SQM33.7) between 2 curve points in modulating mode.
2. Modulating operating ramp 64 seconds
The slope of the curve may be a maximum position change of 62° (30° for SQM33.6 and 18° for
SQM33.7) between 2 curve points in modulating mode.

Actuator was overloaded or mechanically twisted.
1. Check the setting of the actuator type (parameter 613.1)
2. Check to see if the actuator is blocked somewhere along its working range.
3. Check to see if the torque is sufficient for the application.

Relay contacts have welded
Test the contacts:
1. Unit connected to power: Fan output must be dead.
2. Disconnect power: Disconnect fan. No resistive connection between fan output and neutral
conductor allowed.
If one of the 2 tests fails, release the unit since contact have definitively welded and safety can
no longer be ensured.

Safety relay contacts have welded or external power supply fed to
safety relay
Test the contacts:
1. Unit connected to power: Fan output must be dead.
2. Disconnect power: Disconnect fan. No resistive connection between fan output and neutral
conductor allowed.
If one of the 2 tests fails, release the unit since contacts have definitively welded and safety can
no longer be ensured.
