Features
& Benefits
- Compatible
with all radio control and remote openers.
- Features
latest state-of-the-art surface mount technology.
- Sensitivity
Boost, selectable by setting an internal DIP switch, eliminates
possible detector dropout during passage of high bed vehicles
— this feature is particularly useful in sliding gate situations.
- External
rotary switch for 10 selectable sensitivity levels.
- Two color,
high intensity LED status indicator for Detect, Power, and Loop
Fault indication.
- Self-tuning
& complete environmental tracking.
- No warm-up
required.
- Continuous
Winky-Blink™ loop monitor which remembers and indicates intermittent
and failed loops - a great troubleshooting aid.
- If intermittent
or failed loops self-heal, the detector will resume normal operation
without manually resetting the detector.
- Three front
panel selectable loop frequencies permit complete elimination
of crosstalk.
- Large loop
inductance range: 20 to 2000 microhenries, allowing operation
with a wide range of loops.
- 10 pin MS
connector mounted on the front panel.
- Failsafe
or failsecure models available.
- Two separate
output relays:
- Output
A is presence output
- Output
B, programmable with internal DIP switches, provides presence,
pulse on entry, pulse on exit, or fail output
- An infinite
presence mode is available by setting an internal DIP switch.
- Both outputs
can be delayed for 2 seconds, by setting an internal DIP switch,
causing the detector to ignore vehicles passing over the loop
faster than about 5 miles per hour.
- Both outputs
can be extended for 0 seconds, 2 seconds, 5 seconds, or 10 seconds,
programmable with internal DIP switches.
- Detector
will not retune if power is lost for approximately 3 seconds and
then restored. Prevents vehicle detection from being lost during
brief power interruptions.
- Front panel
mounted reset switch.
- Versions
available for use with: 120 VAC and 240 VAC.

Specifications
Self-Tuning:
Automatically tunes itself and is fully operational within 1
second after application of power or after being reset. 30 seconds
is required before full presence time is possible.
Environmental
Tracking: Completely automatic over the entire loop
inductance range.
Loop
Inductance Range: 20 to 2000 microhenries with Q factor
of 5 or greater [includes loop(s) plus feeder (lead-in or home
run) cable up to the connector on the detector].
Loop
Feeder Length: Up to 2,500 feet (762 m) maximum with
proper feeder cable and appropriate loops.
Loop
Input: Transformer isolated.
Loop
Frequency: Three switch selectable frequencies (normally
in the range of 20 to 80 kilohertz). Note: Changing loop frequency
switches may make Winky-Blink™ signal appear. Reset detector
manually.
Reset:
The detector can be manually reset by the front panel switch.
The detector is reset automatically whenever the power is turned
on.
Grounded
Loop Operation: The loop isolation transformer allows
operation with poor quality loops (including a single point
short to ground).
Lightning
Protection: Loop input fully protected per NEMA specifications.
Faulty/Intermittent
Loop Monitor: If the total loop input network inductance
goes out of the range specified or suddenly changes more than
25%, both outputs immediately generate a continuous detect output
in failsafe detector versions or no detect in failsecure detector
versions and the LED begins displaying the Winky-Blink™ mode.
This condition continues until the inductance returns to its
previous value, at which time the detector outputs automatically
resume normal operation. However, the LED will continue in the
Winky-Blink™ mode until the detector is reset. See Reset.
Sensitivity:
Vehicle detection results from a sufficient change in loop inductance
(-delta L/L). 10 switch selectable sensitivity levels are shown
here (under construction.)
Sensitivity
Boost: Switch selectable, this option increases sensitivity
only during the detect period but does not affect the sensitivity
level of a vacant loop. When a vehicle enters the loop, the
sensitivity is boosted two levels and remains boosted throughout
the detect period. When the vehicle leaves the loop, the sensitivity
returns to the vacant loop level.
Output
A: Set for presence mode of operation only.
Output
B: May be switched for either presence, pulse, or
fail mode of operation with a switch. In pulse mode, the pulse
occurs on either entry or exit, as set by another switch. The
pulse duration is 250 milliseconds. In fail mode, an output
occurs whenever a loop fault occurs.
Call
Delay Option: Switch selectable, this option delays
both outputs for 0 or 2 seconds. When set to 2 seconds, the
detector will ignore cars passing over the loop faster than
about 5 miles per hour.
Call
Extend Option: Switch selectable, this option extends
both outputs for 0 seconds, 2 seconds, 5 seconds, or 10 seconds.
Presence
Modes: Switch selectable. Applies to output B when
output B is set to Presence.
- NORMAL:
Hold time of 4 minutes minimum for any vehicle detected and
is nominally 30 to 60 minutes for cars. Hold time depends
on loop geometry and number of turns, vehicle size, and position
of vehicle relative to the loop.
- INFINITE:
Continuous detect output is maintained as long as the vehicle
remains on the loop and power is not interrupted for more
than approximately 3 seconds.
Detect
Indicator: Dual color light emitting diode (LED) indicates
output status of detector.
- POWER
ON/NO CALL: Steady green.
- NORMAL
CALL: Steady red while a vehicle is being detected.
- FAILED
OR OUT-OF-RANGE LOOP (WINKY-BLINK™): Three 100 ms blinks
100 ms apart once every two seconds.
Failsafe/Failsecure:
Specify version desired when ordering.
Output
Conditions Tables: Use to determine which version
to order.
Response
Time: Approximately 125 milliseconds after vehicle
enters loop.

at 300 VAC max; 3 hp at 250 VAC.
