high pressure reached value of this parameter,
the I / O output terminal select 25, then it will
output arrival signal.
when feedback pressure less than the low
pressure reached value of this parameter, the I
/ O output terminal select 26, then it will
output arrival signal.

④Multi-function constant pressure water supply pump specific parameters
E08 regular rotation
interval
According first start first stop principles to
control pump rotation, rotation time of 0.25
hours
Electromagnetic
switching action delay
When set up a station pump (drive motor) to
switch from variable frequency industry
frequency , or from industry frequency to
variable frequency, and set its electromagnetic
switching action delay time is 0.5 seconds.
Pump switch to judge
the time
To set the determine time 100 seconds from
inverter output frequency reaches the upper
limit frequencies until increase pump (drive
motor); or from inverter output frequency
reaches the lower limit frequencies until
decrease pump (drive motor).
Constant pressure water
supply configuration
Shutdown: When the inverter failure,the
rotation switching way is from variable
frequency pump to industry frequency and
the pump maintain the status.
N. 1 ~ 3 pumps are frequency controlled
pump, pump 4 is soft-starter controlled pump.
Multi-pump control mode, displays the status
of each pump
Multi-pump control mode, set the control
mode of each pump, i currently set to Full
Stop
