85: PRESSURE SENSOR
FAULT L/H
Pressure sensor / analogue input 01.0 for measu-
ring the oil pressure on the L/H side shows wrong
information. The analogue value it supposed to
send is too low or too high according to specifica-
tion.
The lifting chairs are lifted up by a crane / there is
contact with the ground.
If this is not the case please check pressure sensor
and cable.
86: PRESSURE SENSOR
FAULT R/H
Pressure sensor / analogue input 01.1 for measu-
ring the oil pressure on the R/H side shows wrong
information. The analogue value it supposed to
send is too low or too high according to specifica-
tion.
87: STATUS DYN ZERO L
WEIGHING L/H
Error message for dynamic zeroing failure
VDH9013.
Error messages:
1. ZERO DRIFT ERROR
2. NO ZERO CALIB POINT
3. REPEAT MEASURE ERROR
4. TIME OUT
88: STATUS DYN ZERO R
WEIGHING R/H
89:
Not used.
90: LH HS1 (TILT)
ERRATIC READING
A position sensor difference error caused by
position sensor HS1 on the L/H side.
Linearity check.
This is a timer based interval check, with the bin lift
in motion it checks the old position value and the
current position value. If the difference in position
is too big, this event is remembered in a counter.
When the value of this counter reaches a selected
maximum nr. of errors (5), this message is display-
ed.
Check for axial and radial play where HS1 is
located.
Check the position sensor HS1.
Check the sensor signal on analogue input 00.0
Check the magnet from position sensor HS1.
Check cables and connectors to HS1.
91: LH HS2 (CHAIR)
ERRATIC READING
A position sensor difference error caused by
position sensor HS2 on the L/H side.
Linearity check.
This is a timer based interval check, with the bin lift
in motion it checks the old position value and the
current position value. If the difference in position
is too big, this event is remembered in a counter.
When the value of this counter reaches a selected
maximum nr. of errors (5), this message is display-
ed.
Check for axial and radial play where HS2 is
located.
Check the position sensor HS2.
Check the sensor signal on analogue input 00.1
Check the actuating levers connected to the
sensor.
Check cables and connectors to HS2.
92: LH HS1 (TILT)
OUT OF RANGE
The position sensor HS1 on the L/H side is out of
range.
The analogue input 00.0 value must be between
100 and 900 steps. Any step over or under this
value is not a normal situation.
Check for axial and radial play where HS1 is
located.
Check the magnet from position sensor HS1.
Check the position sensor HS1.
Check the sensor signal on analogue input 00.0
Check cables and connectors to HS1.
93: LH HS2 (CHAIR)
OUT OF RANGE
The position sensor HS2 on the L/H side is out of
range.
The analogue input 00.1 value must be between
100 and 900 steps. Any step over or under this
value is not a normal situation.
Check for axial and radial play where HS2 is
located.
Check the actuating levers connected to the
sensor.
Check the position sensor HS2.
Check the sensor signal on analogue input 00.1
Check cables and connectors to HS2.
94: TIP POSITION
NOT REACHED
Tipping / top position is not reached in time.
This alarm will be on the display together with
alarm messages 13 or 19.
Make sure there is no debris or objects blocking
the bin lift from reaching the fully tipped position.
If no blockage is found please follow instructions on
alarm message 13 or 19.
95: ADJUST DYN ZERO
WEIGHING L/H
VDH9013 weighing dynamic zeroing is active.
96: ADJUST DYN ZERO
WEIGHING R/H
