CORRECTIVE ACTION
Adjust the opening limit switch. The
opening limit switch must be actuated
with the valve open.
Adjust 100% potentiometer on positioner
board.
When replacing a motor, wire markings
must be observed. In case of doubt,
check rotational direction. To reverse the
motor rotational direction, change over
wires 2 and 3 of the motor terminal strip.
Indications are only available with the
Actuator "on".
Check that the concerned indication relay
has been configured for torque limiter
indication. The jumper of the "I"
board is set to:
TS0 for opening torque limiter
TSC for closing torque limiter
The electronics only store the limiter data
if a manoeuvre is in progress. The
electronics further only stores the data for
the load limiter corresponding to the
rotational direction.
The torque limiter data are stored
electronically. To clear a torque limiter
memory, a reverse order must be sent.
Send a control signal on the input
Set the selector switch to "remote".
PROBLEM
The Actuator
does not stop
on the opening
limit switch
Indications are
inoperative
The torque
limiter
indications are
inoperative
The torque
limiter indication
does not return
to initial reading
once the torque
limiter is no
longer actuated.
A fault is
indicated but
the Actuator is
fully functional.
CAUSE
The opening limit switch is
misadjusted.
Position 100% is
misadjusted
The motor has been
unwired and rotates in the
reverse direction (motor
replacement)
The Actuator is "off"
Configuration incorrect
The load limiter has been
actuated manually.
Torque limiter data storage
The datum signal is not
present. In standard
configuration, the Actuator
indicates a fault and
remains in position
The selector switch is set
to "local" or "off" position. In
standard configuration the
Actuator indicates a fault.
