Information for the use of ramps In case of Ramp OFF or Cable break, any ramp started be-
Ramp ON: No signal at b20. fore will be canceled. Transition to the signal end value is ef-
fected by means of a step.
Ramp OFF: 8.5...40 V at b20 or connection between b22
and b20.

Project planning / maintenance instructions / additional information

– The amplifier card may only be unplugged and plugged when de-energized.
– The distance to aerial lines, radios and radar systems must be sufficient (> 1 m).
– Do not lay solenoid and signal lines near power cables.
– For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
– The valve solenoid must not be connected to free-wheeling diodes or other protective circuits.
– The cable lengths and cross-sections specified on page 4 must be complied with.
