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.

Before connecting power in an explosive atmosphere, ensure the instrument is installed in accordance
with intrinsically safe or non-incendive eld wiring practices.
Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous
locations certications.

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.
