Converting a High Pressure Brewer from Doser to a Timed Grind
1:
To avoid unnecessary rebooting if the machine detects
a Doser error during the conversion, you must first
ensure that the machine has a minimum firmware
version of:
Sigma Touch [03.19]
Sigma Simplicity or Café [03.05.0013]
The below instructions apply to the Sigma Touch. All the
references are also found in the same programming
areas on the Sigma Café and Simplicity machines.
Important: Before upgrading Sigma Café and Simplicity
machines, first take a copy of the config and audit files to
re-load back in after the firmware upgrade.
2:
After the machine has been upgraded to the minimum
version as above enter service mode and BREWER
SETTINGS.
You will find two new entries - one is DOSER ENABLED
and the other is the GRIND RATE. Turn off the DOSER
ENABLED tick and save settings. This will now switch off
the mechanical Doser and the HPB will no longer be
looking for the switch on power up. You can now switch
off the machine and remove the Doser Unit (the top
plate of the Brewer Module needs to be removed to
disconnect the Doser and switch cables). Keep the screw
removed that was securing the Doser to fit the new
Grinder Outlet.
3:
The Conversion Kit includes the following parts:
A – 1 x Replacement chute holder (1037406)
B – 1 x Grinder Outlet (1055002)
C – 2 x M4 Wing-nuts (1023083)
4:
Remove the current stainless steel chute and fit it to the new replacement chute holder bracket (A) above, this
will now look like this.
