Installation instructions
Wiring diagram:
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 split into 4 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 (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 signalised 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 summation message). 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 (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 (7), GND (8), ON (6) and summary message (5). A connecting piece is necessary to anchor both
modules (9). The bridging set is optionally available under:
item no.: 9000-41034-0000001 (packing unit 10 pieces)
item no.: 9000-41034-0000002 (packing unit 1 pieces)
