    Default Allan Timer Malfunction


    mga boss, karon lang buntag, nagpalit ko sa cebu advance electronics ug allan timer.

    akong gitaod.

    for 6 hours, wala jud nagkaproblema ang timer. mo beep jud siya unya sakto ang oras jud..


    karon, gi ablihan nako ang box kay nanguha kog sinsilyo.

    pag ON nako balik sa unit. (PC and timer) ga sige siya ug BEEEEPPP as in long beep jud siya..

    unya, ang iyang LED screen kay 8888 man guro to, wala jud siya mo zero.

    hangtod nga nawagtang ang iyang saba, unya taod taod, namatay na ang timer. ang coinslot nalang ang nagsiga.

    unsa kahay naka ingon ani?

    naa ba koy nasayup sa akong installation?



    BTW, ang akong gigamit nga transformer is 220V to 12V - 2Amp

    kung naa pani warranty, pailisi lang ni bro.. kung dili sila modawat.. aw ilisi nang capacitor og kana sunog nga resistor tupad sa bloated caps. hopefully wala nadaut uban components pero mas maayo kung mapailisan ni nimo gyapon with the warranty.

    Sure ko bro nga imo nang na tap sa isig ka kilid nga wala nimo gigamit ang "0" ang output voltage ana imong gi tapping is 31 VDC unregulated, that`s the reason why nibuto ang imong 1000uf/25V nga filter capacitor, dapat sa 0 ug 12V ra ka ni-tap para maka out siya ug 15-16 VDC unregulated, ang transformer nga imong gigamit is a half bridge full wave type meaning naay center tap so nahug na ug 12-0-12, so kung sa duha ka 12 ka mukuha ug linya nahug na ug 24VAC kay naka series man na ang duha ka coil form 12 to zero nya zero to 12, ni happy new year na nu-on kag sayo bro hehehe

    maayo pa na bro, replace the 7805 IC and the 1000uf/25V capacitor then tap your supply to "0" and "12" that`s 1 amp 12V, kung gusto gyud ka ug full 2A nga 12V you need to take out all the 4 rectifier diode in the timer board kay full bridge / full wave na nga design, install the 2 diodes in both 12V post nya itabo ang duha ka positive side sa diode nya i-tap sa + positive side sa capacitor nya ang ground is ang Zero...now that`s a half bridge / full wave 12V 2 amp. supply
