Operation time counter
This module counts the operation time. When POS_ACTIVE is active, the count is
continuously added to the time duration until it is deactivated. At any time the OPR_TIME
output is the total duration for which POS_ACTIVE is active. The unit of time duration
count for OPR_TIME is hour. The value is available through the Monitored data view.
The OPR_TIME output is a continuously increasing value and it is stored in a non-volatile
memory. When POS_ACTIVE is active, the OPR_TIME count starts increasing from the
previous value. The count of OPR_TIME saturates at the final value of 299999, that is, no
further increment is possible. The activation of RESET can reset the count to the Initial
value setting.
Limit Supervision
This module compares the motor run-time count to the set values of Warning value and
Alarm value to generate the WARNING and ALARM outputs respectively when the counts
exceed the levels.
The activation of the WARNING and ALARM outputs depends on the Operating time mode
setting. Both WARNING and ALARM occur immediately after the conditions are met if
Operating time mode is set to "Immediate". If Operating time mode is set to "Timed
Warn", WARNING is activated within the next 24 hours at the time of the day set using the
Operating time hour setting. If Operating time mode is set to "Timed Warn Alm", the
WARNING and ALARM outputs are activated at the time of day set using Operating time
hour.
The Operating time hour setting is used to set the hour of day in
Coordinated Universal Time (UTC). The setting has to be adjusted
according to the local time and local daylight-saving time.
The function contains a blocking functionality. Activation of the BLOCK input blocks both
WARNING and ALARM.
