Electrical connection
Power is supplied to the induction loop detector via the connecting terminal X1 of the
base.
Supply voltage 230 AC, 50 Hz.
On the output side the detector features two potential-free make contacts with the
following functions:
Relay K1: Terminal 10 and 11. Channel 1, 1st loop.
Relay K2: Terminal 7 and 8. Channel 2, 2nd loop.
Impulse without direction logic
If the detector detects a vehicle in the loop field, the relay generates an output impulse
of approx. 1.5 sec. duration.
Presence without direction logic
If the detector detects a vehicle in the loop field, the contact is activated, as long as the
vehicle is on the loop.
Impulse with direction logic
If the detector detects a vehicle in the loop field (channel 1) and then in the loop field
(channel 2), too, the relay K1 generates an output impulse of approx. 1.5 sec. durati-
on.
If the detector detects a vehicle in the loop field (channel 2) and then in the loop field
(channel 1), too, the relay K2 generates an output impulse of approx. 1.5 sec. duration.
Presence with direction logic
I the detector detects a vehicle in the loop field (channel 1) and then in the loop field
(channel 2), too, the relay K1 switches as long as the vehicle is on the loop.
If the detector detects a vehicle in the loop field (channel 2) and then in the loop field
(channel 1), too, the relay K2 switches as long as the vehicle is on the loop.
LED status display
After switching the unit on, the green LED (PWR) indicates that the detector is ready
for operation. When switched on, the red LEDs (CH1 and CH2) flash rapidly and go
out once automatic self-adjustment has taken place.
