MOUNTING AND WIRING
Mount CT03 into a 45x45mm panel cut-out (Fig.1) and tighten it into place by the snap-on mounting bracket. Wire the timer using
OCTAL connector and strictly following the wire diagram on Fig.2. Do not turn the power supply on while mounting and wiring!

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
st
period, beginning after START) and t2 (2
nd
period or Total time) form 4 different timing modes (see time diagrams
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
