4 MAINTENANCE
The only field maintenance required on the SELD-
103 unit is replacement of the battery. The SELD-
103 can also be turned off when not in use for
extended periods of time to conserve battery life.
4.1 Tools required

Allen Wrenches (1/8” and 3/16”)

Tools required to install the various mounting
configurations are conditional based on the
type of mounting and location

Phillips head torque screw driver
4.2 Turning unit on/off
To power off the SELD-103 unit remove the
magnetic set screw at the bottom of the base. This
will stop sensor readings and data transmission.
To power up the SELD-103 unit again, simply
install the magnetic set screw at the bottom of the
base. This will activate sensor readings and data
transmission at the pre-configured intervals.

4.3 Battery Replacement
EXPLOSION HAZARD: The unit must be
powered OFF during the battery installation & must
be in a General Purpose Classified Area to prevent
the possible ignition of a hazardous atmosphere.
WARNING STATIC HAZARD: Wipe only with
a damp cloth due to electrostatic discharge hazard.
The substitution of components may
impair intrinsic safety.
Power is provided by a lithium battery pack (S1-
1043), located in the inner portion of the transmitter
housing. Battery life is dependent upon data
transmittal intervals. Battery voltage should
normally be between 2.8 and 3.6 VDC. If it is lower
than this, the battery will need to be replaced. The
battery voltage can be read at the receiver or
through the PSP software when connected directly
to the SELD-103 unit (refer to PSP software user
instructions for details on how to do this).
The battery pack is NOT re-chargeable and
shall only be replaced by contacting your local
Flowserve representative (battery pack part
number S1-1043).
Perform the following steps to replace the battery:
1. Power down unit by removing the magnetic set
screw located at the bottom of the base.
2. Remove sensor cable(s) and any installed
accessories.
3. Take SELD-103 to non-classified area before
performing next step.
4. Loosen the set screw in the side of the tube
and gently unscrew the external housing (tube)
from the transmitter assembly.
