OPERATION
TESTING 240VAC SINGLE PHASE
2-1 SETTING UP THE LOAD BANK - Place the load bank in an area free from fuel, oil, or any other
flammable substance. The load bank should be positioned so that any strong wind or air currents will
flow with the air flow of the load bank.
2-2 APPLYING POWER - The load bank should be connected to the power unit to be tested with an
output of 240VAC single phase. Make sure that the power unit is off before connecting the cable to the
load bank. Use L1, L2 and N, the blue and yellow plug, when testing 240VAC single phase circuits. Plug
the power cable plug in to the load bank. MAKE SURE THE COPPER LUG ON L3 IS INSULATED.
Turn on the output of the power unit. If the HI-VOLTAGE light comes on, push the High Voltage reset
button if the meter shows 120VAC or less. If the voltage is above 120VAC, turn off the power being
tested and fix the high voltage problem, before using the load bank.
2-3 CHECKING THE POWER - check the following:
A.
The amber light, “A” and “B” should be on.
B. The voltmeter should read 120VAC on
“A” and “B” phase.
C. The frequency meter should read approximately 60HZ.
D. The ammeter should read 0A.
E. The HI-VOLTAGE light should be off.
2-4 APPLYING THE LOAD - If the above steps checked OK, turn on the main switch. The fans should
start up and the airflow should be as indicated by the airflow arrow. Add the load desired with the rate
switch.
A. Step 1 is 3.33KW
B. Step 2 is 6.66KW
C. Step 3 is 13.33KW
D. Step 4 is 20KW
E. Rotary Rate Switch 0-3.33KW
Check to see that the voltage and frequency does not drop beyond acceptable limits under load. Return
the rate switch to the off position.
2-5 SHUTTING DOWN - After turning the rate off, allow the load bank to cool down before turning the
power unit off. Turn the power unit off and disconnect the power cable plug.
