Contactors
Condition
monitoring unit
warning “Control"
When the condition monitoring unit indicates the “Control” warning, one of
the start counters 2-7 (ST up), 2-8 (ST down) or 2-9 (ST fast), has
reached the set design limit (the default value is 640,000 operations)
which is defined with parameter 6-19 (Max Control) that calculates the life-
time of the contactors.
When the design limit has been reached, replace the contactors (Up,
Down, Slow, Fast and Brake Contactors). If a brake contactor contains an
auxiliary contact block or a time delay auxiliary contact block, replace that
part as well.
After the replacement, calculate a new value for parameter 6-19. See
instructions in chapter “Contactors”.
If the condition monitoring unit is not used with the hoist, replace the
contactors after six years of operation according to the designed duty
cycle.
