Changing the battery box can be performed in the field as the Swarm S2 Datalogger can be opened in Hazardous
environment since it is intrinsically safe. When opening the lid, the power from the battery is disconnected and the
unit is powerless even if the battery connector is still connected.
Open the top lid by:
1) Unscrewing the two Hex 6 bolts
2) Pulling the top lid carefully straight
upwards until the connector releases and
is free
3) Tilt the top lid over the edge and it will
remain there fixed in the rubber hinge
4) The hex bolts are held in place by
retaining washers.
Release the connector in the top lid by pulling it
gently backwards and pressing the locking flaps
simultaneously.
When reconnecting the battery box make sure
that the slots on the connector (indicated by the
arrow) is facing downwards towards the circuit
board in the top lid.
You can now take out the battery box
Grab the battery box with your thumb and index
finger pull firmly upwards to release the battery
box.
Insert a new battery box in the reverse order, connect the battery connector paying attention to its
direction. Close the lid.
Make sure the O-ring seal in undamaged and in place when closing the lid and tighten the bolts hand tight.
Inspect the joint between the main body and then lid to ensure it is sealing correctly.
