Instruction Manual

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

JSL-73B Multi-Event Timer for Beer Brewing

Version 2.1 (May, 2017)

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.
