Description
F9.734 Pressure Switches

These pressure switches measure the pressure in hydraulic systems and convert it into electrical signals.
All devices are provided with 2 outputs. While output 1 is a freely programmable switching output, output 2 can be selected as analogue output, switching output or alarm output. The switching and reset points, the output logic and time delays can be programmed through the membrane keyboard. Display and analogue output are equipped with adjustable damping for dynamic measurements.

Versions
There are 2 different versions, which differ in the type of adjustment option.
Pressure switch with classic parameterisation
Part no.  9740 049A

The desired switching and reset points are entered using a classic 3-button control panel.
This version can be parameterised conventionally for all applications, independent of the pressurisation of the pressure switch. 
Pressure switch with TEACH-IN function
Part no.  9740 050A

With the Teach-In procedure, a present pressure is stored in the pressure switch by pressing a button (Enter/Set button). This pressure value corresponds to the operating pressure.
The pressure switch automatically calculates the optimum switching and reset point for output 1 (e.g.  pump control/sequence control) and output 2 (e.g. machine control / release).
It is useful to adjust the operating pressure with the pressure relief valve. Detailed instructions can be found in the operating manual BA 9734.
