allow you to remotely disable hoses and guns.
E 1-2 1. Introduction (contd.) See Figure E 1-1. The I/O board has two terminal blocks where you connect the I/O wiring. On the standard I/O board, the terminal blocks are labeled TB10 and TB20. On the enhanced I/O board, they are labeled X1 and X2. 1 2 3 2 A 4 5 Fig. E 1-1 Standard I/O Board (A) and Enhanced I/O Board (B) 1. TB10 terminal block 4. X2 terminal block 2.

E 1-3 2. Input/Output Connections If you purchased the I/O board option for your unit, the I/O board is already installed. You will need only to install ferrites and connect the I/O wiring. A ferrite is a device used to reduce electrical noise. WARNING: Risk of equipment damage, personal injury, or death. Disconnect and lock out electrical power to the unit, including input/output (I/O) lines. 1. Turn off the unit; then disconnect and lock out electrical power to the unit. 2. Open the electrical enclosure. Refer to Opening and Closing the Electrical Enclosure in the Control section. 3. If you have not already done so, carefully remove a plug from one of the smaller knockout holes on either the back side or the bottom of the unit (whichever is most convenient for your operation) and install a strain relief to support and protect the I/O wiring. Avoid contact with any printed circuit boards. WARNING: Risk of equipment damage, personal injury, or death. For a proper and safe installation, make sure you meet the requirements in the following step. 4. See Figure E 1-3. Route the I/O wiring through the strain relief and the two ferrites from the ship-with kit to the I/O board terminal blocks. Make sure your installation meets these requirements: Use 0.34 0.25 mm 2 (22 24 AWG) stranded wire that is suitable for National Electrical Code (NEC) Class 1 remote control and signaling circuits. Output contacts are rated for 250 VAC, 2 A maximum. Use the proper length of wire and route the wires so they do not touch any of the printed circuit boards. Make sure the wires reach the I/O board terminal blocks when the electrical enclosure is opened. Position the ferrites as close to the rear panel as possible.

Additional Features The I/O board adds the following additional features that can be programmed using the SYSTEM SETTINGS controls: Auto Standby Timeout In Standby Timeout Remote Heaters On/Remote Pump Enable Rempote Pattern Select (Pattern control units only) Each feature is factory-set at zero (0), which means the feature is disabled. To program these features, refer to Programming SYSTEM SETTINGS Controls in the Installation section. Refer to Table E 1-3 for a description of how each feature works and a range of possible settings. Table E 1-3 SYSTEM SETTINGS Timeout Features Feature No. Feature Description Default Setting 30 Auto Standby Timeout 31 In Standby Timeout 34 Remote Heaters On/Remote Pump Enable 38 Lose Ready On/Remote Enable 51 Remote Pattern Select (Pattern control units only) Allows you to program the unit to automatically enter the standby mode and maintain heated zones at standby temperature setpoints if a gun is not fired during the specified period of time. The unit will remain in standby mode indefinitely unless a gun is fired or unless a value other than zero (0) is entered in Feature 31, In Standby Timeout. Allows you to program the unit to automatically exit the standby mode and enter the sleep mode (turn the heaters off) if a gun is not fired during the specified period of time. Allows you to remotely turn heaters on or to enable/disable the pump. This feature is only available on the enhanced I/O board. Allows the user to decide whether or not the control system should lose ready status when a cold zone is enabled thorugh the enhanced I/O board. Allows a pattern to be selected through the I/O board. If this feature is set to 1 or 2, patterns can be selected via inputs on the I/O board. Refer to Table E 1-4 for the various settings. This feature is only available on the enhanced I/O board. 0 (setting is off) 0 (setting is off) 0 (Remote Heaters On) 0 (setting is off) 0 (setting is off) Optional Settings 0 1440 (minutes) 0 1440 (minutes) 0 (Remote Heaters On) 1 (Remote Pump Enable) 0 (off) 1 (on) 1 or 2

E 1-9 4. I/O Board Replacement Use this procedure to replace a defective I/O board with a new I/O board. WARNING: Risk of equipment damage, personal injury, or death. Disconnect and lock out electrical power to the unit, including input/output (I/O) lines. 1. Turn off the unit; then disconnect and lock out electrical power to the unit, including I/O lines. 2. Open the electrical enclosure. Refer to Opening and Closing the Electrical Enclosure in the Control section. 3. Remove the screw that holds the board to its bracket inside the electrical enclosure. NOTE: A new bracket is included in the service kit. If desired, you can replace the existing bracket with this new bracket. 4. Label or note existing connections for later reference, then disconnect wires from the board and pull the board out of the XP5 card edge connector. 5. Remove the new board from its static-safe container, making sure to handle the board by its edges without touching pins, wires, or circuitry. 6. Carefully install the new board in the XP5 card edge connector and attach the board to the bracket with the screw provided in the service kit. Tighten the screw to 2.03 2.26 N m (18 20 in.-lb). 7. Reconnect wires to the new I/O board. Refer to Table E 1-1 (standard I/O boards) or Table E 1-2 (enhanced I/O boards) in Input/Output Connections for terminal connections. 8. Close and secure the electrical enclosure. Refer to Opening and Closing the Electrical Enclosure in the Control section. 9. Restore power to the unit and resume normal operation.
