1. Product Description

2. Starting operations

Intended Applications

- The pressure switch / trip amplifier is a device to monitor system pressure, temperature,
flow, level, etc. and has four switching outputs and one analog output.

- The pressure switch is only to be installed in systems where the maximum pressure Pmax is
not exceeded (according to the values on the type label).

- Attention: This device is not designed to be used as the only safety relevant element in
pressurized systems according PED 97/23/EC.

Only assemble or disassemble the device when depressurized!

- The pressure switch should be installed and operated only by authorized personel.

- Front cover and device bottom form a function unit. Exchanging the parts can result in
measuring errors or malfunctioning. See serial number inside the front cover. For wall
mounting, remove the four front cover screws and the front cover, then fasten the device with
four screws to the wall, and finally remount the front cover. To damp strong vibrations shock,
mounts must be used.

- Mount the pressure connection (G 1/4 female) of the PSW3000 to the pressure system with a
flexible pipe and tighten with a 45 Nm torque. For pressure peaks damping, screws must be
used.

- The electrical connection (supply, analog output switching contacts) must be carried out
according to the connection tables depicted on the top of the device by removing the cover
cap and insert the cable through the cable gland PG 13,5. If required, additional cable glands
can be installed in the cover cap by breaking out the perforated cavities.

- The electrical connection must be carried out in accordance with the VDE 0100 regulations. In
order to ensure trouble-free operation it is essential to connect the protective lead.

When operating from 230 V AC loads at the switch contacts independent cables must be
installed for supply and switches (cover cap with two cable screw connections).

- If inductive loads (magnets, contactors, etc.) are connected to the switch relays, suitable
protective devices (varistors etc.) must be provided.
