1. RUN indicator: (the red dot at the lower right corner). It turns on when timer
starts running; turns off when timer stops.
2. Time unit indicator: turns on when time units are M:S or H:M. Turns off when
time unit is M or S.
3. Time range indicator: turns on when the time base is H:M (Hours: Minutes)
or M (Minutes). Turns off when the time base is M:S (Minutes : Seconds) or S
(Seconds).
4. Timer indicators: T1 for first delay time, T2 for second delay time.
5. OUT indicator: Turns on when relay is on. Turns off when relay is off.
6. SET key. When timer is not running, press it will switch between first delay
time setting (T1) and second delay time setting (T2); press and hold it for 3
second will enter the programming mode.

7. Down key / STP key: When timer is not running, press it will lower the time
setting value. When timer is running, press it will stop the timer. In the
programming mode, press it will go to the next programming value.
8. Up key / PAU key: When timer is not running, press it will increase the time
setting value. When timer is running, press and hold it will pause the timer. The
timer will continue running after this key is released. In the programming mode,
press it will go to the previous programming value.
9. RST key: Reset key. When timer is running, press it will restart the timer. If
"RUN" parameter is set to RST, press it will start the timer after powered up.
10. LED digital display. During normal operation as a timer, the top displays the
actual time; the bottom displays the set value. In programming mode, the top
displays setting parameters; the bottom displays programming value.
4. Terminal Assignment
Figure 2. Terminal assignment of JSL-71.
Terminal functions when timer is running:
Pause(PAU), Stop(STP), Reset(RST), Common(COM).
Connecting PAU and COM: Timer stops running. Timer will resume running
when they are disconnected.
Connecting STP and COM: Timer stops running.
Connecting RST and COM: Timer stops running and reset. Timer will restart
when they are disconnected.
5. How to Set the Timer and Relay Delay Time T1/T2
When timer is not running, press “SET” key to shift between relay delay time
T1 and T2. Simply press up/ down key will increase/decrease the set value of
each delay time. (hold up/down key to speed up changing).
For how to program the relay delay time in different relay output mode, please
see the definition of Func in next section.
6. Programming
Press SET key for 3 seconds to enter programming mode. For each parameter
setting, use up/down key to select different programming values. Press SET
key to confirm and move on to next parameter. See figure 3 next page for the
procedure. For the definition of each programming value, see following section.

Definition of Programming Values
trnG: Timer range.
S: 0.01 s ~ 99.99 s;
M:S: 1 s ~ 99 m 59 s;
M: 1 m ~ 9999 m;
H:M: 1 m ~ 99 h 59 m.
tdir: Timing direction.
up: Counting up.
dn: Counting down.
OUT: Relay output mode.
OFDL (off delay): Relay will be on at the start of timer and off when time reach
the set point.
ONDL (on delay): Relay will stay off at the start of timer and on when time
reach the set.
RUN, Timer starting run mode.
PU (power up): Timer starts when powered up.
rSt (reset): Timer starts when reset button is pressed and released.
Func, Timer operating function mode
sdL (single delay): Relay turns on at the beginning of relay delay time T1/T2
(OFDL); Relay turns on at the end of relay delay time T1/T2 (ONDL). It will not
change until the timer is reset or powered off and on again.
Dint (delayed interval): Relay turns on at the end of T1 time delay then off at
the end of T2 time delay (OFDL); Relay turns off at the end of T1 time delay
then on at the end of T2 time delay (ONDL). There is no repeat.
CYCL (cycle): Repeat relay on and off in cycle. Relay turns on at the end of T1
time delay then off at the end of T2 time delay (OFDL); Relay turns off at the
end of T1 time delay then on at the end of T2 time delay (ONDL). It will repeat
this cycle until power is off.
LU.SP: Key locker for the two key pads in the middle.
This parameter determines if the two keys in the middle will be locked for timer
value setting or stop/pause function. For applications that repeat the same time
setting, user may want the lower and up key to be locked to prevent any
accidental change. For some applications, user may want the Stop and Pause
function to be deactivated to prevent stopping the timer by accident. LU.SP
represents Lower, Up, Stop and Pause function. OF means the function is
turned off and ON means the function is turned on.
LU.SP set to OF.ON means the lower and up keys are deactivated (turned off),
but Stop and Pause keys are still functional (turned on)
ON.OF means lower and up keys are functional, but Stop and Pause functions
are turned off.
OF.OF means lower and up keys, Stop and Pause functions are all locked up .
ON.ON means lower and up keys, Stop and Pause functions are all functional.
*Note: When the Stop and Pause are locked from the front keys, the Stop and
Pause function can still be executed from the back terminals.
7. Wiring Example
Please see figure 4 on the next page for the wiring example.
Figure 4. Wiring example of JSL-71.
Power (120 or 240V AC) is sent to terminal 9 and 10. The external reset (RST)
and pause (PAU) switch should be momentary type. They are needed only if
you want to control the timer remotely. Otherwise, you can use the front keys
on the timer. These switches can also be replaced with a control signal from
computer or other control devices. The alarm speaker used in this example
is also optional. It is to show how to wire the output. You can substitute it
with any output such as a coffee grinder. The output terminals (#6, 7 and 8)
are from a “C form” internal relay. It is a dry switch that does not provide the
power by itself. In this case, the alarm is powered by the 120VAC. The
external switch connected to the alarm is for disabling the sound if needed.
8. Timing Diagrams
Following diagrams show relay output ON/OFF time under different relay
output modes and operating function modes. Please note: 1) “RUN” is set to
“rSt” in following examples, powering up to start the timer is not discussed
here. 2) Timer starts counting from the moment when reset key/switch is
released or input (TTL) signal is from low to high. 3) Timer display stops

counting as soon as stop key/ switch is pressed (from high to low), but relay
output will only be triggered when stop key/switch is released (from low to
high).
