9.1.5 Current

For the purpose of the current limits and the meaning of a current fault, see Section 6.7, “Current monitoring”; the I²t load is explained in Section 6.8, “Power limits and power reduction”.

STR-00 Current

Current the channel that is currently measured

Unit A

STR-01 Lower limit

Warning as soon as less current flows than specified here.

Unit A · Range 0.0…16.5 · Factory setting 0.0 · from #3 Master

STR-02 Nominal current

Current value determined during the last current measurement for the nominal case.

Unit A · Range 0.001…16.5 · Factory setting 7.5 · from #3 Master

STR-03 Upper limit

Warning as soon as more current flows than specified here.

Unit A · Range 0.0…16.5 · Factory setting 15.0 · from #3 Master

STR-04 Measurement

Switch on the channel to measure the current. Then the lower and upper current limits are reset. The following options are available:
  1. Only measure!: The rated current and the current limits are not changed. The measurement result appears under “Notifications”.
  2. Copy nominal current: The rated current is reset, the current limits are not changed.
  3. Min/Max ± 0.1 A: The current limits are set +0.1 A to the maximum and −0.1 A from the minimum measured value.
  4. Min/Max ± 0.5 A: The current limits are set +0.5 A to the maximum and −0.5 A from the minimum measured value.
  5. Average ± 10 %: The current limits are set ± 10 % of the measured mean value.
  6. Average ± 25 %: The current limits are set ± 25 % of the measured mean value.
  7. Average ± 0.5 A: The current limits are set ± 0.5 A from the measured mean value.
  8. Average ± 1.0 A: The current limits are set ± 1.0 A from the measured mean value.
  9. Mean ± prev. Tol. %: The current limits are set within the existing limits of the newly measured mean value.

STR-05 I²t

Display of the current I²t load of the channel as a percentage. The value is a display only and cannot be set; the reference values are defined device-wide by customer service.

STR-06 Current error: turn off

If the check mark is set, the channel is automatically switched off in the event of a current error.
