Advantech L3P Series, Operation/Setup Manual, Page: 6 / 47

The clock mode is a 12-hour with an am/pm display element. When the clock
is being displayed and the clock is in the pm time frame, the decimal point of
number 1-seven segment will be ON. Once the user has achieved the proper
clock value, they need to exit the clock set mode by pressing and holding the
button [SET/DISPLAY] for 1 second. After the 1 second, the beeper will beep
for 1 second giving the user notification that the mode is now exited. Once
the clock is set, the display will go blank and the clock set LED will turn OFF.
If the clock has been set and the user presses the button [SET/DISPLAY] for
less than 1 second, the display will show the current time for a 5 second
period and revert back to what was previously on the display.
3. Setting Interval Timer - In modes 1 – 3, the device functions as a simple
countdown timer. When you set the value, press the button
[START/RESUME]. When the value reaches 0, the relay is turned OFF and the
beeper beeps 6 sets of 2 (250ms) beeps.
Repeat Feature- the timer will remember the last time set. If you desire to
change the setting from the original setting, press start switch to recall
previous setting then input new setting.
To enter one of the 3 countdown modes, press and hold the button [MODE]
for 1 second. Holding down this button the mode will switch every 2 seconds.
Each time the mode switches, the appropriate LED of mode LEDs will be
turned ON and the value displayed will change to the modes default value.
An audible ¼ beep will also be heard.
Mode 1 0 – 99 second: DEFAULT DISPLAY = 01
Mode 2 0 – 99 minute: DEFAULT DISPLAY = 00.00
Mode 3 0 – 99 hour: DEFAULT DISPLAY = 00.00
Once the countdown value has been set, you can now start the timer by
pressing the button [START/RESUME]. The relay is turned ON. While the
timer is counting down the user can stop the event by pressing the button
[STOP]. The current countdown value will remain on the display. If you want
to resume the session you just need to press the start button again. Counting
will proceed from the point where stopped. During this operation, the run LED
is blinked at once a second.
Once the timer has counted down to 0 and stopped, you can execute the
same session (time value) by pressing the [START/RESUME] button again.
This will recall the timer value and display it. At this point, you have two
options. The first being the ability to change the value by using the
[INCREASE] or [DECREASE] buttons and the second being the ability to use
the same value and starting the event again by pressing the
[START/RESUME] button.
