SQV 05.2 SQV 14.2 / SQRV 05.2
Description/cause
Motor protection tripped
No actuator reaction to operation commands within
the set reaction time.
Potentiometer is outside the permissible range.
Loss of signal analogue input 1
Loss of signal analogue input 2
Contrary to the configured direction of rotation and
the active operation command, the motor turns into
the wrong direction.
Motor protection: Fault within converter
Description/cause

Remedy
Cool down, wait.
If the fault indication display persists after cool-
ing down:
-
Set selector switch to position Local con-
trol (LOCAL) and reset fault indication via
push button RESET.
-
Execute reset command via fieldbus.
Check fuses.
Check movement at actuator.
Check device configuration:
Parameter Low limit Uspan M0832 must be less
than parameter Volt.level diff. potent. M0833.
Check wiring.
Check wiring.
Check operation command control.
For 3-phase AC current mains, activate phase
monitoring (parameter Adapt rotary dir. M0171).
Check device configuration setting (parameter
Closing rotation M0176).
To delete the fault indication: Disconnect actuator
controls from the mains and perform reboot.
Remedy
Check operation commands (reset/clear all op-
eration commands and send one operation
command only).
Set parameter Positioner to Function active.
Check setpoint.
