If the optional controller pop-up status is enabled when the QX detects battery failure, a pop-up status

dialog is displayed on the current screen to alert the operator of the Ok status change. The operator can

then invoke the system menu diagnostic sub-menu to determine the cause of the loss of Ok status.

Alternately, the screen designer can also place a graphic object or audible indicator (through ladder logic)

in the application (referenced to OCS register %SR55.13) to alert the operator of battery failure.

It is also suggested that the system menu diagnostic sub-menu battery indicator be checked on a regular

basis to verify its operation.

15.2.2 Battery Replacement

The QX uses a replaceable coin lithium battery available as Horner APG part number BAT00011.

Below are the steps to replace the battery.

1. It is strongly recommended that the user program and any data stored in retentive memory be

backed up using CSCAPE’s upload function or the removable media (CompactFlash) save

program function before starting this procedure.

The QX maintains power on battery-backed retentive memory for 3 minutes after

the unit is powered off. If the battery change procedure exceeds that time, the

application and its data will be lost.

2. Disconnect all power from the QX unit including I/O power.

3. If installed, remove the optional HE500VIM400 Video Input Module.

4. Locate battery access door (Fig. 13.1).

5. Open the battery access door by squeezing in on the latch and lifting up on the door (Fig. 13.2).

6. Disconnect and remove the old battery. Use care in removing the battery from the holder without

breaking the retaining ears.

7. Dispose of the battery properly; see the above warning on disposal regulations.

8. Slide the new battery into the holder. Reconnect the battery connector making sure it is inserted

properly (connector is keyed).

9. Apply power to the unit. Check that the battery error is no longer reported. If the unit still reports

the error, remove the battery immediately and contact Technical Support (page

92).

10. Record the installation date on the label on the back of the battery access door.

Warning: Disposal of lithium batteries must be done in accordance with federal, state, and local

regulations. Be sure to consult with the appropriate regulatory agencies before disposing batteries. In

addition, do not

re-charge, disassemble, heat or incinerate lithium batteries.

Warning: Do not make substitutions for the battery. Be sure to only use the authorized part numbe

to replace the battery.

Warning: Lithium Batteries may explode or catch fire if mistreated

Do not recharge, disassemble, heat above 100 deg.C (212 deg.F) incinerate, or puncture.
