Description of the different modes
Automatic mode
In the automatic mode, the barrier is automatically
reset at power up or after any intrusion in the
detection field
. There’s no need for pressing a push-
button for reseting the system and closing contacts
B1-B2 and C1-C2. There is no need to open the
receiver unit in this mode except if the FSD monitoring
is required (see § 8.6).
Start interlock mode
In the start interlock mode, it is necessary to press
a push-button to reset the system and close
contacts B1-B2 and C1-C2 at power up only
.
Normally closed contact of this push-button must be
connected between terminals C3 and C5. The receiver
unit must be opened to change the jumper links
position (refer to § 8.6).
Start and Restart interlock mode
In that mode, pushing a button is necessary at
power up or after any intrusion in the detection
field to reset the system and close contacts B1-
B2 and C1-C2
. Normally open contacts of this push-
button must be connected between terminals C3 and
C5. The receiver unit must be opened to change the
jumper links position (refer to § 8.6).
Selection of a restart mode
The selection of one of these modes is done with the
jumper links position (refer to § 8.6).
Automatic mode
The device is delivered in this mode. If the FSD
monitoring is required then the jumper links position
must be changed (refer to § 8.6).
