150 electrics

[josharb87]

hello mr timberwolf

 

got a 150 6 inch, close to 300hours on clock

 

problem is that occasionally the rollers when on infeed wont play ball-if the saftey bar has beed activated/reverse feed opperated then press the infeed switch they turn an inch but wont stay on, repeatadly press the switch and they will suddenly work as normal

 

pulled the metal switch cover off today, pulled the wires out and after a bit of trial and error if i disconnect the orange wire on the infeed switch, start the machine, tap the orange wire onto where it should be, then remove it the rollers constantly turn (sorry mr H&S) so im guessing the orange wire is at fault, what is this wire/what does it do and what could be wrong with it?

 

thanks

Hi Josharb87

 

The orange wire on the infeed switch goes back to the elctronic control box and is the reset revert to reset mode from the safety switch, by removing the wire you take away the safety switch, also attached to the orange wire is a black with green tracer wire, this goes to the fwd solenoid latch relay, by removing the orange wire you are feeding false info to the box and by touching it onto the terminal it sees the signal but by removing it again has no chance to act in the safety mode it is looking for when the circuit is made.

 

I suspect that the relay is not working properly by latching in to complete the circuit, this would explain the intermittent operation that you have experienced.

I would advise that you reconnect the orange wire, change the SRB500 relay (this can be purchased for a few pounds at a local automotive shop) and try the system, also in the circuit is the safety switch on the funnel, if the above does not work then check out the safety switch.

 

Hope that this cures the problem

Hi again Josharb49

 

Have been pondering your problem some more and have thrown open the discussion at TW.

 

One further cause of the problem could be a sticking contact on the forward switch, it is worth checking out, as this will also give you the problems you describe.

 

Once again hope the problem gets a cure. Please let me know the outcome.

 

regards

hi mate, after using the method i stated above out of nesisaty for a while, took the time to have a fiddle today, the black wire with green tracer has a little in-line resister(?) near the infeed switch which had a snapped connection, so have temporally wired it together without the resistor thingy, what actually is it/part number/name/function?

 

swapped the 5-pronged relay but no joy, replaced the switch, and it now works, although the old switch appeared to be functioning fine! but the orange wire isnt connected but all functions work! ????? looking at an old chippit, they dont have the3rd orange wire, what exactly is this and what is it supposed to do?

 

thanks

Hi Josharb87

 

The resistor thingy is a diode, the function of a diode is to allow the flow of electricity in one direction only, eliminatig any back feeds that may be around. These back feeds will have an effect on the ''fail to safe'' set up that is present on all chippers. I would recommend that you reconnect this in line, but be careful as if you reconnect in the wrong way round, it will cut your circuit.

 

The orange wire, in the switch is used if you have a high funnel fitted to the chipper, it is for an extra safety stop which you do not have, reconnect back to the terminal with the black with green trace wire for good housekeeping.

 

Glad that you have sorted your problem and that we were able to assist.

nice one, learnt a bit about electrics too!

 

thanks timberwolf guy!
