Honeywell 10310/2/1 Earth Leakage

System requirements: Safe grounding: When the factory has Zener grounding or belongs to a lightning strike area, the grounding resistance should be 0.1 Ω, and when the above conditions do not exist, the grounding resistance should be less than 5 Ω; Lightning strike to ground less than 0.1 Ω; The grounding resistance of MRG grounding is between 1 Ω and 5 Ω depending on the situation, and the distance between MRG grounding and other grounding is not less than 3m. After actual measurement, the safety grounding resistance of our TPS in our factory is 0.75 Ω, which meets the system requirements according to the situation in our factory; The grounding resistance of MRG is 0.91 Ω, which is also within the system requirements. But 4 meters away from the MRG ground is our factory’s 305 distribution room. In order to eliminate interference from the 305 distribution room, we have remade the MRG ground, which is far from the 305 distribution room. The new MRG ground resistance is 1.17 Ω. After using the new site, NIM has been running well and has been running for 6 months since April this year, without any previous failures. 3.2 Precautions when developing applications using CL within TPS. Control Language is a built-in control engineering language in TPS that can be used to develop continuous, sequential control, calculation, and other applications. It can access all parameters and functions of HPM/APM, and its installation, startup, and monitoring are executed by PM points. CL is indeed a great control language, especially when developing complex sequential control programs. It is much more concise and convenient than modular Logic Point.
