6-7 Wiring for Motorized Trochoid Pump Motor
CAUTION
- When lubricating with a motorized trochoid pump, always prime before starting the main motor. Abnormal temperature
rise, seizure, and other device damage may occur.
(1)
Vertical frame sizes 6275, 6275DA Use a trochoid pump for independent lubrication. The pump requires a separate power source.
(See Table 6-5, gure 6-4)
(2) For motorized trochoid pump wiring, see gure 6-5. Wire R-U, S-V, T-W. The pump motor rotates in the specied direction. (For
Japanese domestic standard specications. Consult with us for special specication, such as overseas specications and motors not
manufactured by Sumitomo.)
(3) Between the motor for the motorized trochoid pump and main motor, t with interlock that satises the following two functions. (See
gure 6-5)
[1] Start time: If the motorized trochoid pump does not activate, do not activate the main motor.
[2] While running: If for any reason the motorized trochoid pump stops, stop the main motor.
(4) To ensure good lubricating conditions, start (prime) the motorized trochoid pump at least 30 seconds before the main motor.
