2. If the water needs to be heated, a signal from the controller is sent down
the Comms. link to the I/O board (heater on signal). The I/O board then
switches a 24 volt negative output to the solid state relay. The solid state
relay then switches a 240 volt supply to the heater element. The element
then starts to heat up the water.
N.B. Heater element fitted to the heater tank of instant/freshbrew
machines is rated at 2.4kW. Heating element fitted in the pressure boiler
of espresso machines is rated at 2kW.
3. This process continues until the water has reached the temperature which
has been set in the temperature configuration program.
4. Instant & Freshbrew Machines: If the water in the tank should
overheat and boil over, a high temperature cut out, positioned in the
overflow pipe, will cut off the mains supply to the heater at approximately
90°C within 60 seconds.
5. When the maximum ‘set’ temperature has been reached the ‘heater on
signal’ is removed from the Comms. link, switching off the 24 volt negative
output from the I/O board and switching off the solid state relay and the
heater element.
6. B2C Machines: Whenever a drink is selected the water is heated in the
pressure boiler throughout the vend.
