(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 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, as this will not only reset the processor clock but will
also keep the time accurately during normal operation. Refer to the AADvance
Configuration Guide, Chapter 4 for the SNTP set up instructions.
Alternatively use the following procedures to set the processor clock using the
Processor Variables.
Set the Processor clock Set the Processor clock Set the Processor clock Set the Processor clock
To set the processor clock you can use the RTC variables:
1) To monitor the time wire variables to all the RTC Status points.
2)
To configure the time to be set, wire variables to the RTC Program points:
Hours
Minutes
Seconds
3)
Preset all RTC Program variables to the time that is to be programmed:
It is recommended that you set a time of 03:00. Do not set the time to
midnight or a slow clock will always be set back 24 hours.
