■ PROGRAMMING SEQUENCE

The H5L weekly timer has six program modes. Use the mode key
to change the modes. Use the write key, plus and minus keys and
cycle key for programming in each mode.

Mode sequence Programming details

Cycle program

The cycle program in H5L can be used to repeat ON and OFF
output patterns for a length of time. A cycle program consists of
four steps: Start time, ON time, OFF time and Stop time.

Setting Cycle Program

Set the cycle program with the following four steps:

Setting
start time

Set the "hour" and "minute"

of start time using the +
and - keys.

↓

Setting Set the ON time of the cycle
ON time frequency in the order of

"hour" and "minute".

↓

Setting Set the OFF time of the cycle
OFF time frequency in the order of

"hour" and "minute".

NOTE: The H5L operates according to the program already set,

even while another program is being set. The output
status display shows the program being set. The actual
output status may not agree with the displayed status
during programming.

↓

Setting Set the stop time of the
stop time cycle program.

↓

Normal After the four steps are set,
program H5L automatically returns to
mode normal program mode.

Cautions on Using Cycle Programs

1. When the current time is included within the set cycle period,
the cycle operation starts (output turns ON) on completing
the cycle program setting (when stop time is written).

2. When any of the following occurs during a cycle period, the
cycle operation restarts from output ON:

Recovery after power failure
Current time adjustment
Change of start or stop time of the cycle program

during operation
For this reason, if the cycle program is set in such a manner
that outputs 1 and 2 have a phase difference, as shown
below, the phase difference is changed automatically
when any of the abovementioned conditions occur. We
recommend using cycle programs sequentially.

3. The cycle period (from start time to stop time) must not be a
multiple of the cycle frequency (ON time plus OFF time). The
cycle period can be set between 1 minute and 24 hours.

4. ON time as well as OFF time can be set within a range of
1 minute to 23 hours 59 minutes.

6

H5L

■ DELETING ON/OFF PROGRAM STEPS

Use the MODE and WRITE keys to advance to the output status
indicator of the steps to be deleted. Use the + and
– keys to make the output status indicator invalid (no bar).
Press the WRITE key and the step is deleted.

■ DELETING CYCLE PROGRAM STEPS

Use the MODE and WRITE keys to advance to the first step of
the cycle program. Push the CYCLE key followed by the WRITE
key. All four stpes of the cycle program are deleted.

H5L

■ CLEARING THE PROGRAM

The H5L cannot be cleared by cycling the power OFF/ON since a
built-in battery protects the memory. In order to clear the contents
of the memory, follow these steps.

1. Loosen the screw above the cycle key on the left side of timer
front, then slide the front panel up.

2. Turn the timer over and depress the metal strip at the top near
the area of the small hole.

3. The contents of the memory are cleared and the display will
show all of the graphics for approximately 5 seconds. This
may be used for a quick visual check.

CAUTION: Use the front panel override switches to control the

Programming Example

■ CREATE A TIMING CHART BEFORE PROGRAMMING

Always create a timing chart before
programming the timer. The hardcopy
provides an excellent tool if trou­bleshooting is needed. If changes to
the programming are necessary, having
the hardcopy will make the job easier.

The timer will generate outputs during
programming depending on the logic of
the current or previous program. Use
the output override switches to
manually control the outputs if this is
undesirable.

■ SETTING ON AND OFF PROGRAMS, CYCLE PROGRAMS

In this example, the first circuit is programmed to turn ON at 7:40 and OFF at
19:30. This circuit is operated from Monday through Friday and stopped on
Saturday and Sunday.
The second circuit is cyclically operated with each parameter set as follows:

Start time: 6:50
ON time: 5 minutes
OFF time: 20 minutes
Stop time: 20:30

The second circuit is stopped from operating on Sunday and operated from
Monday through Saturday. The current time is assumed to be 11:15 a.m. on
Tuesday.

Writing the Program

Setting the current time

H5L

First circuit

Second circuit

To set the current time, "day of the week", "hour", and "minute" must be specified.
First, turn on the power to the H5L. Press the Mode key for more than 1 sec. The
TIM ADJ indicator is displayed.
Set 11:15 on Tuesday, the current time in example1.

Start with setting the day of the week. The blinking indicator indicates the parameter
that can be set. Set the current day of the week to Tuesday by pressing the + or –
key.

When "TUE" is displayed, press the Write key to store the current day of the week in
memory. Then the "hour" indicator will flash at this time and the "day of the week"
indicator will stop blinking.

Set the current hour to 11 by pressing the + or – key, followed by the Write key.

At this time, the "minute" indicator will blink. Set the current minute to 15 by pressing
the + key or – key, followed by the Write key.

This completes the current time setting.

Next, program the first circuit's operation.

8

H5L

First Circuit Operation Setting

To program the operation of the first circuit, "hour", "minute", and "output" must be
specified.

Press the MODE key to set the H5L in PROG 1 mode. The display will be as shown
on the left.

Since the first circuit is turned ON at 7:40, set the "hour" to 7 by pressing the + or –
key and then store it in memory by using the Write key.

Then "minute" will start blinking. Set it to 40 by using the + or – key and store it in
memory by pressing the Write key.

Now, the output status indicator will blink. Set the output to the ON status with the +
key followed by the Write key.
(If the + key is pressed twice at this time, the display will give an invalid indication
( ). Then if the Write key is pressed, this program will be deleted.)

H5L

The display returns to the initial status as shown on the left and waits for the next
program step to be input.

Since the first circuit should be turned OFF at 19:30, set the hour to 19 and the minute
to 30 by using the + or – key and then the Write key.

Now the output status indicator starts blinking. Set the output to OFF status by the –
key and store it in memory by the Write key.

The display returns to the initial status and waits for the next program step to be input.
As the first circuit operation setting is completed, let us turn to setting the "day of the
week".

9

H5L

Second Circuit Operation Setting

Press the MODE key to set the H5L in PROG 2 mode. The display appears as shown
on the left.

In example 1, as the second circuit is to be cyclically operated, specify the cycle
program by pressing the Cycle key.

START

Set the start time (6:50) first. Set the hour to 6 and the minute to 50 by pressing the +
or – key. Write each set value with the Write key.

START

Then, set the ON time, which is 0:05 in this example.

H5L

STOP

Write the hour of 0 by pressing the Write key.
Set the minute to 5 and store it in memory by using the Write key.

Next, set the OFF time.
The OFF time is to be 0:20.

Finally, by pressing the Write key, set the hour to 0. In addition, set the minute to 20
by pressing the + or – key. Write it by pressing the Write key.

Next, set the time at which the cyclic circuit operation is to be stopped. The stop time
is to be 20:30.

Set the hour to 20 by pressing the + or – key followed by the Write key. Set the
minute to 30 by the + or – key followed by the Write key.

10

STOP

Now, the programming of the cyclic operation is completed.
The display is as shown on the left and waits for the next program to be input. Since
the second circuit operation in example 1 has been completed, let's move to setting
the day of the week.

H5L

Second Circuit Day-of-the-Week Setting

Press the MODE key to set the H5L in the DAY SET mode of the PROG 2 mode.
The display will be as shown on the left.
As the initial condition, the second circuit is to be operated on all the days of the
week, which means all the indications by the day indicators are reverse video except
that of the SUN indicator which blinks.

In example 1, the second circuit is not operated on Sunday but on all the other days;
set Sunday to be stopped accordingly using the – key and the Write key.
Then, the MON indicator starts blinking. Since on Monday through Saturday the
operation is set to be activated as the initial condition, there is no more need to set the
operation.

Running the Program

Now all the parameters have been programmed as in example 1. Press the MODE
key to set the H5L in the RUN mode.
The display will be as shown on the left.
The output status indicators show the current status of both outputs.

H5L

■ PROGRAMMING ERRORS

1. When the OFF time is set at the same hour and minute as the ON
time, "hour" indicator blinks twice the normal rate for showing a
program error. In this case, set the OFF (or ON) time again.

2. When the ON/OFF program is superimposed on the cyclic period
(from cycle start to cycle stop), the program error is indicated as
shown below. Set the "hour" and "minute" outside the cyclic
period.

3. When a cycle program is superimposed on the existing program
(ON time, OFF time, or cycle program), the program error is
indicated as shown below. Change the start time or stop time of
the cycle program not to overlap the other existing program.
