It is Relay in the 1 to 8 pump card used for function of inverter pump.
24-07 = 1: Built-in 1 to 3 Control Mode
It is Relay in the control board used for function of inverter pump.
Only R1A~R3A in the control board can be used and Relay in 1 to 8 pump card cannot be used.
It is required for the following conditions to enable this control mode.

24-00 is only set to 1~3 and 6.

24-01 is only set to 0xxx (Relay 4 is disabled).

24-02 is only set to 0000 (Relay 5~8 are disabled).
Note: If user does not follow the above requirements (24-00, 24-01, 24-02, and 24-07), errors will coour
when user give commands to the inverter.
Refer to the following table for controlling the maximum value of pump under the different setting values of
24-00 and 24-07.

 If 24-07=1, R1A is fixed to support Relay 1 controlled by pump and function of parameter 03-11
is disabled.
 If 24-07=1 and 24-01= xx1x, R2A supports Relay 2 controlled by pump and function of
parameter 03-12 is disabled.
 If 24-07 = 1
，
24-01 = x1xx, R3A supports Relay 3 controlled by pump and function of
parameter 03-39 is disabled.

Relay switching time is required to be with modes 7 or 8 of parameter 24-00. When the power is on, the
first run motor is the motor 1. If the switching time reaches and all motor are at sleep mode, the motor 2 will
start up and the inverter drives the motor 2. Refer to the following figure for motors change when the Relay
switching time reaches.

Note: It will recount time when parameter 24-00 is enabled or parameter 24-08 changes the Relay
switching time or the power reconnects.
