In case of loss of auxiliary power when the trip lockout function is in use, the

contacts of PO3 return to the same state as before the loss, provided that the battery

has been inserted and is charged. If no battery has been inserted, the trip lockout

function is activated and the contacts of PO3 remain open when the auxiliary power

is switched on again.

5.1.7. Trip counters for circuit-breaker condition monitoring

The trip counters for circuit-breaker condition monitoring provide history data,

which can be used for circuit-breaker service scheduling. With this information, the

service cycle can be estimated for the future.

The monitoring function consists of four counters, which count the number of trip

signals generated to the circuit breaker by the relay. Every time a stage generates a

trip signal, the corresponding counter value is increased by one. The number of trips

is stored in the non-volatile EEPROM memory.

There are separate counters for the different protection stages. The overvoltage

stages (U>, U>> and U2>), undervoltage stages (U<, U<

overvoltage stages (U0> and U0>>) have a common trip counter each, whereas there

is an own trip counter for the external trip.

The counters can be read via the HMI or SPA parameters V9...V12 and cleared via

SPA parameter V166. When a counter reaches its maximum value, it rolls over.
