sequential timer quick reference guide x state of the art microcontroller design x user friendly programming for on/off time selection up to 99 hrs 59 mins. x 7 segment display indication for channel & timing operation. x multiple units can be cascaded to obtain more channels. x program & process value retention incase of power failure. x external contacts for timing initiation & timing pause. x * olp=on line programming hold: when the slide switch on the front panel is kept in the hold position, the timing data is retained in case of power failure. upon resumption of power the timing continues from the point where it has stopped. restart: when the slide switch is kept in the restart position, the timer resets in case of power failure and starts from beginning upon power resumption. external start: by shorting terminals s1 and s2 for minimum period of 120 milliseconds (potential free shorting) or by keeping s1 and s2 permanently shorted, the timer sequence is initiated. single cycle operation: by keeping the terminals c1 and c2 shorted (potential free) on the front panel, the sequential switching of output is executed for one cycle and stops. cyclic operation : by keeping the terminals c1 and c2 on the front panel open, the sequential switching of outputs keeps repeating after the end of each cycle. inhibit: by shorting terminals i1 and i2 (potential free) on the front panel, status of relays/triac output (on or off) is maintained irrespective of the program timing. by removing the short, the programmed timing continues and relay / triac respond as per the preprogrammed timings. model function output source voltage time range ST-10 sequential switching with olp relay output relay 110v ac 240v ac 0.1 sec to 99 hrs 59 mins ST-10m1 sequential switching without olp relay output relay 110v ac 240v ac 0.1 sec to 99 hrs 59 mins st-6m1 6-channel sequential switching without olp relay output relay 110v ac 240v ac 0.1 sec to 99 hrs 59 mins ST-10m2 sequential switching without olp triac output triac 110v ac 240v ac 0.01 sec to 99 hrs 59 mins s a l i e n t f e a t u r e s o r d e r i n g i n f o r m a t i o n s p e c i a l f e a t u r e s www.datasheet.co.kr datasheet pdf - http://www..net/
