Select Mode:
After power on,long press K12 seconds later into the select function mode,P1-1~P1-4forchoose.
P1-1 operating modes:
A signal to trigger relay, time is up,the relay
disconnect users,You can set relay time T,click K2 the hundreddigital
tube starts flashing,then press K3, the hundred digital change;click K2
ten digital tube starts flashing,then press K3,ten digit changes;click K2 bit digital tube starts flashing, then press K3, single-digit change;then click K2,; digital pipe does not blink,then press the K3, shifting the decimalpoint,the decimalpointin abitindicates 0-999minutesin ten represents 0 to 99.9 seconds withou tadecimalpointrepresents 0-999 seconds;goodchoice,bringing the time setting is completed.Short press K1,enterfunction offine-tuning settings,triggerthedefaultdelayperiod is invalid, press K1, during the delay trigger active(re-timing),clickon the K1, during the delay reset (timer turned off,the relay reset) press again to repeat the default settings for the first time.
P1-2 operating modes:
Asignal trigger ,digital countdown begins,X seconds after,there lay open Y seconds,then close.Users can set the relay time X,Y;P1-1different time settings similar to the blue lights that set the relay time,blue light indicates setting relay off time. Short press K1,
enter function offine-tuning the set,the default trigger is invalid during
the delay,pressK1,during the delay trigger active(re-timing),then click
the first repeat default settings.
P1-3 operating modes:
Open X seconds,disconnect Yseconds, infinite
loop.Users can set the relay timeX,Y;time setting similar to P1-2.Short
press K1,enter function offine-tuning set,The default function is:set up
an electric circuit the relay first open, press the K1,there lay first close.Press again to repeat the default functionality.
P1-4 operating modes:
A signal to trigger the relay open but do not start the timer,when the trigger signal disappears,digital count down begins,X time after,the relayclose; During the delay,again to the signal,digital count down canceled, stays energized, the signal disappears, restart count down; (equivalentto release the button to start timing, commonly usedin power-offdelay).Users canset the relay time X; time setting similar to P1-1.
