PROBLEM
The actuator
does not follow
the input signal
The actuator
does not stop
on the closing limit
switch
The actuator
does not stop
on the closing limit
switch
The actuator
does not stop
on the opening limit
switch
No actuator
signalling
The torque limiter
indications
are inoperative
CAUSE
Motor has been rewired
(motor replacement i.e)
and rotates in the reverse
direction
The actuator is configured
for torque closing.
The closing limit switch
is misadjusted.
Position 0% is misadjusted
Motor has been rewired
(motor replacement i.e)
and rotates in the reverse
direction
The opening limit switch
is misadjusted.
Position 100%
is misadjusted
Motor has been rewired
(motor replacement i.e)
and rotates in the reverse
direction
The actuator is off
Incorrect configuration
The load limiter has been
actuated manually.
CORRECTIVE ACTION
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
1 and 2 of the motor terminal strip
in the travel switches compartment.
Check closing configuration
(switch 1 of the CI2701 board).
Adjust the closing limit switch. The closing
limit switch must be actuated with the valve
closed (even if the actuator is set for torque
closing).
Adjust actuator potentiometer
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 1 and 2
of the motor terminal strip in the travel
switches compartment.
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
1 and 2 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 CI2701 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.
