24 Installation and connection
HOME
If the valve is controlled by HOME , it has priority over control via
RS-232 or manual operation. As long as the switch-off signal is
not cancelled, the valve cannot be started. The indicator of the
position flashes to indicate that the start of the valve is pre-
vented by an external signal.
BIN 0–3
If the DIP switches were set to binary operation, then the con-
nections BIN 0–BIN 2 are available as inputs. The output BIN 3
is active in the valve positions 1–6.
On the 13P/1C and 17P/1C valves, BIN 3 is defined as an input
so that the positions 9–12 or 9–16 can be used.
Note: The binary input is inactive during the change of the
valve position. This can be used to control further
external devices.
Signal Explanation
GROUND Ground connection for start and error sig-
nals
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, example for output:

LOADING

Set the position of the valve to the next
higher one, e. g. from position 2 to posi-
tion 3
BACKWARD/
INJECTING Connection for short circuit for creating
a switch signal, example for output:

INJECTING

Set the position of the valve to the next
lower one, e. g. from position 6 to posi-
tion 5
OUT Connection for short circuit (no current)

INJECTING, position 1, low-impedance

LOADING, position 2–6 or 2–16, high-
impedance
