Connecting the EVENTS socket
You can control the states of individual contacts of the EVENTS socket
using SOP 9 "Setting the Control Signals (Events" on page 19.
Specifications of the Event signals
TTL (Transistor Transistor Logic) connections are to be connected only to
TTL compatible outputs (max. consumption: 40 mA, U
directed to GROUND.

Connecting the Analog/Error/Start Socket
The Analog/Error/Start terminal strip serves to send/receive either start or
error signals from/to other instruments. An additional voltage signal is
available for monitoring the system pressure or for controlling a slave
pump (see item ANALOG OUTPUT in "Using the SETUP Menu" on page
13). The ANALOG IN enables the external analog control of the pump.

Description
Activated by a 0 Volt or low signal or a short
circuit; I = 10 mA
IN
OC (open collector) output is active for 500 ms
When receiving a 0 V (error) signal, the
message Error signal was detected is
displayed and the pump is stopped; I
OC output is active until the error condition is
removed
Analog voltage signal gives either measured
system pressure (1 V per 40 MPa; Offset for 0
MPa is some mV) or a control voltage for slave
pump B. Adjustable voltage range between 1,
2, 5, and 10V maximum output.
Analog input signal controls flow rate; default 1
V per 1 ml/min for 10 ml head and 5 ml/min for
