W131 Pre-amplifier temperature is too high.
(>60 °C)
– The ambient temperature is too high.
– The air filter is soiled.
– Heat build-up due to unfavorable position
– Temperature sensor in the pre-amplifier defective.
– After the confirmation of this warning a warning triangle remains in the "Standby" menu, which signals the
existence of this interruption.
The warning triangle disappears as soon as this interruption has been corrected.
W132 Temperature at electronic unit is too low
(<2 °C).
– Ambient temperature too low
– Temperature sensor is defective.
– After the confirmation of this warning a warning triangle remains in the "Standby" menu, which signals the
existence of this interruption.
The warning triangle disappears as soon as this interruption has been corrected.
W133 Temperature at electronic unit is too high!
(>55 °C)
– The ambient temperature is too high.
– Unfavorable position of the leak detector. (heat build-up)
–Fan failed.
– Air filter too heavily contaminated.
– Temperature sensor defective.
– After the confirmation of this warning a warning triangle remains in the "Standby" menu, which signals the
existence of this interruption.
The warning triangle disappears as soon as this interruption has been corrected.
W135 Emission for filament 1 cannot be switched
on.
–Filament 1 defective
– Defective ion source connector or cable.
– MSV board defective.
W136 Emission for filament 2 cannot be switched
on.
–Filament 2 defective
– Defective ion source connector or cable.
– MSV board defective.
W140 EEPROM write timeout – The write command from the MC 68 to the EEPROM was not acknowledged.
–E-EPROM defective.
– Error on wiring board
– MC 68 defective.
W141 EEPROM parameter queue overflow – Software problem. Please contact LACO service department!
W142 All EEPROM parameters lost! Please check
your settings!
– EEPROM on wiring board is empty and was initialized with default values. All parameters must be re-entered
or determined.
– If the warning occurs again after switching back the leak detector, the EEPROM on the wiring board is probably
defective.
– Wrong EEPROM type used.
– New EEPROM is used.
W143 x EEPROM parameters lost! Please check
the settings!
– Missing or invalid parameter value in the EEPROM after switching on the leak detector.
– EEPROM cannot be described. EEPROM defective.
– MC 68 control board defective
– Line connection to EEPROM broken
– Wrong EEPROM type used
W145 x EEPROM parameters initialized! Please
check the settings!
– Missing or changed parameter in the EEPROM and new software version number determined.
– A software update has been performed and one or more new parameters determined. The message can be ac-
knowledged in this case. The parameter(s) is (are) automatically initialized.
