408 and 2404 Controller

NEW SLEEVE DESIGN MKIII

From Jan-03 an improved design of 1/8 DIN long sleeve is shipped with all new 2408

controllers and indicators. (The month and year of manufacture are shown in the last two

pairs of digits of the instrument serial number).

Details

A new sealing gasket will be fitted onto the instrument bezel !. This gasket replaces the

gasket which was moulded into the front of the sleeve of all previous instruments.

The gasket previously moulded into the sleeve where it fits behind the panel is now supplied

as a separate item ".

Reasons for the Change

This change is to ensure that IP65 sealing is reliably achieved and less physical effort is

required to insert the instrument into the new sleeve.

Recommendations

1. An instrument delivered after Jan 03 should be used with the sleeve supplied

2. If the instrument is required to replace one already in use, the existing sleeve should

also be replaced

3. A new instrument can be fitted into an existing sleeve by carefully removing gasket

! but IP65 sealing will not be maintained

4. An existing instrument can be fitted into a new sleeve but IP65 sealing will not be

maintained

It is, however, possible to achieve IP65 sealing for 3 and 4 above. A gasket kit is available by

quoting Part No SUB24/GAS2408.

Then:-

5. To fit a new instrument in an older sleeve carefully remove gasket !. Replace it

with the thinner (1.25mm) gasket from the kit

6. To fit an existing instrument into a new sleeve fit the thicker (1.6mm) gasket from

the kit between the instrument and the sleeve

The seal " supplied as a separate item with a new instrument, should be placed over the

sleeve prior to mounting it through the panel cut out as shown below:-
