CAUTION !
1) The coil must only be supplied with 24V DC at a tolerance of ± 10% and a max. ripple of 10% (no supply via diode bridge).
Overvoltage or a ripple rate exceeding 10% can damage the electronics.
2) The max. current at pin 4 (or pin 7) is 500 mA. Pin 4 (or pin 7) is protected against short circuit and overload.
3) If a relay (inductive load) is connected to the pressure switch output, a freewheel diode or a varistor must be used.
4) Do not solder up the unused pins on the female connector.
5) The valve body must be grounded with the earthing terminal PE (dia. M4) (see p. 19: "Dimensions and weights").
6) A shielded cable must be used for protection against interference and EMC.
7) The input pressure must always be 1 bar above the maximum output pressure.
8) Always use a sufficiently filtered pressure supply (50 µm, free of condensates). Install the filter as close as possibly to
the PULSTRONIC. Dirt accumulations may cause malfunctions.
9) Take care when calibrating the product in your own company: Make sure not to damage any internal parts (electronics).

OPTION: SETPOINT - DIFFERENTIAL INPUT
The setpoint can be supplied as differential voltage between pin 3 and pin 4 of the connector (7-pin
connector only). Advantages: Interference in common mode are suppressed, several Pulstronic valves
using the same setpoint (current loop) can be connected in series.
Common-mode voltage: ±24 V at pin 3 and pin 4 referred to pin 2 (GND) of the connector (see page 1).
OPTION: EXTERNAL FEEDBACK VALUE INPUT
Instead of the internal pressure sensor, an external sensor for pressure, force, speed, position etc. is
used. The external feedback value is supplied to pin 4 (or pin 6) of the connector.
Voltage input 0 ... 10 V: 100 kΩ input resistance
Current input 0 ... 20 mA: 500 Ω shunt resistance
Current input 4 ... 20 mA: 500 Ω shunt resistance
The span and zero point must be adjusted as shown on manual MS-P305.
