1.a - Working principle
Using remote control and optional Modbus configuration, you can change units of measurement, set setpoints and
relays...
Principle: the configuration options are accessed via folders and sub-folders (similar to Windows ). Access is
made via a numerical code (full details in this manual).

6. Analogue output management
6.a - Output diagnostics
With this function, you can check with a multimeter (or a regulator/display, or a PLC/BMS) if the transmitter outputs
are working properly. The transmitter generates a current (between 4 and 20mA) or a voltage (between 0 and 10V).
6.a.1 - Multimeter connection configuration
Before carrying out the output diagnostics, all connections and configurations of the transmitter must be
enabled, to avoid any damage on the transmitter and the multimeter !
Example of
connection
On the photo alongside, the multimeter is
connected to the 0-10 V output.

7.c - Alarm / relay functions and LED colour codes
7.c.1 - Visual / audible alarms
Class 300 transmitters have 2 visual / audible alarms located in front of the transmitter, allowing to know the
condition of the setpoints.
Alarm LED colour codes
Green The alarm function is activated and
the set point is not reached
Red The alarm function is activated and
the setpoint is reached
None The alarm function is not activated
The red LED appears when the setpoint is reached,
taking into account the time-delay and the action type
(falling or rising).

Once the alarm is activated, an alarm sounds
whilst the setpoint is reached.
The BEEP alarm function must be activated to use the
audible alarm. See page 12.

7.d.1 - Definitions
Setpoint
The setpoint is a limit which, on being reached and/or exceeded , activates an alarm or energizes a relay (in negative
security, see page 14 for more details).
Time-delay
Once the setpoint is reached and/or exceeded, the time-delay postpones the alarm activation (or relay excitation) for a
short period (in seconds). Once this period is elapsed, and if the setpoint is still exceeded, then the alarm is activated or
the relay is energized (in negative security).
Action type
For alarm activation or relay excitation, you can choose the action type: rising or falling action.
• Rising action: the alarm is activated once the measurement goes over the setpoint
• Falling action: the alarm is activated once the measurement goes below the setpoint

8.a - Pressure measurement integration
+/- (
Example : CPE303 (0-1000 Pa) - First measurement: 120 Pa - New measurement : 125 Pa
The pressure source is stable, the user applied a low integration. Integration : 1, maximum variation allowed +/-10 Pa. Since the variation is less than
10 Pa, we apply the integration calculation formula. Next measurement displayed ((9 * 125) + (1 *120 ))/10 = 124.5 soit 124 Pa. If the new value had
been 131 Pa, the next value displayed would have been 100% of the new value, i.e 131 Pa.
The integration coefficient makes an average of the measurements: this helps to avoid any excessive variations
and guarantees a stable measurement.
