Machines (2) keep interlocking

[Never_to_old]

2 Machines ,both run fine for a while and then all off a sudden they will interlock,

Have checked and rest all cams , adjusted the SB at different times but they still keep bugging me
they may run without a problem for 10 to 20 games then interlock

Need the normal old info, what motor, switch, is it coasting? check the c2 pins, capacitors, plug wires. If it's an Omega-tek with a solid state sw. it will int. interlock. I use the mechanical switch 6x550 from Grainger.( they have a replacement now for it)

[Never_to_old]

Westinghouse motors, no coasting, All C2 pins and sockets have been replaced across the whole house, the problem still occurs with other chassis,s

Solid state sw or mechanical? Look inside the motor, at first gaurd when the motor stops does the rotor turn like an extra turn or does it stop right away ? If it does'nt stop in 1/2 turn you'll get the interm. interlock. Do you use the spring washer on top of the bearing? You can pull the bearing and the spacer up a touch to create some pressure. Also swap the capacitors with a good pair.

INTERLOCK

In order to energize the table or sweep motor relay, the 24 volt controlling voltage must pass
through the table sweep interlock circuit consisting of TB (table cam switch) and SC (sweep cam switch)
contacts wired in parallel. One of these switches, either TB or SC, must be on to run the
table and sweep motors. If the table and sweep are on a collision course, both TB and SC
will turn off. This removes the controlling voltage from both relays, stopping the table and sweep motors.
Table and Sweep run switches are inoperative in an interlock condition.

Re: Cams/Fingers for Dummies

A Brief Treatise on Cam Switches:


The table and sweep cam switches allow the chassis to monitor the locations of the table and sweep for proper cycling of the pinspotter.


Table cam switches are located on the left next to the table motor, sweep switches are located on the right next to the sweep motor.

The table cam switches from left to right are:



TA1: Determines the home position of the table.



TA1 out of adjustment too far in:

1. Table stops before zero position.

TA1 out of adjustment too far out:

1. Table runs continuously.




TA2: Initiats the sweep run-thru.



TA2 out of adjustment too far in:

1. 1st ball-sweep down to guard position, table continues to run.

TA2 out of adjustment too far out:

1. 1st ball-sweep down to guard position, time delay, sweep runs, clears pins and stops at guard. Table does not come down.




TB: Lets chassis know that table is within range of being hit by sweep

TB out of adjustment:

1. First ball, sweep starts towards pit, table starts up with pins in gripper, both stop, neither will run with SA1 or TA1.





Sweep switches from left to right are:



SAetermines the 2nd guard and home position of the sweep.

SA out of adjustment:

1. Sweep runs up, down and starts to clear deck a second time as the table spots pins. Table and sweep stop because of interlock.

SA out of adjustment too far out:

1. Continuous sweep run.



SBetermines the 1st guard position of the sweep.

SB out of adjustment too far in:

1. After cycle starts, sweep runs continuously.

2. 1st ball - after time delay the table comes down, sweep starts and stops under the table as it comes down to respot pins, table stops.



SC: Lets the chassis know the sweep is in range of being hit by the table.

SC out of adjustment too far out:

1. 1st ball - sweep down, table down about halfway and stops. Table will not move by lifting TA or SA.









brief outline ready for corrections/additions/deletions from all.

In 20+ yrs. I've never had an interlock problem from the TB or SC. ( yes the interlocks are when they are both out) Most if not all are from the breaking curcuit. ( westinghouse)

SB, Also

SB, Also

That's funny, I was going to edit and say, and an occasional cam switch.

AMF's switch tester makes the job alot easier.

Never heard of it, please explain.

Regarding TA2, if the lever is out too far the sweep will never leave guard. On first ball cycle start SS chassis if SC is lifted off the switch either because the screw is out too far or the sweep coasts past guard enough after the delay both sweep and table will run/interlock.

Good old Aussie invention that one ... BRILLIANT DEVICE.... had one in EVERY centre I worked in with SS chassis'.......
