4.3 Parameter Setup Table
Parameter Name Range Description Factory value
PR 0 parameter set mode 0 to 3
0
parameter can be read and written
other parameter values cannot be modified until this parameter is set to 0
1
1 all other parameters (PR 1 to PR 29) are read-only
2
Factory Restore – Use Factory Restore to recover the factory default values for ALL
parameters (PR 0 to PR 29). Hereafter the controller has to be reset by pressing “UP”
and “DOWN” at the same time.
3
After setting the parameters from PR 6 to PR 10 to the actual date and time, you
must set PR 0 to value “3”. The controller then stores the actual date and time to the
internal clock and PR 0 is automaticly changed back to value “0”.
PR 1* maximum power point voltage 0 to PR 2 real maximum power point voltage of the whole PV generator 530 V
PR 2* open circuit voltage PR 1+1 to 1,000
real open circuit voltage of the whole PV generator
Interlock function between PR 1 and PR 2: If necessary, the modification of PR 2 has
to be coordinated with the modified value of PR 1
650 V
PR 3* rated voltage 1 to 1,000 rated voltage of the motor load 380 V
PR 4* rated current 0.1 to 300 rated current of the motor load (associated with the rated voltage from PR 3)
according to
pump model
PR 5 start up delay 1 to 150 start up delay time after power up or shut down (in seconds) 30 s
PR 6 year 2,000 to 2,999 year (must be set to actual date)
PR 7 month 1 to 12 month (must be set to actual date)
PR 8 day 1 to 31 month (must be set to actual date)
PR 9 hour 0 to 23 hour (must be set to actual date)
PR 10 minute 0 to 59 minute (must be set to actual date)
PR 11* resources of frequency instruction 0 to 2
0
Manual START and STOP: 1) Press the [RUN] key to start the pump, while the initial
frequency is determined by PR 12. 2) Press the [UP] and [DOWN] keys to modify the
operating frequency. Only for testing purpose
1
1
Fully automatic operation: Pump starts automatically, when sufficient power is
present. The operating frequency is adjusted accoring to the sunlight intensity (MPP
tracking)
2
Manual start of automatic operation: Press the [RUN] key to start the pump, the
operating frequency is adjusted accoring to the sunlight intensity (MPP tracking)
PR 12 reference frequency 0 to PR 13 initial frequency when PR11 is 0 20 Hz
PR 13* maximum operating frequency 0.01 to 60
to protect the motor load, maximum operating frequency must be in line with rated frequency
of the motor
50 Hz
PR 14 stopping frequency 0 to 60 pump stopps, when the output frequency drops below the set value 20 Hz
PR 15
setting for float switch 1
(white cable, red wire, S-8)
0 to 9
0 no float switch (sensor deactivated)
0
6 float switch normally closed
7 float switch normally open
8 float switch normally open (for dual switch mode with float switch 2)
9 float switch normally closed (for dual switch mode with float switch 2)
others Do not set other values, it may cause the inverter to work abnormally
For “Dual switch mode”, both float switches must be set to value “8” or “9”
