tAlarm and tWarning are possible to be defined with a resolution of 10 ms,
depending on the level of the defined values for the parameters.
The limit for the overflow supervision is fixed at 999999.9 seconds. The outputs
freeze if an overflow occurs.

Operation accuracy

The accuracy of TEIGAPC depends on essentially three factors
• function cycle time
• the pulse length
• the number of pulses, that is, the number of rising and falling flank pairs
In principle, a shorter function cycle time, longer integrated time length or more
pulses may lead to reduced accuracy.
Memory storage
The value of the integrated elapsed time is retained in a non-volatile memory.
