DIAGNOSTICS
This chapter covers the diagnostics for the UDL2 controller, with special reference to the 900 series firmware. We cover the meanings of the
display codes, which errors are displayed (their meanings and how to reset them) and the operation of the tSt program.
Code on
display
Programs for ramps with hinged lips (P11
– P12 – P13)
Programs for ramps with telescopic lips (P21 –
P23 – P25 – P31 – P32 – P33)
Note
P… Valve setting. P1x = single-valve ramp Valve setting. P2x, P3x = two/three valve ramp.
LF Sensitivity of electric motor thermal cutout Sensitivity of electric motor thermal cutout [min]
LE N/A Minimum telescopic lip extension time [s]
LA N/A Maximum telescopic lip extension time [s]
LN N/A Difference between telescopic lip retraction/extension
times [s]
During AUTORETURN, coincides
with status 00D
LR The time employed by the ramp in travelling
from its maximum height to its standby
position [s]
The time employed by the ramp in travelling from its
maximum height to its standby position [s]
Coincides with status 00E
RB Time available for industrial gate to close
before it is locked out [s]
Time available for industrial gate to close before it is
locked out [s]
If interlocking is implemented, this
coincides with status 00F
LC The time employed by the ramp in travelling
from its minimum height to its standby position
[s]
The time employed by the ramp in travelling from its
minimum height to its standby position [s]
Coincides with status 00C
AR Presence of AUTORETURN button Not used
PC Sensitivity of current measurement used to
detect the position of the lip while opening
Enables/disables the movement of the lip when it is
floating
In P31, one refers to status 00A
BU Determination of ramp operating mode and
number of available buttons
Determination of ramp operating mode and number
of available buttons
LL Not used Length of telescopic lip 5 = 500mm
1 = 1000mm
001 Auto-test 1 Auto-test 1
002 Auto-test 2 Auto-test 2
003 Auto-test 3 Auto-test 3
004 Ramp waiting to be enabled Ramp waiting to be enabled Waiting to detect vehicle / chock
positioning / industrial door
opening
005 Ramp enabled Ramp enabled Ramp ready to move
006 Ramp UP Ramp UP After 2s changes to status 007
007 Rotation of hinged lip Ramp UP
008 N/A Extension of telescopic lip
009 Lip fully open and Ramp DOWN Ramp DOWN
010 Shelter / chock / vehicle detectors still active Shelter / chock / vehicle detectors still active
011 Anti-collision function tripped Anti-collision function tripped Press AUTORETURN to quit
012 Incorrect floating position – the lip is properly
positioned on the vehicle
Incorrect floating position – the lip is properly
positioned on the vehicle
023 UDL2 controller first startup UDL2 controller first startup Press UP ARROW to continue
025 PEEP module programming PEEP module programming
026 Operating mode and parameter programming Operating mode and parameter programming
027 Display PEEP module programming (read only) Display PEEP module programming (read only)
00A Floating position correct Floating position correct
00C Ramp UP after AUTORETURN pressed Ramp UP after AUTORETURN pressed
00D N/A Retraction of telescopic lip
00E Ramp DOWN after AUTORETURN pressed Ramp DOWN after AUTORETURN pressed
00F The ramp has reached the base (standby
position) / waiting for industrial gate to close
The ramp has reached the base (standby position) /
waiting for industrial gate to close
If interlocking implemented
SEr Loading ramp full cycle counter Loading ramp full cycle counter Increments in status 00C
A01 RAM / ROM error RAM / ROM error
A02 Procedure error Procedure error e.g. chock removed during
loading/unloading
A03 Electric motor power fault Electric motor power fault e.g. three-phase not available /
star/delta connection incorrect /
insulation damaged / short circuit
