4.5 Remote and Local Control Place
The LOC/REM key is intended for switching between remote control place and local
control place.
The control place is the source of control where the frequency inverter can be started
and stopped. Every control place has its own parameter for selecting the frequency
reference source.
The remote-control place is determined by parameter and is indicated by an arrow on
I/O or BUS on the display of the keypad.
The local control place is always the keypad and is indicated by an arrow on KEYPAD
on the display of the keypad.
CAUTION!
Before removing the keypad from the vacuum pump, the control place must be reset
to remote control to avoid a fault message of the vacuum pump (error code 52 keypad
communication fault).
The fault massage is only resettable by using the keypad again to change the control
place!
