Electrical data for the diaphragm breakage sensor
a) Switch contact
30 V DC/1 A	or	125 V AC/0.6 A	or	250 V AC/0.3 A

The diaphragm sensor is a N/C relay.

IMPORTANT

Before commencing operation, install the provided diaphragm breakage sensor together with the gasket (Item159) and make the electrical connections.

NOTE

¥For safety reasons it is advisable to connect a safe low voltage (e.g. EN 60335-1 (SELV)).

¥The cable priority is arbitrary.

b) Namur sensor, intrinsically

5-25 V DC, Namur type and/or DIN 19234, zero volt design. Rated voltage: 8 V DC (Ri ~ 1 kΩ)

Power consumption:

Active surface, uncovered > 3 mA Active surface, covered < 2 mA

Rated switching distance: 1.5 mm

The monitor/feeder must be capable of evaluating current changes in order to indicate diaphragm rupture!

WARNING

¥EX-pump only: Installations in potentially explosive atmospheres must be inspected by an Òaccredited qualifiedÓ person. This applies in particular also for intrinsically safe electrical circuits.

¥EX-pump only: observe documents supplied with the sensor!

IMPORTANT

¥Before commencing operation, install the provided diaphragm breakage sensor together with the gasket (Item159) and make the electrical connections.

¥For pump without EX protection: For safety reasons it is advisable to connect a safe low voltage (e.g. EN 60335-1 (SELV)).
