1.a - Working principleUsing keypad / remote control / Modbus configuration, you can activate (or deactivate) a channel, change themeasuring range, set the set points and time-delay...
Principle: the configuration options are accessed via folders and sub-folders (similar to Windows ). Access ismade via a numerical code (full details in this manual).
Meaning of the keys
To increment a value or a level
To decrement a value or a level
To validate an input
To cancel an input or to return to the previous step

It's extremely unwise to remove the protection tip of our hygrometryprobes as the sensitive element is very fragile even to light contacts.However, if you have to remove the protection tip, take all possible
precautions and avoid any contact with the sensitive element.
To remove the protection tip, unscrew it or unclip it.

7.e - Alarm mode details
7. Alarm / relay settingsF400
7.e.1 - DefinitionsSetpointThe 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 ashort period (in seconds). Once this period is elapsed, and if the setpoint is still exceeded, then the alarm is activated orthe 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 overthe setpoint Falling action: the alarm is activated once the measurement goes below the setpoint

!You must enter values according to the units of measurement selected, notaccording to the measuring range of the transmitter.
Ex. on a CP 303 pressure transmitter (0 to 1000 Pa) with a reading in mmH2O, the minimum and maximum ranges must beconfigured on measuring range of 0 to 102 mmH2O. See conversion chart on page 13.
If after having set up a setpoint, the unit of measurement is modified (see page 9), then you have to reconfigurethe setpoints according to this new unit of measurement.

Page 33Class 300 transmitters configuration via keypad / remote control / modbus
The purge mode enables to freeze the measurement when being displayed, enables to lock the analogue outputs,and to activate the relay 1, in order to actuate a de-dust system of an air movement conditions system and to activatethe relay 2 in order to isolate the transmitter.
! This function is only available on CP 300 pressure transmitters.
Here is the detailed process of purge mode :1 - Measurement is frozen.2 - Wait for three seconds.3 - Activation of relay 2 (isolation of the transmitter)4 - Wait for time-delay (e.g : 10 seconds).5 (sending compressed air
into the network to clean the installation)6 - Purge duration (
- Activation of relay 1
(e.g : 30 seconds)
7 - Deactivation of relay 1 (stop sendingcompressed air).
