The words “Earth” and “Ground” have the same meaning when used within this manual.

The Earth-Rite II system can be powered from a range of supply voltages dependent upon the model. Take care to select the correct terminals to connect the supply wires to.

The system should be connected as per the enclosed installation drawings and instructions.

Earth-Rite II RTR P1 STATIC EARTH MONITORING SYSTEM

The Earth-Rite II RTR system operates using “Tri-Mode” technology which uses the electrical capacitance of the tank truck (road tanker) to ensure the presence of an affective Static Ground Point to which the tank truck is connected. It also monitors that the clamp is connected to a tank truck rather than directly to grounded structures or isolated items of metal. Once permissive, the system continues to monitor the resistive loop circuit from tanker to the Customer’s Ground Bus.

For correct operation the cables connecting the Junction Box to the Monitoring Unit should be no more than 10 ft (3 m) in length. This length is restricted to 3ft (1m) if metal conduit is used.

Maintenance: Periodically check exterior of enclosure for damage or deterioration.

Junction Box

When using flexible/intrinsically safe cable, utilize the Compression Gland for cable entry into the Junction Box – alternatively if using sealed/rigid conduit, take out and discard the cable gland, drill out and fit a suitable ¾” NPT conduit entry fitting.


A - the presence of a tank truck*,

It should be noted that items other than tank truck may cause the system to go permissive if the object displays a capacitance, with respect to ground, which is in the order of that exhibited by a tank truck.

Tri-Mode system (capacitance and resistance monitoring), it is intended for use with tank trucks. It is set to show permissive only when the system detects:

A device known as the RTR Tester is available to allow the Earth-Rite II RTR to switch to permissive, for test purposes, when a tank truck is not present.

Attaching the RTR Grounding Clamp to the tank truck before anything else will ensure correct operation of the system.

IF YOU HAVE ANY QUERIES REGARDING THE ABOVE POINTS THEN PLEASE CONTACT NEWSON GALE, OR THEIR APPROVED DISTRIBUTOR, WITHOUT DELAY.

C - that the connection to the Customer’s Ground Bus is less than 10 Ohms nominal resistance.

The RTR system may be used with the Newson Gale Mode Selector Key Switch. The switch enables the system to be switched from Tri-Mode operation to Single-Mode operation.

* The circuit measures the capacitance of the tank truck with respect to ground. The tank truck must be isolated from ground prior to fitting the grounding clamp in order for the RTR system to measure the value of capacitance between the tank truck and ground. If the value of capacitance is too low the system will not recognise the tank truck.

B - the presence of a connection to Ground, and

Single-Mode operation, resistive only, is intended for use with any conductive metal item such as a drum, mixing vessel, rail tanker etc. It is set to show permissive only when the system detects that the connection to the plant item, and to the Customer’s Ground Bus is less than 10 Ohms nominal resistance. Until this condition is achieved, the system remains non-permissive.

Until these conditions have been met, the system will remain non-permissive.

Advanced Safety Feature

The following procedure will ensure that the system can safely continue to monitor the clamp connection following a Power Outage situation:

The Earth-Rite II RTR has a System Reboot facility in response to Power Outages. This safety feature is designed to maintain high site safety during interlocked transfer operations using hoses. Should the mains supply be lost during the transfer process, the system will become non-permissive and the transfer operation will stop.

4 Turn ON the supply to the ERII system.

The benefits of the System Reboot facility also apply to the situation where the clamp is accidentally removed during the transfer process and the system goes non-permissive. If this happens, the above procedure should be used to allow the transfer operation to continue safely.

The system should become permissive as indicated by the green flashing LEDs.
