Error list in diagnostic menu
All error-messages are stored in an error-list. How to display the error list - refer to chapter “ Diagnostic function
control unit ”.
Error interpretation
Restrictions and remarks:
Below description refers to SW 1.87 in the control unit and 2.4 or 4.4 in optics carrier.
Error messages caused by the Iris diaphragm in M525 optics carrier are NOT displayed in M500 N / M520 control unit.
Level-1 messages are underlined, all others are Level-2 messages.
MF means multifoc controller / motor controller .
Error messages caused by the optics carrier:
Error message
Description Remedy
Microscope error/warning out of
range
Control unit received an unknown error
code from optics carrier.
Check compatibility of software in
control unit with software in optics
carrier.
Microscope needs initialization
Power-up-reset happened to optics
carrier; therefore motor positions are not
defined.
Release “initialize microscope” in
menu II.
Microscope initialization failed Initializing command, sent to optics
carrier, is not executed within 45
seconds.
If no problem with CAN
communication it is a problem of
motor controller in optics carrier.
Activating user parameter failed Motor positioning commands, sent to
optics carrier, are not executed within 45
seconds.
If no problem with CAN
communication it is a problem of
motor controller in optics carrier.
No status response from
microscope No status response from optics carrier
within 5 seconds.
If no problem with CAN
communication it is a problem of
motor controller in optics carrier.
Microscope detected (config. error) Optics carrier was found on CAN bus,
although it is set to NOT PRESENT.
Set optics carrier in device list
PRESENT.
Microscope not detected (config.
error) Optics carrier was not found on CAN
bus, although it is set to PRESENT. Set optics carrier in device list
NOT PRESENT.
IGS Calibration Code setting error Problem writing IGS calibration code to
optics carrier.
•
SW in optics carrier must be
2.4 or higher
•
No reply from IGS
workstation on CAN bus
•
Code does not match with
calibration code of IGS
workstation
MF: CAN 96 communication errors More than 96 transmission errors did
occur on CAN bus; bus communication
is launched again.
•
Check CAN cables
•
Electronic problem on CAN
controller like inaccurate bit
rate or faulty bus
transceiver chip.
MF: Watchdog expired, rebooted Watchdog expired – program crashed;
resulting in power-up boot. As long as position counters did not
loose their values, normal operation
possible. Else release “initialize
microscope” in menu II.
