What if my standby generator doesn’t transfer and/or generator light doesn’t come on?

Step 1. Verify if Utility Available Light is On

ATS MODEL	COMMAND	PASS	FAIL
WINCO	Not applicable: Go to Step 2
ASCO165 ASCO185	Start generator	Generator running, and generator available light is on: Go to Will Not Transfer troubleshooting steps Help Topic	Generator running, and the generator available light is off. Ensure plug is tight into the board: Go to Step 2

Step 2. Verify Generator Power At Switch

ATS MODEL	COMMAND	PASS	FAIL
WINCO ASCO165 ASCO185	Generator running > check L1-L2 voltage is 220-252 VAC on the alternate/generator source contactors of transfer switch	220-252 VAC: Go to Step 3	Not 220-252 VAC: Get generator power to the transfer switch. The breaker may be off or troubleshoot generator output voltage, wiring between generator and transfer switch

Step 3. Verify Switch Harness

ATS MODEL	COMMAND	PASS	FAIL
WINCO	Generator running and utility power off > check for voltage on Generator contact A1 and A2.	+/-120VAC. Replace generator contactor or coil	No Voltage. Trouble shoot harness/relay functions through the print. Once problem identified, restart test
ASCO165	Turn off generator with switch in Preferred position. Check continuity from L2 to pin 1 and 7 on Plug 1. Check continuity from L6 to pin 6 and Pin 16 on Plug 1. Ensure plug is tight on board	Harness continuity: Replace board	Poor connection/continuity: Troubleshoot harness and repair
ASCO185	Turn off generator with switch in Preferred position. Check continuity from L2 to pin 3 and 9 on Plug 1. Check continuity from L6 to pin 6 and Pin 10 on Plug 1. Ensure plug is tight on board	Harness continuity: Go to Step 4	Poor connection/ continuity: Troubleshoot harness and repair

Step 4. Verify Switch Settings

ATS MODEL	COMMAND	PASS	FAIL
WINCO ASCO165	Not applicable
ASCO185	Turn off all power in the switch. Check the following settings: Switch 1 actuator 4 = Off (Down) 60 hz Switch 2 actuator 2 = On (Up)	Match. Replace board	No Match. Adjust switches and restart at first step

What should I do if my standby generator doesn’t crank or generator cranks and doesn’t run?

Step 1. Verify Generator Will Start and Run Manually

ATS MODEL	COMMAND	PASS	FAIL
WINCO ASCO165 ASCO185	Controller > manual mode > start command	Generator starts & runs: go to step 2	Generator does start & run: repair symptom(s)

Step 2. Put Generator In Auto Mode

ATS MODEL	COMMAND	PASS	FAIL
WINCO ASCO165 ASCO185	Generator in Auto Mode > Jump Auto Start contacts to start in Auto Mode	Generator starts & runs: Go to Step 3	Generator does start & run: Repair symptom(s)

Step 3. Give Start Command From Transfer Switch

ATS MODEL	COMMAND	PASS	FAIL
WINCO	Flip toggle switch to start on the front pane	Generator starts & runs	Generator does not start & run: Troubleshoot the start switch continuity
ASCO165	Press & hold the push to test button until the generator cranks & starts	Generator starts & runs	Generator does not start & run: Go to Step 4
ASCO185	Press & hold the transfer test button for at least 15 seconds	Generator starts & runs	Generator does not start & run: Go to Step 4

Step 4. Start Command At Transfer Switch Fails

ATS MODEL	COMMAND	PASS	FAIL
WINCO	Manually bypass the switch start command & verify generator starts > Jump the Start Signal (#23) & Battery Negative (#1) terminals on the switch	Generator starts & runs: Go to Step 5	Generator does not start & run: Troubleshoot generator start circuit. Problem is in wiring between ATS and generator start contacts
ASCO165 2-Wire Switch	Manually send the start signal to the generator > Apply jumper to generator. Hold jumper for at least 20 seconds. Closed on start Jump Terminal Block 7 terminals 4 and 5. Open on start (not used w/Winco products) Terminal Block 7 terminals 5 and	Generator starts and runs: Go to Step 5	Generator does not start and run: Troubleshoot generator start circuit. Problem is in wiring between the ATS and generator start contacts
ASCO165 4-Wire Switch	Got to Step 5
ASCO185	Manually send start signal to generator > Apply jumper to generator. Hold jumper for at least 20 seconds. Closed on start Jump Terminal Block 7 terminals 4 and 5	Generator starts and runs: Go to Step 5	Generator does not start and run: Troubleshoot generator start circuit. Problem is in wiring between the ATS and generator start contacts

Step 5. Simulate Power Failure

ATS MODEL	COMMAND	PASS	FAIL
WINCO	Interrupt utility power to the transfer switch with the main switch in the Automatic position > ice cube relay should switch. You should open continuity between Start and Bat – terminals	Proper continuity between Start & Battery – terminals	Open continuity: Troubleshoot switch & relay wiring & function. Reset when finished
ASCO165 2-Wire Switch	Interrupt utility power to the transfer switch > start contact closed. Closed on Start = Continuity between terminal block 7 terminals 4 and 5 Open on start (not used w/Winco products) = No Continuity between Terminal Block 7 terminals 5 and 6	Proper continuity, generator starts and runs: Go to Step 6	Open continuity. If contact does not close when the utility available light goes out replace the ATS control board
ASCO165 4-Wire Switch	PART 1: Verify Voltages > Check voltage between Terminal Block 7 terminals 2(-) and terminals 3, 5 and 8 down. PART 2: Verify Crank and Run Signal > Interrupt utility/reset switch errors. Should have continuity between Terminal Block 7 terminals 7 and 8. Crank cycle is 10 seconds on/10 seconds off for three attempts. Should have continuity between Terminal Block 7 terminals 7 and 8.	Part 1: 12-15VDC: Continue to Part 2 PART 2: Generator starts and runs: Go to Step 6.	PART 1: Not VDC: Check generator battery, fuses and connections between switch and generator Part 2: No Run Signal and/or No Crank Signal: Replace ATS board.
ASCO185	Interrupt utility power to the transfer switch > this should close start contact Closed on Start = Continuity between terminal block 7 terminals 4 and 5 Open on start (not used w/Winco products) = No Continuity between Terminal Block 7 terminals 5 and 6	Proper continuity, generator starts and runs. Go to Step 6	Open continuity. If contact does not close when the utility available light goes out replace the ATS control board

Step 6. Reset System

ATS MODEL	COMMAND
WINCO ASCO165 ASCO185	Place transfer switch and generator in Auto Mode

Paving the Way – Phase 1

Posted on May 31, 2022June 6, 2022 by Josie — Leave a comment

As we continue to create generators that make your life easier, we also invest in our company to make it easier for our employees. We have started working on our parking lot. If you’ve visited us before, you probably thought, “They really need parking stripes!” You see, the parking lot has become half gravel and half pavement. It is very uncomfortable on my paws when I have to walk across it to get to the grass.

Phase 1: Sidewalks

We added sidewalks and an outdoor break area around the building.

Stay tuned for Phase 2!

Prime Power in Gasoline

Posted on May 27, 2022June 13, 2022 by Josie — Leave a comment

We have always built great commercial grade portable generators fueled by gasoline. Currently our air-cooled models can supply up to 19kw in both single and three phase voltages. We regularly get asked for more power and engines that last longer and run 1800 rpm.

When we say we listen, we mean it. We are excited to add to our liquid-cooled family of generators a gasoline, prime-power certified option. Our new PPG28 provides 30% more power than our biggest air-cooled generators. Operating at 1800 RPM it is a great investment for for commercial users that need a serious generator to keep their business running. Check out the table below for reasons you should consider the new PPG28 for your business.

PPG28
