4.4.1 Connection of the model CPT6000 reference pressure sensor to the

CPH7650

WARNING!
EN
Mechanical damage through incorrect pressure sensor or applied
pressure
Disregarding this can lead to the destruction of the measuring instrument!
▶
▶
▶
For overpressure or gauge pressure sensors, the pressure compensation
vent can be found at the top of the sensor housing under the plastic fitting.
This vent (with integrated diaphragm) must always remain clear!
Only close the lid of the case once the connection cable from the CPH7650
to the CPT6000 reference sensor has been disconnected.
Only ever use the original WIKA sensor connection cable in the operation of CPT6000
■
reference pressure sensors.
The pump performance is independent of the pressure range of the selected
■
reference sensor. The operator must ensure that the CPT6000 reference sensor is not
over-pressured.

4.4.1.1 Electrical connection

The pressure calibrator and the reference pressure sensor are connected to each other
electrically using a separate connection cable. To electrically connect a model CPT6000
reference pressure sensor, the corresponding cable connector must be plugged in at the
sensor in accordance with the orientation guide. To disconnect the sensor, do not pull on
the cable, but rather only on the connector sleeve.
To connect it to the CPH7650, plug in the other end of the cable in accordance with the
orientation guide.

4.4.1.2 Mechanical connection

To make the mechanical connection of the CPT6000 reference pressure sensor, it must
be placed, connection thread first, in the sensor bracket of the instrument. Then the
sensor should be screwed tight.
(Tighten = turn clockwise; release = turn anticlockwise)
No further tools are required for this (only screw in hand-tight).
24
Only use model CPT6000 reference pressure sensors! Using other
sensors could damage both the pressure calibrator and the reference
pressure sensor.
To change the sensor, switch off the pressure calibrator and vent the
system. Before switching the instrument on, connect the sensor, otherwise
it may not be correctly identified by the instrument.
At the time the CPH7650 is switched on, the CPT6000 reference pressure
sensor must not be pressurised. There must be atmospheric pressure.
