JIG Bulletin 58 - January 2013
C&L Sales & Services P/L

2. JIG Bulletin 58 - Requirements
The 10 commandments
Filter monitors shall never be operated above a differential pressure of 22 psi
A dP switch shall be installed to activate if a high dP (22 psi) is encountered
A dP switch shall be connected in parallel with the dP gauge and linked to the deadman and fuelling control system
The dP switch shall be set to 22 psi and designed to automatically stop the fuelling operation

3. JIG Bulletin 58 - Requirements
The 10 commandments
The system shall not be capable of being reset by the fuelling operator
The system shall be installed so that the deadman override does not reset and reactivate the system.
The system shall also be fitted with a mechanism (eg. a key operated device) to reset the dP switch after installing new filter elements or following dP gauge free movement tests

4. JIG Bulletin 58 - Requirements
The 10 commandments
All dP switches shall meet the hazardous area classification for the installed location
Fuel-wetted parts shall be stainless steel with elastomers manufactured from Buna N, Viton or as recommended by the manufacturer

5. JIG Bulletin 58 - Requirements
The 10 commandments
The function of the dP switch shall be checked to ensure that the fuelling operation would be stopped when a pressure of 22 psi is applied to the dP switch.

6. JIG Bulletin 58 - Requirements
The 10 commandments
The function of the dP switch shall be checked to ensure that the fuelling operation would be stopped when a pressure of 22 psi is applied to the dP switch. This check shall be performed and recorded every six months and can be performed during the dP gauge free movement check. Piston-type differential pressure gauges shall be checked for free movement throughout the full piston travel and visually for correct zeroing. This shall be done every 6 months. (JIG 1, )

7. JIG Bulletin 58 - Requirements
The 10 commandments + 1
All existing hydrant servicers that have filter monitor vessels shall have a dP switching device installed by December 31st 2013

9. CL-A-J58-KIT (dP) Differential Pressure Control System
The CL-A-J58-KIT meets or exceeds ALL requirements as outlined above & required by JIG.

10. CL-A-J58-KIT (dP) Differential Pressure Control System
Fits any refuelling vehicle that use a deadman system being air or electric
Fits all and every refuelling vehicle across the globe. Any manufacturer
No changes necessary to existing PLC systems (if fitted)
No changes necessary to any other on board logic systems

11. CL-A-J58-KIT (dP) Differential Pressure Control System
Full compliance with JIG 1, which states “Piston-type differential pressure gauges shall be checked for free movement throughout the full piston travel and visually for correct zeroing
The manufacturer’s requirement for calibration / checking the dP gauge is to carry out a full piston deflection test

12. CL-A-J58-KIT (dP) Differential Pressure Control System
Most components in the
kit are fitted safe, secure & neatly inside the J-Box.
The J-Box must be fitted inside the vehicles cabin
Gammon dP gauge shown c/w switch & deflection test button. Switch mounts on right or left side

13. CL-A-J58-KIT (dP) Differential Pressure Control System
The J-Box comes complete with wiring diagram and simple installation instructions
(supplied on purchase)

14. CL-A-J58-KIT (dP) Differential Pressure Control System
CL-A-J58-KIT - Feature List
Compact
Failsafe in operation
Allows the operator to carry out a dP gauge full deflection tests using the supplied “test /over-ride” button
The test/over-ride button
Cannot be jammed or used as not intended
Repeated depressions (3 times within 30 seconds) disables button for a further 10* minutes
Test mode operates for 10 seconds only
As required by JIG

15. CL-A-J58-KIT (dP) Differential Pressure Control System
CL-A-J58-KIT - Feature List
LED warning light. Standard fit is on the J-Box but it can be mounted on the operating panel or elsewhere in cab
If activated the system goes into “lockout” mode and can ONLY be reset by use of the supervisors key. This switch is fitted directly to the J-Box (as shown)
Lockout mode CANNOT be reset by cycling of the battery master switch. The key must be used.
Suitable for air & electric deadman systems.

16. CL-A-J58-KIT (dP) Differential Pressure Control System
CL-A-J58-KIT - Feature List
Meets of exceeds “class 1, division 2” approvals (equal to all existing dP switches, currently fitted)
To meet the requirements of “Class 1, Zone 2” a barrier is required (optional) and would be fitted within the J-Box
All items are clearly labelled.
The CL-A-J58-KIT controls air, electric and and also auxiliary deadman systems

17. CL-A-J58-KIT (dP) Differential Pressure Control System
CL-A-J58-KIT – COSTS - Per Vehicle – Considerations
Total price is dependant on the make of your dP gauge being Alfons Haar or Gammon
If your dP Gauge is neither of the above, we suggest changing the dP gauge. *We supply & fit either
See our spread sheet online at

18. CL-A-J58-KIT (dP) Differential Pressure Control System
CL-A-J58-KIT – COST - Optional
Gammon dP Conversion Kit
Warning light, fitted outside of cabin
Gammon Gauge c/w dP switch and dP test button
Air/electric (ex) solenoid. For air deadman/air over-ride systems
Class 1, Zone 2 electrical barrier (*ask)
Alfons Haar dP switch (ex or other)
