Mode of operation
The measuring transducer SEPARIX-Control CT is used for the power supply and analysis of the oil separator
sensor SEPARIX-C .. and the high-level sensor SEPARIX-T .. . Alarms and malfunctions are signalled optically
and acoustically by means of light-emitting diodes and a built-in buzzer. External alarm transmitters can be
connected via potential-free changeover contacts, which are switched in the case of an alarm. The acoustic
alarm can be acknowledged using the Alarm button. The optical alarm remains on until the cause of the
alarm has been eliminated. An internal switch can be used for an optional setting to determine whether or
not external alarm transmitters can be reset at the potential-free changeover contacts. Additional internal
setting options are the automatic alarm repeating function after 24 hours, changeover contact switched in
the alarm or normal state, and whether the alarm is to be activated for the detection of liquid or air. The
function test for the internal and external alarm functions can be carried out using the Test button.

Installation
Connecting the auxiliary power, the oil separator sensor, the high-level sensor and an optional, external
alarm transmitter must be carried out according to the connection diagram. The maximum values for the
operating parameters mentioned on the wiring diagram must be observed.
Wiring work may only be performed with the equipment in de-energized condition. The special VDE
regulations and the local installation regulations must be observed.

Operating instructions
Before being put into service, all devices must be checked with respect to correct connection and proper
operation. The electrical power supply, including the supply of the downstream devices, must be checked.
The general operating instructions for the devices being used must be observed. The measuring transducer
is maintenance-free.
