BATTERY & TIME KEEPING
A battery is used to keep time when the unit is without power. Typical
accuracy of the G303 time keeping is less than one minute per month drift. The
battery of a G303 unit has no affect on the unit’s memory as all configurations
and data are stored in non-volatile memory.
CAUTION: The circuit board contains static sensitive
components. Before handling the operator interface without the
rear cover attached, discharge static charges from your body by
touching a grounded bare metal object. Ideally, handle the
operator interface at a static controlled clean workstation. Also,
do not touch the surface areas of the circuit board. Dirt, oil, or
other contaminants may adversely affect circuit operation.
To change the battery of a G303, remove power, cabling, and then the rear
cover of the unit. To remove the cover, remove the four screws designated by
the arrows on the rear of the unit. Then, by lifting the top side, hinge the cover,
thus providing clearance for the connectors on the bottom side of the PCB as
shown in the illustration below. Install in the reverse manner.
Remove the old battery* from the holder and replace with the new battery.
Replace the rear cover, cables, and re-apply power. Using Crimson or the unit’s
keypad, enter the correct time and date.
* Please note that the old battery must be disposed of in a manner that
complies with your local waste regulations. Also, the battery must not be
disposed of in fire, or in a manner whereby it may be damaged and its contents
come into contact with human skin.
The battery used by the G303 is a lithium type CR2025.
