I discover some errors in the code I posted yesterday.
Code:
  btn1:                   'actionare buton up
  
  if but1=1 and rel2=0  then
  
  'this lines added ----------------
    Gosub StartTimer   ' Start the Elapsed Timer
      IF SecondsChanged THEN
        SecondsChanged = 0
        IF Seconds = 10 THEN  
           TimpulUP=1 
        ENDIF
      ENDIF
  '----------------------------------  
           high rel1
           TMR1ON = 1 
           pause 20
                            
'----------------------- // ---------------------------------------
'----------------------- // ---------------------------------------  
  
  btn2:               ' actionare buton down
  
  if but2=1 and rel1=0  then
  
  'this lines added ----------------
    Gosub StartTimer   ' Start the Elapsed Timer
      IF SecondsChanged THEN
        SecondsChanged = 0
        IF Seconds = 10 THEN  
           TimpulUP=1
        ENDIF
      ENDIF
  '----------------------------------  
           high rel2 
           TMR1ON = 1 
           pause 20

  adcin 3, adval
   vt=adval * 5000
   vt=div32 1023
  
  for cnt = 1 to 5
          if vt > 270 or timpulUP=1 then      
              u=u+1
                      if u > 5 or timpulUP = 1 then
  	              gpio.0=0
                      gpio.5=0
				Gosub ResetTime
                      endif
              pause 50
              goto check            
          else
              u=0
  Gosub ResetTime
          endif
  next cnt
  
'----------------------- // ---------------------------------------
'----------------------- // ---------------------------------------

Still not work fine...
