 |
Single
compartment version of the Model 815 SpillStop
in an inside/outside mountable housing. |
 |
|
|
|
|
Optional instrument for the Garnet SeeLeveL
family of truck gauges. |
 |
Provides automated control of PTO driven pumps for
spill prevention during loading.
|
|
Uses SeeLeveL alarm points to provide a warning horn
and an engine or hydraulic pump shutdown.
|
|
Bypass feature silences the warning horn and allows
engine restart.
|
|
The bypass is automatically cancelled during off
loading to remove the human factor (the operator is
not required to re-arm the system to maintain spill
protection).
|
|
Manual re-arm (to cancel the bypass) maintains spill
protection for partial loads.
|
|
Panel indicators display the load status.
|
|
The controller can be mounted inside or outside the
cab.
|
|
Designed for both body trucks and tractor trailer
units.
|
|
The tractor-trailer interconnect plug is monitored to
detect plug swapping, faults, and disconnection.
|
|
The wiring from the controller to the gauge is
monitored for open and short circuits.
|
|
Operation from -40 to +60 oF (-40 to +140 oF)
ambient temperature.
|
|
Easy installation and servicing.
|
|
One year limited warranty.

The SpillStop consists of two main components: the
controller on the truck, and the gauge module inside
the SeeLeveL truck gauge. The optional plug module
inside the 7 pin socket housing is for tractor trailer
applications.
|
|
The gauge module installs inside the Model 810PS
SeeLeveL gauge display, and converts the alarm signals
from alarms 1, 2, and 3 in the gauge to a pulse signal
which is sent along a single wire to the controller.
The Model 808PA SeeLeveL Special gauge display has the
gauge module built in.
|
|
The plug module monitors the signal between the gauge
module and the controller and turns on the SpillStop
indicator only if the 7 pin plug is connected and the
signal is getting from the gauge to the controller.
The module is only needed for tractor-trailers
combinations where the signal must go through a plug
and socket, it is not necessary for body trucks.
|
|
The controller monitors and displays the alarm status
of the gauge, activates a horn if the fluid level in
the truck tank is at the full point, and shuts off the
vehicle engine, pump engine, or hydraulic pump if a
spill is imminent.
|
|
The operation of the SpillStop during the loading
operation is as follows: When the tank is empty, the
green EMPTY RE-ARM indicator is on, the horn is off,
and the engine or pump 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
shut down point, the red SHUT DOWN indicator will come
on and the engine or hydraulic pump will be shut
off.
Depressing the shut down BYPASS at this point will
allow the engine or pump 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 cancelled (the system is re-armed)
when the EMPTY RE-ARM 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 the tank is to be filled from more
than one location, the alarms can be bypassed for the
drive between loading sites, and the system manually
re-armed by pressing both BYPASS switches
simultaneously to re-establish spill protection for
the second load.
|
|
Some of the other safety features of the system are as
follows: When the tank is empty, the bypasses will not
work, preventing accidental bypassing prior to
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 or pump. 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
or pump.
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 wiring 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 shutdown alarm condition. The gauge and plug
modules cannot be damaged by short circuits or by
plugging the trailer light plug into the SpillStop
socket. The controller will operate at truck voltages
from 8 to 16 volts.
|
|
Installation is straight forward, as indicated by the
drawing. The only wiring required is a single wire
from the socket to the gauge, a standard 7 wire cable
from the tractor to the trailer, 12 volts to the
controller, and controller connections to the electric
horn and engine/pump shutoff. The system draws less
than 1/8 amp so it can operate from any convenient
circuit.
