Frequently Asked Questions - SiC320 Sauermann

How to connect a probe to the SiC320?

Present the probe connector with its arrow and padlock facing the sensor-transmitter connector. Push until you hear a click. To disconnect, turn the ring to the left and remove the connector.

What quantities can the SiC320 measure?

It measures differential pressure, temperature (Pt100 and thermocouple), hygrometry, air quality (CO, CO₂, VOCs), air velocity, air flow and air change rate.

What is the required power supply?

The device operates on 24 V DC or 24 V AC with a power converter. A switch or circuit breaker upstream is mandatory.

How to configure a measurement channel?

Connect a probe, press 'Next', select the channel from the list, then press 'PROBE 1', 'PROBE 2' or 'MODULE'. Set the parameters and confirm. For models without a screen, use the app.

How to configure an analog output?

Press the output to configure, activate it, set the type (current or voltage) and the min/max values of the range. For models without a screen, use the app.

What is the protection rating of the SiC320?

The protection rating is IP66, making it dust-tight and protected against water jets. It also resists VHP (vaporized hydrogen peroxide).

How to perform wall mounting?

Attach the stainless steel plate to the wall with the provided screws and wall plugs (drilling Ø8 mm). Insert the sensor-transmitter into the plate by tilting it, then rotate it clockwise until it clicks. Lock with the fixing screw.

What electrical connections must be followed?

Only a qualified technician can perform the wiring, with the device de-energized. Follow the diagrams in the manual: power supply, analog outputs, RS-485 and probe connections.

How to maintain the SiC320?

Avoid aggressive solvents. When cleaning with formaldehyde-based products (parts or ducts), protect the device and its probes.

4. Mounting

To install the transmitter on a wall, fix the stainless steel plate to the wall (drilling: 08mm , screws and wall-plugs supplied). Insert the transmitter on the plate (see A on the drawing below) by aligning it at 30^ . Rotate the housing in clockwise direction until you heard a "click" which confirms that the transmitter is correctly installed. Open the housing, lock the clamping system of the housing on the plate with the screw (see photo below). To remove the transmitter from the fixing plate, do not forget to remove this screw.
