JPM MPS2 Coin inhibit c problem

Recommended Posts

I have a problem with the coin collector of a machine I bought. Inhibit C does not work.
Only the of the four of the different coins are accepted
I have noticed that one cable on the “Coin I/f†connector wat cut off. I think that I could be the problem.
Can anybody help me out?

 

Also on startup, number "3" is show on the smal display followed by an "eci" message on the big display

Yes reconnect those wires, I see 2 that are cut.

Also the machine may inhibit large coin denomination entry if the smaller coin denomination tubes are low.

For example in a UK machine, it may not accept pound coins if the 10p tube was low.

Only one wire is cut off, but I don’t know where I should connect it to?

The machine only takes the smaller coins. The tubes are full, and the level sensors are working correctly.

Does anybody know where I should connect pin11 on the coins connector to?

I see a green/black snipped in the first photo and a black/brown in the third.

From the manual -

Coin Inhibits There are four T.T.L. outputs, output 7 to output 10 connector HD10, to operate electronic coin acceptor inhibits.

There are five open collector outputs, output 6 and output 11 to output 14, connector HD10, to operate electromechanical AC solenoids via a triac.

Coin Inputs

One input, input 20 HD20, is configured for microswitch use.

Inputs 21 to 24 connector HD1 0 are used for electronic coin accept signals.

Inhibit Inputs

Inhibit inputs are used to detemine which coins are accepted by the mechanism. Coins are accepted if the inhibits are pulled low. If the line is pulled up or open circuit then coins will be rejected.

Inhibit Accept Level -0.5v or less,

Inhibit Reject Level -More than 2v or open circuit.

Coin Handling - HD10

The coin handling interface allows tor the following:
A) Four coin inputs (open collector NPN transistors).
B) One coin input (Microswitch).
C) Four non-payout sensors.
D) Four level detectors.
E) Four TTL inhibit outputs.
F) One high current NPN output (series 10 inhibit).
G) Four high current NPN outputs (DC solenoid drives).

Does anybody know where to connect the cut off wire on pin 11 to?
