Replace a Servomotor
Replace a Potentiometer
Replacing the
While replacing a servomotor we can not ensure that the the adjusted
complete servomotor
curve in the FMS with the new motor results in the same damper position
as before
____________________________________________________________________
Therefor after replacing a servomotor the settings of the firing has to be
checekd over the whole range and all operation modes.
If necessary the curves in the FMS have to be readjusted.

iin a servomotor
____________________________________________________________________
Determine and note the actual value feedback at the lower position
switch block before replacing the potentiometer.
Dismantle the old potentiometer.
Install and adjust it, that the actual value feedback at the lower position
switch block has the same value as that you noticed before.
Install the potentiometer with positive locking according to the
specifications of the motor manufactor.
Control the settings of the firing and change as the case may be.
____________________________________________________________________
As the normally used potentiometers for the feedback may have different
values, there may be a difference in the position of the dampers as before.
Therefor after replacing a servomotor the settings of the firing has to be
checekd over the whole range and all operation modes.
If necessary the curves in the FMS have to be readjusted
