12.1-12-15
When all the motors are running and water pressure is sufficient, the fixed time circulation is not
enabled. If motor 1 and motor 2 run to reach a balance in water pressure and when the time reaches
the setting for Pr.12-02, motor 1 runs without using mains electricity (run by the motor drive). When
the time reaches the setting for Pr.12-03, motor 3 runs using mains electricity, and the operating time
of each motor resets. Once it reaches the time setting for Pr.12-02 again, motor 2 runs without using
mains electricity. Then when time reaches the setting for Pr.12-03, motor 4 runs using mains
electricity. The time sequence Diagram 12-14 is as shown below

Fixed Quantity Circulation Output Delay
Default: 1.0
Settings 1.0–3600.0 sec.
 Under Fixed Quantity Circulation (Increment) mode, the first motor of the drive switches to the
supply mains through the setting time for Pr.12-03, then switches to the second motor through
the setting delay time for Pr.12-09.
