1. Time unit indicator: by default, the screen turns on when time format is
MM:SS (Minutes: Seconds) or HH:MM (Hours: Minutes) and flashes when the
timer is running; The screen turns off when time unit is M (Minutes) or S
(Seconds).
2. Timer indicator for seconds: turns on when the time format is MM:SS or S;
turns off when the time format is HH:MM or M.
3. Timer indicator for minutes: turns on when the time base is HH:MM or M;
turns off when the time base is MM:SS or S.
4. RUN indicator: turns on when timer is running; blinks when timer is paused;
turns off when timer is stopped.
5. OUT indicator: turns on when relay is on; turns off when relay is off.
6. SET key: press it momentarily to set T1 and T2; press and hold it for 3
second will enter the programming mode. In programming mode, press it
momentarily will go to next parameter setting. This key is disabled when timer
is running.

7. Down key / STP key: This key reduces the value in the programming mode;
when the timer is running, press it to stop the timer. (For a special stop function
in single delayed on mode, please see note 1 on page 2 for details).
8. Up key / PAU key: This key increases the value in the programming mode;
when timer is running, pressing & holding this key will pause the timer. Once
you release the Up key/ PAU key, the timer will resume.
9. RST key: reset key. When the timer is running, the reset button will reset the
timer. If "RUN" parameter is set to RST, pressing the button will start the timer
after it has powered up.
10. LED digital display: during normal operation as a timer, the top displays the
actual time; the bottom displays the preset value; in programming mode, the
top displays the parameter, and the bottom displays the parameter value.
4. Terminal Assignment
Figure 2. Terminal assignment of JSL-74A.
Details:
1. Power for the timer needs to be connected to terminal 9 and 10. The voltage
should be in the 90 to 260VAC range, like 110V AC or 240V AC.
2. Terminal 6, 7, and 8 are for relay output. Terminal 6 is normally-closed (NC)
contact. Terminal 8 is normally-open (NO) contact. Terminal 7 is common
contact of the terminal 6 and 8. When the relay is energized (or when the OUT
LED is on), terminal 8 connects to terminal 7, and terminal 7 disconnects
terminal 6; When the relay is NOT energized (or when the OUT LED is off),
terminal 6 connects to terminal 7, and terminal 7 disconnects terminal 8. The
relay is a "dry switch" that does not provide power by itself. Please see the
wiring examples in Section 7.
3. Terminal 5 is the reset terminal that has the same function as the RST key in
the front panel. Please see a note at the end this section.
4. Terminal 4 is the pause/mute terminal that function the same as the "^/PAU"
key in the front panel.
5. Terminal 3 is the stop terminal that function the same as the "V/STP" key in
the front panel.
6. Terminal 1 is the common contact for the terminal 3/4/5. There are two ways
to operate terminal 3, 4 and 5.
6.a) Connecting a normally open (NO) momentary push button switch between
the terminal (3, 4 or 5) to the COM (1). 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.
