1.10 VOLTAGE REGULATOR
ADJUSTMENT
With the frequency between 61-62 Hertz, slowly turn
the slotted potentiometer (Figure 1.4) until line volt-
age reads 244-252 volts.
NOTE:
You must remove the roof to adjust the voltage
regulator.
Figure 1.4 – Voltage Adjustment Potentiometer
NOTE:
The voltage regulator is housed in the generator's
control
panel.
The
regulator
maintains
a voltage in direct proportion to frequency at a 2-
to-1 ratio. For example, at 62 Hertz, line-to-neu-
tral voltage will be 124 volts.
1.11 ADDITIONAL GENERATOR
FEATURES
1.11.1 8 KW AND 10 KW UNITS
The 8 kW and 10 kW air-cooled Guardians offer addi-
tional features that are not factory preset:
1.
Remote Start – This allows for remote starting of
the generator by means of the #183 (common)
and
#178
(normally
open)
lines
with
the
Auto/Off/Manual switch set to AUTO. Closure of
the circuit starts the unit; opening of the circuit
stops the unit. See Figure 1.5.
NOTE:
This function will work only with the unit in the
AUTO mode.
Figure 1.5 – Remote Start/Alarm Options
–Type 14 AWG wire is recommended.
–These options should be wired to the unit by a qualified electrician or
Generac/Guardian Authorized Dealer.
2.
Remote/Common Alarm – This allows for an
alarm, light, horn, etc., to activate when any fault
has occurred. Lines #210 (common) and #211
(normally open) provide a “closure” on common
fault, which can be used for 120 volts, 10 amps
maximum. See Figure 1.5.
3.
Remote Not Auto – The generator will not auto-
matically start during a utility failure.
