Pump Connector

A 30-cm cable is available to connect the controller to the
pump. The following figure shows the controller output con-
nector configuration with pins:
•
A-F = pump temperature sensor
•
B-C-D = 60 Vac 3-phase output to pump motor stator
•
E = EARTH PROTECTION
Controller-to-Pump Connector
If the temperature sensor is disconnected, the pump will not
start. To prevent damage to the pump when the temperature
exceeds 60° C, the sensor automatically cuts off the power
supply

J5 – GAUGE CONNECTOR
This connector is used to connect the "EyeSys Mini-IMG"
gauge with its extension cable (see orderable parts table).
The pressure can be read via serial line (WIN. 224) or by RE-
MOTE I/O on Programmable Analog Out (in this case, the
controller replicates the signal coming from the gauge).
The Mini-IMG gauge is intended for high vacuum use; there-
fore, with a pressure above 50 mTorr, the signal is misinter-
preted and a "false" pressure is displayed. Use a transition
gauge to check whether the reading is effectively below 50
mTorr.
