Circuits Configuration and Setup

Press the Circuit Setup button to enter Circuit Setup mode. When the circuit setup messages are displayed

they appear in the same order as they are listed in this section.

Circuit Setup

Circuit setup begins with Circuit 1, and proceeds through all of the configuration settings for Circuit 1

before moving on to Circuit 2, the same is true for Circuit 2, then Circuit 3, and so on.

This value is used to determine the response speed of the

ALM algorithm. When the power output from the UPS source

surge exceeds the power rating (set earlier in this section) for

the specified

UPS SRGE OVERLD TIME (a value in the

[0-60] SEC range), then load shedding will be activated.

Load shedding occurs when the rated output power of the

UPS is exceeded for longer than the

SRGE OVERLD TIME.

Note If you reduce the surge overload time it reduces the likelihood that the UPS will be

overloaded, but it increases the chance that load shedding will occur.

If you increase the surge overload time it increases the likelihood that the UPS will

be overloaded, but decreases the chance that load shedding will occur.

Select

YES to reset all configurable parameters to the factory

default. Selecting

YES also restarts the UTS Setup Wizard,

which is described in Initial Setup in the Universal Transfer

Switch Site Preparation and Installation Guide (Document

No. 990-2992A).

Note Use the Up Arrow and Down Arrow buttons to move between displays, and to

change settings. Also, note that settings change immediately as soon as the Up

Arrow or Down Arrow button is pressed.

Note To configure a particular circuit, use the Circuit Status button and change the

display to show the desired circuit (for example, CKT3), then press the Circuit

Setup button. The setup screen for that particular circuit will be displayed.
