Peak value
Maximum peak value is 3.5V and maximum effective value
is 2.5 VAC. It is possible that start current gives bigger
output value from current transformers than what are
maximum values, therefore supervisions are by-passed
time of start.
Start time parameters are “4-7-13 Start time to slow speed”
and “4-7-14 Start time to fast speed”.
