*1 The upper limit spm in EXT mode
*2 spm increases/decreases as pushing the UP/DOWN keys. Pressing either key for
more than three seconds, spm changes quickly.
*3 The controller becomes more resistant to chattering as read time is set longer but
then becomes less capable of reading the short pulse signal. "T-5", "T-10" and "T50"
are the approximate time (msec) to read the external pulse signal. An ON time pe-
riod of the pulse signal shall be longer than the read time.
*4 Note that the pump starts to run as returning to the wait state in the manual mode as
long as the pump is receiving the STOP signal and "M-ON" is selected.
