|Loop Frequency: There are 4 frequencies (normally in the range of 20 to 100 kHz) that are DIP switch selectable for each
channel from the front panel. NOTE: Loops connected to channels 1 and 2 cannot crosstalk (loops are sequentially select
different frequencies for each loop to avoid loop interference.
Reset: Reset button resets both channels. Changing any dip switch position (except SW 1 & SW 2: frequency selection)
will reset the channel. After changing the Frequency selection switches, the detector will require a RESET. Reset will clear
the loop fault memory.
Sensitivity: Vehicle detection results when a negative change in loop inductance (-ΔL/L) exceeds the sensitivity setting.
Four detection sensitivity levels for each channel are front panel DIP switch selectable.
Sensitivity Boost: An external dip switch setting may be turned on to increase sensitivity during the detect period. When a
vehicle enters the loop, the detector sensitivity is boosted to a higher level than the vacant loop setting. The boosted
sensitivity remains throughout the detect period. When the vehicle leaves the loop, the sensitivity returns to the vacant
loop setting. This feature helps prevent dropouts during the passage of high bed vehicles and is particularly useful in
sliding gate situations.
Output Relay(s): The output is selectable for each channel for either "TruePresence " or "Pulse on Entry". TruePresence
will hold the call for as long as the vehicle is present and power is not removed or reset applied. The TruePresence time
applies only for normal size automobiles and trucks and for normal size loops (approx. 12 sq. ft. to 120 sq. ft.). The pulse
(width) output is 250 milliseconds.
Directional Logic (AX2DL Series): Directional Logic, also known as AB Logic or BA Logic uses the Ch. 1 & Ch. 2 loops to
determine the direction the vehicle is traveling. The loops must be spaced such that a vehicle can span both loops. The
expected installation is two loops, one after the other in the same lane, spaced anywhere from overlapping to 6 feet apart.
AB Logic is when a vehicle travels from Ch. 1 loop (A) and enters the Ch. 2 loop (B) (vehicle is now over both loops),
activating the relay and LED on Ch. 2 to indicate the AB direction. BA Logic is when a vehicle travels from Ch. 2 loop (B)
and enters the Ch. 1 loop (A), activating the relay and LED on Ch. 1 to indicate the BA direction.
Power Down Memory: When power is remove, the detector automatically "remembers" the operating parameters of the
loop for each channel. During the loss of power, vehicles may enter or leave the loop area. When power is restored, the
detector will determine if any vehicle is present in the loop and output a call if appropriate. IMPORTANT: After installing
and applying power, momentarily push the RESET button to clear the Power Down Memory. This initializes the detector to
the loops that are connected and clears the memory of any previous loop information.
Power Status Indicator: A green super-high-intensity light emitting diode (LED) indicates power status during normal
detector operation. When the green (PWR) LED is on, the power to the detector is normal. When power drops
approximately 20% from nominal, the green LED turns off and the detector remains operational. When power drops
approximately 25% from nominal, the green LED is off and the "line" voltage is not sufficient to operate the detector.
Detect Status Indicator: The red detect LED is steady on while a vehicle is being detected.
Loop FAIL Monitor Indicator: If the total inductance of the detector input network goes out of the range specified for the
detector or suddenly changes more than +/-25% the detector will enter FAIL mode. The red FAIL LED will either begin
flashing with a 50% duty cycle once per second for a shorted loop condition or will be on continuously for an open loop
condition. These indicator conditions will continue until the inductance returns to its previous value at which time the
detector output will automatically resume normal operation, and the red FAIL LED will flash at a distinctive rate (a burst of
3 flashes once per second) to indicate an intermittent loop fault has occurred and corrected. The flash rate will continue
until another loop fault occurs, the detector is RESET, or the detector loses power. [The detector input network, consists
of the loop or loops plus the feeder cable (lead-in or home run) up to the connector on the detector].
Fail Safe Operation: When either Ch. 1 or Ch. 2 loop fails or power is removed, continuity exists between that channel's
Common & N.O..
Fail Secure Operation: When either Ch. 1 or Ch. 2 loop fails or power is removed, continuity exists between that channel's
Common & N.C.
Self Tuning: Automatically tunes to loop within 2 seconds after application of power or reset. 30 seconds of operation is
required before full sensitivity and presence time is reached following application of power or a reset.
Environmental Tracking: Fully self-compensating for environmental changes and loop drift over the full temperature range
and the entire loop inductance range.
Loop Inductance Range: 20 to 1000 µh with Q factor of 5 or greater.
Loop Input: Transformer isolated. The minimum capacitance added by the detector is 0.068 mF.
Grounded Loop Operation: The loop isolation transformer allows operation with poor quality loops (which may include a
single point short, or leakage, to ground).
Lightning Protection: The detector can tolerate, without damage, a 10 mF capacitor charged to 1,000 Volts being
discharged directly into the loop input terminals, or a 10 mF capacitor charged to 2,000 Volts being charged between
either loop terminal and earth ground.
Internal Circuitry Isolation: All internal electronic circuitry is isolated from all external circuitry. Power is isolated by
means of the power transformer. The loop is isolated by means of the loop isolation transformer. The outputs are isolated
by means of the output relays.
Automatic Reset Internal Fuse: When 120VAC is applied to 24VAC models, the automatic internal fuse will open. The fuse
will automatically reset when power is removed for 3 seconds. Source voltage should be verified before reinstalling.
Relay Rating(s): The relay contacts are rated for 2 Amp max, 60 VDC max, 120 VAC max and 30 Watts max switched
Ruggedized Construction: The enclosure is high temperature rated Lexan plastic. Printed circuit boards are double sided
2-oz copper with plated through-holes.
