PROGRAMMING - PROCEDURES (continued)
Factory Settings
The factory settings menu can
only be accessed by going into
the programming mode:
Press and hold the 4th and 6th
keys for 3 seconds until the
LCD reads “BREW SETTINGS”.
Then, press the 1st key until the
LCD reads “MACHINE
SETTINGS”; then,
Press and hold the 4th and 6th
keys for three seconds until the
LCD reads “FACTORY
SETTINGS”.
Only qualified personnel should
make changes to these settings.
Timer Status 1:
If set to “1” the
timer will automatically turn the
machine on and off, until the
“OFF” key is used to turn it off.
The machine will then remain
off until it is manually turned on.
Timer status 1 should only be
used in circumstances where
the machine will not get turned
off accidentally. (Manual OFF
overrides Timer)
Timer Status 2:
(Factory
Setting.) If set to “2” the timer
will automatically turn the
machine on and off. If the
brewer is turned off manually it
will remain off until the next
scheduled on time; or if it is
turned on manually it will remain
on until the next scheduled off
time. (Timer overrides manual
ON/OFF).
·
“InflRate:” – Inflow Rate.
The inflow rate is factory set at
0.70 gallons per minute. This value is required to calculate
the water volume. Generally the 0.70 setting will be quite
accurate unless there is unusually low or high water pressure
and volume, in which case the Inflow Rate can be changed.
·
“Calibration”
. To access the calibration program press the
4th key when “Calibration” is on the screen. The probe is
factory set and should not need resetting, unless the control-
ler board or probe is changed. See Calibration Instructions
following the Factory Settings menu items for detailed in-
structions.
·
“TotalVol:” – Total Volume.
Total water volume is stored in
the Factory Settings menu as well as in the Service & Count-
ers menu. This total is not re-settable.
·
“BrewCycs:” – Brew Cycles.
Total brew cycles is stored in
the Factory Settings menu as well as in the Service & Count-
ers menu. This total is not re-settable.
·
“InletValvTime:” – Inlet Valve Time.
The inlet valve time is
important to gaining proper brew volume in varying water
pressure and flow conditions. When the water in the tank
drops below the liquid level sensor, the inlet valve will come
on and fill to the sensor (which will take a few seconds due to
meniscus) then continue filling for the number of seconds
programmed for the INLET VALVE TIME. The factory setting
is 3 seconds that will cover most conditions. However, if wa-
ter pressure and flow is low increase the value to 6 or 7 sec-
onds. Conversely if pressure and flow are high decrease the
setting to 1 or 2 seconds. See Adjusting “Inlet Valve Time –
Determining Pressure and Flow” below for more details on
how to get the proper setting for specific water conditions.
·
“Valve Delay”.
The valve delay time is the amount of time to
delay turning on the inlet valve after water has dropped below
the liquid level sensor. Factory setting for this is “0” seconds.
·
“Timer Status”.
If the timer (in the Time Functions Menu) is
on, this setting can be used in two different ways.
