SAVEx 07.2 SAVEx16.2/SARVEx 07.2
Description/cause
Contrary to the configured direction of rotation and
the active operation command, the motor turns into
the wrong direction.
Motor protection: Fault within converter
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.
Description/cause
Collective signal 13:
Possible causes:
Several operation commands (e.g. OPEN and
CLOSE simultaneously, or OPEN and SET-
POINT operation simultaneously)
A setpoint is present and the positioner is not
active
Selector switch is not in position REMOTE.
Operation via service interface (Bluetooth) and
AUMA CDT service software.
Actuator is in operation mode Disabled.
The EMERGENCY stop switch has been operated.
The motor control power supply (contactors or
thyristors) is disconnected.
Operation mode EMERGENCY is active (EMER-
GENCY signal was sent).
0 V are applied at the EMERGENCY input.
The actuator is controlled via the I/O interface (par-
allel).
Manual operation is activated.
An interlock is active.
By-pass function is interlocked.
Partial Valve Stroke Test (PVST) is active.
Temperature monitoring of PTC tripping device
The temperature monitoring of PTC tripping device must be connected and monitored
in an external system circuit. The signal is issued via an output contact.
Designation in the wiring diagram:
Active signal = NC contact open (NO contact = closed)
Active signal means: The PTC tripping device temperature is not within the permitted
temperature range.
SARVEx16.2 Control unit: electronic (MWG)
ACVExC 01.2 Non-Intrusive
Remedy
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 DMF trip torque OP parameter.
Check DMF fault level parameter.
Check DMF trip torque CL parameter.
Check DMF fault level parameter.
Remedy
Check operation commands (reset/clear all op-
eration commands and send one operation
command only).
Set parameter Positioner to Function active.
Check setpoint.
Press push button
vidual indications.
For a description of the individual signals, refer to
Manual (Operation and setting).
Set selector switch to position REMOTE.
Exit service software.
Check setting and status of function <Local controls
enable>.
Enable EMERGENCY stop switch.
Reset EMERGENCY stop state by means of
Reset command.
Detect cause for EMERGENCY signal.
Verify failure source.
Apply +24 V DC at EMERGENCY input.
Check I/O interface.
Start motor operation.
Check interlock signal.
Check states of main and by-pass valve.
Wait until PVST function is complete.
