Programming
5.1
User interface
Digital display panel
•
The digital display panel normally indicates a temperature in °C or °F depending on the LEDs indicating the
measurement unit selected.
•
During programming and as stipulated by the parameter selected, it indicates the value of the parameter
in °C, °F or seconds.
•
When the first digit point is blinking, that means the sensor is in default (cut or short circuited). When the
second digit point is blinking, that means the sensor temperature measurement is out of the range the
electronic card can read.
Buttons
5 buttons are used to visualise and modify the various parameters of the Mastéria unit's electronic regulation.
LEDs
4 LEDs indicate the operating condition of the drier or the regulation.
5.2
Changing set points
General
The factory-programmed set point normally meets the nominal capacity of your drier and is also appropriate
for all the flows lower than nominal. A change of set point may be necessary to obtain a dew point higher
than the standard dew point to authorise flows higher than nominal capacity or in a particularly hot
environment.
Adjustment
•
Press button for 15s.
The set point flashes on the digital display panel.
•
Use the buttons to modify the set point
The adjustment range is from 0 to 10 °C (32 to 50F°)
•
To record the new value, wait 5 seconds without pressing a key. The digital display panel reverts to its
normal status (i.e. stops flashing) and indicates the variation between the measured value and the set
point.
