CBOX936
INSTALLATION AND PROGRAMMING MANUAL
22
1. After applying battery power to the 936 control board the display will show...
a) a chasing cursor (to confirm all LEDs are functional), followed by...
b) the firmware version, then...
c) the display will flash “bb” to indicate that the control board is scanning for monitored safety devices.
2. If safety devices (such as photo eyes) are found and determined to be functional, then display defaults
to a flashing “Lr” indicating the board is ready to “Learn” the gate limits and you may proceed to
INSTRUCTION 11.
3.
If no safety devices are attached or functioning, display will show “
E1”.
4.
If using the BlueBUS photo eyes when error is displayed, check for BlueBUS wiring errors and/or observe
diagnostic LEDs per INSTRUCTION 13 to determine problem. If using the reflective photo eye with
reflector, refer to the separate instructions included in the kit for troubleshooting instructions.
5. To reset the board after a scanning error (E1), remove power from the board (unplug battery connector)
then after a few seconds reapply power (plug in battery connector).
6. Once safety devices (such as photo eyes) are found and determined to be functional, proceed to
INSTRUCTION 11.
7. If safety devices provided in the kit are determined to be defective, contact Nice technical support.

POWER UP CONTROL BOARD
NOTES:
•
If a gate moves in opposite direction from what is expected, reverse the motor power lead wiring (reverse
red & black wires) for that motor connection.
• If the wrong limit LED lights (i.e. the close LED lights when gate at open limit), reverse the limit wires (reverse
orange and white) for that motor connection.
8.2 GATE LIMIT LEARNING PROCEDURE
Before performing the fine adjustment to gate limits, the 936 control board must first “learn” the rough limits
and the number of actuator motors used to move the gate, as described below.
IMPORTANT!
If configuring a dual gate system, only one actuator harness should be connected at a time to the control
board at this point. Do NOT press the LEARN button until Step 9 in the instructions below.
