Operation
Note:
Low pressure gauges must be 'enabled' by the Logic Interface before TIC can turn them ON and OFF. This is
done either by fitting a link across the appropriate pins on the mating connector, or using an external
switch.
The logic interface plug supplied with the TIC has links for this purpose.
If System Interlock (SYSI) is active, pressing the 'Cycle' ( ) button will not switch on low pressure gauges.
Conversely, if SYSI is opened during the vacuum cycle, all connected controllable components will be
switched OFF.
