1. Overview
This JSL-71 timer can count from 0.01 second to 9999 minutes.
Operating function modes include single delay, double delay, and cycle
delay. It can count-down or count-up. The timer can be activated
automatically when powering up, by front key pad, or via remote
switch. Two different time delay settings can be programmed. User can
switch the setting with a single key press. Lock function can be
activated to prevent any accidental change.

1. RUN indicator: (the red dot at the lower right corner).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.

Figure 2. Terminal assignment
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.

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.
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

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).
