5.  

Let the generator stabilize and warm up at no-
load for at least five minutes.

6.  

Set the generator's main circuit breaker (CB1) to 
its ON or CLOSED position.



7.  

With an accurate AC voltmeter and frequency 
meter, check the no-load, voltage and frequency.

 

Single-phase generator supply:

 

Measure across ATS terminal lugs E1 to E2. Also 
check E1 to NEUTRAL and E2 to NEUTRAL.

 a. Frequency 

....................................... 60-62 

Hertz

  b.  Terminals E1 to E2 ........................ 240-246 VAC
  c.  Terminals E1 to NEUTRAL ............. 120-123 VAC
  d.  Terminals E2 to NEUTRAL ............. 120-123 VAC

8.  Set the generator’s main circuit breaker (CB1) to 

its OFF or OPEN position.

9.  Set the AUTO/OFF/MANUAL switch to the OFF 

position to shut down the generator.

NOTE:

Do NOT proceed until generator AC output volt-
age and frequency are correct and within stated 
limits. If the no-load voltage is correct but no-
load frequency is incorrect, the engine governed 
speed probably requires adjustment. If no-load 
frequency is correct but voltage is not, the voltage 
regulator may require adjustment.

1.  Set the generator's main circuit breaker to its 

OFF or OPEN position.

2.  Manually actuate the transfer switch main con-

tacts to their EMERGENCY (STANDBY) position. 
Refer to the Manual Operation section.

3.  To start the generator, set the AUTO/OFF/MANUAL 

switch to MANUAL. When engine starts, let it sta-
bilize for a few minutes.

4.  Turn the generator's main circuit breaker to its 

ON or CLOSED position. The generator now pow-
ers all LOAD circuits. Check generator operation 
under load as follows:

 •   

Turn ON electrical loads to the full rated watt-
age/amperage capacity of the generator. DO 
NOT OVERLOAD.

 •   

With maximum rated load applied, check 
voltage and frequency across transfer switch 
terminals E1 and E2. Voltage should be 
greater than 230 volts and frequency should 
be greater than 59 Hertz.

 •   

Let the generator run under rated load for at 
least 30 minutes. With unit running, listen for 
unusual noises, vibration, overheating, etc., 
that might indicate a problem.

5.  

When checkout under load is complete, set main 
circuit breaker of the generator to its OFF or 
OPEN position.

6.  

Let the generator run at no-load for several min-
utes. Then, shut down by setting the AUTO/OFF/
MANUAL switch to its OFF position.

7.  

Move the switch's main contacts back to their 
UTILITY position. For example, load connected 
to UTILITY power supply. Refer to the Manual 
Operation section. Handle and operating lever of 
transfer switch should be in UP position.

8.  

Turn on the UTILITY power supply to transfer 
switch, using whatever means provided (such as 
a UTILITY main line circuit breaker). The UTIL-
ITY power source now powers the loads.

9.  Set the generator's AUTO/OFF/MANUAL switch to 

its AUTO position. The system is now set for fully 
automatic operation.
