Message
1,08 Internal firmware
detected error
1,09 Initiate Pushbutton input
error
1,10 Memory Error
1,11 Actuator current has
unexpectedly stopped
1,12 Sensor Output Error
Roof-mount - Actuator at
90° magnetic sensor
Vertical - Upper mag-
netic sensor switch
TP-4602001-T
DECEMBER 2020
Meaning
Internal state machine
logic has detected an
invalid state transition.
Firmware logic error
Initiate 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 indi-
cates the sensed current
has stopped before
nesting
Sensor outputs are bad
OPERATING INSTRUCTIONS
Root Issue
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 gener-
ated).
2. Wiring short in the
control cable or defec-
tive switch/wiring
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 move-
ment when nesting
Wiring error, faulty sen-
sor
(Vertical only) mag
switch positioning. Note:
Sensor is only active as
mast tube magnet goes
by. Software watches for
direction of travel and
sensor activation to
determine if mast is "up"
or "down"
