1) Identifies from when power is supplied or 2 minutes after RESET, and only when set is stopped.
2) An OPEN/SHORT error will occur if the input voltage standard exceeds 0.5V ~ 4.95V range

Replace high/low-pressure sensor
Please re-inspect after connecting
the connector to the PCB
No
Yes
Did the high/low pressure
connector get disconnected from
the PCB?
Refill refrigerant after vacuum
No
Yes
Is there refrigerant inside
the set? (Please check by connecting the
manifold gauge to the service valve)
Refill refrigerant after vacuum
No
Yes
On the high/
low-pressure sensor terminals of the PCB,
is the value of voltage 5V, between pins
3 and 4?
The ▼ mark is the 1st pin on the PCB.
