* Four LEDs (Tb0, Tb1, Tb2, Tb3) are used to indicate the off-timer period. Depending on the base timer step
option, timer step may be 0.5 hour or 1 hour as indicated in the diagram.
If SC2128A is selected with 4 hour timer
option
Tb0=0.5 hour
b1=1 hour
b2=2 hour
b3=4 hour
If SC2128A is selected with 8 hour timer
option
Tb0=1 hour
b1=2 hour
b2=4 hour
b3=8 hour
The time schedule is the sum of all ON LEDs. For example, if SC2128A is programmed with 0.5/1/2/4 hour
accumulated timer option, and is Tb0 is ON, Tb1 is OFF, Tb2 is OFF, Tb3 is ON, then the schedule period is 4.5
hours (0.5 hr + 4 hr).
* Rhythm LED and Sleep LED indicate SC2128A operation modes.

* Three LEDs – Low, Middle and Strong – are used to indicate the respective output status of LO, MI, ST output.
LED being ON indicates output active (L). LED being OFF indicates output inactive (Z). Only one output among
LO, MI and HI may be active at a specific time.
* Swing1 LED, Swing2 LED and Light LED indicated respective output status of SO1, SO2, and LIT.
