Description

ASCO 4000 & 7000 Series Automatic Transfer Switch products utilize the Group 5 Controller for sensing, timing, and control functions. This state–of–the art microproce ssor– based controller includes a built–in keypad and a four–line LCD display. All monitoringand control functions can be done with the enclosure door closed for greater convenience. In addition, all changes in voltage settings (except for nominal voltage) and time delayscanbemadethroughasystemofmenus.

Control Overview

4–line LCD display

On the Power Control Center, six keys allow access to all monitoring and setting functions. Two levels of screens are used. The status level provides information about the automatic transfer switch. The settings level allows configuration of the controller. Access to some settings may require entering a password (if the controller is set for one – see page 2–1 and Appendix A–3).

Tip

☞

Password

Default password is 1111 (see page 2–8)

If Enter Password displays, y ou must enter the correct password first.

Use the up Y and down B arrow keys to change the flashing digit of the password. Press the Enter/Save Settings ¿ keytomovetonextnextdigit (left to right). When the correct password is displayed, press the Enter/ Save Settings ¿ key.

If WRONG PASSWORD !!! displays, you are returned to the first flashing digit. When the correct password is displayed, press the Enter/Save Settings ¿ key.

You can now change the settings on the selected screen.

Once the password is entered it will stay unlocked for 5 minutes after last key is pushed so that you do not have to keep entering it. So, to save time, plan to make all your settings at one time.

Voltage & Frequency Settings

Frequency

Unless otherwise specified on the order, the controller voltage and frequency settings are set at the factory to the default values. If a setting must be changed, carefully follow the procedure on the next page. Some settings may require a password (if the controller is set up for one).

Any indiscriminate change in these settings may affect the normal

operation of the Automatic Transfer Switch. This change could allow

the load circuits to remain connected to an inadequate source.

CP Settings seepage2–1

This display shows the base configuration of the controller. These settings are hardware activated and cannot be changed from the keypad:

Nominal source voltage — Normal and Emergency sources Nominalsourcefrequency—50or60Hz Normal & Emergency source sensing — single or 3 phase Switch type — open, closed, or delayed transition

Normal Voltage seepage2–1

This display shows pickup, dropout, and over–voltage trip settings for the Normal source. They are in percentage of nominal voltage and volts rms.

Normal Frequency seepage2–1

This display shows pickup, dropout, and over–frequency trip settings for the Normal source. They are in percentage of nominal frequency and Hz.

Normal Voltage Unbalance seepage2–1

This display appears only if the CP is set for3 phase sensing onNormal. When enabled, the CP considers the Normal source unacceptable if the calculated voltage unbalance is greater than the specified dropout.

Emerg Voltage seepage2–1

This display shows pickup, dropout, and over–voltage trip settings for the Emergency source. They are in percent of nominal voltage and volts rms.

Emerg Frequency seepage2–1

This display shows pickup, dropout, and over–frequency trip settings for Emergency source. They are in percentage of nominal frequency and Hz.

Emerg Voltage Unbalance (not shown)see page 2–1

This display appears only if the CP is set for 3 phase sensing on Emergency. When enabled, the CP considers the Emergency source unacceptable if the calculated voltage unbalance is greater than the specified dropout.

Commit to Xfer After TD Normal Fail seepage2–1

This display shows the commit to transfer setting. It affects the transfer sequence as follows:

Ye s — If Normal fails, CP continues transfer sequence to emergency

even if Normal returns before Emergency becomes acceptable.

No — If Normal fails, C P cancels the transfer sequence to emergency

if Normal returns before Emergency becomes acceptable.

Shed Load Options seepage2–1

This display appears only for 4ACTS, 4ADTS, 7ACTS, 7ACTB, 7ADTS, or 7ADTB. It determines switch position after the shed load transfer.

IsoLoadOnSrcFail — determines switch position during a source failure.

IsoLoadOnTest17 — deterines switch position during feature 17 activation.

Ye s — Load is not connected to eithersource. (see wiring diagram No — Load is connected to the opposite source. for feature 17 desc.)

Phase Rotation Monitor seepage2–1

This display shows status of phase rotation monitor and desired reference phase rotation. It only appears if both sources are set to 3–phase sensing.

Enabled — Ye s means phase rotation is considered as part of the source acceptability criteria for each source. If the phase rotation of the source does not match the reference phase rotation, that source is considered unacceptable. If phase rotation of the two sources is different, the load will be transferred to the source with the reference phase rotation.

Reference — phase rotation order: ABC or CBA (ABC is default)

In–Phase Monitor seepage2–1

This display appears only for 4ATS, 7ATS or 7ATB. This display shows status of in–phase monitor and in–phase time delay (1.5 seconds is default setting). Enabled — Ye s means in–phase transfer is initiated when any of these conditions are met: Transfer Test (Feature 5) signal, connected source fails, retransfer to acceptable Normal occurs and Emergency source acceptable.

CTTS Bypass / Shed Load (not shown)see page 2–1

This display shows status of the closed–transition bypass options. FailSyncAutoBy pass — Ye s means if the fail to sync alarm occurs, the controller will bypass the closed–transition mode and will make a delayed–transiton transfer. The load disconnect time is set by the Bypass DT Delay parameter. Bypass InPhase — Ye s means the inphase monitor is active during load transfer.
