Connection of the alarm output
The alarm output of the 362MC is provided as a
changeover contact. The alarm relay is operated
according to the closed-circuit principle. When the
controller is functioning correctly, the relay coil is
energised. In the event of an error or power failure,
the coil voltage will be cut.
The alarm contact drops into its normal condition, as
illustrated on the symbol printed on the backside.
9.5
Connection of the binary inputs
The 362MC possesses 6 binary inputs, which can
be used for various functions and can be assigned
to functions as required via the parameters in the
Input menu.
In standard configuration, the inputs are to be
connected as
floating
contacts. The contact voltage
is provided by the controller.
As a special variant, the 362MC can be supplied
with an input circuit for
DC
contacts for a nominal
voltage of 24V DC. These inputs are to be
connected to
+24V
and the reference potential
0V
is to be connected to terminal 20.
9.6
Connection of the resistor feedback sensor
The remote resistor feedback sensor is connected to
the 362MC at the 4
th
analogue input, using a two-core
cable.
After mechanical adjustment of the sensor on the actuator,
calibration is carried out via parameter entry in the Input
menu.

Connection of a U/I measured-value transmitter
In the standard configuration of the 362MC, the
3
rd
analogue input serves as a current input for currents
from 0-20mA or 4-20mA. The current input is configured
as a differential amplifier input. The max. common-mode
voltage is +2V.
The 362MC is also available in a special version with a
voltage input for 0-10V or 0-5V. The appropriate hardware
configuration is to be observed here.
