With the engine running smoothly, check the no load 

voltage and frequency at wire #  and # 4 (L2 and 

L6 in the ASCO ATS) on the generator terminal block 

in the ATS.  The voltage should be 240 volts plus or 

minus nominal.  The frequency should be between 

6.5 to 62 hertz (Hz).  The voltage should also be 

checked between the hot terminals (L2 and L6) and 

the neutral to be certain of a balanced voltage output 

and a solid neutral connection.  The voltage should 

be about on half of the line to line voltage.

**  NOTICE  **

If for any reason during the check out procedures 

the voltage and frequency are not correct, move the 

toggle switch to the “STOP” position and correct the 

trouble before proceeding.

After verifying the voltage and frequency are cor-

rect, move the right hand toggle switch to the AUTO 

position.  The unit should shut off with no time delay.  

The right hand toggle switch must be left in the 

AUTO position for proper operation of the gen-

erator.  

If you leave it in the RUN position the fuel 

solenoid will remain open and it will not shutdown 

properly after the next exercise period.

Transfer Switch & Engine Generator

This procedure checks the electrical operation of 

the automatic transfer switch.  If the actual operation 

does not follow this procedure, consult the trou-

blshooting section in the transfer switch manual.

    .  Move the left hand toggle switch from the OFF 

position to the ON position.  The alarm light should 

go out.  The unit is now ready to be operated from 

the Automatic Transfer Switch.

*****  WARNING  *****

     ******************

PERSONAL INJURY HAZARD - Install front cover 

in transfer switch before operation.  An electrical sys-

tem fault could cause a flash and severe personal 

injury.

    

2.  Turn on the preferred source (utility) circuit 

breaker.  The utility source acceptable light should 

now come on as well as the transfer switch on utility 

light.  If these lights fail to come on recheck your 

incoming power to insure you have 240 volts nomi-

nal.  If not, troubleshoot your utility source before 

continuing.

    3.  Turn on the altenate source (generator) curcuit 

breaker.

There are two ways to test your transfer switch 

operation:  WITHOUT a load transfer or WITH a 

load transfer.

WITHOUT load transfer (normal exercise)

    .  Press and release the 

Push to Test 

button.  

The generator set should start immediately.  About 

5 seconds the generator (alternate source) accept-

able light comes on and stays on.  

    2.  The generator set runs for 20 minutes.  The 

Transfer Switch does not transfer the load to the 

generator set. The 

Transfer Switch
