is intended as an emergency
backup system only, and is not intended as a substitute for
operator diligence during the loading process.
The operation of the SpillStop during the loading operation is as
follows: When the tank is empty, the green TANK EMPTY indicator
is on, the horn is off, and the engine is allowed to run. As the
fluid level rises, the empty indicator goes out. When the horn
alarm point is reached, the yellow HORN ALARM indicator comes
on and the horn is activated with a 0.5 second on, 0.5 second
off cycle. Depressing the horn alarm BYPASS at this point will
silence the horn. If the fluid level continues to rise and reaches
the engine shutdown point, the red SHUTDOWN indicator will
come on, the green ENGINE ON indicator will go out, and the
truck engine will be shut off. Depressing the shutdown BYPASS
at this point will re-light the ENGINE ON indicator and allow the
engine to be restarted. When a BYPASS switch is depressed, the
alarm indicator stays on and the red bypass indicator comes on.
As the tank is unloaded the alarm indicators will go out when the
fluid level drops below the alarm points, and the bypasses will be
cleared (the system is re-armed) when the TANK EMPTY indicator
comes back on. There is no need for the operator to re-arm the
system, removing the possible operator error of forgetting to re-
arm. If the tank is not filled to the alarm point, the system can
still be bypassed to prevent sloshing from sounding the horn or
shutting down the engine during driving. If a single tank is to be
filled from more than one location, the alarms can be bypassed
during driving between loading sites, and the system re-armed
with the MANUAL RE-ARM switch to re-establish spill protection
for the second load.
The SpillStop has a number of convenience and safety features
built into the system. When the tank is empty, the bypasses will
not work, preventing accidental bypassing when the driver is
leaving the cab to begin loading. Delays are incorporated into the
system to prevent noise spikes or momentary bad connections
from disrupting operation. A short circuit in the wiring to the
gauge, or plugging the SpillStop plug into the trailer lighting
socket, lights the red SHORT CIRCUIT indicator and shuts down
the engine. An open circuit in the wiring to the gauge, or a
disconnection of the plug to the trailer, lights the red UNPLUGGED
indicator, sounds the horn, and shuts down the engine. These
alarms can be bypassed to allow operating the tractor without the
trailer connected. The pulse signal between the gauge and the
controller cannot be corrupted by poor connections or moisture in
the wiring; if the signal is too badly degraded it defaults directly to
an open or short circuit condition. A failure of the SeeLeveL gauge
defaults to the engine shutdown alarm condition. The gauge and
