Root Issue
Current sensor indicating it
has exceeded:
(12v systems) 10A for 100ms
(24v systems) 6.0 amps AND
less than 10 amps for (100
msec)
Sensor outputs are bad.
Switch outputs are O.K., but
show wrong polarity for
closed state.
No successful poll / response
communication for 250ms.
Internal state machine logic
has detected an invalid state
transition. Firmware logic
error.
Init input has remained active
for 5 seconds. Input is stuck,
or has been hot-wired.
Memory Error
During decline, the Base
board senses actuator
current. After the "Near 0°"
sensor is detected, it is
expecting to see the current
level rise before it stops. This
error indicates the sensed
current has stopped before
nesting.

Potential Cause
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.
Defective switch or wiring error.
Refer to System Wiring
Diagram.
Well cover open or wiring error.
System is expecting the well
cover to be closed at power-up.
1. Unit is in NFPA mode and
connected to a Non-NFPA J-
box. (Note: if the unit is in Non-
NFPA mode and connected to
an NFPA junction box, the unit
will look normal (UP led on
HHRC on), but will not respond
to the HHRC. The software is
expecting to see the init signal
always on. No error message is
generated).
2. Wiring short in the control
cable or defective switch/wiring
in the junction box.
Memory Error
If it occurs near the nested
position:
Actuator has reached its
internal stop before nesting
completed, most likely saddle
too low or saddle not secured
causing sideways movement
when nesting.
