J1 - Output - Varian 969-8988 Bedienungshandbuch

The following figure shows a typical contact logic input
connection and the related simplified circuit of the controller.
Typical Logic Input Connection
J1 – Output
Logic Output Connector
All the logic output from the controller must be
connected at P2 mating connector. The following table
describes the signals available on the connector.
Pins Name
15-8 Fault 0V = no fail
24V = fail
13-6 Start Configurable output.
Default setting (win.177 = 0): 24V
pump in RAMP state, 0V = other state.
If win.177 = 1: 0V = pump in stop or FAIL
status, 24V = other state
12-5 Low Speed 24V = low speed active
0V = low speed not active
11-4 R1 Programmable Set Point Out
Can be related to: Frequency, Power,
Time Status or Pressure.
See following figures for more details. All
the setting can be done by: front panel or
serial line (win.101 to 105 and 162).

A STOP command (by
front Panel or serial or
Start/stop input) reset
the FAIL status.
