Signal(s) updated: cyclic
The battery voltage is within the pre-warning limit range (approx. 2.7 to 2.9 V). Alarm 2100
"NCK battery warning threshold reached" has been triggered.
Refer to References for effects and measure.
The battery voltage is below the pre-warning limit range (≤ 2.6 V).
Alarm 2101 "NCK battery alarm" is signaled in cyclic operation.
Effects: A supply voltage failure - e.g. when the control is switched off - would result in the loss
of battery-buffered data (e.g. part program memory, variables,machine data ...).
Measure: Refer to additional References.
When the control ran-up, it was identified that the battery voltage was below the pre-warning
limit range (≤ 2.6 V).
Alarm 2102 "NCK battery alarm" is output; NC ready and mode group ready are not issued.
Effects: Some of the batterybuffered data may already have been lost!
Measure: Refer to additional References.
Signal(s) updated: cyclic
Basic logic functions: NC/PLC interface signals (Z1)
