Type of change = Next failure

Release date = 28 Aug 02

Component

Spiral and customer punches

Problem

• In the Lotem Spectrum, the proof loading arm collides with the punch cover(s) during loading.
• In Lotem 800 machines that have the 0.15 mm Plate Support Kit installed, plates often collide with the punch covers, and the plate loading tolerance for adjustment is very small.

Solution

Installation of a smaller punch cover assembly (9 mm smaller from front to back, as shown below) on each punch.

• In the Lotem Spectrum, the smaller punch cover assembly enables the proof loading arm to move up and down without colliding with the punch cover(s).
• In the Lotem 800, installation of the smaller punch cover assembly provides 9 mm of additional space in front of the punch cover. This space creates a wider range for adjustment of the “X On Wheel” parameter to prevent 0.15 mm plates from colliding with the punch cover(s).

Time needed to implement

30 minutes

Procedure

This procedure includes the following steps:

• Pre-installation site inspection
• Installing the punch cover assembly

Pre-installation site inspection

Before implementing this FCO, you need to go to the customer site to verify installed punch type or types. Then, order the punch cover assembly or assemblies required, as detailed in Parts needed.

Installing the punch cover assembly

1. Open the front door.
2. Disconnect the punch detector wiring on each punch.
3. On each punch, remove the two punch cover securing screws (shown below) and lift the punch cover off of the punch.

4. On each punch, place the new punch cover assembly on the punch and secure it in place using the two screws that you previously removed.
   Note: Be sure to apply Loctite™ 242 to each screw.
5. Reconnect the punch detector wiring.
6. Test functionality and adjust as required, as described in Test & Adjustment Procedure in FCO 27707 A & B.
