Wiring diagram:
Functional description:
MICO BASIC 4.2 is a 4-channel electronic auxiliary circuit switch and serves as current monitoring. The
operating voltage (+24V DC / at least 10A) supplies the 4 current monitored load circuits (channels). By
engaging the operating voltage, the switched-on channels are time-delay activated (time-delay of each channel
ca. 75 ms) to avoid overload current. When exceeding the permitted operating current, the corresponding
channel will be disconnected pursuant to the disconnecting characteristic. In the event of voltage dip or power
failure the current operating condition will be saved and re-established after the recovery of the supply voltage.
Each channel may be manually connected or disconnected through the buttons
condition is signalised by the LED
(2)
(red/green, see displays). All channels disconnected due to overload
(3)
may be activated through ON-Restart
(see ON-Restart - input). In addition, the module is provided with a
message output
(4)
to establish a summation message (see summation message). A bridging concept permits
the lining-up onto a MICO CLASSIC (e.g. 4.4 / 4.6 / 4.10) without wiring (max. total operating current: 50A). For
this purpose a bridging set is available as an option.
Bridging set:
The bridging set minimises the efforts of wiring, if multiple modules need to be joined together. It offers the
possibility of bridging the following potentials: +24 V DC
with the in the bridging enclosed connecting piece
