OPERATING
CT03 has two contact control inputs for external (re)start (START) and time-counting hold-up (HOLD). Combinations of two adjustable
time periods – t1(1
period, beginning after START) and t2 (2
st
below). The duration of each period is adjustable within one of the following five sub-ranges: 0.00...9.99 sec, 0.0...99.9 sec, 0...999 sec,
0...999 min, and 0...999 min x 10. There are two control outputs - K1, which activates alternatively with t1 and t2, and K2, which
activates for the total cycle time - whose action can be programmed with parameters
