Cycle modes of inverter pump:
Pump drived by the inverter is not fixed to 1 set and maximum to 4 sets.
Figure 4.4.117 Cycle modes of inverter pump
In addition to the two basic operation modes provided from 1 to 8 pump card, it can only use the Relay in
the control board to enable the cycle modes of inverter pump.
* Cycle modes of inverter pump in the control board: Run via a Relay with a pump to start the cycle
modes of inverter pump.
Figure 4.4.118 Cycle modes of inverter pump in the control board
24-00=0: Function of 1 to 8 pump card and 1 to 3 Relay are disabled.
24-00 = 1: in the fixed modes of inverter pump, first on and last off; then stop all.
Pump (motor) drived by the inverter is fixed. Switching off the pump (motor) is by the sequence of the last
on and this mode is applicable to different pump (motor) ratings.
24-00=2: only inverter pump stops in the fixed modes of inverter pump.
When the inverter sends the stop command, only the pump (motor) stops but the Relay keeps on.
24-00=3: in the fixed modes of inverter pump, first on and first off; then stop all.
Switching off the pump (motor) is by the sequence of the first on (longer operation time) to make the
pump (motor) be used for the eq ual frequency and this mode is applicable to the same pump (motor)
ratings.
