13.2 Warnings
13.2.1 General warnings
The warning state means that at least one calculated condition monitoring value has exceeded the
corresponding design value of the hoist. Any active warnings are indicated with the corresponding text on
the display. The warning text appears on the display directly when the value exceeds the design value,
and each time after switching the power on to the hoist control unit, until the warning is cleared. Moving
to the load status display is carried out with the arrow buttons of the display. In addition, the LEDs in the
unit and display are blinking.
Warning name Description
SWP% The calculated relative safe working period SWP% is less than zero
Starts The actual number of hoist starts has exceeded the design limit
Run time The actual value for the hoist run time has exceeded the design value
Br SWP% The calculated value for the brake SWP% is less than zero
E-stops The number of interrupted hoists has exceeded the design limit
Control The number of actual control actions has exceeded the design limit
ST MFI1 *1) The starts counter for MFI1 has exceeded the given maximum value
RT MFI1 *1) The run time counter for MFI1 has exceeded the given maximum value
ST MFI2 *1) The starts counter for MFI2 has exceeded the given maximum value
RT MFI2 *1) The run time counter for MFI2 has exceeded the given maximum value
If any warning is active, the hoist will still run normal, but safe using is not guaranteed.
*1) When the programmable inputs MFI1 and MFI2 are used as start and run time counters, the
corresponding operation must be selected with the parameters. Otherwise the starts and the run
time values are not counted and the warnings related to MFI1 and MFI2 do not activate.
When warning has activated check actions from the Hoist’s GO – manual or ask from crane factory.
13.2.2 Service warnings
Service warning state is activated when at least one of the monitored items has exceeded the limit set by
parameter group 5. Service warning status is indicated with the corresponding text on the display. The
service warning text appears on the display directly when the service warning state becomes active, and
each time after switching the power on to the hoist control unit, until the warning is cleared. Moving to the
load status display is carried out with the arrow buttons of the display. In addition, the LEDs in the unit
and display are blinking. If any service warning is active, the hoist can still be run normally.
Name Description
Run time The actual value for run time has exceeded the set service limit value
Starts The actual value for the start counter has exceeded the set service limit value
SWP% The actual value of SWP% is less that the set service limit for SWP%
Br SWP% The calculated brake SWP% value is less than the set service limit value
When service warning has activated ask actions from crane service company
