In order to avoid ignition sources that could lead to detonations in the event of an explosive atmosphere, defined safety-relevant parameters must be consistently monitored when operating industrial trucks in accordance with the ATEX regulation. Linde MH has developed the EX monitoring app for the continuous monitoring of these values: it ensures maximum vehicle availability by displaying safety-relevant values and errors and providing specific recommendations for action. The app supports forklift truck drivers and fleet managers in operating the vehicle as safely as possible and without failures. It also simplifies maintenance, diagnostics and repairs. "This makes the operation of explosion-protected trucks in sensitive areas even more productive," summarizes Elke Karnarski, Product Manager responsible for explosion-protected Linde industrial trucks and solutions.

Many areas of the chemical, pharmaceutical, cosmetics, food and beverage industries as well as logistics are at risk of explosion because flammable hazardous substances are manufactured, processed, transported and stored. Any ignition sources that could cause an explosion with devastating consequences must be ruled out at all costs. Industrial trucks can be found in ATEX zones 1/21 and 2/22 - these include, for example, production areas where hazardous substances are openly mixed or transferred, as well as areas where hazardous substances are stored and transported in closed containers and could be released in the event of an accident. If gases or dusts combine with the oxygen in the ambient air, an explosive atmosphere can arise. Ignition sources on vehicles are prevented on the one hand by appropriate explosion-proof equipment and on the other hand by the consistent monitoring of safety-relevant parameters - up to 50 values in an explosion-proof vehicle, especially temperature-relevant parameters, resistances, voltages and wear. These include the temperature of the housings of electronic control units and power modules, the brake shoes, magnetic brakes and the drive motor. Until now, it has been standard practice to inform the driver of safety-critical faults by means of a flashing code on the vehicle display. In everyday operation, however, faults are not always identified and dealt with as they should be. With varying consequences - sometimes the vehicle remains out of service for longer than necessary. Sometimes the fault is not checked thoroughly enough. And sometimes the visit of a service technician is inefficient because it has been inadequately planned.

EX monitoring app for preventive maintenance
The Linde EX monitoring app provides drivers and fleet managers in ATEX zones 1/21 or 2/22 with comprehensive condition monitoring. The app checks the explosion-protected vehicle on the spot and shows what specifically needs to be done. It provides information on the meaning of the flashing code and identifies the fault. The integrated two-stage traffic light system indicates the next steps: With the yellow indicator, the vehicle must be cooled down and a maintenance appointment arranged. A red light means: stop and request a service technician. The detailed diagnostics with all values of the monitored components and parameters provide assistance. The app also displays the error history and provides specific recommendations for action. All information regarding the wear of safety-critical components and the remaining operating hours is recorded. The EX monitoring app from Linde MH is a unique selling point. Already available for five series today, it will be part of all future explosion-protected Linde models.
