Operation

■ Programming

H5L

The H5L Weekly Timer has the following six program modes. Use
the Mode Key to change the modes. Use the Write Key, Plus Key,
Minus Key, and Cycle Key for programming in each mode.

To set the current time in the order of "day of week",
"hour" and "minute".

1. Press the Mode Key for longer than 1 s to put
the H5L in "TIM ADJ" mode.

2. Set "DAY OF WEEK" using the Plus and/or
Minus Keys. Then press the Write Key to
write the set weekday.

3. Set "hour" using the Plus and/or Minus Keys.
Then press the Write Key to write the set
hour.

4. Set "minute" using Plus and/or Minus Keys.
Then press the Write Key to write the set
minute.

To specify first circuit operation in the order of
"hour", "minute", and "output ON or OFF"

1. Press the Mode Key to put the H5L in "PROG
1" mode.

2. Set "hour" using the Plus and/or Minus Keys.
Then press the Write Key to write the set
hour.Set minute" using the Plus and/or Minus
Keys. Then press the Write Key to write the set
minute.

3. Specify "ON" or "OFF" of output using the Plus
or Minus Key and press the Write Key to write
the set output specification.

In this manner, set ON time and OFF
time as many times as necessary.

To set for each weekday whether the program for the first
circuit set in the previous step is to be executed or not.

1. Press the Mode Key to put the H5L in "PROG 1"
"DAY SET" mode.

2. Press the Plus Key to run the first circuit and
press the Minus Key for it not to run.

3. Press the Write Key to change day of week.

Repeat steps 2 and 3 for Sunday to Saturday.

1. Use the procedure First circuit operation setting given at the left to
set the ON time to 23:50 and the OFF time to 3:00.

2. Use the procedure First circuit weekday setting given at the left to
set Monday, Tuesday, Wednesday, Thursday, and Friday.

Cycle Program

In the H5L, the cycle program can be used to repeat ON and OFF of
output for a certain period in a predetermined cycle. A cycle program
consists of the following four steps:
Start time, ON time, OFF time, Stop time

Setting A Cycle Program

Set the four steps of the cycle program in the following procedure.

Setting

To specify second circuit operation in the order of "hour",
"minute", and "output ON or OFF"

1. Press the Mode Key to put the H5L in "PROG 2"
mode.

2. Proceed with the settings in the same manner as in
the first circuit operation setting above.

To set for each weekday whether the program for the
second circuit set in the previous steps is to be executed
or not.

1. Press the Mode Key to put the H5L in "PROG 2" "DAY
SET" mode.

2. Proceed with the settings in the same manner as in
the first circuit operation setting above.

Run the H5L using the set program. In RUN mode, the
current time and output status are displayed but the
operation mode is not displayed. After starting the H5L, the
colon between the hour" and minute" blinks to indicate
that time count is in execution.

even while another program is being set. The output status display
( etc.) during programming displays the setting being
programmed. Therefore, note that the output status displayed on
the LCD may not agree with the actual output status.

Set the stop time of the cycle program.

On completing settings for the four
steps, the H5L returns automatically
to 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 programs for the first and
second circuits are set in such a manner that outputs 1 and 2
have a phase difference, note that the phase difference is
changed when any of the conditions above occur as shown in the
example below. (Therefore, it is recommended that cycle
programs are used sequentially.)

Note: Refer to "Programming

Example".

3. The cycle period (from start time to stop time) does not need to
be a multiple of the cycle frequency (ON time plus OFF time). The
cycle period can be set within a range of 1 min to 24 hrs.

4. ON time as well as OFF time can be set within a range of 1 min to
23 hrs 59 min.
