Operating instructions
4.3.11 DIP switches
With the 4 single switches (S1/1 to S1/4) the sole-
noids can be switched separately (S1/2, S1/3) and
the operating mode can be changed from “normal
operation” to “construction time use” (S1/1, S1/4).
Do not turn on/off S1/1 and S1/4 unless power is
off.
When S1/2 and S1/3 are switched off simultaneous-
ly, a reset operation will be executed.
4.3.12 LEDs
Some LEDs are used to show the state of the EOS
inputs and outputs:
The other LEDs show the status of the board and
solenoids:
*) flashing in the same interval but with only short
flashing of the LED indicates that the mechanical
brake has reached its wear limit.
**) if triggered via TRIP the LEDs show which side of
the solenoids has tripped by flashing briefly.
4.3.13 Bus interface
This interface (X6) is reserved for future extensions.
