5.1 How to Set the Timer and Dose Time T1/T2.
When timer is not running,
in single/double dose display mode,
a) P
ress “SET” key to shift between single dose time T1 and double dose time
T2. When parame
ter “tAdJ” is programmed to “ON” (see definition of “
tAdJ
” in
next section), simply press up/ down key will increase/decrease the set value
of each delay time. (Hold up/down key will increase the changing speed
exponentially).
b) Hold “SET”
key for 3s, the display will change to total running time/cups
display mode. For how to program two different display modes, please see the
d
efinition of “
dISP
” in next section.
c) H
old “SET” key for 5s, th
e display will enter parameter programming menu.
5.2 Definition of Programming Values.
trnG: timer range.
S: 0.01 s ~ 99.99 s.
M:S: 1 s ~ 99 m 59 s.
tdir: timing direction.
up: counting up.
dn: counting down.
*Note: the timing direction can only be changed in the single and double dose
timer display. The manual control always counts up so that user can use its
value to fine tune the single and double dose setting.
tAdJ: time adjust.
On: When timer is not running, adjust timer directly by pressing up/down key
from the front panel.
Off: Values for timer T1/T2 are locked.
dISP: display mode.
Tot: total time (unit: second).
CUPS: number of cups.
*Note 1: in Tot mode: total time will only display integer part; when manual key
is pressed and held, the running time is counted into total time until the manual
switch is released.
*Note 2: in CUPS mode: number of cups will not be counted into total number
when manual key is pressed.
*Note 3: press down key for 4 seconds will reset the display to zero in both
modes.
tLA: constant A.
tLb: constant b.
These two constants are used for converting the total time display to other
units, such as weight in grams.
dISP = T x A/b,
where T = T1 or T2. For example, if grind 1 gram of coffee takes 2 seconds, set
A = 1, b = 2, this will convert the total display unit from second to gram.
6. Wiring Examples
6.1 Wire JSL-
72 timer as Auber’s
J72BX -- Coffee Grinder Timer Controller.
To make a control box similar to Auber’s J72BX for grinder, please refer to the
wiring diagram in Figure 4. PLEASE NOTE: this setup is only suitable for
grinders with motors that consume less than 300 W power.
