Details
:
1). Power for the timer needs to be connected to terminal 9 and 10. The
voltage should be in the range from 90 to 260 VAC.
2). Terminal 6, 7, and 8 are for relay output. Pin 6 and 7 is a pair of normally-
open (NC) contacts. Pin 7 and 8 is a pair of normally-open (NO) contacts. The
relay is a “dry switch” that does not provide power by itself. Please see the
wiring examples in Section 9.
3).
Terminal 5 is the start terminal that has the same function as the
START
key on the front panel.
Please see a note at the end this section.
4). Terminal 4 is the pause/mute terminal that function the same as the
“
^/MUT
” key on the front panel.
5). Terminal 3
is the reset terminal that function the same as the “
V/RST
” key in
the front panel
.
6). Terminal 1 is the common contact for the terminal 3/4/5. Terminal 2 is
unassigned. There are two ways to operate terminal 3, 4 and 5:
6.a) Connecting a normally open (NO) momentary push button switch between
the terminal (3, 4 or 5) to the COM (1). Please note, the function starts when
you release (or open) the button of the switch, not when you press down the
switch.
6.b)
Connecting a DC logic signal (TTL or CMOS or voltage in the range from 3
to 30 VDC) between the terminal (3, 4 or 5) to the COM (1). Please note, the
function is rising-edge triggered. The logic signal should normally be at high
level. The function starts when the signal goes from low to high. If you have an
inverted logic signal, you need to connect a NPN transistor between terminal
and COM; add 10 kohm resistor to the gate for signal input.
5. Operation and Parameters
In JSL-73B timer, an event is defined as an action of adding an ingredient at a
specific time point during the wort boiling process. An event timer starts from
the moment that the ingredient is being added to the wort; it stops when the
wort-boiling process comes to an end. There can be multiple events during the
wort-boiling process. Each event should have a different starting time point, but
they all end at the same time, which is when the boiling process ends.
The top display window will show the remaining time before the next event, i.e.,
when the next ingredient should be added to the wort. The lower window will
show the remaining time to the end of the wort-boiling process. The alarm relay
will pull in when a new event timer starts or when all events end.
Please see Figure 3 for a schematic diagram showing the relationship between
multiple events and the alarm relay status.
Figure 3. A schematic diagram of how the event timers and the relay work on
JSL-73B timer.
A special case of the timer is to set it as a stopwatch. In this case, each
window will show a count-up timer. There is no ending point and the relay won’t
pull in. The timer showed in the top window can be re-started while the timer in
the bottom window is still running. The details can be found in section 5.2.

nE
, the total number of events. An event can be associated with an activity
such has adding hops or special ingredients. Each event has its own timer.
nE
can be set to a number from 1 to 9. The output relay will pull in at the beginning
of all events except the first event, and at the end of the entire boiling process.
So
nE
is equal to the total number of times you want the buzzer to ring. For
example, if you only add hops at the very beginning of the boiling process, and
