1,01
Mast Down (mag switch)
- Sensor State Error
This is only checked at
power up, if stowed.
Sensor outputs are O.K.,
but it is indicating that
the mast is extended
(not down)
1. The magnetic sensor
is not being energized or
is defective
2. Mag switch out of
position
1,02
Mast Stowed (near 0°) -
Sensor Output Error
Sensor outputs are bad
Defective sensor or
defective board
1,03
Mast Stowed (near 0°) -
Sensor State Error
Sensor outputs are O.K.,
but sensor shows wrong
polarity for nested state.
The board remembers
where it was (0° or 90°)
when it was shut off, and
this time it powered up,
it's sensing the opposite
condition
Base board was
changed or software
was updated with the
mast at 90°
1,04
Excessive amp draw
during actuator decline
Current sensor
indicating it has
exceeded:
(12v systems) 10A for
100ms
(24v systems) 6.0 amps
AND less than 10 amps
for (100 msec)
If mast stops at ~70°
and issues error, replace
Base Board. Current
sense circuit has failed.
If error occurs during
nesting, check LED D7
"MAST STOWED (near
0°)". Once the sensor
"sees" the magnet, it
allows 0.5 sec to see the
(nesting) current rise. If
the circuit does not see
the sensor, it does not
look for nesting current
to shut down. It will keep
driving into the saddle
and then issue a 1,04.
Re-adjust Near 0°
sensor.
Bad actuator - AC
component in current
wave shape due to
internal mechanical
problem. Replace
actuator.
1,05
Well Open (Vertical with
well cover) - Switch
Output Error
Sensor outputs are bad
Defective switch or
wiring error. Refer to
System Wiring Diagram
