Spring Return
Floating
24 Vac/dc
1. Check Operation:
a. Connect wires 1 (red) and 2 (black) to a 24 Vac/dc power supply.
b. Apply a control signal (24 Vac/dc) to wire 6 (violet).
Allow the actuator shaft coupling to rotate from 0 to 90°.
c. Remove the control signal to wire 6 (violet).
d. Apply a control signal (24 Vac/dc) to wire 7 (orange).
Allow the actuator shaft coupling to rotate from 90° to 0°.
2. Check Spring Return:
a. Apply a control signal (24 Vac/dc) to wire 6 (violet).
Allow the actuator shaft coupling to rotate half way.
b. Disconnect wire 1 (red).
The spring returns the actuator shaft coupling to the fail-safe 0 position.
c. Connect wire 1 (red).
The actuator shaft coupling begins to move.
GPC32x
Two-Position
100 to 240 Vac
1. Check Operation:
a. Switch on 120 Vac power.
b. Allow the actuator shaft coupling to rotate from 0 to 90°.
2. Switch off power.
The actuator shaft coupling will return to the 0 position.
3. Check Spring Return:
a. Switch on 120 Vac power.
b. Allow the actuator shaft coupling to rotate halfway.
c. Switch off 120 Vac power.
The spring returns the actuator shaft coupling to the fail-safe 0 position.
Service
WARNING:
Do not open the actuator.
If the actuator is inoperative, replace the unit.
Troubleshooting
WARNING:
To avoid injury or loss of life, pay attention to any hazardous voltage
(For example, 120 Vac) when performing checks.
• Check that the wires are connected correctly.
• Check that DIP switch is set correctly, if used.
• Use a Digital Multimeter (DMM) to verify that the operating voltage is within range.
• If the actuator is not working, check the damper for blockage.
• If blocked, remove the obstacle and cycle the actuator power off and on. The
actuator should resume normal operating mode.
