Used symbols

For your safety and in order to avoid any damage of the device, please follow the procedure described in this document and read carefully the notes preceded by the following symbol:
The following symbol will also be used in this document, please read carefully the information notes indicated after this symbol:

Connections

1. DIP switch (d)
2. Pt100 terminal block
3. Solenoid valve (only on CP211/212)
4. LCC-S software connection
5. Autozero
6. Pressure connections
7. Relays
8. Analog outputs (a)
9. F3.20* fuse
10. Power supply terminal block (c)
11. Cable glands

Power supply type (b) specified on the label on the side of the transmitter

*Fuse present only for 100-240 Vac models.
Every fuse replacement must be performed with a power-off device using a TR5 630 mA 250 V fuse.
Electrical connections as per NFC15-100 standard
This connection must be made by a formed and qualified technician. To make the connection, the transmitter must not be energized. Before making the connection, you must first check the power supply indicated on the transmitter board (see (b) on the “Connections” part). The presence of a switch and a circuit breaker upstream of the device is compulsory.

• For transmitters with a 24 Vdc power supply:
• For transmitters with 24 Vac power supply:
• For transmitters with 100-240 Vac power supply:

The selection of the output signal in voltage (0-10 V or 0-5 V) or in the current (4-20 mA or 0-20 mA) is made via the DIP switch (d) of the electronic board of the transmitter: put the on-off switches as shown in the table below:

Connection of the output in current 4-20 mA:
Connection of output in voltage 0-10 V:

On 100-240 Vac models, if fuse protection is used for the power line, it is imperative to use delayed-action fuses in order to absorb the surge of current when first turned on the transmitter.

Autozero

Autocalibration
CP210 transmitters have a temperature compensation from 0 to 50 °C and an auto-calibration process that guarantees overtime excellent stability and perfect reliability of the measurement on low and high ranges.
Auto-calibration principle: the microprocessor of the transmitter drives a solenoid valve that compensates for the possible drifts on the sensitive element over time. The compensation is performed by the permanent adjustment of the zero. So the measurement of the differential pressure is then independent of the environmental conditions of the transmitter.
Advantage: no zero-point drift
Frequency of auto-calibration: resettable or from 1 to 60 minutes
Autozero
To perform an autozero, unplug the 2 pressure connection tubes and press the “Autozero” key. On CP211 and CP 212 transmitters, it is not necessary to unplug the 2 pressure connection tubes. When an autozero has been performed, “On” green light turns off then turns on, and on transmitters equipped with a display, “autos” is displayed.

Configuration of transmitters

It is possible on class 210 to configure all the parameters managed by the transmitter: units, measuring ranges, outputs, channels, calculation functions, etc, via different methods:

• Keypad for models with display: a code-locking system allows to secure the installation (See class 210 user manual).
• Software (optional) on all models. Simple user-friendly configuration. See LCC-SD user manual.

Configurable analog output:

Range with central zero (-50/0/+50 Pa), with offset zero (-300/0/+70 Pa) or standard range (0/+100 Pa), it is possible to configure your own intermediate ranges.
Caution: the minimum difference between the high range and the low range is 20.
Configure the range according to your needs: outputs are automatically adjusted to the new measuring range

Mounting

To mount the transmitter, mount the ABS plate on the wall (drilling: Ø6 mm, screws and pins are supplied). Insert the transmitter on the fixing plate (see A on the drawing beside). Rotate the housing in a clockwise direction until you hear a “click” which confirms that the transmitter is correctly installed.
Once the transmitter is installed and powered up, please make an autozero to guarantee the correct working of the transmitter in any position.

Accessories

Please refer to the datasheet to get more information about available accessories.
Maintenance: Please avoid any aggressive solvents. Please protect the transmitter and its probes from any cleaning product containing formalin, that may be used for cleaning rooms or ducts.
Precautions for use: please always use the device in accordance with its intended use and within the parameters described in the technical features in order not to compromise the protection ensured by the device.
