1 INFORMATION ON THIS DOCUMENT
1.1 Function
The present instruction sheet provides information on installation, connection and safe use of the
ST series safety sensor with RFID technology for safe control of protections and guards, according
to EN ISO 14119.
1.2 Addressed to: qualified personnel only
The operations of the present instruction sheet must exclusively be carried out by qualified
personnel which is perfectly able to understand them and has been duly authorised.
1.3 Application field
These instructions apply exclusively to the ST series and to its accessories.
2 SYMBOLS USED
This symbol indicates any relevant additional information.
Attention: Any failure to observe this warning note can cause damage or malfunction,
including possible loss of the safety function.
3 FITTING INSTRUCTIONS
3.1 Actuation and fixing directions
The centring symbols
on the sensor and actuator must be facing each other.
3.2 Fixing the sensor and the actuator
Attention: The sensor and the actuator must be fixed
to the machine by means of four M4 screws with a
length of 18 mm or more. The device and the actuator
must never be fixed with less than four screws.
Tightening torque of the four M4 screws from 0.8 to 2
Nm
Attention: As required by EN ISO 14119, the
actuator must be fixed immovably to the door
frame.
Pan head safety screws with one-way fitting are
available for this purpose, article: VF VAM4X**BW-X.
After fixing, you must plug the screw holes with the
caps supplied, in order to make them less accessible.
For correct fixing, other means can also be used, such as rivets, non-removable security
screws or other equivalent fixing system.
3.3 Assembly of multiple sensor-actuator systems
50
The minimum spacing between adjacent sensor-
actuator systems must be at least 50 mm, in all
directions.

3.5 Actuation distances
When the actuator is brought inside the safe activation zone (dark grey area), the sensor enables
the safety outputs (OUT LED on, green).
When the actuator leaves the safe zone, the sensor keeps the safety outputs enabled and, by
means of the LED ACT (blinking, orange), it indicates that the actuator is entering the limit activation
zone (light grey area).
When the actuator leaves the limit activation zone, the sensor disables the outputs and switches
off the LED OUT.
Attention: The device actuation/release distances can be influenced by the presence of
conductive or magnetic material in the sensor vicinity. The working actuation and release
distances must always be checked following installation.

4 OPERATION
4.1 Definitions
States of the sensor:
•
OFF: sensor off, not powered.
•
POWER ON: state immediately following switch on, during which the sensor carries out internal
tests.
•
RUN: state in which the sensor is in normal operation.
•
ERROR: safety state in which the outputs are disabled. Indicates presence of a failure, either
internal or external to the device, such as for example:
- a short circuit between the safety outputs (OS1, OS2)
- a short circuit between a safety output and ground, or
- a short circuit between a safety output and the supply voltage
To exit this state, the sensor must be restarted.
The EDM External Device Monitoring function (where present) is a function which allows the device
to monitor the state of external contactors. Activation and deactivation of external contactors must
follow the ST sensor safety outputs within a predefined time period (see paragraph 4.4).
