SEPARIX-Control CT measuring transducer

4.1

Design and function

The SEPARIX-Control CT measuring transducer serves as power supply and signal pro-
cessing of the connected SEPARIX-C L Plus interface sensor and/or the SEPARIX-T L Plus
high-level sensor and together with the sensors forms a warning system for light liquid
separators.
With the interface sensor, the warning system reacts to the thickness of the oil / light liq-
uid layer. It generates an alarm signal before the automatic closure device shuts off the
outlet of the separator due to a high oil / light liquid level.
With the high-level sensor, the warning system reacts to the fluid height (whether oil, light
fluid or water) in the separator. It generates an alarm signal whenever the liquid level in
the separator rises above an impermissible threshold, e.g. due to reverse flow of the sepa-
rator outlet, or because the automatic closure device has shut off the outlet of the
separator due to a high oil / light liquid layer.
The two connectable sensors can individually be activated or deactivated in the SEPARIX-
Control CT.

Faults and alarms are signalled visually by LEDs (1-3) and audibly by a buzzer. Two potential-
free changeover contacts permit the connection of external alarm transmitters and are
switched in the event of an alarm.
Two membrane buttons (4/5) are used to acknowledge faults and alarms as well as to test
the alarm signalling behaviour of the device and, where applicable, connected alarm trans-
mitters. The alarm signalling of the device can be configured individually using the
"Options" DIP switch (see section 4.2).
