MODEL B SERIES

SINGLE CHANNEL LOOP DETECTORS

INSTALLATION AND OPERATING INSTRUCTIONS

I. General

Please verify source voltage before applying power. The model designation indicates the input power requi red, output configuration, sensitivity boost configuration, and Fail-Safe / Fail-Secure configuration for the detector as follows.

Model B-xx-xx-x Blank = Fail-Safe, S = Fail-Secure Blank = Internal DIP switches set to True Presence

DP = Internal DIP switches set to True Presence SB = Internal DIP switch set to enable Sensitivity Boost 3 or 1 = 120 VAC 4 or 5 = 12 VDC / 24 VDC / 24 VAC 8 or 35 = 240 VAC

NOTE: Models B-3, B-4 and B-8 are fitted with a rear mounted, 11-pin, Amphenol style connector. Models B-1, B-5, and B-35 are fitted with a rear mounted, 10-pin, MS style connector.

The detector is factory configured for either Fail-Safe or Fail-Secure operation (see unit side label ). The output state of each output relay in either Fail-Safe or Fail-Secure mode is listed in the table below.

II. Indicators and Controls

i. Power / Detect / Fail LEDs

The detector has one green and two red LED indicators that are used to provide an indication of the detector’s power status, output state, and/or loop failure conditions. The table below l ists the various indications and their meanings.

NOTE: If the supply voltag e drops below 7 5% of the nomina l level , the PWR LED will turn off, providing a visual indication of low supply voltage. Mode l B detectors will operate with supply vol tage as low as 70% o f nominal supply voltage.

ii. Frequency LEDs:

The four red LED indicators provide an indication of the current detector operating frequency.

iii. Front Panel Pushbutton Switches:

Two momentary contact, pushbutton switches are used to control the following. RESET - Push the front panel mounted pushbutton labeled RESET to reset the detector.

FREQ - In situations wh ere 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. The front panel mounted pushbutton labeled FREQ can be used to configure the detector to operate at one of four (4) frequencies corresponding to Low, Medium / Low, Medium / High, and High. Press the FREQ pushbutton to toggle through and select one of the four frequency settings.

NOTE: After changing the frequency setting, the detector must be reset by pressing the front panel RESET pushbutton.

Output Delay (DIP Switch 4)

A two second delay of Outputs A and B can be activated by setting DIP switch 4 to the ON position. Output delay is the time the detector outputs are delayed after a vehicl e first enters the loop detection zone. If the t wo 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 loo p detection zone during the two second delay interval, detection is aborted and the next vehicle to enter the loop detection zon e will initiate a new full two second delay interval . Th e det e cto r p rovides an indication that a vehicle is b e ing d e tected 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).

Sensitivity Boost (DIP Switch 5)

DIP switch 5 can be turned ON to increase se nsitivity during the detect pe riod without changing the sensi tivity during the no detect period. The boos t feature h as the effect of t emporarily i ncreasing the sensit ivity s etting b y 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 preventin g dropouts during the passage of high bed vehicles. The factory default setting is OFF (no Sensitivity Boost) unless sensitivity boost (SB) operation is specified, in which case the factory default setting is ON (Sensitivity Boost).

Relay B Pulse Mode (DIP Switch 6)

Relay B is the pulse output. Its pulse output mode is controlled by DIP switch 6. Relay B can be configured to output a single 250 millisecond pulse when a vehicle enters the loop detection zone (Pulse-on-Entry) or when a vehicle leaves the loop detection zone (Pulse-on-Exit). Pulse-on-Entry is selected when DIP switch 6 is OFF. Pulse-on-Exit is selected when DIP switch 6 is ON. DIP switch 6 has no effect on Relay A (the presence output). The factory default setting is OFF (Pulse-on-Entry).

NOTE: The setting of this DIP switch has no effect on the output mode of Relay B if DIP switch 8 is set to the OFF position (Presence Mode Relay B). For additional details, refer to the Relay B Output Mode section on page 3.

ON ON

Presence Hold Time (DIP Switch 7)

Output A always functions as a presence output. DIP switch 7 can be used to select one of two presence hold times; Limited Presence or True Pre s en c e the loop detection zone. True Presence Presence is selected. Limited Presence will typically hold the Call output for about one to three hours. True Presence interrupted or the detector is not reset. Tru e Presence and for normal size loops (approximately 12 ft Mode).

Relay B Output Mode (DIP Switch 8)

Relay B has two modes of operation; Pulse or Presence. Its output mode is controlled by DIP switch 8. When set to operate in Pulse Mode (DIP switch 8 ON), Relay B outputs a 250 millisecond pulse when a vehicle enters the loop detection zone or when a vehicle leaves the loop detection zone. (See the Relay B Pulse Mode section on page 2 for details.) When set to operat e in Presen ce Mode (DIP switch 8 OFF), the outpu t of Relay B is t he s ame as that of Relay A. (See the Presence Hold Time section above for details.) The factory default setting is ON (Pulse Mode Relay B) unless dual presence (DP) operation is specified, in which case the factory default setting is OFF (Presence Mode Relay B).

III. 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 l eaves the loop detection zone (loss of power or power dips of two seconds or less will not b ring a gate arm do wn onto cars as they wait at the gate).

IV. Failed Loop Diagnostics

The FAIL LED provides an indication of 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 turn off to indicate that the loop fault condition has been corrected and that the loop is once again within tolerance.

The Model B detector automatically stores the last loop failure type in non-volatile memory. To determine the type of loop failure that has last occu rred, pr ess and hold t he FREQ pushbu tton for at le ast three second s. When the FAIL LED begins flashing at one Hz rate with a 5% duty cycle, release the FREQ pushbutton. The detector will then dis play the last loop failure type detect ed (if any). This indication will be displayed one time terminated by pressing the RESET or FREQ pushbutton. The non-volati le memory used to store the last loop failu re type is automatically cleared each time it is interrogated.

VII. Warnings

Separately, for each loop, a twisted pair should be created consisting of onl y two (2) loop wires running the entire distance from the loop to the detector (incl uding 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.

VIII. Loop Installation

The vehicle detection characteristics of an inductive loop detector are greatly influenced by the lo op size an d p roximity to moving metal objects such as gates . Vehicles such as small motorcycl es and high bed trucks can be reliab ly detected if the proper size loop is selected. If the loop is placed too close to a moving metal gate, the detector may detect th e gate. The diagram below is intended as a reference for the dimensions that w ill influence the detection characteristics.

General Rules

1. The detect ion height of a loop is 2/3 the shortest leg (A or B) of the loop. Example: Short leg = 6 feet, Detection Height = 2/3 x 6 feet = 4 feet.

A = 6 ft 9 ft 12 ft 15 ft 18 ft 21 ft C = 3 ft 4 ft 4.5 ft 5 ft 5.5 ft 6 ft

2. As the length of leg A is increased, distance C must also increase.

3. For reliable detection of small motorcycles, legs A and B

A = Loop dimension parallel to the gate

B = Loop dimension perpendicular to the gate

C = Distance of the loop from the gate

SLIDE GATE

Loop Installation - Saw Cut Type

1 Mark the loop layout on the pavement. Remove sharp inside corners that can damage the loop wire insulation. 2 Set the saw to cut to a depth (typically 2" to 2.5") that ensures a minimum of 1" from the top of the wire to pavement

surface. The saw cut width should be larger than the wire diameter to avoid damage to the wire insulation when placed in the saw slot. Cut the loop and feeder slots. Remove all debris from the saw slot with compressed air. Check that the bottom of the slot is smooth.

3 It is highly recommended that a continuous length of wire be used to form the loop and feeder to the detector. Loop wire

is typically 14, 16, 18, or 20 AWG with cross-linked polyethylene insulation. Use a wood stick or roller to inse rt th e wire to the bottom of the saw slot (do not use sharp objects). Wrap the wire in the loop saw slot until the desired number of turns

is reached. Each turn of wire must lay flat on top of the previous turn. 4 The wire must be twisted together a minimum of 6 twists per foot from the end of the saw slot to the detector. 5 The wire must be held firmly in the slot with 1" pieces of backer rod every 1 to 2 feet. This prevents the wire from floating

when the loop sealant is applied. 6 Apply the sealant. The sealant selected should have good adhering properties with contraction and expansion

characteristics similar to those of the pavement material.
