9.3.7 Current unbalance
Set the warning and trip limits for current unbalance.
For calculation, see section 9.2.9.
Factory setting:
• Warning: 8.0%.
• Trip: 10.0%.
9.3.8 Starting capacitor
Set the warning and trip limits for the capacity of the
starting capacitor.
Factory setting:
• Warning: –25%.
• Trip: –50%.
The values are set as % of the value measured by
the learning function. See section 9.2.12.
Note: Setting is only possible when single-phase
operation has been selected. See section 9.4.1.
9.3.9 Run capacitor
Set the warning and trip limits for the capacity of the
run capacitor.
Factory setting:
• Warning: –25%.
• Trip: –50%.
The values are set as % of the value measured by
the learning function. See section 9.2.13.
Note: Setting is only possible when single-phase
operation has been selected. See section 9.4.1.
9.3.10 Insulation resistance
Set the warning and trip limits for the insulation
resistance in the installation. The value set should be
low enough to allow for an early indication of faults in
the installation.
Factory setting:
• Warning: 100 kΩ.
•Trip: 20 kΩ.
Note:
• Insulation faults must be set to active to enable
these limits. See section 9.4.10.
• Setting is only possible when "3 phases w. FE"
(functional earth) has been selected. See section
9.4.1.
9.3.11 Cos ϕ trip
Set the trip limits for cos ϕ.
Factory setting:
• Max.: 0.99.
• Min.: 0.40.
This function can be used as dry-running protection
when dry running cannot be detected by means of a
current measurement.
9.3.12 Cos ϕ warning
Set the warning limits for cos ϕ.
Factory setting:
• Max.: 0.95.
• Min.: 0.75.
