paano ang operation ng circuit, pag press ng start switch forward ang takbo ng motor then pag na-hit ang limit sw reverse naman?
magho-hold ba yung limit sw sa close position or mag-o-open agad after mag reverse yung motor?
pag nag-open agad yung limit sw magpo-forward agad yung motor ng hindi pa nakakatakbo ng matagal sa reverse.
assuming naman na magho-hold yung limit switch sa close position at nag-reverse, paano pag press ng stop switch hindi naman hihinto
at paano naman ito babalik sa forward?

@nanotech
sa drawing wala nmn holding contact sa reverse limit switch.. so mag open agad yun.. unless lagyan un mechanically.
ung revision na additional contact sa reverse. mag swicth off ang motor even actuated un reverse LS. other than that ganun din.
wala nmn clear na control narration un TS kaya pwede yan, sabi nya lang mag reverse pag nareach un LS.

dun sa 1st drawing kung wala ang aux contact sa MR, let say, nag-jam yung LS kahit pindutin ang stop switch naka-on pa rin ang MR.
kaya mas mabuti na merong aux contact sa MF & MR ay para masigurong mag-o-off ang motor.
sa pagdesign ng kahit na pinaka-simpleng motor controller, para sakin, it's a good practice na i-consider ang safety.

oo nga mas maganda un..dis able lahat ng rung.. kun sakali kulangin ng NO contact.. un ang unang ilagay na contact sa left rail, then ung forward and reverse na rungs both dun kukuha ng signal.. in that way isa lang kailanagn na NO instead na 2.

sana ito tama na sa gusto mo mangyari  pede naman d lagyan ng timer basta make sure na maliit lang ang torque ng motor mo para kung forward state cia taz bigla cia mag reverse d masira motor mo. kung may load naman cia ok na yun. Yung washing machine meron din delay pag magreverse cia ng ikot eh... sa skul mo ba gagamitin to ^^ post lang po any correction ah.. thnx.. cencia kung lagi me nakalink d ko alam kung pano mag post ng picx d2 eh hehehe... |

Subukan mo rin to pre...
StopPB Strt PB R3
--I/I---+--I I--+---------I/I----------( R1) ' press startPB activates Relay1
| R1 |
+--I I--+
|
| LSReverse R1
+----I I--+-------I I---------(R2)-- ' actuates LSReverse energizes Relay2
| R2 |
+- --I I--+
|
| LSForward. R2
+---I I---- +---I I----------(R3)-- 'actuating LSforward energizes R3 and de energize R1&R2
| R3 |
+- --I I-- -+
|
|
| R1 R2
+----I I----I/I----------------(FOR) ' IF R1 IS ON AND R2 IS NOT THEN FORWARD
|
| R2 R1
+----I I----I/I----------------(REV) ' IF R2 IS ON AND R1 IS NOT THEN REVERSE

eto yung aking modified version base dun sa huling ginawa ni boss shadow: (depende sa connection sa terminal 1 or 2 connect to 1 for start-forward or 2 for start-reverse) note: additional component may be required to be fully safe & functional, for educational purposes only.  |
