Connection Of The Sensor (In1); Input Reset - IFM Electronic ecomot200 DW2003 Notice D'utilisation

FA-1
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 electrically separated
from other circuits).
If the unit is AC supplied (DW2003), the low voltage provided for the sensor sup-
ply 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.
The terminals 5/6 can be used to supply the pick-ups with voltage or to trigger the
reset input.
Input reset 1 (external reset)
A pulse (+24 V DC) on terminal 11 resets the relay state latched in case of a fault
if the latching function is active (parameter SO2). If the signal is no longer provid-
ed, the set start-up delay (ST2) starts.
Pressing the pushbuttons continuously does not influence the monitoring function.
