External Interlock

Systems that may be affected during drive fault conditions should be interlocked with the drive fault output and ready signal.

Annunciation Contact Outputs

Annunciation contacts for customer use are provided at terminal blocks TB1 as indicated in
are used to indicate the status of bypass operation. Contacts are rated for 2 Amps, 24 Vdc/120 Vac +/- 15% maximum.

The function of output relays DO-7 through DO-10 may be reprogrammed via bypass parameters Z2-23 through Z2-26. These
form C dry contact relays are for customer use in annunciation to building automation systems (BAS) or other circuits. Each
contact is rated for 2 amps at 120 Vac.
Refer to Z2-01 to Z2-08: Digital Input 1 to 8 Function Select on page 174
of annunciation contacts.

Building Automation System Run/Stop Circuit

DI-1 (TB2-1 by default setting in Z2-01) is available to connect the normally open (N.O.) Run/Stop contact from a BAS or
other remote controller for auto mode control.
These terminals must have contact closure for the motor to run in AUTO mode.
u

Safety Interlock Circuit

DI-2 (TB2-2 by default setting in Z2-02) is provided to connect safety devices in a normally-closed series circuit, such as:
freeze up thermostats, smoke/fire sensors, high pressure limits, temperature limits or vibration detectors.
The HOA keypad will display the status "Safety Open", and trigger a Safety Open fault if a N.C. safety circuit is not closed
between DI-2 and IG24 (TB2-10) on PCB A2 at power-up with a Run command in HAND or AUTO mode. An open circuit
between DI-2 and IG24 will prevent bypass operation.
Take one of the following steps to ensure proper operation prior to startup:
1.
Install a N.C. safety circuit between DI-2 and IG24 on PCB A2.
2.
Install a jumper between DI-2 and IG24 (on PCB A2. A normally-closed safety circuit may also be used in place of
this jumper.

Building Automation System Interlock Circuit (Drive and Bypass Enable Input)

The HOA keypad will display the status "INTRLOCK OPN" and possibly a "BAS Ilock-open" alarm or "BAS Ilock TO"
fault if a N.C. safety circuit is not closed between DI-3 (TB2-3 by default setting of Z2-03) and IG24 on PCB A2 at power-
up with a Run command in HAND or AUTO mode. An open circuit between TB2-3 and IG24 (TB2-10) will prevent bypass
operation.
Take one of the following steps to ensure proper operation prior to startup:
1.
Install a N.C. BAS Interlock Circuit/Damper Interlock between DI-3 and IG24 on PCB A2.
2.
Install a jumper between DI-3 and IG24 on PCB A2. A normally-closed BAS interlock may also be used in place of
this jumper.
