Daily inspection and maintenance of ptc electric heater
Processing after system crash and power failure: When the field equipment crashes or loses power before data collection, it is only necessary to restart the system and run the monitoring system to resume detection, which basically has no impact on the system.
Daily inspection and maintenance of ptc electric heater: check whether the system operation program is in normal operation. The normal running state refers to the running program is not shut down abnormally, the connection between the upper and lower computers of the system is normal, and whether the daily inspection can be realized normally (the realization of normal daily inspection means that normal daily monitoring data can be obtained), etc.
Check whether the power supply of each on-site data collector is normal (normal power supply means: the main power, 220V AC power, and 24V DC power indicators are always on). The electric ball valve checks whether there is abnormal leakage at the connection between the on-site data collector and the transformer. Check that each pressure indication is normal.
The pressure indications are: the total pressure indication of the pressure reducer gas cylinder should be above 5.okg/cm2, if it is lower than this pressure, it should be replaced with new nitrogen in time; after the first stage of decompression, the pressure has been set within the range during debugging , Incompetence Common problems: system crash, processing after power failure: when the field equipment crashes or power failure before data acquisition, just restart the system and run the monitoring system to resume detection, basically no problem to the system. influences.
