Function Summary
Table 3.G Protective Functions Summary
➊ Via external speedometer (control input #1), output and trip relays as for high overload.
➋ Allowing for the ambient temperature in the thermal image.
➌ Only one relay per function can be selected: MR = main relay, AL = alarm relay, auxiliary relay #1…#5 (if
auxiliary relays #2 and #3 are assigned to the communication [refer to page 5-16] they cannot be selected
here).
