operation.
26: Check of Contactor 3K1:
Used to check
the contactor for Pump #3 variable frequency
operation.
27: Check of Contactor 3K2:
Used to check
the contactor for Pump #3 line frequency operation.
28: Check of Contactor 4K1:
Used to check
the contactor for Pump #4 variable frequency
operation.
29: Check of Contactor 4K2:
Used to check
the contactor for Pump #4 line frequency operation.
30: Check of Contactor 5K1:
Used to check
the contactor for Pump #5 variable frequency
operation.
31: Check of Contactor 5K2:
Used to check
the contactor for Pump #5 line frequency operation.
In the case of a constant-pressure water supply, verify if the contactor is in the indicated
operation status by connection to the NORMALLY ON/OFF contacts of the pump control
contactor. If the detected status of the contactor is different from the indicated status, a
contactor fault of the water supply system will be reported (Er.cno). If there is a contactor
fault, the water system will shut down to prevent the fault from escalation. Please rectify the
fault immediately.
32: Auxiliary Setting Channel Disabled: If this signal is effective, the auxiliary setting function
will be disabled.
33:
Switching of PID settings to AI2:
When this signal is effective, the PID setting channel will
be switched to AI2 analog voltage/current settings in a forced mode. When this signal
becomes ineffective, the PID setting channel will be restored to the channel assigned by
F7-01.

:
Shutdown DC-braking:
In the shutdown process, when the working frequency is lower
than F1-17-“Shutdown/DC Braking Frequency” (and F1-16=2), if this signal is effective,
the shutdown DC-breaking will be effective. The DC braking will not end until the braking
time exceeds F1-19 and the command is repealed.
35: Process Identification Disabled:
When this signal is effective, PID will be disabled. PID
will not be enabled until this signal is ineffective and there is no other priority operation
mode.
36: PID Parameter 2 Options: When F7-11 “PID parameter transition mode”=0 and is
effective, choose PID Parameter 2 (
F7-08
~
F7-10
); when the parameter is ineffective,
choose PID Parameter 1 (
F7-05
~
F7-07
).

39: Three-wire mode shutdown command, Internal Virtual FWD Terminal and
Internal Virtual REC Terminal: Refer to the description of the F4-13 terminal
operation mode on Page 55.
40: Maintenance of Analog Quantity Frequency Settings:
If this signal is effective when the
frequency settings is acquired by analog input, the frequency settings will not vary with the
analog input. If this signal is ineffective, the frequency settings will vary with the analog
