ERROR MESSAGES
Could occur at the start of a pulse train or during a pulse train. Power unit off and
back on. If error message continues there is problem with electronics.
Current not detected. No current ow going to the head. Occurs at beginning of
pulse train. Check 20 amp fuse on the oscillator board. If fuse is ok problem could
be in head or electronics. Replace boards or send back for repair.
Pulse rate is slower than 1 pulse per second. Either low battery, problem with
transformer, or electronics. Charge battery, or replace oscillator board.
Current not detected. No current ow going to the head. Occurs at beginning of
pulse train. Check 20 amp fuse on the oscillator board. If fuse is ok problem could
be in head or electronics. Replace board or send back for repair.
Displayed if duty cycle is reached (100 counts in 4 minutes).
Occurs when XR150 powers up and battery voltage is less than 10V. Indicates
battery low charge, but could re up to 150 counts (450 pulses)
Battery voltage is too low to pulse XR150. Charge the battery.
