Kimo C310 User Manual

• Auto (probe 1) : the transmitter will take into account the measured temperature by a temperature probe
connected to the transmitter at the location “Probe 1”.
➢ Go to “Atmo pressure” line then select the unit with Up and Down keys.
➢ Press OK.
➢ Enter a value. This value must be between :
• 0 and 4000 hPa
• 0 and 4000 mbar
• 0 and 3000.24 mmHg
• 0 and 10 000 m (altitude)
The default atmospheric pressure is 1013.25 hPa.
Enter an integration in pressure :
➢ Press OK.
➢ Enter the security code then press OK.
➢ Go to the “Parameters” line then press OK.
➢ Go to “Board” line then press OK.
➢ Go to “Pressure integration” line then press OK.
➢ Use Up and Down arrows to select an integration then press OK.
The pressure integration must be between 0 and 9.
Enter the time-delay between two autozeros : Thanks to the temperature compensation of the gain (from 0 to 50°C) and
to the autozero system, Class 310 transmitters guarantee an excellent long-term stability, along with a great measurement
accuracy.
Autozero principle : the microprocessor drives a solenoid valve that compensates for any long-term drift of the sensitive
element.
Compensation is made by regular automatic adjustment of the zero. True differential pressure measurement is then made
regardless of the environmental conditions of the transmitter.
➢ Press OK.
➢ Enter the security code then press OK.
➢ Go to the “Parameters” line then press OK.
➢ Go to “Board” line then press OK.
➢ Go to “Autozero” line then press OK.
➢ Enter a duration with Up/Down/Left/Right arrows then press OK.
- The autozero duration must be between 0 and 60 minutes.
- The default autozero duration is 10 minutes.
Set the purge time : 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 activate the relay 2 in order to isolate the transmitter.
Here is the detailed process of the purge mode :
• 1 – Measurement is frozen.
• 2 – Wait for 3 seconds.
• 3 – Activation of the relay 2 (isolation of the transmitter).
• 4 – Wait for time-delay (e.g : 10 seconds).
• 5 – Activation of the relay 1 (sending compressed air into the network to clean the installation).
• 6 – Purge duration (e.g : 30 seconds).
• 7 – Deactivation of the relay 1 (stop sending compressed air).
• 8 – Wait for time-delay (e.g : 10 seconds).
• 9 – Deactivation of the relay 2.
