THERMAL SENTRY
t
INDICATOR
The Thermal Sentry
t
indicator
glows when
there is excessive heat, possibly from a fire, in the
hopper. It will stop the vacuum fan and main brush
from operating. The Thermal Sentry
t
must be
manually reset. See
THERMAL SENTRY
t
in the
MAINTENANCE
section.
BATTERY CONDITION INDICATOR
The battery condition indicator
glows when the
present voltage potential of the battery is not normal
--- 10 to 14 volts. Also when the engine is operating,
the indicator glows when the alternator output
voltage falls below 10 volts or when it exceeds 14
volts. If the voltage falls below
10 volts, it may not
be accepting or getting a charge from the alternator.
If the voltage exceeds 14 volts, it may be
overcharging. Undercharging and overcharging are
indications that one or more electrical components
are in need of repair.
HYDRAULIC FLUID TEMPERATURE INDICATOR
The hydraulic fluid temperature indicator
glows
when the temperature of the hydraulic fluid in the
reservoir exceeds 225
_
F (107
_
C). When the
indicator glows, an audio alarm will sound for
30 seconds and then the engine will stop. The
engine may be restarted --- the alarm may still sound.
If it does, you will have another
30 seconds before the engine stops. Locate and
correct the problem.
ENGINE COOLANT TEMPERATURE INDICATOR
The engine coolant temperature indicator
glows when the temperature of the engine
coolant exceeds 225
_
F (107
_
C). When the
indicator glows, an audio alarm will sound for
30 seconds and then the engine will stop. The
engine may be restarted --- the alarm may still sound.
If it does, you will have another
30 seconds before the engine stops. Locate and
correct the problem.
An over-heating condition may arise due to a low
coolant level, a clogged radiator, a loose fan belt, a
defective thermostat, or other engine malfunctions.
Engine over-heating will always cause a coolant loss.
If coolant loss does not occur, check for malfunction
of the temperature sending unit.
