Testing Engine Speed at the GFCI Receptacle.
WARNING: Dangerous voltage and/or current may be present when a
voltage test is being conducted. To reduce risk of serious injury or death from electrical
shock, if you are not trained to safely work with high voltage, do not attempt any of these
procedures. You must seek assistance from qualified personnel.
The speed of the engine may be tested by using a multimeter with the scale set to read
hertz.
NOTE: Not all multimeters have Hertz scale.
Set your multimeter to the Hertz ( H
z
) scale. While the engine is running and the light
breakers turned off, insert your meter probes into the GFCI receptacle as shown in
figure N.1
( Pg. 14). The meter should read 62.0 Hertz with no load on the engine. A
reading of less than 62.0 Hertz indicates that the engine is not running with enough
speed to create the necessary power to operate all of the lamps consistently.
Slow engine speed may be caused by a number of factors:
A. Incorrectly adjusted engine governor. Adjust governor as shown on the following
page ( Figure D.1/Pg 15 ) until a reading of 62.0 H
z
is indicated on the multimeter
display.
B. Clogged or dirty air and or/fuel filters. Replace filters if there are any questions as
to their condition.
C. Dirty fuel. Drain fuel tank and fuel system and replace with known clean fuel.
Replace fuel filter before re-starting the engine.
D. Worn or damaged engine. If the above steps fail to correct the engine speed this
may indicate a faulty engine. Contact your local servicing dealer for the make
and model diesel engine in your light tower. Repair, build or replace as
necessary.
Note: Many Allmand light towers designed for use outside of North America operate at
230 Volt + 10%s/ 50Hz. Engines on these models must be set for 52.0 Hz at no load per
the above instructions. If you are unsure which voltage your light tower is designed to
produce, contact a qualified electrician for assistance.
