5.6.8 TOTAL RUN HRS

The TOTAL RUN HRS menu records the total run time (unit: hr) of the system components. You can also set
the run time limits of the system components through this menu. If the actual component run time exceeds
the set limit, alarms will be raised.
This menu requires password. You can reset the total run time to zero in order to restart timing.
 Note
Resetting the timers is not needed unless the components are replaced.
The parameters on this menu are described in Table 5-9. Each component has a LIMIT option to set the run
time limit of the corresponding component.
