CORRECTIVE ACTION
Set the local/remote selector switch to
remote.
Check that a shunt is present at the client
terminal strip between terminals 31 and
32.
Check fuse FU3 on the "I" board.
Check connection in voltage control
mode:
Voltage 10 to 55 V: Terminal strip 31
Voltage 55 to 250 V: Terminal strip 30
Set the local/remote selector switch to
local.
Check that the Actuator receives no local
control inhibit command.
With the unit "off", the local control inhibit
wire, connected to terminal 37 may be
removed to carry out a functional check of
the Actuator.
Check the rotational direction
configuration. Switch #7 of the "I"
board:
Position A: clockwise closing
Position B: counterclockwise closing
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.
Check closing configuration (switch 1 of
the "I" 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).
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.
Adjust the opening limit switch. The
opening limit switch must be actuated
with the valve open.
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.
PROBLEM
The actuator
operates in
local mode, not
in remote
mode
The actuator
operates in
remote mode,
not in local
mode
The actuator
does not rotate
in the correct
rotational
direction
The Actuator
does not stop
on the closing
limit switch
The Actuator
does not stop
on the opening
limit switch
CAUSE
Local/remote selector
switch set to local or to off
Contact control: no voltage
across terminals 32 and
33.
Voltage control:
inappropriate input voltage.
Local/remote selector
switch set to remote or to
off
A local control inhibit
command is present.
Configuration incorrect
The motor has been
unwired and rotates in the
reverse direction (motor
replacement)
The Actuator is configured
for torque closing.
The closing limit switch is
misadjusted.
The motor has been
unwired and rotates in the
reverse direction (motor
replacement)
The opening limit switch is
misadjusted.
The motor has been
unwired and rotates in the
reverse direction (motor
replacement)
