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.
The terminals 5/6 can be used for the supply of the pulse pick-up or control of the
release/reset inputs (only FS-3).
Input release 1/2 (external release of the start-up delay)
A signal (+24 V DC) on terminal 17 keeps the outputs 1 and 2 in the same state as
with the active start-up delay. If the signal is no longer provided, the set start-up
delay STP starts (min. 0.1 s). In case of a stored fault the signal on terminal 17 is
only effective after a reset has been made.
