Oil and Turbidity Detector TURBISCOPE
OR 52/5
OR 52/6
Important Notes
Electrical connection
To connect the light emitter/receiver, please use a screened,
multi-core control cable with a min. conductor size of 0.5
mm². For the light emitter e.g. 2 x 0.5 mm
2
and for the
receiver e.g. 4 x 0.5 mm
2
.
Connect the screen in the measuring transducer only once.
Max. line length between light emitter/receiver and measuring
transducer 50 m.
To use alarm contact 1 for an initial alarm and alarm contact
2 for the main alarm, for instance, set two different limit
values.
For condensate monitoring, alarm contact 1 can then be
used to control a three-way valve, which will discharge
the unusable condensate if the level of turbidity is too high
(alarm caused by ingress of oil or start-up protection). Alarm
contact 2 will then trigger the main alarm.
Note that alarm contacts 1 and 2 and the three-way switch-
over valve will not be switched over in the event of a mal-
function.
However, the malfunction can be included in the control
of the three-way switch-over valve as shown in the wiring
diagram
Fig. 6
.
Pneumatic valves can be actuated via solenoid valves.
Valves with a single-phase AC motor and max. power rating
of 50 VA (see wiring diagram
Fig.5
or
Fig. 6
) can also be
connected directly. Install a reversing contact in between in
the case of three-phase actuators.
