Project planning information
The amplifier card may only be unplugged and plugged when de-energized.
The distance to aerial lines, radios, and radar systems has to be at least 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 protection circuits.
The cable lengths and cross-sections specified in the technical data must be complied with.
Mounting
Wiring information
Power zero b2 and control zero b12 are to be bridged.
If the power supply unit is < 1 m away, directly to DIN connector.
In case of distances > 1 m, lead the control zero separately to the ground.
Commissioning
Information on ramp use
Ramp ON: No signal at b20.
Ramp OFF: 8.5...40 V at b20 or connection between b22 and b20.
In case of ramp OFF or cable break, any ramp started before will be canceled. Transition to the signal end value is realized in one step.
