Powtran PI9000 series User Manual page 145

When the inverter radiator temperature reaches the temperature, the inverter
multifunction DO will output "Module Temperature Arrival" ON signal.
F7.41
Cooling fan control
Used to select the cooling fan mode, if you select 0, the fan will run when the inverter is
running, but in the stop state of inverter, if the radiator temperature is above 40 degrees, the
fan will run, otherwise the fan will not run.
If you select 1, when the fan will always running after power-on.
Note:PI9100A fan without control.

F7.44
Timing run time
The group of parameters are used to complete the inverter timing run function.
If F7.42 timing function is active, the inverter starts as the timer starts, when the set
timing run time is reached, the inverter automatically shut down, at the same time the multi-
function DO will output ON signal.
Every time the inverter starts, the timer will time from 0, the remaining time can be
viewed by d0.20. The timing run time is set by F7.43, F7.44 in minute.
F7.45
Current running arrival time.
When current running time reaches this time, the inverter multi-function digital DO will
output"Current Running Time Arrival "ON signal.
