Note B. Pin 10 is the common pin for the pin 6/7/8. There are two ways to
operate terminal 6, 7, and 8.
a) Connecting a normally open (NO) momentary push button switch between
the pin (6, 7 or 8) to the COM (10). Please note, the function starts when you
release (or open) the button of the switch, not when you press down the switch.
See Figure 5.
b) Connecting a DC logic signal (TTL or CMOS or voltage in the range from 3
to 30 VDC) between the terminal (6, 7 or 8) to the COM (10). 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 10Kohm resistor to the gate for signal input. See Figure 6.
The function of all these terminals is accomplished by the rising phase of
control signal. If the control signal is from a momentary NO switch that is
connected to the terminal, the action starts when switch is released (from close
to open). When the control signal is from another digital device, the action
starts when voltage goes from low to high.
Note C. Pin 9 is a special terminal reserved for Espresso Shot Timer function
(when FUNC is set to EST) in the JSL-64A and JSL-64A-EST. When it is
connected with the COM pin, the timer resets its display and start counting up
from zero. When it is disconnected from COM pin, the counting stops.
5. Getting Started
5.1 Powering up the timer
To power up the timer, simply connect 120 VAC or 220 VAC power to pin 1
and 2. It is recommended to use a power supply or power cord that has an
ON/OFF switch on it.
5.2 General operations
A brief description of the keys on the timer are described below. Please also
refer to Section 6 for details of parameter RUN, STOP, and PAUS. The

Details about each parameter
Note 1.T1 is the set value in Single Delay (SDL) mode. It is also the first set
value in in Delayed Interval Mode (DINT) and the Cycled Mode (CYCL) mode.
Note 2. T2 is the second set value in Delayed Interval Mode (DINT) or in the
Cycled Mode (CYCL). This parameter will only be displayed if the Timer Mode
FUNC is set to either DINT or CYCL mode.
Note 3: FUNC is the timer operating mode, it can be set to SDL, DINT, CYCL,
or EST.
SDL (Single Delay):The timer counts a single period of time that is
defined in T1. The relay can either be turned on during this period of timer or it
can be turned on at the end of this period of time, depends on the OUT setting.
When OUT = OFDL, the relay turns on at the beginning when timer starts
counting, and turns off when the counting stops. When OUT = ONDL, the relay
stays off when timer starts counting, and the relay turns on when the timer
reaches the set value till the RST (reset) key is pressed or when the power to
the device is cycled. Please refer to Note 6 for details about OUT parameter.
In Single Delay and On-Delay mode (i.e., FUNC = SDL, OUT = ONDL), a
special parameter “STOP”will appear in the parameter menu. For details
please refer to the Note 8 below.
DINT (Delayed Interval): The timer will count time for two periods of time,
T1 and T2, and then stops. Relay action depends on the OUT setting. When
OUT =OFDL, the relay turns on at the end of T1, stays on during T2 time, and
then turns off at the end of T2 time. When OUT = ONDL, the relay turns on at
the beginning at T1 time, turns off at the end of T1 time, stays off during T2,
and then turns on again at the end of T2 time. This is a single action process.
CYCL (Cycle): The timer will repeat a counting cycle that consists of two
periods of time, T1 and T2. The relay turns on/off during each cycle depending
on the OUT setting. When OUT = OFDL, the relay turns on at the end of T1,
stays on during T2 time, and then turns off at the end of T2 time. When OUT =
ONDL, the relay turns on at the beginning at T1 time, turns off at the end of T1
time, stays off during T2, and then turns on again at the end of T2 time. This
cycle will be immediately repeated till it is stopped or reset.
EST (Espresso Shot Timer): This is a special mode designed for counting
the shot time (brew time) on an espresso machine. The timer display resets to
zero and it starts counting up when the pin 9 and 10 are shorted together. The
timer stops counting when terminal 9 and 10 are disconnected. The time unit is
determined by the parameter T1U. Pressing the RST key can clear the display.
The relay output, STP key, and PAU key are not functional in this mode. The
settings of parameter T2U, TDIR, OUT, RUN, STOP, and PAUS are irrelevant
to this mode.
Note 4. T1U and T2Udefine the time unit for T1 and T2. (Note, T2 is only
available when FUNC = DINT or CYCL).

ONDL (on-delay): the relay will stay OFF when the timer starts counting
and the relay will turn ON when the timer reaches the set value.
Note 7.RUN determines how does the timer start counting.
PU (power up): the timer starts counting when the device is powered up.
RST (reset): the timer starts when reset button is pressed and released.

Note 8. The parameter STOP defines the relay output status when STP key is
pressed during timer T1 is counting.
(** The parameter STOP parameter will only appear in the menu when FUNC =
SDL and OUT = ONDL.)
When running the single-delay (FUNC = SDL) and on-delay mode (OUT =
ONDL), depending on the applications, user may want the output relay
(normally open) to stay at off position (which is the initial status), or, stay at on
position (which is the relay’s final status) when the STP key is pressed. Here
are two examples. A) Some users use the timer to turn on a buzzer at the end
of a process for notification purpose. They want to be able to disable the
buzzer (change to the initial status) by simply pressing down the stop button
once he acknowledged the notification. B) Some users want to delay the
process of turning on a load. But sometimes, they may want to cancel the
delay (change to the final state) to start the oven by pushing the stop key.
In order to satisfy these two conflict requirements, a special parameter for stop
function, STOP will show up in the parameter menu when both ONDL (on
delay) and SDL (single delay) are selected, STOP can be selected as 0
(default) or 1. When it is set to 0, during the delay, stop signal will set relay to
the final state (pulled-in). When it is set to 1, during the delay, stop signal will
set the relay to the initial state (dropped-out). When the time delay is finished
and relay pulled in, user can reset the relay to the initial state by sending a stop
signal, regardless of the STOP setting.
Note 9. The parameter PAUS defines whether the relay output (pin 4 and 5)
should be changed from ON to OFF while the timer is running and the PAU key
is pressed. When PAUS = 0, pressing the PAU key will only pause the timer
and it will NOT affect the relay output status. When PAUS = 1, pressing the
PAU key will not only pause the timer but also change a relay output status
from ON to OFF. However, it will not affect relay status if the relay is OFF.
7. Wiring Examples
1) Signal controlled by switches
Power (120 or 240V AC) is sent to pin 1 and 2. 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 (#4 and 5)
are from an 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.

3) Espresso shot timer
In this example, we will use a small relay (120V coil voltage and a pair of
normally open NO contacts) with JSL-64A timer. The espresso machine use
120VAC power and it has a vibration pump that runs at 120VAC. To use this
timer as an espresso shot timer, please set FUNC = EST, and T1U = S. Then
press RST key to clear the screen. The display will show “0.00”as shown in
the Figure 8 below. Wiring of the timer, relay, and the pump is shown in the
Figure 9 below.

Whenever the pump is activated, the mini relay R30A’s coil will be energized to
pull its NO contacts in, so the pin 9 and 10 of the timer are shorted together,
the timer will start counting time up in seconds. The timer stops counting when
the pump is deactivated.
8. Timing Diagrams
The following diagrams show how the relay output status is affected by RST,
PAU, and STP key/terminals under different FUNC (Timer Function) and OUT
(Relay Output Mode) settings.
Please note that: 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 signal (TTL) is rising from
low to high. 3) Timer display stops counting as soon as stop key/switch is
pressed (voltage from high to low), but relay output will only be triggered when
stop key/switch is released (voltage from low to high).
