Remedy
Bit 3 Valency ≥ 8
Curve too steep in terms of ramp rate
Check position differential between the curvepoints and the mod
ulating operating ramp setting
(parameter 544). 1.
Modulating operating ramp 32 seconds The slope of the curve may be a maximum position change of 31° (15° for SQM33.6 and 9° for 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.
Bit 4 Valency ≥ 16
Sectional deviation in comparison with last referencing
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 wo
rking 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 be
tween fan output and neutral
conductor allowed.
If one of the 2 tests fails, release the unit since contact have definit
ively welded and safety can no
longer be ensured.
