Terminal sign Function
POWER R, S, T 3PH AC input terminal, connected to the grid
MOTOR U1, V1, W1 3PH AC output terminal, connected to the air compressor main motor
FAN U2, V2, W2 3PH AC output terminal, connected to the fan
SOLENOID
220V/TAH,
110V/TAL,
0V/TC
220V/110V output terminal, connected to solenoid valve coil
Note:
1. Max. output power of internal power-frequency transformer: 15W
2. When you choose the solenoid valve with 220V coil, connect the
solenoid coil to 220V and 0V connecting terminals;
3. When you choose the solenoid valve with 110V coil, connect the
solenoid coil to 110V and 0V connecting terminals.
Each machine must be grounded. The grounding is implemented
through the two PE terminals on the machine, and the grounding
resistance is less than
10Ω.
Note: Do not connect the connecting terminal of solenoid valve to other external loads; if the power of
solenoid valve coil exceeds 15W, the power-frequency transformer inside the integrated machine will
need to be customized or connected to external 220V/110V power independently.
