Introduction
This article provides instructions on how to replace a Cordant Edge battery in a Ranger Pro endpoint (EP). This hardware is used in hazardous environments up to Class 1 Div 1 or Zone 0/1, and is manufactured by Baker Hughes.
When to replace a battery
Change the battery if the EP is in a low or drained battery status on the IoT health tab on the web platform.
Before you begin
Caution!
Are you working in an explosive (hazardous) environment (CI-D2, CII-D2 ATEX Zone 2, CI-D1)?
Areas are specified as hazardous when they contain (but not limited to) the following three fundamental components:
A flammable substance (which can be a gas, liquid, or solid)
An oxidizer
Any source of ignition
If the environment is hazardous, install the battery outside that area.
Make sure that you fully understand the required Hazard training, certification, and equipment needed to comply with state requirements, and that you follow the safety precautions.
You must follow Augury procedures when removing and remounting the EP.
Follow the safety precautions required by your area/plant when working on or near an operating machine.
Do not attempt to fix an EP installed on any equipment while near any exposed hazards. Personal protective equipment should always be worn.
Use only the batteries that come with the Augury Ranger Pro battery kit! Note that the Kit and battery PNs may vary.
Do not open sensors inside a hazardous area. If a battery needs to be replaced in the field, remove the entire sensor from the equipment and take it to a non-hazardous area to perform maintenance activities.
It’s important to note that the battery removal tool contains a powerful magnet. Keep the tool away from the gateway otherwise the gateway might reset itself to factory settings.

Use only approved D-size lithium-thionyl chloride batteries for the Ranger Pro sensors and repeaters. If you use the wrong battery, you can negatively affect device performance, produce inaccurate readings, and void the Ranger Pro warranty.
Remove the old battery
1: Remove the endpoint from the machine and take the endpoint outside the explosive environment to replace the battery.
2: Remove the e-module retaining ring. Turn the e-module retaining ring counterclockwise and stop when resistance decreases. Place the device on a flat surface. Use your index finger and apply firm pressure to the top of the e-module. Use your other hand and continue to unscrew and remove the retaining ring.
3: Remove the wireless e-module. Hold the device with the contactor pins of the e-module facing away from you. Using the thumbs of both hands, push the e-module IN and UP simultaneously.
4: Remove the battery retaining ring. Use the battery installation tool to remove the battery retaining ring. Turn the ring counterclockwise. Use the magnet in the tool to lift the ring from the device case.
5: Remove the old battery.
Install the replacement battery
1: Inspect the interior threads of the e-module retaining ring to be sure they are not damaged. If they are damaged, you need to replace the entire endpoint.

2: The Ranger Pro device uses two O-rings to seal the unit against dust and moisture. To maintain the device’s IP67 dust and water resistance rating and prevent leaks, you must install and lubricate new O-rings properly.
Remove the O-rings and replace them with new O-rings. Apply a very light coating of silicon-based O-ring grease to the O-rings.
There are two O-rings:
34 x 1 mm O-ring on the e-module
35 x 1mm O-ring on the case
3: Make sure the battery’s positive end is facing up before inserting the battery.
Caution: Use only approved D-sized lithium-thionyl chloride batteries for the Ranger Pro sensors.
4: Use the magnetic Ranger Pro battery installation tool to tighten the battery retaining ring. Hand tighten the ring until it contacts the battery, then torque to 5 N-m (44 in-lb).
To maintain the device’s IP67 rating, be careful to avoid damaging the O-rings. Turn the e module retaining ring clockwise two to three turns, and then counter-clockwise about ¼ turn, and repeat until the ring is hand-tight.
5: Align the e-module retaining ring over the e module. If needed, hold the sensor in place with your finger.
6: Verify that the device is tightly sealed. There should be no gap between the e-module retaining ring and the case, as shown here.
7: Check the endpoint connectivity using the Cordant System Manager.
8: After replacing the battery, resolve the battery alert in the Augury web platform.
