DIP SWITCH 10 - 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 10 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 10 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 11 and 12 will have different functionality depending if product is set to operate
in Pulse or Presence mode on DIP switch 10.
DIP SWITCH 11 - Time setting for relay 2 (only for Pulse mode)
When the Loop Detector is operated in Pulse mode (see DIP switch 10), the pulse length can be
changed with DIP switch 11.
• When DIP SWITCH 11 is set to ON relay 2 creates a pulse with a duration of 0.5 s for each
activation.
• When DIP SWITCH 11 is set to OFF relay 2 creates a pulse with a duration of 0.1 s for each
activation.
DIP SWITCH 12 - Entry or Exit mode for relay 2 (only for Pulse mode)
When the Loop Detector is operated in Pulse mode (see DIP switch 10), 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 12.
• When DIP SWITCH 12 is set to ON relay 2 creates a pulse each time a vehicle exits the loop.
• When DIP SWITCH 12 is set to OFF relay 2 creates a pulse each time a vehicle enters the loop.
DIP SWITCH 11 & 12 - Timeout setting for relay 2 (only for Presence mode)
When relay 2 is operated in Presence mode (see DIP switch 10), 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 11 and 12.
