Status Information

Thecontrol ler (CP) provides the status of the automa tic transfer switch (ATS) and

of both the normal and emergency sources. This information is at the status level

of all screens and no password is required to view them.

Youcanpress the right arrow "key to see the status of the Normal Source or press

the left arrow Akey to see the status of the Emergency source (the me nus loop

back).

NORMAL OK

EMERG SOURCE NORMAL SOURCE

ATS Status

The ATS Status is the primary display. It shows the present status of the ATS.

Transfer sequence status and running time delays are shown. For inphase or

closed–transitiontransfers, phase relation between the sources is also shown.

The ATS Status display can be directly reache d from anywhere in the menu

structure by pressingthe Esc key threetimes .

Normal Source Status

The Normal Source Status display shows the rms voltage of each of the phas es, the

sourcefrequency in Hz, and the phase rotation. Ifenabled, thevoltage unbalance

will also be displayed.

Emergency Source Status

The Emergency Source Status display shows the rms vol tage of each of the phases,

the source frequency in Hz, and the phase rotation. If enabled, the vol tage

unbalance willalso be displayed.

Source Acceptability

The CP considers a source unacceptable if any of these conditions are tr ue:

SAny phase voltage of the source is less than the voltage dropout setting.

SAny phase voltage is greaterthan voltage trip setting for more than 3 sec.

SFrequency of the source is less than the frequency dropout setting.

SFrequency is greater than frequency tri p setting for more than 3 seconds.

SPhase rotation does not match specified phas e rotation (only if enabled).

SThe phase unbalance is greaterthan the unbalance dropout setting (only if enabled).

The CP considers a source acceptable again when all these conditions are true:

SEach phase voltage is greater than the voltage pickup setting.

SEach phase voltage is less than trip voltage setting by more than 2% of nom

SThe frequency of the source is greater than the frequency pickup setting.

SFrequency is less than the frequency trip setting by more than 2% of nom.

SPhase rotation matchesthe specified phase rotation (only if enabled).

SThe phase unbalance is less than the unbalance p ickup setting (only if enabled).
