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
