Functional description:
MICO 4.6 is a 4-channel electronic auxiliary circuit
switch and serves as current monitoring. The
operating voltage (+24V DC / at least 10A) is divided
into 4 current monitored load circuits (channels). By
applying the operating voltage the switched-on
channels are time-delay activated (time-delay of each
channel = 75 ms) to avoid overload current. The
current selector switches (1) enable an independent
setting of the operating currents of 1A, 2A, 4A or 6A
(see disconnecting characteristic). When exceeding
the 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 reestablished after the recovery of the supply
voltage. The setting of the current range during
operation leads to the disconnection of the channel. It
may only be switched on manually. Each channel may be manually connected or disconnected through the buttons (2).
The current operating condition is signalled by the LED (2) – (red/green, see displays). All channels disconnected due
to overload may be activated through ON (restart) (3) – see restart. In addition, the module is provided with a
potential-free message output (4) to establish a summation message (see control output). A bridging concept permits
the lining-up of multiple modules (maximum operating current 40A) without wiring. For this purpose a bridging set is
available as an option.
