BATTERY & TIME KEEPING
A battery is used to keep time when the unit is without power. Typical
accuracy of the G306Atime keeping is less than one minute per month drift. The
battery of a G306Aunit does not affect the unit’s memory, all configurations and
data is stored in non-volatile memory.
To change the battery of a G306A, 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 G306A is a lithium type CR2025.
CAUTION: RISK OF ELECTRIC SHOCK
The inverter board, attached to the mounting plate, supplies
the high voltage to operate the backlight. Touching the
inverter board may result in injury to personnel.
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.
WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT
EQUIPMENT UNLESS POWER HAS BEEN DISCONNECTED
AND THE AREA IS KNOWN TO BE NON-HAZARDOUS.
WARNING - EXPLOSION HAZARD - THE AREA MUST BE
KNOWN TO BE NON-HAZARDOUS BEFORE SERVICING/
