ST–47 Groundhog
Vehicle Static Grounding System
Featuring Dynacheck® – Automatic and Continuous Self-Checking Circuitry
DESCRIPTION
Don’t let unsure grounding methods leave you guessing. Transport vehicles should be properly tied to ground before and during the loading operation. There should never be any doubt that the grounding systems at your terminals are performing their proper function. Many systems give you little assurance of their operation. The Scully Groundhog gives you complete assurance that a proper static ground tie-in is present.
The Groundhog is a self-proving grounding system for maximum safety in loading operations. It can operate in conjunction with your existing Scully Overll Prevention System or as an independent unit.
Scully Signal Company has over 30 years of electronic liquid handling experience providing the ultimate dependability, service and safety.
The Scully Groundhog grounding system can be used for a wide variety of loading applications for use with tank trucks, rail cars, and aircraft refuelers.
FEATURES AND BENEFITS
- Self-Proving, the Groundhog continuously monitors the grounding connection throughout the loading operation.
- Can be used in conjunction with your Scully Overll Prevention System offering one quick connection for overll protection and grounding verication.
- Can also be used as a completely independent grounding system with a special quick-release plug for grounding to a specially designed, vehicle mounted, electronic ball.
- Direct earthing tie point at loading rack available.
- Immediately shuts down the loading operation if proper static grounding is not present.
- FM approved
- No manual checks are needed.
IMPORTANT
Static grounding is used to dissipate any static charges which can build up as a result of product ow or other movement. Some applications such as rail lines and pipelines may also have stray currents present. In these situations the rail or pipeline must be bonded to ground independently from the Scully system. Local codes should be consulted regarding wire gauges and number of conductors.
Scully Ground Bolt
THE SCULLY GROUNDHOG PROVES IT
The Scully Groundhog gives you complete assurance that grounding to the vehicle’s frame has been accomplished. The Groundhog is an intelligent system which continuously and automatically monitors the grounding connection during the entire loading operation.
The Groundhog is designed to immediately shut down the loading operation if the earth tie-in is broken. That’s proof-positive, something no other system can provide.
The Groundhog control monitor is mounted at the loading rack.Indicator lights on the face of the control monitor are visual proof that proper grounding has been accomplished.
The Groundhog requires that each vehicle be equipped with a specially designed Scully electronic ground ball or bolt. Before the loading operation can begin, the controller must see an intelligent return signal from the ground ball or bolt, indicating that a proper grounding connection has been made.
ARE YOUR GROUNDING SYSTEM OPTIONS LIMITED?
The Groundhog Control Unit can be wired into your existing Scully Overfill Prevention System for the ultimate safety system. Just one connection gives you overfill and grounding protection. This single connection simplies loading and eliminates the need for additional plugs and cables at the loading rack.
The Groundhog utilizes a separate conductor in the existing Scully Overfill Prevention Plug and Cable together with a special Scully Ground Bolt mounted on each vehicle. The Scully Ground Bolt’s sensing lead is wired to the Scully Overfill Prevention Socket.
Only Scully offers you a complete, integrated overfill prevention and vehicle grounding system for maximum safety in your loading operations.
CONTROL UNITS AND PLUG AND CABLE ASSEMBLY
If you intend to wire the Groundhog in conjunction with your existing Scully Overfill Prevention System, you need only order the control monitor. For the independent system, order the control monitor and junction box with plug and cable.
ORDERING INFORMATION
Vehicle Static Grounding System
DON’T USE A SYSTEM THAT IS EASILY CHEATED
There are many systems that claim to be foolproof and even self-checking. It is possible with many of these systems to bypass a safe earth tie-in by attaching the clamp to the rack, a metal shim or by jumping the plug contacts with a paper clip. In many cases, there is no proof that proper earthing has been made or that the system is functioning correctly.
The Scully Groundhog when used together with a Scully Ground Ball or Ground Bolt, foils these typical cheating methods and malfunctions that can lead to grounding vehicles improperly.
The Scully Grounding System ensures that unless the proper grounding connection has been made, the loading process will not begin. It will automatically shut down the loading operation if the ground is broken. The Groundhog’s intelligent monitoring capabilities and the special electronic circuitry inside the Scully Ground Ball and Ground Bolt form a self-proving system. No manual checks are needed.
Only the Scully Groundhog can provide you with the safest and most dependable means for vehicle static grounding. It maintains the integrity of your loading operation.
SCULLY HAS A SYSTEM FOR EVERY APPLICATION
The Groundhog can be used as a completely independent system. This system is ideal for top loading or applications where a Scully Overll Prevention System is not in use.
The control monitor connects to a heavy duty Sculcon® junction box with attached cable and special quick release snap-on plug. The Scully Ground Plug connects to a specially designed electronic Scully Ground Ball mounted on each vehicle. The controller in conjunction with the ground ball provides and verifies vehicle grounding before loading can begin. The controller must receive an electronic return signal from the ground ball throughout the loading operation.

Ground Verication Clamp and Cable Unit
For use with Sculcon Junction Box, Model SC-47CC/CLMP
Featuring Dynacheck® – Automatic and Continuous Self-Checking Circuitry
DESCRIPTION
The Scully SC-47CC/CLMP Clamp and Cable Unit is designed to drain static charges built up on vehicles, railcars and other metal liquid tank containers. The clamp unit is designed to be connected, via two wires, to the Scully Groundhog™ grounding verification system. When the clamp is attached to bare metal on the tank container, the system utilizes an intrinsically safe signal to verify that a proper static bond exists during liquid transfer operations.*
Static grounding is used to dissipate any static charges which can build up as a result of product ow or other movement. Some applications such as rail lines and pipelines may also have stray currents present. In these situations the rail or pipeline must be bonded to ground independently from the Scully system. Local codes should be consulted regarding wire gauges and number of conductors.
If the clamp is not properly attached to the tank vehicle, the system will not allow product to transfer. If at any time during the transfer process the clamp is disconnected, the system will send a signal to stop the product transfer.
The clamp and cable unit is connected to a heavy duty, weatherproof junction box. The junction box acts as a housing to connect the cable wires and the controller wiring. In the event of a drive-away, the cable pulls out of the junction box. This maintains vapor tight safety and prevents damage at the control monitor. Other systems without a junction box disconnect and may allow non-intrinsically safe signals within the liquid transfer environment during a drive-away accident.
FEATURES AND BENEFITS
- Verification of static grounding when properly connected to the trailer frame.
- Intrinsically safe operation.
- Spring-loaded clamp jaws with adjustable contact pins for a solid bond to the trailer frame.
- Heavy-duty, weather-sealed aluminum junction box to house cable wiring.
- The clamp and cable disconnects from the junction box during a drive-away accident, preventing damage to the control monitor and maintaining intrinsic safety.
*WARNING
When used in conjunction with a Scully Groundhog, the clamp provides a resistance (non self-proving) verication system. Thus, attaching the clamp to a metallic object or to a vehicle, which already has a return path to ground, could give a permissive indication through this alternate path, which may not include the vehicle. To ensure self proving operation, the vehicle must be equipped with a Groundbolt or Groundball.
