Connection Of The Sensors (In1, 2) - IFM Electronic ecomat200 FD-2 Notice D'utilisation

FD-2
MONITOR
The device shall be supplied from an isolating source and protected by an overcur-
rent protection device such that the limited voltage circuit requirements in accor-
dance with UL 508 are met.
If the DC circuit is to be grounded (e.g. due to national regulations), the respective
directives must be adhered to (safe extra-low voltage, circuit galvanically separated
from other circuits).
If the unit is AC supplied, the low voltage provided for the sensor supply meets
the SELV criteria according to EN 61010, overvoltage category II, soiling degree 2.
To guarantee safe functioning, signal cables (sensors, transistor outputs, 24 V digi-
tal inputs) and load cables (supply, relay outputs) should be laid separately. If nec-
essary, use a screened cable.

The connection of mechanical switch contacts is not recommended since they tend
to bounce and produce faulty pulses.
Input reset 1/2 (external reset and release of the start-up delay)
If the start-up delay or latching reset is to be started externally, this can be done
using a 24 V DC signal at terminal 17 or 18.
Terminal 17 = reset/release for output 1
Terminal 18 = reset/release for output 2
To trigger the reset inputs the 24 V DC voltage at terminal 5 can be used via a
closing contact. The negative reference point of this voltage must be terminal 1 of
the monitor.
