What are the control conditions for fan linkage control of SF6 leak monitoring system?

1) Automatic start if the indoor state is abnormal: if the sub-regional control function is not defined, the system will automatically start the fan if the SF6 concentration or oxygen level alarm of any indoor detection unit is generated. The duration of continuous ventilation is the set time for continued ventilation until SF6 and oxygen are restored to normal.

2) 24 period timing control start: The interface or upper computer software will prompt the latest fan start and stop time.

(1) A total of 24 time segments are controlled from 00-23, the longest ventilation time that can be defined is 23 hours and 59 minutes (then the period is defined, and other periods are invalid), and the shortest ventilation time that can be defined is 1 minute.

If multiple periods are defined, the timing function needs to be cancelled. If period 00 can be cleared to zero, the timing of the subsequent 23 periods becomes invalid. Similarly, zeroing out any of these periods invalidates all subsequent period definitions. Users do not have to clear zeros individually.

3) Manual forced start: Because it belongs to the forced ventilation key, it is the only key on the keyboard that cannot open the menu item. Define the zone control function: The probe unit numbers defined in the same zone must be continuous.

4) No matter what the above conditions trigger the fan operation, the current fan operation status is displayed on the host interface or the upper computer interface.
