For certain specific applications, as an
alternative to connection to safety mod-
ules, it is possible to use the ST G•51•••
article with check of the NC contacts of
the forcibly guided relays (K1, K2) con-
nected to the EDM input, installed as
the last sensor in the cascade.

Articles ST G•5•••• must be connected
to contactors with forcibly guided output
contacts, as shown in the adjacent
diagram. When connected in this way,
the sensor can be classified as a control
circuit device up to PDF-M (EN 60947-
5-3)
Caution: if all OS safety outputs
are connected directly to a safety contac-
tor, we recommend using fast switching
diodes connected in parallel to the con-
tactor coils.

5.8 Operating states
The sensor has a multicolour signalling LED, which, through
the use of illumination, flashing, and colour sequences, indi-
cates the various device operating states to the user, as well
as any warnings or errors affecting internal electronic compo-
nents.
The LED can be seen on both sides of the sensor, regardless
of device installation direction.
The predefined sensor operating states (OFF, RUN, ERROR, SET) are indicated by
a constantly lit LED.
LED illumination sequence
Sensor
state
Description
OFF
Sensor off.
GN
RUN
Normal operating state with safety outputs on. No
pending error or warning.
YE
RUN
Normal operating state with safety outputs off. No
pending error or warning.
VT
SET
New actuator acquisition state.
RD
ERROR
Internal device error state.
Table 1: Predefined operating states
If an ERROR event is identified, the LED cycles between continuous light corresponding
to the ERROR state (see Table 1) with one of the illumination sequences listed in Table
2, each of which corresponds to a different message type.

If a WARNING event is identified, the LED cycles between continuous light
corresponding to the current operating state (see Table 1) with the corresponding
illumination sequence listed in Table 3.

Table 3: WARNING messages
Legend: GN = green RD = red YE = yellow
BU = blue VT = purple
WARNING events are generally reversible. ERROR events are not reversible:
the device does not recover from the error, but must be switched off, and the cause of
the error resolved prior to switching back on.
If multiple ERROR or WARNING events are present at the same time, the highest
priority error only is indicated. For example, where both a temperature warning and a
voltage warning are present, only the temperature signalling sequence is indicated;
the voltage warning sequence is indicated only once the temperature warning is no
longer active, i.e. the temperature exits the alert threshold.
5.9 Reset input
The following error states due to a failure external to the device can be rest using the
I3 input:
- a short circuit or overload of safety outputs (OS1, OS2),
- a short circuit between a safety output and the supply voltage.
