The HSS-outputs for the AutoCal valves are only available for the
Note
PMA1000 analyzer.
The pin assignment diagram and the status signal RS1 use the following definitions:
Electronics:
„
HSS1...4
High-Side-outputs 1...4 (voltage level 0/24V, 500mA to connect
magnetic valves or coupling relays directly)
RS
Relays (potential-free relay output, max. 24V/2A)
P_IN
Pressure sensor input (measures the pressure compensation during
operation)
P_OUT
Pressure sensor input (measures the pressure compensation during
operation)
∆P
Pressure difference between P_IN and P_OUT
