Remote control
On the rear of the valve drive are sockets on a terminal strip. Signals can
be send and received by other devices via those sockets. The signals
are for example start signals of a injection valve or autosampler which is
connected to the START connector. All voltages between GROUND and
the corresponding input or output must be connected.

GND
Grounding of all inputs and outputs. Reference point
of the voltage at the signal inputs.
EVENT 1
TTL output (default setting)/
OC with external pull-up to 24 V (25 mA)
Levels:
passive 5 V
active 0 V
FLUSH IN
TTL-compatible input
Low-active

A signal (short-circuit to ground) sets the measuring
signal to zero. The measuring will be started again if
the signal is switched off.
