7. SETTINGS AND ADJUSTMENTS
Screen 1
Basic password “000”
Settings Password 123 for access level that allows adjustment between the
parameters shown only.
Within the Settings menu’s there are two setting ranges
One for user manually initiated transfers using the front panel push
button “Man”
And
Settings that are used under fault detected conditions, “Auto”
It is important that the Auto Settings be set wider than the normal
operating source limits, (e.g. wider than the UPS capability).
Otherwise you may experience unstable operation of the STS
responding to conditions that are normal for the supply.
In general the STSs function is to transfer to the alternate source
when the online source becomes unavailable. The STS should not be
considered as protection against power quality from the source.
There are 5 screens of settings and calibration.
