Replacing the battery

A lithium battery is used as a keep alive voltage for the volatile memory (RAM) that contains the controller

configuration. The battery is installed in a compartment on the CPU module. Follow the steps in the table

below to replace the CPU battery.

CAUTION

The battery used in this device may present a risk of fire or chemical burn if mistreated. Do not

recharge, disassemble, heat above 212 °F (100 °C), or incinerate. Replace battery with

Tadiran TL-5101/SBP only. Use of another battery may present a risk of fire or explosion.

Step Action

1Locate the battery and the battery compartment location on the CPU module. See Figure 36.

2Using a Phillips-head screwdriver, loosen the screw and remove the battery compartment

cover.

3For the standard CPU module –

• Using a screwdriver, insert it through the screw hole on the front and carefully pry the

battery out of its holder. Carefully remove battery from the holder.

For the CPU module option –

• The battery holder is contained on the battery compartment cover. See figure. Carefully

remove battery from the holder.

4Observing the correct polarity, insert a new battery into the holder.

5Verify that the LoBATT LED is off.

If LED is lit, the battery may installed incorrectly. Check polarity of battery and reinstall, if

necessary.

6Replace the compartment cover and secure with the screw.

NOTE: If controller power is restored and the battery-backed RAM has failed, field calibration of the AI

modules must be performed if greater than 0.1% accuracy is required.

WARNING

Dispose of used battery promptly.

Keep away from children. Do not disassemble and do not dispose of in fire.
