JSL-73B Multi-Event Timer for Beer Brewing
Version 2.1 (May, 2017)
1.
Overview
This timer is designed for home brewing when the brewer needs to follow a
recipe that calls for ingredients to be added at different time points during the
wort boiling process. It can help the brewer keep track of time and remind the
brewer to add ingredients at specific time points. The brewer can simply enter
the boiling time of each ingredient specified by a beer recipe, the JSL-73B
timer will automatically convert it to a multi-event timer whose alarm will go off
at the moment when a new ingredient should be added, as well as when the
boiling process is supposed to end. The relay output of the timer should be
connected to an external flashing buzzer which is sold separately.

1). Top display window: In normal operation mode, it shows the remaining time
to the next event. If the remaining time is longer than 99'59”, the display will
show minutes only. When
^/MUT
key is pressed, it will show
the number of the upcoming event (e.g.,
t2
,
t3
...). When an event time is up, it
will flash the event number (
t2
,
t3
,
t4
, and etc.) until the alarm is turned off. In
programming mode, it shows the name of a parameter. In stopwatch mode (
nE
= 1,
tdIr
=
up
), it will display the duration of current event.
2). Bottom display window: In normal operation mode, it shows the remaining
time to the end of all events. If the remaining time is longer than 99’59”, the
display will show minutes only. In programming mode, it shows the set value of
the parameter. In stop watch mode, it will display the duration of accumulated
time that has elapsed.
3).
RUN
indicator: This red indicator should be solid on when the timer is
running; it flashes when the timer is paused; it should be off when the timer is
stopped.
4).
OUT
indicator: This green indicator turns on when the relay is on (pull-in);
turns off when the relay is off (drop-out). This indicator should be synchronized
with an external flashing buzzer if it was connected to the relay.
5).
SET
key: Press it momentarily to set event timers
t1
,
t2
,
t3
, and so on;
press and hold it for 1 second to enter the parameter setting mode. In
parameter setting mode, press it momentarily will go to next parameter setting.
This key is disabled when timer is running.
6).
V/ RST
key: Reset timer or decrease a parameter value. When the timer is
running or is showing “END”, press it to stop the timer and reset the timer. In
the parameter setting mode, press it will decrease the value of a parameter.
Each time you press and release this key, the value will decrease by one unit.
When you press and hold it, the value will continuously decrease; as the
holding time increases, the speed of number decreasing will accelerate.
7).
^ / MUT
key: Mute/cancel the relay, or increase a parameter value. When
the timer is running, press this key to allow the coming up event number (
t2
,
t3
,
and etc.) to be shown in the top display window. When an event timer is up and
relay is pulled in, press this key once to release the relay. This key only affects
the relay. It does not interrupt the running timer. In stopwatch mode, press it to
restart the count-up timer in the top display window as the second stopwatch.
In the parameter setting mode, press it to increase the value of a parameter.
Each time you press and release, the value will increase by one unit. When
you press and hold it, the value will continuously increase; as the holding time
increases, the speed of number increasing will accelerate.
8).
START
key: Press it to start the timer. When timer is flashing “END”, press
it once to stop the flashing, and get the timer ready for the next run. Press the
START key again will restart the timer. This key is disabled when timer is
running. In stopwatch mode, press it to start and stop the timer.
