5.6 RESTART
FOR SG-RB...-W MODELS
The Restart mode and Reset/Restart wire must be connected through a N.C. button to the 0V or 24V from
the power supply of the ESPE to select, respectively, manual restart or automatic restart.
The Reset/Restart wire can be used to enter alignment function when N.C. button is pressed at start-up.
The RESET/RESTART button must be located in such a way that the operator can check the
protected area during any reset operation (see section 3).
5.7 EXTERNAL RELAYS CONNECTION
Example: connection to the safety relay.
The previous figure shows the connection between the safety light curtains and the safety relay of the SE-
SR2 series functioning in the Automatic Restart mode (left side) and Manual Restart with monitoring (right
side).
•
Do not use varistors, RC circuits or LEDs in parallel at relay inputs or in series at OSSD
outputs.
•
The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but
must be used separately (Figure 30), conforming to the plant's safety requirements.
•
If one of these configurations is erroneously used, the device enters the output failure
condition.
