Programs list:
P-11 : triggered, on (non-locked mode)
P-12: triggered, on, triggered again, off (self-locked mode)
(P-13 to P-21 are delay modes)
P-13 : triggered, on, delay TA, off (triggered again in TA is invalid)
P-14 : triggered, on, delay TA, off (triggered again in TA, Recount-down TA )
P-15 : triggered, on, delay TA, off (triggered again in TA, count-down“ displaying time +TA” )
P-16 : triggered, on, delay TA, off (triggered again in TA, Reset, display----)
P-17 : triggered, on, delay TA, off (triggered again in TA is effective)
P-18 : Power on again, on, delay TA, off
P-21 : triggered, delay TA ,on
P-22: Triggered time more than TA, on
P-23: Triggered ,delay TA , not triggered again in TA, on
P-24: Triggered time more than TA, on, not triggered again in TB, off
P-25: Triggered time more than TA, on, Triggered time more than TA again, off
P-26: Triggered ,on , delay TA,off
P-27: if Triggered signal is pluse, off ( pluse cycle less than TA )
P-28: Power on again , delay TA, on , not off until power off.
P31-P33 are cycle modes
P-31: Power on again, Infinite cycle until power off : on, delay TA, off, delay TB
P-32: Triggered , Infinite cycle until power off: on, delay TA, off, delay TB
P-33: Triggered , Infinite cycle until triggered again : on, delay TA, off, delay TB
P-34: Power on again, delay TA, on, delay TB, off
P-35: Triggered, delay TA, on, delay TB , off
P-36: Triggered time more than TA, on, delay TB, off
P-37: Triggered, on, delay TA, off , delay TB (triggered is invalid in TA or TB)
P-38: Triggered, on, delay TA, off, delay TB, on, delay TA, off
