This module is also used for elevator control. Note: Do not use any power supply other than the KT-PC4204 to repower the Combus. If a power supply other than the KT-PC4204 is used, the Combus repower function will not operate as intended. 2. Specifications Current Draw: 30 mA (from Combus) 16VAC/40VA transformer required Maximum 7Ah battery required Connects to the controller via 4-wire Combus Four programmable relay contacts rated 2A, 30VDC AUX current: 1.0A max. Tamper contact input Can be used to repower the combus Can be used for elevator control 3. Installing the KT-PC4204 3.1. Unpacking The KT-PC4204 package should include the following parts/items: One (1) KT-PC4204 circuit board One (1) ground wire assembly Five (5) plastic standoffs One (1) 5A replacement fuse One (1) installation instructions sheet 3.2. Mounting The KT-PC4204 should be located inside a compatible cabinet (Kantech part no. KT-4051CAB), mounted in a dry and secure location. Preferably, it should be placed at a convenient distance from the connected devices. Perform the following steps to mount the unit: 1. Press the five (5) plastic standoffs through the mounting holes at back of the cabinet, 2. Secure the cabinet to the wall in the desired location. Use appropriate wall anchors when securing the cabinet to drywall, plaster, concrete, brick or other surfaces, 3. Press the circuit board into the plastic standoffs to secure the module to the cabinet. Once the unit is mounted, wiring may be started. 3.3. Installation and Wiring Before beginning to wire the unit, ensure that all power (AC transformer and battery) is disconnected from the KT-300 controller. Perform the following steps to complete wiring: 1. Connect the four Combus wires to the KT-PC4204. Connect the red, black, yellow and green Combus wires to the RED, BLK, YEL and GRN terminals, respectively. If the module is being used for Combus Repower, connect the Combus wires according to the following diagram. For this option, Jumper J1 must also be set for “Combus Relay.” 2. Complete all output wiring, 3. Connect the external tamper switch, if used. Consult the above wiring diagrams for further information.

Applying Power After all wiring is completed, apply power to the KT -300. Connect the battery leads to the battery, then connect the AC transformer. Then, connect power to the KT-PC4204: the battery leads followed by the AC transformer. Note: Do not connect the power until all wiring is complete. 4. Assigning the KT-PC4204 module Once all wiring is complete, the module must be assigned to the system. To assign the module, perform the following steps: 1. Establish communication between the PC and the controller, 2. Remove the tamper switch wire (or only the wire if tamper switch is not used), 3. A serial number should be displayed on the screen, in the same window where is the serial number appears, you should see the type of module and on which controller it is connected, 4. From the software, select the functionality of the module and enter the serial number in the appropriate field (see your software reference manual under controller definition -- Assigning modules for more details), 5. If the module is used in “repower” mode, assign an “all valid” schedule to relay 1 and assign the module’s functionality to “relay 1 to 4” in your software. Note: Don't forget to reconnect the tamper switch (or the wire, if there is no tamper switch). Note: If the module is uses as a "repower” module, ensure that Jumper J1 is set to "Combus Relay ” position.
