PULSTRONIC

ELECTRICAL CONNECTION

PULSTRONIC valves are provided with a socket with 4 male pins. The electrical connection is made with a connector size 15 with 4
female pins and a cable gland. Cable entry dia.: 6 mm.

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% may damage the electronics.
!
2 ) The max. current at pin 4 is 500 mA. Pin 4 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 ) The valve must be grounded over the dia. M3 connection on the body with an external earthing terminal.
5 ) A shielded cable must be used for protection against interference and EMC.
6 ) When adjusting this device, carefully follow the instructions given in this installation manual and all ESD handling
procedures.
ANALOG SETPOINT
The PULSTRONIC valve with analog control is available in the following versions:
• Voltage setpoint :0 - 10 V (version: 0)
• Current setpoint :0 - 20 mA (version: 1)
4 - 20 mA (version: 2)
As a standard (version: 0), the PULSTRONIC valve is factory adjusted to be used with a setpoint of 0 - 10V.
On-site adjustment is possible by setting the zero point between -2V and +5V (240 kΩ input resistance).
Factory adjustments
PULSTRONIC valves are factory-adjusted as follows:
- 0 bar output pressure at a setpoint of 0 V (
- Span of 10 volts at maximum output pressure (100%) (
- Maximum proportional gain (
( ) Adjustment by customer for special application requirements is possible (see following pages).
*

SETTING PROCEDURE

First adjust the zero point, then - if necessary - the proportional gain.
1) Use potentiometer P4 to set the minimum output pressure for the minimum setpoint.
2) Use potentiometer P5 to reduce the proportional gain if necessary.
