6. Check Accumulated Operating Times & Action Number
a: Hold and MANUAL to display the operating time (h) and the action number (p) circularly.
To calculate the actual operating time and action number, multiply the displayed values by 10 (max. 99990h & 99990t).
For example: “h0013” and “p0021” refer to accumulated operating time of 130 hours and an action number of 210 times.
b: Release M+ and MANUAL to return to the clock interface.
7. Copy Data Function
Ideal for use where a large amount of ON/OFF and/or pulsation groups have been programmed. By using the dedicated Timer Data Card, it is possible to quickly
copy data from the timer, to another similar timer.
a: Set up and program your SDTC-20-1C timer, including real time, clock display mode etc.
b: Insert the dedicated data card into the timer port of the timer that has been set up
c: Press the READ/WRITE button on the data card until “OUT” is displayed on the timer’s screen. Then press OK on the data card to start data export. After export
has been successful, “O” will be displayed.
d: Insert the data card into the timer you want to copy data to.
