• A single twin timer unit that repeats (variable) ON/OFF.
• Multiple ranges with a 0.1 s to 500 h time specification on a single unit.
• The output ON/OFF operation is indicated by red and green LED’s.
It’s easy to check the operation at a glance.
• The AC free power supply and shorter body make it easier to use.
• A new screw terminal type has been added to the conventional pin type. Wiring
can be done easily with a screwdriver.
• Compliant with UL, CSA, CE and LLOYD.

PM4H SERIES MODES AND TIME SETTING
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
ON
,
FL
,
FO
,
OF1
,
SF
,
OS
,
OF2
,
OC
.
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.
