23203 POT HOLE PREVENTION SWITCH
2 - INVALID SIGNAL
2_3
• Pot-Hole State = BLOCKED
The Ground Module detects a redundancy dis-
agreement on the PHP_SW2 input for 500ms.
This error is valid in both Ground Mode and Plat-
form Mode.
X
23204 CHARGE INTERLOCK - INVALID
SIGNAL
2_3
• Charge Interlock State = TRUE The Ground Module detects a redundancy dis-
agreement on the CHARGE_INTRLK input for
500ms. This error is valid in both Ground Mode
and Platform Mode.
X
23205 ELEVATION SENSORS - INVALID
SIGNAL
2_3
• Lift Up State = PREVENTED
• Platform Height Value
assumed to be Full Elevation for
the purposes of other interlocks
• OverLoadState = TRUE
The control system has detected a disagreement
between Elevation Sensor 1 and Elevation Sensor
2. Check the Elevation Sensors and associated
wiring.
•
Only Valid if {MACHINE SETUP->LOAD ? NO}
AND ROTS1_SIG and ROTS2_SIG are not +/-
.25V of the normalized voltage.
•
This fault shall be suppressed if the DTC 252
ELEVATION SENSORS NOT CALIBRATED fault is
active.

FUNCTION PROBLEM - BRAKE
RELEASE PERMANENTLY
SELECTED
None
2_3
In Ground Mode only
• Brake Release State = FALSE
(Brake Release Option is not
allowed to disengage brakes)
In Ground Mode, the Manual Brake Release Digi-
tal Input is energized at power-up. Retained until
the respective Digital Input is momentarily de-
energized.

AMBIENT TEMPERATURE SEN-
SOR – OUT OF RANGE LOW
PF: Continuous 2_4
• Drive and Lift Restrictions
The temperature as communicated by the tem-
perature/tilt sensor is less than -40 degrees Cel-
sius.
•
If Transport State = FALSE, then set Drive
State = CREEP, Lift Down State = MAX Lift Up
State = PREVENTED. The platform alarm shall
continuously sound.
•
If TransportState=TRUE, then set Drive State
= MAX, Lift Down State = MAX, and Lift Up
State = PREVENTED, the platform alarm shall
continuously sound.
X
242
AMBIENT TEMPERATURE SEN-
SOR – OUT OF RANGE HIGH
PF: Continuous 2_4
• Drive and Lift Restrictions
The temperature as communicated by the tem-
perature/tilt sensor is greater than +85 degrees
Celsius.
•
If Transport State = FALSE, then set Drive
State = CREEP, Lift Down State = MAX, and
Lift Up State = PREVENTED. The platform
alarm shall continuously sound.
•
If TransportState=TRUE, then set Drive State
= MAX, Lift Down State = MAX, and Lift Up
State = PREVENTED, the platform alarm shall
continuously sound.
X
251
ELEV ANGLE SENSOR FAULTY –
VOLTAGE OUT OF RANGE
None
2_5
• Lift Up State = PREVENTED
• Platform Height Value
assumed to be Full Elevation for
the purposes of other interlocks
• Arm Guard Functionality shall
be disabled
• OverLoadState = TRUE if
{MACHINE SETUP->LOAD≠NO)
The input voltage from the sensor that measures
lower arm motion is outside acceptable range.
This may be caused by difficulty with the sensor
wiring, or a faulty sensor. Check mounting,
review sensor wiring against the electrical sche-
matic, or replace the sensor to clear the message.
•
Elevation1RawValue from the ROTS1_SIG is
(>4.5V OR <0.50V).
