APPENDIX B: LR-24 EVENT CODES
The following are the event codes that the LR-24 logs in its internal event history. Each
entry contains a code followed by the hardware time when the event happened. This time
represents total shocking time since the LR-24 was built.

Description
Cleared By
U01
LR-24 Tilted Too Far
LR-24 has been tilted from verti-
cal beyond safe limits.
Pole Switch
U02
Immersion Detected
LR-24 has been immersed in
water.
Power On/Off
U03
Low Output Current
Electrodes may be out of the
water.
Pole Switch
U04
Pole Switch on at Power-up.
Pole switch engaged when
power was turned on.
Pole Switch
U05
Voltage detected on output
A voltage above 30V is seen on
the electrodes when the output
is turned off, likely due to other
LR-24s.
Automatic
P01
Peak Amps Overload
Electrodes likely have been
shorted.
Pole Switch
P02
Low Battery Voltage
Battery has been drained, needs
recharging.
Power On/Off
P03
Over Temperature
LR-24 has gotten too hot, let
cool.
Pole Switch
P04
High Battery Current
Too much power from battery,
reduce output voltage or duty
cycle.
Pole Switch
P05
High Output Current
Average output current above 4
Amps, reduce output voltage or
duty cycle.
Pole Switch
P06
Inverter Overload
LR-24 unable to maintain re-
quested output voltage into the
current load. A lower output
voltage will be suggested to help
prevent failure. May require sev-
eral attempts to find a voltage
that will work.
Press Enter Key on Keypad.
