Note: The processor back up battery is supplied separately and must be installed into each new
processor.
To install a new battery, do the following:
(Part No: T9905 Poly-carbonmonofluride Lithium Coin Battery, BR2032 (recommended type) ,
20mm dia; Nominal voltage 3V; Nominal capacity (mAh) 190; Continuous standard load (mA) 0.03;
Operating temperature -30°C to 80°C, supplied by Panasonic. The battery will last for approximately
10 years under normal operating conditions, or approximately six months if the module is not in use.
1) Use a small cross head screwdriver to release the battery cover. Remove the
cover.
2) To remove an old battery pull on the ribbon in the battery holder and pull the
battery out.
3) To install a new battery orientate the new battery with the positive (+) terminal to
the right. Trap the ribbon behind the new battery so it can be removed in the
future and then push the battery into the holder.
4) Reinstall the battery cover.
5) Press the Fault Reset button on the processor module. The processor Healthy
LED will go green (applies if the module is part of a running system).
If the battery is replaced when only a single processor module is installed and the processor module is
not under power the processor clock will need to be be reset to the current time. Correct the clock
at the earliest opportunity. If it is replaced when more than one processor module is installed then the
clock will be updated through synchronization.
If you have previously set up SNTP when you set up your processor module then the clock will be
reset to the current time automatically. If you haven't set up SNTP it is recommended that you do so,
