After changing the battery, the meter will log the status of ‘cover open’ and ‘battery’ in the form of flags.
The old battery must be disposed of in a suitable manner in accordance with local
legislation.
The battery can only be replaced by a type and manufacturer approved and recommended by Secure Meters,
fitting an unapproved battery will be in breach of the regulations set out by the ATEX directive and will
invalidate the products warranty. The primary battery must only be of any one of the following types:
EVE part number ER34615
Vitzrocell part number SB-D02 CON
Tadiran part number TL-4930
Xeno part number XL-205F
Step 4: Remove the front cover and then disconnect the battery
by unlocking the battery connector.
Step 5: Replace the old battery with the new battery and
connect it by aligning the connector clip with the arrow on the
meter body. During this process ensure that the special nuts,
gaskets and rubber plunger are handled carefully, and they are
back in their original position after assembly.
Note: If this operation is carried out at the installation site,
then the new battery must be fitted within 10 minutes.
For test station use, where the meter has been disconnected
and purged, the battery can be replaced any time after
disconnection.
Step 6: Ensure that the battery connector is connected correctly
and the rubber plunger is in place with the front cover. Put the
front cover back on the unit and secure the M4 screws tightly at
1.2 Nm torque. To avoid any damage to the plastic parts, the
new seals should be press-fitted to seal the battery
compartment.
