1.7.1 Unloaded System Test

When an unloaded test is initiated, the controller immediately signals the generator to start, without waiting for the engine start time delay to expire. The contactor does not change position during an unloaded test, but if the normal source should fail, the contactor will transfer to the emergency source.

The unloaded test feature is available only with the Util-Genset and Genset-Genset modes of operation.

The load bank control output is active during an unloaded exercise or unloaded system test. If the contactor transfers to the standby position during the test, the load bank control is deactivated. (The standby source supplies power to the load.)

1.7.2 Loaded System Test

A loaded test simulates a preferred source failure, except that the engine start time delay is bypassed. The generator set is signaled to start immediately upon test activation. Load control signals are issued prior to transfer with their associated time delays. Since the loaded test transfer will be between two live sources, the in-phase monitor or closed transition feature will be activated if it is enabled. If the preferred source is lost during a loaded test with the contactor in the standby position, the test will continue to be active, even on restoration of preferred. If the standby source is lost and the preferred source is available, the test will be terminated, and the transfer switch will immediately transfer to the preferred source position, bypassing all time delays except the off-position requirements in a programmed-transition system.

When a loaded test is terminated normally, the retransfer sequence operates as though the preferred source has been restored after a failure. All time delays are executed and an in-phase transfer will occur if enabled. The loaded test feature is available with the Util-Genset, Util-Util and Genset-Genset modes of operation.

Norm ###V Emer ###V

End End

Main Delay Test

When a loaded test is initiated on a closed-transition model, the generator set is signaled to start and the controller monitors the sources for synchronization. The load is transferred when the sources are synchronized.

Note: See Figure 1-16 for Sync Check menus.

Figure 1-13 Test Sequence Menus

TP-6883 4/21 19Section 1 Operation

If the sources do not sync before the Fail to Sync time delay expires, the programmed-transition override function operates.

D If the override function is set to Automatic, a

programmed-transition transfer will occur when the Fail to Sync time delay expires. The contactor stops in the OFF position for the length of the off-to standby time delay before proceeding to transfer to the standby source.

D If the override function is set to manual, the user can

either initiate a programmed-transition type transfer (setup password required) or cancel the test sequence. See Figure 1-14. If neither action is taken, the controller will continue to check for synchronization and transfer if the sources synchronize.

See Section 4.11.3 for instructions to set the programmed-transition override function.

1.7.5 Sync Check (closed-transition)

The Sync Check allows a test of the synchronization of two available sources without initiating a transfer. Navigate to the Type of Test, Sync Check menu and press the Start button to begin the test. The controller displays Syncing during the test, and the phase angle difference is shown between two arrows. For example, > 10 < indicates that the sources are 10 degrees out of phase. The arrows move closer together as the sources approach synchronization. When the sources synchronize, the controller indicates Synced and continues to monitor the source synchronization. The load is not transferred. See Figure 1-16. Press the End Te st button to end the test.

Section 2 Sequence of Operation

This section explains the transfer switch sequence of operation during the following events:

D Controller power-up or reset

D Preferred source loss and return

D Te s t

D Exercise

D Emergency source loss and return

The Sequence of Operation descriptions in Sections 2.2 through 2.4 describe the transfer switch normal operation for standard, programmed, and closed transition models. Operation can be affected by faults such as the normal or emergency contacts failing to open or close when signaled to do so.

2.1 Controller Power-up/Reset

Following is an explanation of the sequence of operation for the Decision-Makerr MPAC 1500 ATS Controller when power is initially applied to the controller or a controller reset occurs.

1. Controller self test is executed.

2. System parameters are downloaded from nonvolatile memory.

3. Contactor position and source availability are determined.

4. If neither source is acceptable, the contactor does not change p osition.

5. If both sources are available, the controller immediately transfers the contactor to the preferred source.

6. If only one source is available, the controller immediately transfers the contactor to that source, executing only the off-position and load control time delays.

If the available source is the preferred source, and the contactor is in the standby position, the contactor transfers to preferred, the engine cooldown time delay runs, and then the engine start contacts open.

If the available source is the preferred source and the contactor is already in the preferred position, the engine start contacts open immediately, bypassing the engine cooldown time delay.

2.2 Sequence of Operation, Standard Transition Models

2.2.2 Exerciser Operation, Standard Transition

Operation can be affected by faults such as the normal or emergency contacts failing to open or close when signaled to do so.

2.2.1 Preferred Source Loss and Return, Standard Transition

Following is an explanation of the transfer switch sequence of operation when Preferred Source failure is detected.

Preferred Source Fails

1. Load control contacts open.

2. Engine start time delay expires.

3. The generator is signaled to start.

4. The generator starts and the standby source becomes available.

5. Preferred-to-standby time delay expires.

6. Contactor transfers to standby.

7. Post-transfer load control sequences run.

Unloaded Exercise Sequence Starts

1. Exerciser timer begins.

2. The generator is signaled to start.

3. The generator starts and the standby source becomes available.

4. The load bank control is activated.

Unloaded Exercise Sequence Ends

1. The load bank control is deactivated.

2. Engine cooldown time delay expires.

3. The engine start contacts open, signaling the generator to stop.

Loaded Exercise Sequence Starts

1. Exerciser timer begins.

2. The generator is signaled to start.

3. The generator starts and the standby source becomes available.

8. Load control contacts close.

Preferred Source Returns

1. Standby-to-preferred and pre-transfer load control time delays expire.

2. Load control contacts open.

3. Contactor transfers to preferred source.

4. Post-transfer load control sequences and engine cooldown time delay expire.

5. Load control contacts close.

6. The engine start contacts open, signaling the generator to stop.

4. Preferred-to-standby time delay and pre-transfer load control sequences run.

5. Load control contacts open.

6. Contactor transfers to standby.

7. Post-transfer load control sequences run.

8. Load control contacts close.

Emergency Source Fails (Normal Source is available)

1. Exerciser is deactivated.

2. Load control contacts open.

3. Contactor immediately transfers to preferred.

4. Immediate failure to acquire standby alarm.

5. Post-transfer load control sequences and engine cooldown time delay expire.

6. Load control contacts close.

7. Engine start contacts open.
