Efficient Networks S120 manual Runtime operating hours counter, Total system runtime

Basic functions 6.12 Runtime (operating hours counter)

6.12Runtime (operating hours counter)

Total system runtime

The total system runtime is displayed in p2114 (Control Unit). Index 0 indicates the system runtime in milliseconds after reaching 86.400.000 ms (24 hours), the value is reset. Index 1 indicates the system runtime in days.

At power-off the counter value is saved.

After the drive unit is powered-up, the counter continues to run with the value that was saved the last time that the drive unit was powered-down.

Relative system runtime

The relative system runtime after the last POWER ON is displayed in p0969 (Control Unit). The value is in milliseconds and the counter overflows after 49 days.

Actual motor operating hours

The motor operating hours counter p0650 (drive) is started when the pulses are enabled. When the pulse enable is withdrawn, the counter is stopped and the value saved.

The values can only be stored with a CU320 with order number 6SL3040-....-0AA1 and

version C or higher.

If p0651 is at 0, the counter is de-activated.

If the maintenance interval set in p0651 is reached, fault F01590 is triggered. Once the motor has been maintained, the maintenance interval must be reset.

CAUTION

If the motor data set is switched during the star/delta switchover without the motor being changed, the two values in p0650 must be added to determine the correct number of motor operating hours.

Operating hours counter for the fan

The operating hours of the fan in the power unit are displayed in p0251 (drive).

The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced). The service life of the fan is entered in p0252 (drive). Alarm A30042 is output 500 hours before this figure is reached. Monitoring is deactivated when p0252 = 0.
