MTL2213 Power Failure Protection MTL

Description

MTL2213 Power Failure Protection MTL

MTL2213 Power Failure Protection MTL

The MTL2213 enables three 100VA safe-area loads to be controlled independently by three light-duty on/off switches or certified proximity detectors in a hazardous area. Switches and proximity detectors may be mixed. The three input circuits are interconnected but fully floating. For proximity-detector and some switch applications, a phase-reverse link allows alarm conditions to be signalled for either state of the sensors. ‘Alarm’ means relays de-energised with their on/off contacts open, and all three circuits have to operate in the same fashion. This compact low-cost unit is suitable for a wide variety of applications. The MTL2213 supersedes the MTL2212 for which it is a direct replacement, except that only terminal 8 can be used for connecting to earth.

*NAMUR and DIN 19234 standards for proximity detectors

Check the integrity of the application software
(1) Whenever there are any modifications to the system’s logic or configuration data, a software backup must be performed again.
(2) For systems that start automatically when powered on, the application system software is usually automatically started after the operating system starts. If there are no abnormalities or error messages, the startup passes smoothly.
(3) Start the system’s own monitoring, error checking, and self diagnosis software and conduct inspections. All functions should meet the manufacturer’s requirements. The items in the application software list provided by the manufacturer should be complete; You can also scan and check the integrity of the software system based on system startup or using the provided utility tools. The system storage devices also have capacity reserves that meet usage requirements.
(4) Start other application software for each workstation separately, and there should be no error alarms.
