Help Needed - AMI Contintal 2
Hi all
Posted on this before but thought best start a new thread. I have issues on my Cont 2 with the pin pusher not having enough grunt to push the pins in, used to be ok but has got worse, so far I have 1) Replaced the recitfier (and added 2 fuses as suggested to protect the transformer) - Now get 26-28v out of the PSU 2) Cleaned and oiled the carousel drive moter, that turns ok but the motor is still easily stopped by hand, is that normal? 3) Have replaced the 100mfd cap in the control box 4) Have a second pin wheel installed which is clean and shiny!! But still the pin pusher is very weak, having taken it all out, when it pulses, I get no more than 10v to the coil, the coil looks ok, not burnt or anything, its showing about 18 Ohms when checked Any ideas all? Really stuck now....Like my pins Cheers shaun |

Really stuck now....Like my pins Cheers shaun Could disconnect the power supply output plug, and take the 24vdc straight to the coil via a cable from the power supply and see if it gives a strong push when powered directly like that, (only do it for a second, do NOT leave power on the coil for long periods or it could burn out) If so, then you have a bad connection between the pusher and the supply, check all relay contacts, plug pins and sockets in the path to the coil are ok. The carousel motor should not be able to be easily stopped by hand, wire it direct (as shown above) and see if it improves. make sure you run it in the right direction though. Same comments, measure across the motor when it is running and if the motor voltage is low under load check for bad connections, as stated above. It could be normal for the voltage to drop a couple of volts or so, but if you are dropping much below the low 20s under load then there is a big problem there. If there is not a big drop under load then the motor has a problem, might need new brushes etc. Try wiring direct to the motor from the power supply, (make sure it runs in the right direction - if not then reverse the wires to it) If there is still a big voltage drop, then you have a problem with your power supply, or an internal problem with the motor that is making it draw too much current (such as shorted turns etc - though have never seen this in one of these motors). If the motor is ok, then check the power supply for problems, This could possibly be bad fuses (have seen new ones that had a resistance across them and caused problems though this is very rare) bad connections, bad soldering or even bad fuseholder. The output plug might be bad also (socket not grabbing pin firmly enough). |
