Reactive Factor Controller CX plus

500 Settings ALARM

Almost all alarms and monitoring functions can be activated / deactivated and limit values can be set
in the alarm menu.

600 Reset menu

Allows resetting all made settings, values saved by the controller and counters. Additionally, it is
possible to call up the software version of the device and to set the password (PIN) for the expert
setup menu.

700 Settings MODBUS (only option -MB)

Contains settings in order to parametrise the MODBUS-RTU communication interface (RS485).

NOTE:

This submenu is only available with the option -MB.
