Note Refer to Optional Valve Failsafe Battery Back-Up for more information.
To be sure that the 651 unit has recognized the optional battery back-up module, or to view the
actual battery voltage and the current valve configuration without entering the software menus
(regardless of whether you are using Local or Remote operation):
1. Be sure that the default Pressure and Position display screen appears on the display:
PRES 4.90 Torr
POS 35.0 %
2. Press the [ ] key one time.
If the battery back-up module has been recognized, the screen displays:
BATTERY 13.5V
BACK-UP: OPEN
This screen allows you to view the actual battery voltage and the current valve
configuration. The valve configuration cannot be changed from this screen. Refer to
How To Set the Operating Parameters , step 18, for instructions on how to change the
valve configuration; the battery voltage cannot be adjusted. Press any key to return to
the default
