PID adjustment range
The PID is a system for adapting the heating power in the coffee boiler.
The goal is to have a better stability of the T ° in the coffee boiler
Principle of operation:
Every 2 seconds, electronics evaluates the power to provide to the heater. This calculation is performed in a
working range of 5 ° C around the setting temperature (range = 5 ° C). Beyond that, the machine is full
power.
This calculated power is depending on the measured temperature weighted by 3 coefficients:
•
Where is the temperature: Kp
•
At what speed is changing the temperature: Kd
•
How has evolved the temperature since the beginning: Ki
This gives a percentage rise of full power given to the heater. And It’ shown by the blinking leds on the solid
state relays.
It is recommended to keep the default settings.
•
PID system is a compromise between SPEED and PRECISION.
•
The aim is to limit overruns while maintaining accuracy, speed and robustness.
Filling up Time out adjustment:
It allows to allocate to the machine a maximum permissible time for filling the boiler.
Beyond this time, machine stops and an alarm message is displayed.
The values are in seconds.
The setting is made with + and – key.
To exit, press MENU, or wait 30 seconds.
Water softener:
This menu concern the water treatment parameters. We define the alarm threshold before changing the filter
(0 to 9999 litres).
The amount of water consumed includes:
•
The water passes through the coffee flowmeters.
•
The water enters the steam boiler
The setting is made with + and – key. (Hold the key for 5 seconds
scroll faster)
To exit, press MENU, or wait 30 seconds.
When the water volume consumed is reached, the display shows:
To reset the counter, when the filter has been changed: see chapter “reset counters”
Total coffee:
This Indicate the total number of products ( tea) produced since the installation of the machine.
This counter is not resetable.
