4.7.1 Connection of digital inputs
By connecting a signal voltage to the UP-2210’s digital inputs from external equipment (e.g. circuit
breaker, harmonics filter), events can be registered and recordings can be triggered as a result of
change in the digital signal.
The UP-2210 is activated on positive flanks, which means that the trig takes place when the signal
changes from a zero value to the upper limit. If you have signals with normally high values, active,
you can via the configuration in PQ Online invert the signal to trigger events when the signal drops
to zero.
4.7.2 Connection of digital outputs
By connecting the UP-2210 digital outputs to another external equipment or system, the UP-2210
can send a digital HIGH signal in the event of a disturbance (transient or sag/swell). Outputs are
activated when the meter detects a disturbance, and close the built-in relay.
