Low and high pressure control

Low dan high pressure control
In each machine must have any protective device to avoid fatal damage to the machine, the machine nor Air Conditioner (AC). In some types of air conditioners that have a large PK is certainly equipped tool called pressure control / pressure control refrigrant. Pressure control is a function to start and stop the compressor at normal times and in the event of abnormal pressure. Pressure control consists of:
1 Low presure control (LPC​​) Low pressure control serves to provide protection terhadapa low pressure overload.
2 High pressure control (HPC) High pressure control serves to provide protection against excessively high pressure.
Pressure control is a separate, single pressure control (low or high press press), and some are combined into one unit commonly called Dual pressure control. For the Type Single pressure control is usually found on the type of AC panel, although some are using the Dual low pressure and high pressure control. The workings of this tool: - Low pressure control (LPC​​) contacts can normaly closed (NC) will be open when the pressure drops below the settings, for example in this press Low setting on the pressure of 35 psi when under the pressure of this contact will be open and will automatically break the current into the compressor so that the compressor directly mati.- high pressure control (HPC) contacts can normaly closed (NC) will open in case of excessive high pressure setting on the HPC, HPC example of this in the sett at 300 psi then contact NC will open and break the current in the event of pressure in excess of setingan.Settingan low and high pressure control is in the factory default settings as default (factory setting), but we still can change it if it is in a sense necessary.
