ELECTRONIC GROUNDING SYSTEM EJB../KTM

Product catalog summary

Specifications:
The document describes two electronic grounding systems, EJB-A/KTM and EJB-B/KTM, designed for dispersing electrostatic charges during loading and unloading operations of tank trucks. These systems are suitable for use in hazardous zones 1, 21, 2, and 22, with temperature ratings of T6 and T85°C respectively. The devices operate at an input voltage of 230V with a rated current of 28 mA and a power factor of 0.8. The EJB-A/KTM model includes one clamp, while the EJB-B/KTM model includes two clamps.

Procedures:
The grounding systems function by connecting clamps to conductive parts of the tank truck. The electronic unit verifies the ground resistance, and if acceptable, enables the grounding and switches the SPDT contacts to control the tanker's pump, indicated by a green light. For the EJB-B/KTM model, both clamps must pass resistance verification for the system to activate.

Materials:
The devices are constructed with a body and cover made from low copper content aluminum alloy, stainless steel cover bolts, and nickel-plated brass cable glands. They feature an internal electronic earthing system and are coated with anti-condensation internal coating and Ral 7040 polyester.

Key Features:
- EJB-A/KTM: Single clamp system
- EJB-B/KTM: Dual clamp system
- Operates in hazardous zones with specific temperature ratings
- Ensures safe dissipation of electrostatic charges
- Constructed with durable materials for reliability

DISPOSITIVO ELETTRONICO DI MESSA A TERRA (RESISTIVO) ELECTRONIC GROUNDING SYSTEM (RESISTIVE) Il dispositivo EJB.A/KTM, mediante il collegamento della pinza a parti conduttrici dell’autobotte, consente di disperdere verso terra le cariche elettrostatiche generate durante le operazioni di carico e scarico. L’unità elettronica verifica le condizioni di resistenza e, se idonee, abilita la messa a terra e la commutazione del contatto di scambio che pilota la pompa dell’autobotte, segnalata dalla accensione della spia verde. Caratteristiche: Disponibile anche il dispositivo EJB-B/KTM completo di 2 pinze. La prima unità elettronica verifica le condizioni di resistenza della pinza 1, se idonee segnalata dalla accensione della spia verde 1, la seconda unità elettronica verifica le condizioni di resistenza della pinza 2, se idonee segnalata dalla accensione della spia verde 2, in questo caso verrà abilita la messa a terra e la commutazione del contatto di scambio che pilota la pompa dell’autobotte. In caso di condizioni di resistenza non idonee per la pinza 1 non sarà possibile procedere con la verifica delle condizioni di resistenza per la pinza 2 The apparatus EJB-A/KTM, by means of the clamp connected to conductive parts of tank truck, disperses to the ground the electrostatic charges generated during load and unload operations. The electronic unit of the apparatus verify the ground resistance, ad if it’s acceptable, allow round connection and it switches the SPDT contacts which enable/disable the pump of tanker and it is signaled by green light. Features: Also available the EJB-B/KTM device complete with 2 clamps. The first electronic unit verify the ground resistance of the clamp 1, ad if it’s acceptable signaled by the green light 1, the second electronic unit verify the ground resistance of the clamp 1, ad if it’s acceptable signaled by the green light 2, in this case allow round connection and it switches the SPDT contacts which enable/disable the pump of tanker. In case of resistance conditions not suitable for the clamp 1 it will not be possible to proceed with the verification of the resistance conditions for the clamp 2.
