Troubleshooting
Checking Detector Operation
DO NOT perform the following
procedure until you have thoroughly
reviewed configurator software settings.
procedure until you have thoroughly
reviewed configurator software settings.
1. Verify all boards are properly seated and all
cables are securely plugged in.
2. Turn on the circuit breaker.
3. Connect the laptop computer to J5 on the main
circuit board and load the configurator.
Note: After power is applied the detector
passes its power-up test, the power
on/heartbeat LED (DS2) should start flashing
once per second. If it does not flash, check for
an error condition using either the laptop
computer or by observing LED DS5 on the
board. Refer to Figure 5 for the location of DS2
and DS5. Refer to the section entitled
“Understanding Error Codes” on page 11 for
interpretation of the codes.

4. Close the base cover and verify the transmit
current is at least 25A. If it is less than 25A, go
to the section “Tuning the Pedestal” on page 9.

5. Check the following:
•
If validations occur with no tags/labels
nearby, increase the Minimum Threshold or
change the Sensitivity in 1dB increments
until validations cease.

If this Ultra•Max detector is causing another
to constantly alarm or not detect, or vice
versa, check the System Noise Average
screen. If the bar meters are constantly
reaching the maximum values, then adjust
the Zero Crossing Delay.

•
Check the vicinity for tags or labels.
•
If a lot of noise is entering the detector but it
is lower when the Polarity of the detector is
set to “Figure-8” than when it is set to
Aiding, set the Polarity to “Figure-8”.

Set audio and LED durations.
6. Disconnect the laptop cable. Detector operation
has now been verified.
Dead system/Low sensitivity
A detector that is dead or has low sensitivity may
be without power, in the wrong mode, or affected
by noise from an electronic device such as a TV
set or PC monitor, or from certain fluorescent,
halogen, or neon lamps. To diagnose the problem,
you use the Mode LED (DS2) inside the primary
base cover. Refer to Figure 6 for the location of
DS2.

1. Observe the Mode LED (DS2). In what state is
the lamp?
•
Off - No power
•
Steady (not flashing) – Service Mode
•
Flashing twice a second – Hidden Tag Mode
•
Flashing once a second – Normal Mode
2. Use the following table to determine the
problem/action to take.

Problem/Action
Off
The detector has no power.
1. Ensure the detector is connected
to the AC power source.
2. Check the circuit breaker in the
store’s breaker box. If the
breaker tripped, reset it and
check system performance. If the
breaker will not stay on, call
maintenance. If the breaker is
OK, the detector needs service.
Call for assistance.
