Functional description:
MICO 2.10 is a 2-channel electronic auxiliary circuit switch and serves as current monitoring. The operating
voltage (+24V DC/at least 20A) is split into 2 current monitored load circuits (channels). When engaging 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
currents of 4A, 6A, 8A or 10A (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 signalised by the LED
displays). All channels disconnected due to overload may be activated through ON (restart)
In addition, the module is provided with a potential-free message output
message (see summation message). A bridging concept permits the lining-up on a 4-channel MICO module
(maximum operating current 40A) without the installation of a cable system. For this purpose a bridging set is
available as an option (see bridging set).
Bridging set:
The bridging set minimises the efforts of wiring if multiple modules are joined together.
It offers the possibility of bridging the following potentials:
+24V DC

, GND
(8)
, ON
(6)
and summary message
modules
(9)
. The bridging set is optionally available under:
