Wiring guidelines:
• Relays and solenoids operating from the same power
supply have to be damped by surge protection elements.
• Screened wiring of analogue signals are mandatory.
• Do not install this unit in areas with high EMI (i.e. motor
cables, AC/DC commutator motors, frequency
converters....).
Start up:
• Adjusting of maximum current via internal DILswitches.
Attention: valve solenoids can be
damaged by high current.
• Offset (zero point) adjustment . This module is
pre-adjusted, often no further adjustment is necessary.
• Dither adjustment. The Dither amplitude have to
be optimised to get best valve or drive performance.
Dither adjustment will reduce hysteresis.
The output characteristic describes maximally drivable output current associated at the load resistance
