Appendix G. Replacing the Battery
The battery must be replaced when its voltage is too low (battery Low or Low-
Low alarm). When the battery is disconnected for its replacement, the value of the
following parameters is saved:
Setup > Temperature Setup
Service > Sensor Param
View Readings > View History > View Sensor Card History
However, when the battery is removed, the value of the following parameters is
lost:
Setup > Alarms Setup
Setup > Date & Time
Setup > Comm Setup
Setup > History Setup
Setup > Relay Setup
Setup > I/O Setup
Alarms > Alarms History
View Readings > View History Data
To replace the battery, proceed as follows:
Note: Step 1 below can be skipped if the Hydran M2-X was never put in service
and if the Hydran M2-X’s default parameter values have not been changed.
1. Because some Hydran M2-X’s parameters are lost (see above) when the battery
is disconnected, they must be recorded. There are two methods:
Use the Perception software. For connection details, see Chapter 5; for
details on the software, see the Perception Manual.
- History files are transferred automatically as soon as the
communication is established between the Perception software and
the Hydran M2-X. The Histo Download in Progress... message remains
displayed in the Perception window during the transfer.
- Manually note all parameters in the Hydran M2-X’s Communication
submenu. These parameters are the only ones that cannot be
accessed from the Perception software.
If the Perception software cannot be used, manually note the values of all
Hydran M2-X’s parameters. This method is more difficult and can be source of
errors.
2. Power off the Hydran M2-X.
3. Remove the cover.
4. Remove the two screws holding the cover of the electronic card cage.
