815-UDHP/H SpillStop Ultra™ Dual Hose Protection Overfill Prevention System – Hydraulic Pump Version
The 815-UDHP SpillStop Ultra™ Dual Hose Protection Alarm Controller represents the state of the art in spill control for crude oil and chemical hauling.
The 815-UDHP SpillStop Ultra™ Dual Hose Protection Alarm Controller (Hydraulic Pump Version) works in conjunction with two Model 808-P2 SeeLeveL Special™ or Model 810-PS2 SeeLeveL ProSeries II™ systems to assist the truck operator with truck tank overfill protection in applications where the fluid is loaded with a hydraulic pump. The 815-UDHP also prevents spills and damage due to blown hoses by shutting downloading if excessive hose pressure is detected.
- Provides automated control of hydraulic pumps for spill prevention during loading
- Dual compartment model uses alarm points from two SeeLeveL™ gauges to provide a warning horn and a hydraulic pump shutdown
- Prevents spills and damage due to blown hoses by shutting down loading if excessive hose pressure is detected
- Optional pump direction sensor allows unloading regardless of tank level
- An individual bypass per compartment silences the warning horn and permits pump restart to allow hose cleanout without risking tank overfill
- The bypasses are automatically cancelled during off loading to remove the human factor so the operator is not required to re-arm the system to maintain spill protection
- Front panel LEDs display complete operational status
- The wiring from the gauge to the controller is monitored for open and short circuits
- Weatherproof display enclosure for exterior mounting on tank trailer
- Operation from -40 to +60 °C (-40 to +140 °F) ambient temperature
- Easy installation and servicing
- One year limited warranty
The hydraulic pump will not run if the SpillStop is not powered on. During loading, if there is a closed valve on the discharge side of the pump, the excessive hose pressure will be detected and will cause an immediate pump shutdown. This prevents damage and spills due to blown off hoses. When a float reaches the HORN alarm point, the horn will sound and the pump will shut down. Pressing the BYPASS button for that compartment on the SpillStop will turn off the horn and allow the pump to restart, allowing the operator to clean out hoses. If loading is continued to the point that the SHUT DOWN alarm point is reached, the pump will again shut down. There is no bypass button for this condition so it is not possible to load higher than this point due to the risk of an overfill spill. If the system is equipped with the optional pump direction sensor, the pump can be restarted for unloading only. If there is a valve closed on the discharge of the pump for unloading then the pump will shut down just like during loading. When loading is complete, the system can be powered off to deactivate the horn. This prevents sloshing or any faults from sounding the horn during driving.
Both bypasses will be cleared whenever the tank is unloaded or the system is powered on. This automatic feature means that there is no need for the operator to remember to re-arm the system. During all phases of operation the status of the alarms, valve or wiring faults, bypass, and pump permission are shown on the front panel LED indicators.
Installation is straight forward. The system draws less than 1/8 amp so it can operate from any convenient 12 volt circuit.
When the tank level is below the HORN alarm point, the bypass will not work, preventing accidental bypassing below the alarm point. Delays are incorporated into the system to prevent electrical noise or momentary bad connections from disrupting operation. A short circuit in the wiring to a gauge lights the red SHORT CIRCUIT indicator and shuts down the pump. An open circuit in the wiring to a gauge lights the red UNPLUGGED indicator, sounds the horn, and shuts down the pump. The horn sounding can be bypassed but these shutdowns cannot be bypassed. The pulse signals between the gauges and the controller cannot be corrupted by poor connections or moisture in a wiring, if the signal is too badly degraded it defaults directly to an open or short circuit condition. A failure of a SeeLeveL or SeeLeveL Special gauge also causes the SpillStop to default to a shutdown condition. The controller will operate at truck voltages from 8 to 16 volts.
