4. Mounting

•

Minimum nozzle diameter should be 2” from the probe at initial installation.

•

Probes should not contact metallic tank walls, obstructions or structures.

•

If using cable probes, take into account the possibility of cable sway encroaching clearance requirements of

agitators and augers. If this possibility occurs, secure a ring or mounting connection to the cable weight and

to the vessel oor.

Note: The Tek-Flex 4100A will come factory set for mounting to a metallic ange or tting unless otherwise

instructed at time of order.

Transmitters with threaded process connectors can be screwed to tanks or nozzles with threaded bosses.

Tek-Flex 4100A transmitter can be successfully installed in a new or existing bypass pipe, bridle, or a side

pipe as shown in the gure. This type of installation is often simple and allows the addition of radar level

measurement to an otherwise busy installation.



In case of non-metallic container, the Tek-Flex 4100A should be mounted with a metal plate of minimum 8”

(0.66 ft) diameter. Use metal shielding for the conduit connections.

Mounting in Concrete Silos

In case of concrete silos, the Tek-Flex 4100A should be mounted with a metal plate of minimum 8” (0.66 ft)

diameter.

7. Conguration

The Tek-Flex 4100A Level Transmitter leaves Tek-Trol’s factory pre-congured to the customer's application

settings, but if adjustments need to be made in the eld the RS485 Communication Tool is recommended.

RS485 Communication can be connected in the A & B terminals (COMMS) as shown below:

For any conguration related queries, please contact Tek-Trol technical support.

Powering the Tek-Flex 4100A for the rst time:

•

Conrm if the Tek-Flex 4100A is mounted within the recommended specications.

•

Conrm the wiring is correct and all connections are as shown above

•

Apply power to the Tek-Flex 4100A.

•

The Tek-Flex 4100A will take up to 30 seconds to warm up and stabilize upon initial start-up. It will then

perform a scan to locate the level which will take approximately 1 sec or less. Once the load sequence is

complete and the Tek-Flex 4100A has taken the rst measurement, the analog output indicates the material

level (factory default) or distance measurement. If the proper analog output is not achieved, please contact

your Tek-Trol representative for further instructions.
