DIP SWITCH 1 to 6
For explanation of functions set by DIP switch 1 to 6, see description for Single Loop Detector (LDD1).
DIP SWITCH 7 - Output mode for relay 1
This setting determines how relay 1 should indicate a vehicle detection in the loop. The Loop Detector
can generate a single pulse each time a vehicle enters or leaves the loop (Pulse mode). Alternatively
the output can be kept activated as long as there is a vehicle present inside the loop (Presence mode).
• When DIP SWITCH 7 is set to ON relay 1 operates in Presence mode and output is activate as long
as a vehicle is present inside the loop.
• When DIP SWITCH 7 is set to OFF relay 1 operates in Pulse mode and generates a pulse each time
a vehicle enters or leaves the loop.
Note: DIP switch 8 will have different functionality depending if product is set to operate in pulse
or presence mode on DIP switch 7.
DIP SWITCH 8 - Mode select for relay 1 (only for Pulse mode)
When the Loop Detector is operating in Pulse mode (see DIP switch 7), the output pulse can be
generated either when a vehicle enters the loop or when a vehicle exits the loop. This is selected by
DIP switch 8.
• When DIP SWITCH 8 is set to ON, relay 1 creates a pulse each time a vehicle exits the loop.
• When DIP SWITCH 8 is set to OFF, relay 1 creates a pulse each time a vehicle enters the loop.
DIP SWITCH 8 - Timeout setting for relay 1 (only for Presence mode)
When relay 1 is operating in Presence mode (see DIP switch 7), a timeout can be set to limit maximum
activation time of a single vehicle detection. If timeout is set different from infinite, the output will
automatically deactivate, if a vehicle has been constantly detected for longer time than set by DIP
switch 8.
• When DIP SWITCH 8 is set to ON relay 1 timeout is set to 1 minute.
• When DIP SWITCH 8 is set to OFF relay 1 timeout is set to infinite.
DIP SWITCH 9 - Output mode for relay 2
This setting determines how relay 2 should indicate a vehicle detection in the loop. The Loop Detector
can generate a single pulse each time a vehicle enters or leaves the loop (Pulse mode). Alternatively
the output can be keept activate as long as there is a vehicle present inside the loop (Presence mode).
• When DIP SWITCH 9 is set to ON relay 2 operates in Presence mode and output is activate as long
as a vehicle is present inside the loop.
• When DIP SWITCH 9 is set to OFF relay 2 operates in Pulse mode and generates a pulse each time
a vehicle enters or leaves the loop.
Note: DIP switch 10 will have different functionality depending if product is set to operate in Pulse
or Presence mode on DIP switch 9.
DIP SWITCH 10 - Mode Select for relay 2 (only for Pulse mode)
When the Loop Detector is operating in Pulse mode (see DIP switch 9), the output pulse can be
generated either when a vehicle enters the loop or when a vehicle exits the loop. This is selected with
DIP switch 10.
