detection function of water level of intake sump for water supply applications. The inverter
receives the signals of water level of intake sump in real time. If the water level changes from
high to low, PID1 reference will be normal set value when the water level above lower limit;
PID1 reference will be P22.43 when the water level below lower limit and above water
shortage level; all water pumps of the control system will stop when the water level below
water shortage level. If the water level changes from low to high, the system will stop when
the water level below lower limit; PID1 reference will be P22.43 when the water level below
upper limit and above lower limit; PID1 reference will be normal set value when the water
level above upper limit.
5. Abnormal PID1 feedback pre-alarm function
: Goodrive300-16 has built-in abnormal
PID1 feedback detection pre-alarm function. The inverter receives feedback signals in real
time. If PID1 feedback is P22.45 and no more than P22.44, the inverter will display
“-LP-”
indicating PID1 feedback is too low. If PID1 feedback is P22.47 and no less than P22.46, the
inverter will display
“-HP-” indicating PID1 feedback is too high. Press PRG/ESC key to
return to stop or run displaying interface and other keys are invalid. If PID1 feedback is
normal, return to stop or run displaying interface automatically.
6. Multi-motor manual start test function
: The manual start test function consists of
manual soft start and manual circulation.
The manual soft start is only valid for circulation variable frequency motors and needs fitting
with the terminal corresponding to the function of the motors. When the manual soft start and
the signal of manual soft start of variable frequency motors are valid, the inverter will control
the motor to start and run to P22.38, then coast to stop and connect the motor to power
frequency power. If the corresponding S terminal of the motor is invalid, stop immediately. If
the corresponding terminal of manual soft commissioning command is invalid, all motors will
stop immediately.
When the manual circulation signal is valid, the circulation process for power frequency
motors: connect the motor to power frequency power supply and disconnect the power
supply after running a certain time, repeat with the second valid motor and so on. When the
manual circulation signal is valid, the circulation process for variable frequency motors: start
operating the motor in switch frequency P22.22, control the inverter to coast to stop after
running a certain time, then connect the motor to power frequency power supply and
disconnect the power supply after running a certain time, repeat with the second valid motor
and so on. All motors under power frequency and variable frequency will stop only when the
manual circulation signal is invalid.
