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 offline mode.
When using GP-4100 series, the adjusted time will be disabled if the unit is rebooted after exiting offline mode.
