*) After modification of parameters marked with *, the
next operation cannot be performed until the controller has
been reset.
PROMPT: Record is not made because of the
under-voltage fault of input voltage when the sun
irradiation is too low.

startup delay time after abnormal
water level of well probe 1 or 2

After the water level has been abnormal or idle load protection has been running, the controller
will restart after this period of time (in seconds). While countdown is still higher than 999
seconds, the displayed digits flicker, delay time displayed remains at 999.

When idle load protection parameter is set to 1 and if the actual output frequency
is higher than the frequency set at PR 14, controller activate idle load protection.
