LR-24
BACKPACK ELECTROFISHER
INVERTER OVERLOAD
If the Output Voltage is set too high for the water
conductivity and the electrode spacing, the LR-24 will
turn off its output and display an error message (
Fig.
4.12
). The error message will suggest a more appropriate
voltage for the present conditions. If this error is caused
by a mistake, for example, temporarily having the Anode
and Cathode too close together, acknowledge the error
message by releasing the pole switch and pressing any key
on the keypad.
If the the error message shows up again in a short time,
acknowledge the message and reduce settings to the
suggested voltage before proceeding. This message
occurs when the output voltage drops more than 30%
below the voltage the user has set on the LR-24. This
occurs when the water conductivity or electrode spacing
(or both) are such that more power is being required from
the LR-24 than it can supply. Note the average and peak
power readings on the display. While the average power
may be quite low, the peak power will be far above the
400 watts the LR-24 can supply on a continuous basis.
LOW BATTERY FAULT
When the battery is less than 20V, the LR-24 will shut
down its output and display the Low Battery message
(
Fig. 4.13
).
Turn off the power and replace the battery with one fully-
charged to clear this fault.
BATTERY CURRENT TOO LOW
If the input current measuring circuit does not measure
any current, this error message will appear and the power
to the LR-24 will have to be turned off and back on to
clear the message (
Fig. 4.14
). This test is included to
detect problems in the input current sensing circuit. If this
error message appears again, the LR-24 will have to be
sent to SRI for repairs.
