fish passing through the detector causes the Diverter Gate latch to toggle before
the previous fish has completely exited the gate, and well before the fish in the
Detector reaches the Gate. In this case the Gate Signal Delay may be turned
up, causing the signal from the Detector to the Gate to be delayed until just
before the fish reaches the gate doors.
Fine Adjustment of Gate Signal Duration:
After increasing the Delay, the Signal Duration should be decreased. At the
initial setting, the signal that activates the gate remains on longer than necessary
after a tagged fish passes through the gate. For faster operation, the operator
must turn the Gate Signal Duration adjustment down so that the Gate is ready
for another fish more quickly after the passage of a tagged fish. The Duration
may be decreased until fish are just diverted before the signal is stopped and the
latch reverts to the default position. The gate duration signal must remain on until
the tagged fish has passed at least partially through the gate, or the tagged fish
may not be correctly diverted.
The Diverter Gate allows dependable operation at speeds up to 1 fish per
second. Note that performing this Fine Tuning allows for faster operation, faster
operation requires greater skill and care by the operator to avoid errors
caused by fish that are too close together, especially with two or more
people feeding fish.
Stand-Alone Operation
In order to ensure the longest battery life, disconnect the battery cable from the
Power Connector on the rear panel of the detector when the detector is not in
use.
Counter Operation
The Dual Counter (formerly R-Series Detector Gate Counter) has two identical
counter displays and pairs of control buttons. Each display indicates the sum of
counts for the right or left side. The sum is incremented every time the
corresponding gate door opens. The sum may also be increased or decreased
by pushing the + (Red) or – (Black) button (or holding the button for repeated
changes), or reset to zero by pressing both buttons simultaneously.
When checking for proper functioning of the Counter, be sure that both sensors
