Error Code Error Cause Elimination
E85 Error in the radius
determination
• The computed radius is too small
(negative deflection)
• Check the programming in
the data EPROM.
E91 No data transmission
form the console to
the central unit
• 24 V supply of the console is inter-
rupted
• Check 24 V at terminal X1
of the console electronics
• Interruption or accidental ground in
the line between console electron-
ics and central unit
• Check the connection con-
sole electronics - central
unit. In case of an acciden-
tal ground, the transmitter
module of the console elec-
tronics might be damaged.
• Transmitter/receiver module is
defective
• Exchange console electron-
ics or LMI main board resp.
E92 Error in the data
transmission from
console to central unit
• Loose connection in the line be-
tween console electronics and
central unit
• Transmitter/receiver module is
defective
• Check the connection be-
tween console electronics
and central unit
• Exchange console electron-
ics or LMI main board resp.
E93 Error in the data
transmission from the
central unit to the
console
• refer to E92 • refer to E92
E94 No data transmission
from the central unit
to the console
• Interruption or accidental ground in
the cable between central unit and
console
• Check wiring to the console
(in case of accidental
ground, replace console
electronics, too).
• 5 V supply of the computer in the
central unit is missing
• Check connection to the
power unit
• 5 V supply is too low • Exchange the LMI main
board
• Transmitter/receiver module is
defective
• Replace console electronics
or LMI main board
• Computer module is defective • Replace processor board.
• Electro-magnetic interferences
(e.g. when switching contactors or
valves)
• Eliminate the source of in-
terferences by inverse di-
odes or varistors.
E95 Error in the console
EPROM
• The console EPROM is defective. • Replace the console
EPROM
E96
