Installation Instructions

Receiving the Shipment

1. If this is your first time setting up the Elemental Machines system, you will receive an email for your dashboard account verification. Save this email for when the devices arrive.

2. When devices are shipped, they will be added to your Elemental Insights Dashboard with default names. When you first log in you will see all your devices with a 'disconnected' status.

3. When devices arrive, carefully remove the contents from the packaging. If any of the contents look damaged, please send a picture to help@elementalmachines.com.

4. If you have ordered multiple Element-B’s, ensure the Element-B being used is configured as Normally Closed (NC). This can be verified by checking the device label, the dashboard under ‘Machine Model’, or the packing list sent with your shipment.

a. Element-B’s can either be configured as Normally Closed (NC) or Normally Open (NO) by our team here at Elemental Machines. Different assets require different configurations. If you have ordered Element-B’s for multiple assets, you may have a mix and need to be aware of attaching the correctly configured device to the correct asset.

5. Ensure there is an Elemental Machines Gateway set up in the vicinity of the Element-B.

a. Depending on your location and application, your Gateway type may vary. Please follow the setup instructions in the relevant Element-B User Manual, GW2 User Manual, or GW3 User Manual.

b. Note: ‘Vicinity’ is within wireless connection range. This is usually up to 30 meters but can depend on the lab’s layout.


Attaching Connection Cable to Asset

6. Open the monitor housing by turning the latch as labeled on the device.

7. Verify the DIP switches are in correct positions as shown below and in the manual. For oxygen monitors, ‘warning’ must be set to ‘negative action’ (the default setting). This is controlled by SW2 number 7. This switch should be in the OFF position (LEFT) as described in the manual.

8. Locate the terminal block labeled ‘WARNING’ (see Figure 3). Loosen center and right slots of the terminal blocks to accept Element-B wires.

9. Pass the provided cable through one of the existing cable glands/ports available on the Toxgard II. Then insert leads into open terminal block connections and tighten the screws. (Either wire can go into either slot.)


Available ports may vary depending on the original installation process. See Figure 4 below for example:

10. Make sure the wires are securely held in the slots.

11. Once cable has been connected, port should be re-covered. Provided cover may need to be modified to fit alarm cable, at installers’ discretion.


Attaching Connection Cable to Element

12. Per your discretion, write the name and/or location of the equipment being monitored on the Element-B. This can be particularly helpful if multiple devices are being installed. Use of a Sharpie is recommended.

13. Plug the thermocouple end (Figure 5) of the connection cable into the Element-B.

a. Note Ensure the (-) and (+) prongs of the thermocouple end are properly matched.

14. Pull the battery tab on the Element-B.


Positioning the Element-B

15. Determine where the Element-B should be placed so that it is not blocked, which allows a better wireless connection, and so that the connection cable is tidy.

16. Securely position the Element-B in the chosen location. The Element-B has magnets which make it easily mountable to magnetic surfaces.

a. Note: If applicable, an adhesive metal mounting plate available from EM may be used.


Programming Alerts

17. Program alerts on the gas monitor, as desired. Refer to the Toxgard II user manual for default conditions that trigger the WARNING relay (<18% oxygen) and for additional information on changing parameter settings.

18. Set up alert rules on the Elemental Insights Dashboard™ for the Element-B. Guidance on how to do so is available in the Support section of the dashboard.

NOTE: Alerts must be programmed on both the Toxgard II Oxygen Monitor and the Elemental Insights Dashboard™ to receive remote alerts through the Elemental Machines platform.
