To Install a Module:
Installing a module is a bit more complex because you first have to be sure the locking
screws are aligned correctly. The following procedure is suggested.

Verify that the correct shutter setting has been selected on the rear of the
Controller. Refer to Table 13 on page 97.

If you are using a 25 mm remote-mounted shutter and it suddenly stops
running, its built-in thermal interlock may have been triggered. Stop the
experiment and wait. The shutter should resume functioning when it has
cooled down sufficiently, typically within an hour. Avoid repeating the
conditions (such as high repetition rate) that lead to the shutter overheating,
or take breaks between data collections.
•
If the shutter no longer operates at all, sticks open or closed causing
overexposed or smeared images, or a shutter leaf has broken and no longer
actuates, contact the factory to arrange for a shutter-replacement repair.
