FAULT CONDITIONS
PEAK CURRENT OVERLOAD
If the peak output current exceeds 40
amps, the output is disabled, and an
error message is displayed. This is usually
caused by a short circuit between the
anode and the cathode. The unit can be
reset by releasing the switch on the anode
pole and pressing it again.
OUTPUT IGBT FAILURE
If there is an output switch (IGBT) Failure,
the unit’s output is shut off and an error
message is displayed.
The criteria for an Output Switch Fault is
that output voltage has been detected
when there should be none. For example,
if the anode pole switch is not activated,
there should be no output from the unit.
If, however, output is detected, then an
Output Switch Fault exists, and the Apex’s
output will be disabled.
Note: The Apex must then be sent back to
Smith-Root for repair. Do not attempt to
use the unit if this message appears, as a
safety hazard may exist, and further use
may cause more damage to the Apex.
AVERAGE CURRENT OVERLOAD
The input and output current of the Apex
are constantly monitored while in use. If
these currents become excessive, the
unit will shut down its output to prevent
damage to its circuits. Releasing the
pole switch and selecting a lower output
voltage or lower duty cycle waveform
should clear this fault.
INVERTER OVERLOAD
If the Output Voltage is set too high for
the water conductivity and the electrode
spacing, the Apex will turn off its output
and display and error message. 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.
If 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 Apex. This occurs when the
water conductivity or electrode spacing
(or both) are such that more power is
being required from the unit 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 unit
can supply on a continuous basis.
LOW BATTERY FAULT
When the battery is less than 20V, the
Apex will shut down its output and display
the Low Battery message. 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
unit will have to be turned off and back on
to clear the message. This test is included
to detect problems in the input current
sensing circuit. If this error message
appears again, the unit will have to be sent
to Smith-Root for repairs.
NOTE:
Make sure the electrode ring is
clean and shiny. A cloudy dull-gray
electrode ring will reduce catch-
per-unit effort and will increase the
fish injury rate (see Electrode Ring
Maintenance, page 42). Initial setup
of voltage, frequency, duty cycle, and
waveform should be done outside of
the sample area.
