Air conditioning unit water side of the water flow switch how to connect, then which terminal, as well as the switch installed in the water side or the water side to play a role,
There are two screws on the terminal side, there are two sides, I do not know which is the next
The installation position in the unit side of the water, the principle is when the cooling water system failure, if the water stops, it will lead to unit temperature rise, affecting the normal operation of the unit, serious may lead to burn the unit. Normally, a water flow switch will be installed in the pipeline of the cooling water system to monitor the flow of cooling water in real time.
Terminals need that meter test, four terminals are two normally open is normally closed, generally connected to the normally closed.
Once the cooling water stops flowing, the water flow switch will send an alarm signal to the microcomputer control panel, Issued an alarm sound, to avoid the occurrence of the accident.
