HARDWARE
3.4.2.2. WITH CURRENT SUPERVISION (WITH SEAL-IN)
In this case, as shown on FIGURE 3-9, the current supervision circuit consists in a circuit connected in series with the
output contact, so that the external circuit is wired to terminals 34 and 36. This supervision circuit includes a low
impedance reed relay that is activated when the current value exceeds 100 mA, and sends a signal to the main
microprocessor. This indication can be used to produce a latching of the output relay, so that it will remain closed
while the circulating current is over 100 mA. For this purpose we don't need to program any setting, it is enough to
wire it as shown on FIGURE 3-9.
With this scheme, in the case of a failure to open from the breaker auxiliary contact, the CIO output relay will not be
the one to open the tripping coil current, as in this case the contact may result damaged, as it is prepared for opening
currents around 0.5 A at 125 Vdc.
This latching or memory function is only guaranteed while the unit is powered.
