Error treatment

5.3.1 Reaction of the CPV valve terminal to faults

5-8
Reaction to faults in the control system
The CP valves and any existing electric outputs are switched
off in the event of a fault after the following times:
Baud rate (kBaud)
31.25
62.5
187.5
375
Fig. 5/7: Switch-off times of CP valve terminals and outputs
during faults (depending on baud rate)
Please note
If the outputs are reset after PLC stop, field bus interrup-
tion or fault, please observe the following:
– single-solenoid valves move to the basic position
– double-solenoid valves remain in the current position
– mid-position valves move to the mid-position (depend-
ing on valve type: pressurized, exhausted or blocked).
Switch-off time
