Frequency (DIP Switches 1 and 2):

In situations where loop geometry forces loops to be located in close proximity to one another, it may be
necessary to select different frequencies for each loop to avoid loop interference, commonly known as
crosstalk. DIP switches 1 and 2 can be used to configure the detector to operate at one of four frequencies
corresponding to Low, Medium / Low, Medium / High, and High as shown in the table below.

NOTE: After changing any frequency switch setting(s), the detector must be reset by momentarily
changing one of the other switch positions.

Presence Hold Time (DIP Switch 3):

Output A always functions as a presence output. DIP switch 3 can be used to select one of two presence
hold times; Limited Presence or True Presence

. Both modes provide a Call output when a vehicle is

present in the loop detection zone. True Presence

is selected when DIP switch 3 is OFF. If DIP

switch 3 is ON, Limited Presence is selected. Limited Presence will typically hold the Call output for
about one to three hours. True Presence

will hold the Call as long as the vehicle is present in the loop

detection zone provided that power is not interrupted or the detector is not reset. TruePresence

time

applies only for normal size automobiles and trucks and for normal size loops (approximately 12 ft

to 120

). The factory default setting is OFF (True Presence

Mode).

Sensitivity Boost (DIP Switch 4):

DIP switch 4 can be turned ON to increase sensitivity during the detect period without changing the
sensitivity during the no detect period. The boost feature has the effect of temporarily increasing the
sensitivity setting by up to two levels. When a vehicle enters the loop detection zone, the detector
automatically boosts the sensitivity level. As soon as no vehicle is detected, the detector immediately
returns to the original sensitivity level. This feature is particularly useful in preventing dropouts during the
passage of high bed vehicles. The factory default setting is OFF (no Sensitivity Boost).

Output Delay (DIP Switch 5):

A two second delay of Outputs A and B can be activated by setting DIP switch 5 to the ON position.
Output delay is the time the detector outputs are delayed after a vehicle first enters the loop detection zone.
If the two second Output Delay feature is activated, the output relays will only be turned on after two
seconds have passed with a vehicle continuously present in the loop detection zone. If the vehicle leaves
the loop detection zone during the two second delay interval, detection is aborted and the next vehicle to
enter the loop detection zone will initiate a new full two second delay interval. The detector provides an
indication that a vehicle is being detected but that the outputs are being delayed, by flashing the front panel
DET LED at a four Hz rate with a 50% duty cycle. The factory default setting is OFF (no Output Delay).

Relay B Fault Output (DIP Switch 6):

When DIP switch 6 is in the ON position, Output B will operate in Fault mode. When operating in Fault
mode, Relay B will provide a fault indication only when a loop fault condition exists. If a loss of power
occurs, Relay B will operate as a Fail-Secure output. If the loop fault condition self-corrects, Relay B will
resume operation in the No Fault output state. The factory default setting is OFF (Relay B Presence or
Pulse).

NOTE: Setting this switch to the ON position overrides the settings of DIP switches 7 and 8.

Relay B Output Mode (DIP Switches 7 and 8):

Relay B has four (4) modes of operation: Pulse-on-Entry, Pulse-on-Exit, Presence, and Fault. Fault mode
is selected with DIP switch 6. (See the Relay B Fault Output section on page 2 for details.) DIP
switches 7 and 8 are used to configure the Presence and/or Pulse output modes of Relay B.

When set to operate in Pulse mode (DIP switch 8 set to OFF), Relay B can be set to provide a 250
millisecond pulse when a vehicle enters or exits the loop detection zone. DIP switch 7 is used to select
Pulse-on-Entry or Pulse-on-Exit. When DIP switch 7 is OFF, Pulse-on-Entry is selected. When DIP
switch 7 is ON, Pulse-on-Exit is selected.

When set to operate in Presence mode (DIP switch 8 set to ON), Output B presence hold time is the same
as Output A.

The table below shows the various combinations of switch settings and Relay B modes of operation.

III. Reset:

Changing any DIP switch position (except 1 or 2) or the Sensitivity level setting will reset the detector. After
changing the frequency selection switches, the detector must be reset.

IV. Call

Memory:

When power is removed for two seconds or less, the detector automatically remembers if a vehicle was present
and a Call was in effect. When power is restored, the detector will continue to output a Call until the vehicle
leaves the loop detection zone (loss of power or power dips of two seconds or less will not bring a gate arm
down onto cars as they wait at the gate).

Failed Loop Diagnostics:

The FAIL LED indicates whether or not the loop is currently within tolerance. If the loop is out of tolerance,
the FAIL LED indicates whether the loop is shorted (one Hz flash rate) or open (steady ON). If and when the
loop returns to within tolerance, the FAIL LED will flash at a three flashes per second rate to indicate that an
intermittent loop fault has occurred and has been corrected. This flash rate will continue until another loop fault
occurs, the detector is reset, or power to the detector is interrupted.

VII. Warnings:

Separately, for each loop, a twisted pair should be created consisting of only two (2) loop wires running the
entire distance from the loop to the detector (including runs through all wiring harnesses) at a minimum of six
(6) complete twists per foot. For trouble free operation, it is highly recommended that all connections
(including crimped connectors) be soldered.
