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.
