BIN 0 - 3
If the DIP switches were set to binary operation, then the connections BIN 0 -
BIN 2 are available as inputs. The output BIN 3 is active for the ports 1-6.
On the 12 port and 16 port valves, BIN 3 is defined as an input so that the ports
9-12 or 9-16 can be used.
Note
The binary input is inactive during the change of the valve port. This can be
used to control further external devices.
Binary Code
A binary code is entered during binary control so that the valve can be set exter-
nally in the correct position (nominal position).
Prerequisites
The DIP switch of the device was set for the binary control.

Signal Explanation
GROUND Ground connection for start and error signals
HOME/POS. 1 Connection for short circuit for creating a switch signal:

Valve drive is set to position 1.
FORWARD/
LOADING Connection for short circuit for creating a switch signal, exam-
ple for output:

LOADING

Move to the next higher port of the valve, e. g. from posi-
tion 2 to position 3
BACKWARD/
INJECTING Connection for short circuit for creating a switch signal, exam-
ple for output:

INJECTING

Move to the next lower port of the valve, e. g. from position
6 to position 5
OUT Connection for short circuit (no current)

INJECTING, port 1, low-impedance

LOADING, port 2-6 or 2-16, high-impedance
