・When load current is under the setting current for time measurement (HM-A), it measures as OFF-time.
When load current is exceeded to the setting current for time measurement (HM-A), it measures as
ON-time. Current for time measurement (HM-A) is set to under cutoff current (CUTA), all current is
measured as OFF-time.
・Maintenance time
It measures maintenance time. Use it when you don't measure either OFF-time nor ON-time, for
example the load is under maintenance.
It measures ON signal input with the pulse input terminal as maintenance time. Actual work time is the
total time of ON-time2, ON-time1 and OFF-time.
Hour meter function can be used only with main unit and one expansion unit.
2 or more expansion units can't be used hour meter function.
・Ratio of ON-time
It displays ratio of ON-time calicurated with actual work time and ON-time as below.
[Calicuration method of Ratio of ON-time]
Ratio of ON-time1＝ON-time1/(actual work time－Maintenace time) ×100(%)
Ratio of ON-time2＝ON-time2/(actual work time－Maintenace time) ×100(%)
However, for ratio of ON-time, it uses measuring value inside every 1 sec., therefore it may be different
when you compare with displayed OFF-time, ON-time1, ON-time2, maintenace time and actual work
time.
