Installation

CAUTION

Please observe the following to ensure that the CPS is not damaged during installation and operation:

– Protect the connections against dirt or moisture in

the medium to be measured and the surrounding air.

– Avoid subjecting the CPS to strong or violent vi-

brations.

– Condensation must not be allowed to get into the

housing. At subzero temperatures malfunctions/ failures due to icing can occur.

– When using silicone tubes, only use silicone tubes

which have been sufficiently cured.

▷

The switching pressure pS only corresponds to

the scale value SK on the hand wheel when the diaphram is vertical.

1 Mount the CPS using the Z-angle bracket.

CPS 0 – 4000

1 Attach the CPS itself using screws or bolt it using

the optional Z-angle bracket.

▷

If the CPS is directly attached, use a maximum of 2 screws to prevent stresses on the CPS.

CPS 00 – 4000 2 Attach 4.75 mm diameter tube to the positive or

negative pressure port.

For measuring positive pressure

▷ Attach the tube to the positive pressure port (+).

The negative pressure port is left open to ventilate

the upper chamber of the diaphragm.

GB-2

For measuring negative pressure

▷ Attach the tube to the negative pressure port (-).

The positive pressure port is left open to ventilate

the lower chamber of the diaphragm.

For measuring differential pressure

▷ Attach the tube with the higher pressure to the

positive pressure port (+), attach the tube with the lower pressure to the negative pressure port (-).

Adjusting the switching pressure p

▷

The switching pressure can be adjusted using the

hand wheel with scale. The switching pressure differs from the adjusted setpoint by a maximum of ± 15%, when it has been set for increasing pressure and with a vertical diaphragm.

1 Disconnect the system from the electrical power

supply.

2 Generate negative and/or positive pressure on

the CPS.

 Remove the CPS cover. 4 Check the contact position with a measuring

instrument.

COM

▷ If the CPS..G has switched a voltage > 24 V and

a current > 0.1 A once, the gold plating on the contacts will have been burnt through. It can then only be operated at this power rating or higher power rating.

▷ In the case of low switching capacities, as 24 V,

8 mA, for example, we recommend using an RC module (22 Ω, 1 μF) in air containing silicone or oil.

1 Disconnect the system from the electrical power

supply.

2 Remove the CPS cover.

▷

CPS 300, CPS 1000, CPS 3000: remove the cover for the connection terminals.

 Feed the cable through the cable gland into the

CPS.
