1. Operation method
1) Operation mode setting
[PM4H-A type]
8 operation modes are selectable with
operation mode selector.
Turn the operation mode selector with
screw driver.
Operation mode is shown up through the
window above the mode selector. The
marks are , , , , , , , .
Turn the mode selector to the mark until
you can check by clicking sound.
Confirm the mode selector position if it is
correct.
If the position is not stable, the timer
might mis-operate.
2) Time range setting
[PM4H series common]
16 time ranges are selectable between
1s to 500h.
Turn the time range selector with the
screw driver.
Clockwise turning increases the time
range, and Counter-clockwise turning
decrease the time range.
Confirm the range selector position if it is
correct.
If the position is not stable, the timer
might mis-operate.
3) Time setting [common]
To set the time, turn the set dial to a
desired time within the range.
Instantaneous output will be on when the
dial is set to “0”.
When the instantaneous output is used,
the dial should be set under “0” range.
(Instantaneous output area)
When power supply is on, the time
range, setting time and operation mode
cannot be changed.
Turn off the power supply or a reset sig-
nal is applied to set the new operation
mode.
If the position is not stable, the timer
might mis-operate.

2. How to use “Set ring” [PM4H series common]
1) Fixed time setting
Set the desired time and put 2 set rings
together.
Insert the rings into stopper to fix the
time.
2) Time range setting
Example: Time range 20s to 30s.
Shorter time value setting
Set the dial to 20s.
Place the stop ring at the right side of
stopper.
Longer time value setting
Set the dial to 30s.
Place the stop ring at the left side of
stopper.
PM4H SERIES MODES AND TIME SETTING
Note) The stoppers for the lower limit setting set ring and the upper limit setting set ring face the opposite directions.
