ATS-380 Automatic Transfer Switch

SECTION 1 : INTRODUCTION

1.1 Preliminary Comments and Safety

Precautions

3. Intelligence control unit to constantly monitor the condition of the power sources and thus provide the intelligence necessary for the switch and related circuit operation.

This technical document is intended to cover most aspects associated with the installation, application, operation and maintenance of the ATS-380

Automatic Transfer Switch Controller. It is provided as a guide for authorized and qualified personnel application of the ATS-380 Automatic Transfer

Switch Controller.

This manual deals with the third basic element of the automatic transfer switch, the required intelligence automatic control module. All the

Automatic Transfer Switch functions were performed by a door mounted logic panel ATS-380 control unit. The ATS-380 logic panel brings intelligence, supervisory and programmable capabilities to automatic transfer switch equipment.

1.2 Overview

Transfer switches are used to protect critical electrical loads against loss of power. The load's normal power source is backed up by a standby

(emergency) power source. A transfer switch is connected to both the normal and emergency sources and supplies the load with power from one of these two sources. In the event that power is lost from the normal source, the transfer switch transfers the load to the standby source. Once normal power is restored, the load was transferred back to the normal power source.

1.3 Product Overview

The ATS-380 Automatic Transfer Switch control module is an intelligence, comprehensive, multi-function, microprocessor based automatic transfer switch controller. It is a compact panel mounted device designed to replace traditional relay and solid state logic panels and meet the needs of markets worldwide.

When using the ATS-380 module in automatic transfer switch equipment, the switch's intelligence system initiates the transfer when normal power falls below or over a preset voltage or frequency. If the emergency source is a standby generator, the transfer switch initiates generator starting and transfers to the standby source when sufficient generator voltage and frequency is available. When normal power is restored, the transfer switch automatically transfers back and initiates engine shutdown after a preset engine cooling down time delay.

An automatic transfer switch consists of three basic elements:

1. Main contacts to connect and disconnect the load to the source of power.

2. A transfer mechanism to affect the transfer of the main contacts from one source to another source.

The ATS-380 controller provides an unmatched degree of programmed flexibility to address the needs of most switches system. It can be programmed for 3Ø and 1Ø system operation.

( Refer to program line 2.)

The ATS-380 controller provides the necessary intelligence to insure that the switch operates properly through a series of programmed sensing and timing functions. The ATS-380 controller will :

● Monitor Normal and Standby source over and under voltages.

● Monitor Normal and Standby source over and under frequencies.

● Permit customer programming display real time information.

● Permit customer programming cyclic mode or fix mode display for 3 phase voltages and frequency.

( Refer to program line 29.)

● Permit system testing the transfer switch with/without load from front panel. ( Refer to program line 4.)

● Store customer / factory established parameters in memory without losing.

Normal source to the Standby source. It ensures stability of the Standby source. Timing begins when the Standby Source becomes available. ( Refer to program line 6.)

Adjustable TDNE range : 0 ~ 60 (0 ~ 300 sec)

Feature 2 : Time Delay Engine Start (TDES)

TDES delays the initiation of the engine start circuit in order to override momentary power outages or voltage fluctuations of the Normal source. The

TDES timer shall start when the Normal source becomes unavailable. If the Normal source becomes available while timing, the TDES timer will reset. The ATS-380 controller can perform the time delay engine start function without control power for

30 seconds. ( Refer to program line 7.)

Adjustable TDES range : 0 ~ 6 (0 ~ 30 sec)

Feature 3 : Time Delay Emergency to

Normal (TDEN)

TDEN delays the transfer from the Standby source to the Normal Source to permit stabilization of the

Normal Source before retransfer is made. Timing begins when the Normal Source becomes available.

( Refer to program line 5.)

Adjustable TDEN range : 0 ~ 60 (0 ~ 300 sec)

1.4.2 Standard Features

A variety of programmable features are available to meet a wide variety of application requirements.

Individual features or feature combinations provide the Intelligence required tailoring switches to individual needs. The features can be programmed by customer via friendly setting procedure, depending upon customer requirements. The specific variable set points associated with standard and factory activated features are stored in a nonvolatile memory. Activated feature set points are available for customer adjustment.

Feature 4 : Time Delay Engine Cool-down

(TDEC)

TDEC permits the generator to continue to run unloaded after retransfer to the Normal Source has occurred. Timing begins when the transfer to normal has been completed. ( Refer to program line 8.)

Adjustable TDEC range : 0 ~ 60 (0 ~ 300 sec)

This feature provides for automatic test operation of the generator. The interval is fixed at once per week with a specific test day and time. The test period is also programmable by customer setting. The

ATS-380 control unit permit customer plant engine test with / without load on a preset period. ( Refer to program line 21,22,23,25,26,27 & 28.)

Feature 10 : Transfer Fail Alarm Signal

Output

When the auxiliary contactor was set to be a transfer fail alarm output. The auxiliary contactor may be wired to an alarm enunciator panel to indicate problem with the Automatic Transfer

Switch.

An alarm condition will occur if a transfer has been initiated but it is never completed. This may indicate that something is wrong with the motor or transfer mechanism. ( Refer to program line 30 )

NOTICE

The ATS-380 controller provided an aux. contactor for external signal output only. So, this contactor just can define to one of the three features used. (Pre-transfer, Pre-exerciser or Transfer fail alarm output.)

Feature 8 : Pre-transfer Signal Output

When the auxiliary contactor was set to be a pre-transfer signal output. The ATS-380 controller will provide a pre-transfer signal to elevator controller before transfer the load from one source to another source with a preset time delay. The pre-transfer return to normal state after the transfer is complete. ( Refer to program line 30 & 31.)

Adjustable range : 1 ~ 99 sec.

Feature 11 : Fail Alarm On Display

FAIL on the front panel of the ATS-380 indicates that a transfer was initiated but never completed. This can point toward a defective motor, transfer mechanism or the wrong programming for line

3.When the transfers fail alarm occurred, the ATS will hold this position until the OFF button is pressed to reset alarm signal.

NOTE! Normally, MCCB type ATS need longer running time to complete there cycle, so if line 3 is set wrong the switch stops before completing it’s cycle and the ATS-380 will give you a FAIL transfer

Alarm. Make sure the line 3 setting is set right before checking any other parts of the ATS mechanism.

Feature 9 : Pre-exerciser Signal Output

When the auxiliary contactor was set to be a pre-exerciser signal output. The ATS-380 controller will provide a pre-transfer signal output before exerciser the engine. It is an advance warring to avoid person damaged before the generator auto start itself. ( Refer to program line 30 & 32.)

Adjustable range : 1 ~ 99 sec.

4.3 Engine Test Mode

The ATS-380 is provided with a test pushbutton that simulates a loss of normal source. Pushing the

TEST key on the front of panel, the ATS-380 will run in engine test mode. The TDES and TDNE programmed time delays will be performed as part of the Test. There are two test modes:

● With load engine test.

● Without load engine test. (The TDNE time delay will not be performed)

When the user terminated the engine test mode by press the AUTO pushbutton, then the controller will return to automatic mode. When normal power is available, the transfer switch automatically transfers back from standby source to normal source and initiates engine shutdown after a preset engine cooling down time delay.

When the user terminated the engine test mode by press the OFF pushbutton, the ATS will keeps the present status and the ATS-380 controller initiates engine shutdown immediately without cooling down time delay and returns to off mode.

4.4 Off Mode

The off mode of the ATS-380 controller will disable all the transferred and protected functions, and all the status LEDs will be turned off in this mode. The real time clock will be showed on the front display window.

In the event that power is lost from the normal source, the ATS-380 controller will not start the engine and the ATS can’t transfer the load to the standby source automatically.

When in program mode, pushing the off pushbutton allows the user to change the program line table and set the selected parameter using decrease ( ▼ ) or increase ( ▲ ) button.

Begin to start programming mode, set the

ATS-380on off mode, push the button “ increase ( ▲ )

& decrease ( ▼ ) ” on the front panel for 4 seconds.

The word “ Ver 1.0 ” will appear on the front display window for 2 seconds. This number indicates the version of the software.

You are now ready to start a line by line programming sequence. To advance to the next line, push the OFF button on the front panel. To change each line’s programming parameters, press the increase ( ▲ ) and decrease ( ▼ ) buttons. When pressing and releasing the increase ( ▲ ) or decrease ( ▼ ) key the displayed parameter can be increased or decreased by one. The Increase ( ▲ ) or decrease ( ▼ ) pushbutton will continue to scroll if it is pressed and not released.

Always push the “ OFF ” button to advance to next programming line or until the word “ END ” appears on the screen. To immediately end the programming mode, you can simply push the “ OFF ” button for 4 seconds at any time. Then the word “ END ” on the display window indicates the end of the programming mode.

Should you make an error or desire to return to factory settings, stay in programming mode and simultaneously press all 3 buttons : increase ( ▲ ), decrease ( ▼ ) and OFF for 4 seconds. The ATS-380 controller will now automatically program itself to factory settings and the word “ Au.Po ” will appear on the display window. ( See line by line programming table for ATS-380 factory settings. )
