The FUJ TP-G1W-DY is a DY Special Keypad ECO, purpose-built for pump applications. This is the operator interface for a FUJ pump drive — not a general-purpose HMI, but a dedicated keypad that carries the pump-specific overlay and firmware personality. If you are supporting an installed FUJ pump drive and need the exact replacement keypad, this is the order code that matches the original equipment.
Why this keypad matters for pump installations
A pump drive keypad is the primary interface for setting speed, monitoring flow, and reading fault codes. The TP-G1W-DY carries the ECO pump firmware, which typically includes pre-loaded pump curves, anti-cavitation logic, and energy-optimization routines. Having the correct keypad on hand means the commissioning engineer can download parameters and the site electrical engineer can read out running hours without needing a laptop or software dongle. For a line-down scenario, swapping this keypad restores full local control immediately.
