Tue 03 August 1999

News Version:

There is a new P/N for the loading cassette which includes the FCO Magnetic sensor - Loading cassette. The P/N is 507F2D449.
The P/N of the old cassette (with out the magnet sensor implemented) is 507F1L036

This FCO includes all parts needed to upgrade 3 loading cassettes and upgrade that needed for 1 Lotem.

As soon as you updating the cassette with this FCO you must update all the loading cassette that the customer has on site.
In order to implement all loading cassettes upgrade in the field we will send the FCO's to the field as soon as we have all FCO's Qty that needed .

Note: There is a new P/N for the loading cassette which includes this FCO. The P/N is 507F2D449.
The P/N of the old cassette (with out the magnet sensor implemented) is 507F1L036
This FCO includes all parts needed to upgrade 3 loading cassette and upgrade that needed for 1 Lotem.
As soon as you updating the cassette with this FCO you must update all the loading cassette that the customer has on site.

1. Reason For Change - Improve the reliability of the cassette interlock with new type magnetic sensor.
2. Description of Change - This FCO is intended to replace the existing interlock mechanism on the plate cassette.
3. Change Procedure

Required Tools:

1. Drill (electrical, air operated or rechargeable)
2. 4mm (0.157 inch) and 6mm (0.236 inch) high speed drill bits.
3. Set of Allen keys.
4. Small piece of cardboard for mixing glue.
5. 2 pieces of wood or any other material on which to place cassette.
6. locktite glue-#242.

Attaching Actuator Assembly to Cassette

1. Empty cassette from all plates.
2. Close lid and secure latches on both sides.
3. Lift cassette off of its base and place on the left side (so that right side is uppermost) on the 2 wooden blocks so that it does not press on the latch.



4. Remove cassette interlock spring.



5. Press drilling jig in place, ensure that it is flush with the outer edge and pressed down firmly.



 

6. Drill 2 holes using a 4mm drill bit. Remove the jig and enlarge the holes using the 6mm drill bit.
7. Clean the two holes from particles.



8. Ensure area around holes and inside is clean and clear of any foreign objects before adding glue.
   Clamp actuator assembly in place using bulldog clamp supplied in kit.



9. Mix required amounts of glue from both tubes on cardboard square. Ensure there is enough to fill both holes



10. Pour glue into holes and press down with wooden sticks so that glue fills the holes completely, remove excess glue that overflows.
    The initial drying period is 15minutes and the clamp must not be removed during this time.

1. For final drying period is one hour before using the cassette.
2. Implement the same process for all the loading cassettes on site. You have in this FCO’s 3 actuator assembly for 3 loading cassettes.

Installing Sensor Assembly

The installation of the Sensor Assembly comprises two steps:

• Removing Cassette Interlock Assembly from the front of the machine.
• Installing Sensor Assembly

Remove Cassette Interlock Assembly

1. Open front cover and remove upper front panel.
2. Remove upper front right side panels.
3. Remove 2 retaining screws and disconnect interlock assembly from frame.
4. Disconnect 4 cables attached to the interlock assembly.

Insert Sensor Assembly

1. Attach sensor assembly to frame using the same holes as used for interlock assembly.
   Spread locktite glue on screws before tightening (use screws provided in kit).
2. Connect cable harness adapter assembly to 4 cables from interlock assembly, connecting matching colors in each case.
   Slide also shrinks wrap casing over the cable connections. Secure the cable to eliminate damage by the loading cassette.
3. Connect cable assembly to sensor assembly.
4. Replace and close all covers.
5. Test Procedure – Open the Cassette interlock detector and check that the status of the detector is changing from off to on.

Questions & Answers

Hi All, recently we shipped the magnetic sensor to the field for upgrading the Loading cassettes.

Reason For Change - Improve the reliability of the cassette interlock with new type magnetic sensor.

The FCO P/N - 510F25560
The following comments to Ido from STA which sound like he is the first one that implement the FCO.

Since we sent most of the FCO's to the field I will use the following as comments to the entire field.

Subject: the new FCO "magnetic sensor - loading cassette"

Hi Sammy

I did today the FCO of "magnetic sensor - loading cassette" in WE and here are my remarks:

1. We need a cheater. is the red piece of metal that was attach to the kit is for the cheater? the cheater is a red bracket with a magnet. The P/N of the cheater is 507A2D738. The cheater is part of the FCO and will be  arrive with each Lotem that send from the assembly line. See the following word file for positioning the Cheater.

Magnetic Sensor cheater position.doc

If yes how to install it?, we need to add the new cheater to the "spare part on site"

2. Can we add another sensor for the 4th cassette, just in case that we have four cassette on site, it will be a waste of money to order another kit just for one cassette sensor. We already shipped all of the FCO's to the field. If you need actuator for the forth cassette (fifth ,,,) place order for 507A2D676.
3. In one of the cassette we were needed to file the cassette, to have room for the jig, I think it should be written in the procedure that if the jig is not fit you should file the cassette. O.K.
4. I think we should add another picture, of the jig mounted on the cassette, from top view.
   It will be easier to understand how to mount the jig on the cassette.
5. Between step 7 and 8, please add the explanation how to put the sensor inside the cassette, you have only picture with out explanation. Follow the arrow direction to place the magnet actuator and use the bulldog clamp to hold the actuator to the cassette.
6. Step 10, it is very difficult to clean the glue from bulldog clamp, and if you don't do it right it might glue the clamp also.
   Frank found a very nice idea, put film between the clamp and the hole, then the glue can stick only to the film and not to the clamp. Nice TIP can we change the position of the cassette from vertical to horizontal after we put the glue?, or we need to wait few minutes? if yes how long? You need to wait 15 minutes. See step 10 in the FCO doc.
   Please add this restriction, if there is any, to the procedure.
7. In "remove cassette interlock" why you need step 2 "remove upper front right side panels"?
8. The shrink that you send, were and how to warp it?, it is very difficult to slide all the four connector inside, do you what us to cut it to four pieces for each connector? please add picture
9. When we going to have NEW machine with the magnetic sensor install on them? lOTEM s/n 9938xxxxxX
10. When we going to have NEW cassette with magnetic sensor? The loading cassettes that shipped from the cassette vendor from last week 1/10/99 are already with the magnet sensor.
11. Do we going to ask the filed to do it as a mandatory FCO, so all the machine/cassette will be the same?. We are strongly recommend to implement this FCO. You can do it when you have open call, in order to reduce calls on site. (MTBV)
