• Maintain GPP settings from Procedure 6.
• Start the generator.
• Press foot switches.
• When the Red Light (See Fig. 7.1, A) is
illuminated, the “Current Meter” (See Fig. 7.1, B)
should show amperage and the “Seconds Counter”
(See Fig. 7.1, C) should be counting.
• If there is no display in the seconds counter,
replace the “N” cell batteries in the counter *(See
Fig. 7.2).
• Adjusting the “Percent of Range” (See Fig. 7.1, D)
up to 100% will increase the amperage shown on
the Current Meter.
• Set the “Percent of Range” to 50%.
• Switch the “Mode” switch (See Fig. 7.1, E) from
120 PPS to 60 PPS. The amperage should drop by
half.
CAUTION: Never switch the Voltage Range
while the output is ON.
• Retest settings in the high range.
NOTE: If output current is absent, return the
control box to Smith-Root, Inc.
* The “N” cell batteries should be replaced EVERY
ve years (See Fig. 7.2).
