The currents are detected and evaluated as true r.m.s. values in the frequency range of 0 (42)…2000 Hz. All channels are scanned simultaneously so that the maximum scanning time for all channels is 180 ms if 1x the response value is exceeded and 30 ms if 5x the response value is exceeded.The current values of all channels are indicated on the LC display in bar graph format. If one of both values falls below or exceeds the set response value, the response delay ton begins. Once the response delay has expired, the common alarm relays “K1/K2” switch and the alarm LEDs 1/2 light up.Two response values/common alarm relays, which can be set separately, allow a distinction to be made between prewarning and alarm. The faulty channel(s) and the associated measured value are indicated on the LC display. If the current exceeds or falls below the release value (response value plus hysteresis), the delay on release toff begins. Once the delay has expired, the common alarm relays return to their initial position.
