Functions

4.4 On Delay

As soon as a minimum input voltage is present, the channel is activated with a time de-
lay. This requires the channel to be switched on before the input voltage is switched off.
Note
Note the behavior when the input voltage is restored!
The circuit breaker channel switches to the status it had before the input voltage was
switched off. A channel that was manually switched off tripped is not automatically
switched on.
The channel is randomly activated within 0 ... 500 ms with a time delay. If multiple elec-
tronic circuit breakers are connected to one power supply, this avoids larger current
spikes at switch-on.

4.5 Control Input S1 and Signal Output S2

Control Input S1
A signal (15 ... 30 V) between the control input and GND allows the status of the elec-
tronic circuit breaker to be changed. Which status is produced depends on the signal du-
ration and previous status of the ECB.
Signal
Signal 1:
Reset channel.
Signal 2:
Switch channel on.
Signal 3:
Switch channel off.
For more detailed information on individual signals and statuses, see the "General Oper-
ating Statuses" diagram in
Signal Output S2
The channel status can be queried at the signal output. The signal output is short-circuit-
proof and has a common potential with the power supply ground. The High signal output
is not tripped.
The signal output can be configured in the default settings.
If the product has tripped, the signal output indicates this with a low signal (0 V). The sig-
nal outputs of up to 10 devices can be connected in parallel and serve as a common sig-
nal.
