R-Series Detector and Gate Seasonal Checklist
Before using your detector and gate for the sampling season, we recommend checking and
testing the following. Please contact NMT by email offi[email protected] or phone +1 (360) 764-8850
if you are unable to resolve any issues.
DETECTOR
Are the detector and gate (if you are using one) clean?
Clean with warm, soapy water and rinse well. If scales and slime have hardened
to the detector, you may have to wet the surfaces and let them soak to loosen
and then rinse off.
Check inside the tunnel and around the knobs.
Wash the plastic knob protector with a soft sponge.
Do the knobs on the front of the detector rotate easily? If not, wash around them with
warm soapy water and brush off any corrosion.
Are there any punctures through the enclosure? Check both sides and the top and
bottom. If you find a puncture, you must return the unit to NMT for repair.
Fresh desiccant is blue. If the desiccant is pink, change it. (See User’s Manual for
instructions and source of desiccant material.)
Are the two desiccant cartridge hoses attached correctly?
Ensure that the yellow plugs on the desiccant cartridge have been removed so
that air can freely circulate through the desiccant.
One hose should be attached between the desiccant cartridge and the hose barb
on the back of the detector.
Another 8” hose should be attached to the other end of the desiccant cartridge.
One end of this hose is left open to the atmosphere.
Without the gate, attach power either with the 15 V Power Supply or a 12 V battery and cable
to the Power Connector on rear of detector (some older detectors have a battery tube with 2 c-
cell batteries). Turn on the power.
Do the LEDs light up? After 30 seconds adjust the Sensitivity Knob to the 10:30 position.
The leftmost LED should be on and the 2nd and 3rd LEDs will be bouncing back and forth.
Charge the battery if the low battery light is on. The detector will not function correctly
if the battery power gets too low.
Run a tag through the detector. Does the alarm sound? Do the LEDs reach threshold?
Nov-20 2 GEV
Leave the detector on for 10 minutes. Sometimes if there is moisture inside the
detector it will cause the electronics to malfunction and the alarm will go off without a
tag being present. Does the alarm sound without a tag present? If so contact NMT.
Turn off detector and detach power supply or 12 V battery from detector.
GATE
Attach the gate to detector. Provide power to the gate. Connect gate cable to electronics
connector on the back of the detector.
Turn on the gate power.
Does the Power On LED light up?
If using a battery, is the low battery light on? If so, charge the battery. A low
battery will result in the gate not diverting correctly.
Move the latch hook back and forth. If functioning correctly the gate alarm will sound
when the latch hook is out of position.
Toggle the Direction Switch.
Does latch hook change position? Set direction toggle switch so that the
unlatched door is on the side to which untagged fish are to be diverted.
Carefully open the gate doors.
The rubber bumpers may be
stuck to the gate and they are
easily damaged.
Does your gate have 4
intact bumpers? All
bumpers are needed to
align the gates for proper
diversion; replace any
missing bumpers.
Turn on detector power. Does
the detector power up with the
power attached to the gate? If
not, check that the cable from
the gate is attached to the
Power Connector on the rear of
the detector.
Run a tag through the detector,
does the gate latch release?
When you begin running fish through the detector and gate you will need to set the
Delay and Duration correctly so that a tagged fish diverts when it should. Start by
setting the Delay fully counterclockwise and Duration fully clockwise.

Counter
Check counter function.
Without the cable attached to the counter, press each button and see that the
counter counts up and down. Clear each side by pressing both buttons on that side
at the same time. After clearing the counter should read “0”.
The counter should not be stored with the cable attached. If the cable is left
attached to the counter and the probes are not in the holders on the gate, the
internal battery will drain.
Attach the cable to the back of the counter. Place the cable sensor probes into the
holders on the gate. Secure with the counter keeper springs or elastic bands if the
springs are missing.
Manually open and close each door on the gate. Do counts register on the
counter displays? If the counts are displaying on the wrong display, switch the
sensor probes to opposite sides.
Quad Counter
Check that each counter functions.
Attach cables from switch box to counters. Attach foot switch and cable to gate and
detector.
Check that foot switch works, changing between counters. Check that counts are going
to the correct display of each counter.
