Description :

1. Automatic test function: the machine can self perfrom automatic scanning test for an internal return motion or circuit break inside the switchboard, to facilitate the maintenance/repair test motion to turn from complication into simplicity, and upgrade work performance and reliance of the mainframe.
2. Storage function: the return detection shall only go through confirmation of a fixed period of time prior to engagemement of alarm motion, to reduce the disturbance and error report situation of general circuits, and upgrade the reliability of the mainframe.
3. Reserved power protection device: under the condition of power suspension, the reserved power with a power release till below DC-18V, power discharge will be automatically stopped,to extend the battery service life.
4. Quality control: the parts used for the operation panel of the machine and internal base borad are all through CN squality recognition; the mainframe before ex-plant shall go through a strict test to ensure service function to be normal and without an error.
5. Humanistic design: the internal base boards are all in modular design; the external line output/input is separated by a terminal board; and due protection measures are provided to the input terminal. If an insitu wrong connection of external power into a return board, it is only required to replace the return board of the said return, without a need of dismantling external distributing circuits, to facilitate the maintenance / inspection performance to be upgraded considerably.
