The display
unit internal clock has a slight error. When displaying the defined
time using tags or other settings, be aware of the following. At
normal operating temperatures and conditions, with the display unit
operating from its lithium battery, the degree of error is 65
seconds per month. Variations in operating conditions and battery
life can cause this error to vary from -380 to +90 seconds per
month. For systems where this degree of error will be a problem,
the user should monitor the clock and make adjustments when
required.
When the
message [RAAA051 Low
battery] appears, supply power to the display unit and fully
recharge the battery. The battery requires 24 hours of charging to
reach a level that allows backup operation, and about 96 hours (4
days) to be fully charged.
When using a GP-4100 series unit and the
Clock Update Settings is set to "Cycle", the time adjustment in
offline mode is disabled. Time data is acquired from a device/PLC
when returning to the Transfer screen.
For GP-4100 series, on exiting offline mode
do not touch [Save changes and exit]. If you touch [Save changes
and exit], offline mode ends, the display unit restarts, and time
adjustment is disabled. Time adjustment should be done separately,
after you complete display unit settings that require restarting
the display unit.
