SA 07.2 SA 16.2/SAR 07.2
Description/cause
The phase conductors L1, L2 and L3 are connected
in the wrong sequence.
Only applicable if connected to a 3-ph AC system.
Due to insufficient mains quality, the controls cannot
detect the phase sequence (sequence of phase
conductors L1, L2 and L3) within the pre-set time
frame provided for monitoring.
Motor protection tripped
No actuator reaction to operation commands within
the set reaction time.
Potentiometer is outside the permissible range.
LPV: Lift Plug Valve function
The master actuator signals a fault
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.
Synchronous link function: Actual position values
of master actuator and slave actuator are not syn-
chronous (excessive deviation).
Synchronous link function: Slave actuator is not
ready.
Synchronous link function: Signal loss of actual po-
sition value from master actuator or slave actuator.
The torque in direction OPEN, measured at the
output drive shaft using the torque measurement
flange, is too high.
The torque in direction CLOSE, measured at the
output drive shaft using the torque measurement
flange, is too high.

Remedy
Correct the sequence of the phase conductors L1,
L2 and L3 by exchanging two phases.
Check mains voltage.
For 3-phase/1-phase AC current, the permiss-
ible variation of the mains voltage is ±10 %
(option ±30 %). The permissible variation of the
mains voltage is ±5 %
Check parameter Tripping time M0172, extend
time frame if required.
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.
Check Deviation MA/SA [%] parameter.
Check Deviation MA/SA [%] parameter.
Check wiring.
Check DMF trip torque OP parameter.
Check DMF fault level parameter.
Check DMF trip torque CL parameter.
Check DMF fault level parameter.
