20
CAUSE
Actuator power supply
A local control inhibit
command is present.
An emergency control
command is present
and inhibits all other
commands.
Fuse blown
Power supply type
configuration
Tripping of motor thermal
protective device
The declutchable manual
control handwheel
remained engaged (only
on versions with electrical
safety contact)
Configuration jumpers
are incorrectly
set or missing
CORRECTIVE ACTION
Check the power supply voltage (terminals 1,
2, 3 in 3 PH voltage or 0, 1 in single phase).
The voltage is specified on the identification
plate.
Check that the actuator receives no local
control inhibit command.
With the unit off , the local control inhibit
wire, connected to terminal 11 may
be removed to carry out a functional check
of the actuator.
Check that the actuator receives
no emergency command.
With the unit off , jumper #27
may be removed from the INTEGRAL+
board, taking care to record its position
to make sure it is replaced at the correct
location. With the jumper removed, the ESD
function is inhibited, and a functional check
of the actuator can be carried out.
Return the jumper to original location.
Check fuses and replace as required.
Check position of jumper 100 on the CI2701
board.
Three-phase: position T
Single-phase or DC: position M
The TH light on the CI2701 board
configuration panel indicates thermal
tripping of thermal protective device.
The actuator will again be available after
the motor has cooled off.
Check that the handwheel is in disengaged
position.
There must be 11 jumpers on the CI2701
board.
There shall be only one jumper on jumper
16-17-18 support and only one jumper
on jumper 19-20-21 support.
