1.1. Description of the transmitter CA310 transmitter can be configured via the keypad. It is possible to set the measurement units, to activate or not a channel... Principle: the different settings are in the form of folders and sub-folders numbers. The digital codes are fully detailed in this manual.
2.1. Configuration of parameters Communication speed: between 2400 and 115200 bauds, 19200 bauds by default • Data bits: 8 bits • Stop bit: 1 bit • Parity: None • Flow control: None • Transmitter addressing: between 1 and 255 (automatically answers the requests from address 0) •...

This step is compulsory for each configuration. First, to access to the transmitter functions, and for safety, a safety code must be entered. The default safety code is 0101. The transmitter must be energized. • ➢ Connect the transmitter. ➢ Wait until the initializing period is over. ➢...
This folder allows to configure the following parameters of the transmitter: safety code, modbus, options and factory configuration. It also indicates the serial number and the firmware version of the transmitter. 4.1. Access to the serial number: F100 The serial number allows to get activation codes for the options. F 100 is displayed (see previous page).
4.5. Configure the Modbus communication (optional) Modbus option must be activated (see chapter 4.6). 4.5.1 Set the slave number: F150 F141 sub-folder is displayed. ➢ Press + key. “F 150” is displayed on the main screen. ➢ Press OK. “F150” blinks on the second screen and the slave number is displayed on the main screen (ex: 255). ➢...
“F170” blinks and “1” is displayed on the main screen, meaning the option is activated. - Modbus option: F171 ➢ Go to the F171 sub-folder and perform the same procedure as for high resolution option. - Air velocity and air flow option: F172 (this option is only available with a pressure board type SPI-2) ➢...
This folder allows to activate the channels and to set measurement unit for each channel. 5.1. Activate a channel The transmitter is powered on. ➢ Press OK. ➢ Enter the activation code (see page 8). ➢ Press OK. ➢ Press + key to go to F200 folder. ➢...

➢ Press + and – keys to go to the 1 segment of the following digit once the 1 digit is configured. The new measurement unit can have a maximum of 4 typefaces. Order of turn of the digits segments: List of available units: °C °F...
CA310 transmitters have 3 analogue outputs, 2 digital inputs/outputs as option and 3 analogue inputs as option with the MVA board. With MVA board: analogue inputs are activated and analogue outputs are deactivated, so this is the inputs that have to be configured. Without MVA board: analogue outputs are activated and analogue inputs are deactivated, so this is the outputs that have to be configured.

6.1. Set the analogue inputs and outputs The transmitter is powered on. ➢ Press OK. ➢ Enter the safety code (see page 8). ➢ Press OK. ➢ Press + key to go to F300 folder corresponding to the analogue output of the channel 1 then press twice OK. “F300”...
➢ Press OK when the last figure is configured. F 302 blinks, the high range is configured. To set the low and high ranges of the channel 2, go to the folder F311 (low range) and F 312 (high range) and follow the setting procedure of the channel 1.

New displayed value = [((10 - Coef.) x New Value) + (Coef. x Old value)] /10 Example: CA 310 (0-1000 Pa) – Current measurement: 120 Pa – New measurement: 125 Pa The pressure source being stable, the user selects a low integration. Integration: 1, maximum admitted variation ±10 Pa.
➢ Press OK. ➢ Press + key to go to F500 folder. ➢ Press OK. ➢ Press + key to go to F510 folder. ➢ Press OK. The duration between 2 self-calibrations is displayed. ➢ Set the duration with + and – keys. This delay time must be between OFF (no self-calibration) and 60 minutes.
This part allows to set the following parameters: for an air velocity and airflow probe: (hotwire or vane): the type of section, the correction factor, the integration • in air velocity and the compensation in atmospheric pressure (only available for hotwire probes) For a pressure board: air velocity and airflow (if the option is activated), the integration in pressure.
