(c) Saving of Operation Data
Mainly for investigating causes of market claims, operation data are always saved in memory. If any trouble occurs, the
data writing is stopped and only the operation data prior to the time when the trouble occurs are recorded. These data can
be loaded to a PC via RS232C connector of PCB and utilized for identifying causes.
(i) Operation data for a period of 30minutes prior to the present operation are saved and updated continuously.
(ii) If an anomalous stop occurs, the data are not updated any more.
(ii) Data are written in based on 1 minute sampling interval and next data will be transmitted to PC upon demand.
