5.1 Install “Run Interlock” and “Run Enable” safety circuit on Bypass Control Board TB2
Note: Refer to wiring illustration on the next page terminal location.
a. Install a Run (Auto Mode) switch or jumper at Bypass Control Board terminals TB2 DI-1 to DI-10
Circuit closure is required for the motor to run in AUTO mode. Utilize an electrical contact from a building automation system
(BAS) or other remote controller for auto mode control.
b. Install a Run Enable (Safety) switch or jumper at Bypass Control Board terminals TB2 DI-2 to DI-10
The HOA keypad will display a “Safety Open FB01” fault and prevent bypass operation if this circuit is not closed. Connect
safety devices in a normally-closed series circuit, such as: freeze up thermostats, smoke/fi re sensors, high pressure limits,
temperature limits, or vibration detectors.
Note: FBO1 Fault will occur if this circuit is not closed.
c. Install a BAS interlock switch or jumper at DI-3 to DI-10
Building Automation System (BAS) Interlock. The HOA keypad will display an “INTRLOCK OPN” fault and prevent drive and
bypass operation if this circuit opens. The HOA keypad may also display “BAS Ilock-open” alarm or “BAS Ilock TO” if this
circuit opens.
Note: AL02 Fault will occur if this circuit is not closed.
