Maintenance
Periodical maintenance
Most of the parts incorporated in the positioning unit will never need to be replaced. However,
the service life of the battery is approximately 5 years (The guaranteed period is 1 year.), and it
should be replaced periodically using the following procedure. Purchase batteries when they
are required.
The FX
2N
-10GM is batteryless, and programs and parameters are saved in built-in EEPROM.
Also check the following items when inspecting other equipment.
•
Is the temperature inside the panel abnormally high due to heat radiating bodies in the
vicinity or to direct sunlight?
•
Has any dust or conductive material entered inside the panel?
•
Are there any loose or rusted terminals, or damaged wires?
Replacement of battery
If the battery voltage is low, the BATT.V LED on the front panel is lit when the power is turned
ON. Although memory data will be retained for approximately 1 month after this LED is lit for
the first time, the battery should be replaced as soon as possible and power should be kept ON
as much as possible until it is replaced.
Note that even if an EEPROM cassette is used as the program memory, the battery is still
required to protect data saved in battery-backed memory.
Battery replacement procedure
1) Turn OFF the power of the FX
2N
-20GM.
2) Lift up the upper part of the panel cover using your fingertips or the blade of a screwdriver,
and open the cover.
3) Remove the old battery from its holder and remove the connector.
4) Insert the connector of a new battery immediately (within 30 sec. after removal of the old
battery).
5) Fit the new battery into the holder and attach the panel cover.
