WARNING:
To avoid injury or loss of life, pay attention to any hazardous voltage
(Example: 120 Vac) when performing checks.
• Check that the wires are connected correctly.
• Check that auxiliary switches, DIP-switches, and Offset/Span are set correctly.
• Set the DMM dial to Vac and 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.
