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 c. 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 d.
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
c 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 c. 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 d 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:-
