Troubleshooting Of Positioner Version - Bernard Integral+ Commissioning Instructions

14 TROUBLESHOOTING ON POSITIONER VERSION
In case of doubt as to the unit's functionality, firstly set the local/remote selector switch to local
and actuate the local open/close controls.
PROBLEM
No operation
The actuator
operates
in local open/close
control mode,
not in positioner mode
CAUSE
Actuator power supply
An emergency control
command is present and
inhibits all other com-
mands.
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
Local/remote selector
switch set to local
or to off
An auto/on-off control
order is present
and inhibits the positioner
CORRECTIVE ACTION
Check the power supply voltage (terminals 1, 2,
3 in three-phase voltage or 0,1 in single phase).
The voltage is specified on the identification
plate.
Check that the actuator receives
no emergency control command.
With the unit off , jumper 27 may
be removed from the CI2701 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 of CI2701 board
Check position of jumper 100 on the C2701
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 supports
16-17-18 and only one jumper on supports
19-20-21
Set the local/remote selector switch
to remote to use the positioner (even when
the positioner is set to manual).
Check that the actuator receives no Auto/
on-off control command.
Disconnect this remote control (terminal 11)
as required for confirmation.
