Operating Hour Function
Operating Hour Parameters
The operating hours count the relay on time. The operating hours sums up to determine on time. The
accumulated operating hours are stored in the 2 byte counter. The counter value sends to bus
cyclically or after request. If the voltage fails or ETS programming, all operating hour counter stored
in the devices. After the bus voltage returns, the device updates communication object value.
NOTE: User changed relay position by hand; device cannot detect it so operating hour doesn’t start
the counting.
