13. If the GCC accepts the change, an acknowledging message appears. Release the switch and
close the front panel.

Config).
15. Verify that changes have been accepted and then press F1 as necessary to return to the
Background screen.
If the GCC accepts the new configuration settings, it displays them on the screen in the appropriate
fields. If it does not accept them, the field settings do not change and a *PRES BD ALARM* signal is
displayed. If you do not hold down the switch long enough, a *PRES BD ALARM* signal will display
and the new settings will not be accepted. Check the established limits for the settings in the Data
Package and try again.

Configuring SWITCH

SWITCH displayed in the Config column on the Manual Pressure Control Mode screen or the
Pressure Config Table screen indicates a zone with a pressure Set Point that is not intended to be
changed. If it becomes necessary to change the Set Point, perform the following steps.
Before opening any analyzer doors, ensure the area is safe and hazard-free, and
will remain so the entire time the analyzer is open. If the analyzer has X Purge,
operate the override function as described in "X Purge Override Option."
1. Open the GCC front panel.
2. On the Background screen press F2 (Manual Control).
3. On the Manual Control Mode screen press F4 (Pres & Temp Control).
4. On the Pres & Temp Control screen, cursor to PRES CONTROL and then press F2 (Manual
Pressure Control).
5. On the Manual Pressure Control Mode screen, cursor to the Zone # field and enter the desired
zone number (1 - 5).
6. Cursor to the Set Point field and enter the setpoint pressure (the required operating pressure for
the component in this zone).
7. Press F2 (Accept Control Point). The GCC displays "Hold Switch on Pres Bd to Accept SP."
8. Hold down the switch on the Electronic Pressure Control PCB. The GCC displays the message
"Are You Sure?"
9. Continue holding the switch down and press Y on the keyboard to execute the change. The GCC
sends the new setting to the Electronic Pressure Control Multibus PCB where it is checked
against the established limits (this only takes a few seconds).
10. If the new pressure is accepted, it is displayed on the screen in the Set Point field. Release the
switch and close the front panel.
