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 , , , , , , , .

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.

PRECAUTIONS IN USING THE PM4H SERIES

1. Input connections (PM4H-A type)

1) Be sure not to use terminal 8 as the

common terminal of the input signal as

shown in Fig. A. Otherwise, the internal

circuit of the timer may be damaged. Use

terminal 0 as the common terminal as

shown in Fig. B.

If the circuits is connected as in Fig. C,

the internal circuits must be broken. Be

sure to connect the circuit as in Fig. D.

2) When one input signal is simultane-

ously applied to more than one timer,

be sure to avoid the wiring shown in Fig.

E. Otherwise, the short-circuit current

will flow and cause damage. Be sure to

align the polarity of the power supply as

shown in Fig. F.

3) Terminal 0-4 (screw terminal x-c)

should be connected as the start input.

Connect terminals 0-5 (screw terminal

x-v) for reset signal input. Connect

terminals 0-3 (screw terminal x-b) for

stop signal input. Be sure not to connect

with other terminals and apply excessive

voltage. The internal circuit will be dam-

aged.

4) The input wiring other than the power

supply circuit should avoid these condi-

tions, high-voltage wiring and parallel

wiring with power wire. Wire in short with

using the shielding wire or metal wiring

tube.

5) For start, reset and stop input, use

gold-plated contact with high reliability.

Since contact bouncing causes errors

in the start, use an input contact less

bounce time.

6) Keep the minimum signal input time

over 0.05 s.

2. Input signal conditions

(PM4H-A type)

1) Connection of contact input (Pin type

example

Use gold-plated contacts with high-reli-

ability. The bounce time at the contacts

causes errors in the timer operation

time. Accordingly, use start input contact

whose bounce time is short. The resist-

ance when shorted should be less than

1k7, and when open resistance should

be more than 100k7.

For the screw terminal type, connect the

terminal x to the each input signal.

2) Connection of non-contact input (Pin

type example)

(open-collector)

Apply the open-collector connection.

The characteristics of the transistor used

must be VCEO=10V or more, IC=10mA or

more, and ICBO=6μA or less. Additionally,

the input impedance must be 1k7 or

less, and the residual voltage must be

0.6V or less.

For the screw terminal type, connect the

terminal x to the each input signal.

3) Connection of non-contact input (Pin

type example)

(voltage input)

Even if the open collector is not used,

input is also possible from the non-con-

tact circuit of 6 to 30V DC. In this case,

the start input is turned on when the sig-

nal is turned from H to L.

The residual voltage must be 0.6V or

less when Q is on. On the AC type, an

insulated transformer is required as

the power supply for the photoelectric

sensor, etc. (power supply for the input

devices).

Note: Keep the minimum input signal time of

each signal to 0.05s or more.

3. Checking the contacts before use

(PM4H-F only)

When the power ON time is less than

the minimum power application time,

the contacts may remain in an ON state,

so the state of the contacts should be

checked before use. When the contacts

are in an ON state, activating them once

will return them to their normal state (the

OFF state after time-out). (Be aware that

relay characteristics may result in the

contacts being in that same ON state

if exposed to excessive vibration and

impact during transport.)

4. Time setting

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)

Note) 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.

PRECAUTIONS IN USING THE PM4H SERIES

5. Superimposed surge of power

supply (PM4H series common)

For the superimposed surge of power

supply, the standard waveform is taken

as the standard value for surge-proof

voltage.

If external surge occurs exceeding the

specified value, the internal circuit may

break down. In this case, use a surge

absorption element.

The positive and negative voltages are

applied each five times between the

power pins.

The typical surge absorption elements

include a varistor, a capacitor, and a

diode. If a surge absorption element is

used, use an oscilloscope to see whether

or not the foreign surge exceeding the

specified value appears.

6. Acquisition of CE marking

Please abide by the conditions below

when using in applications that comply

with EN61812-1.

1) Overvoltage category III, pollution

level 2

2) This timer employs a power supply

without a transformer, so the power and

input signal terminals are not insulated.

(PM4H-A only)

(1) When a sensor is connected to the

input circuit, install double insulation on

the sensor side.

(2) In the case of contact input, use dual-

insulated relays, etc.

3) The load connected to the output con-

tact should have basic insulation.

This timer is protected with basic insula-

tion and can be double-insulated to meet

EN/IEC requirements by using basic

insulation on the load.

4) Please use a power supply that is

protected by an overcurrent protection

device which complies with the EN/IEC

standard (example: 250 V 1 A fuse, etc.).

5) You must use a terminal socket or

socket for the installation. Do not touch

the terminals or other parts of the timer

when it is powered. When installing or

un-installing, make sure that no voltage

is being applied to any of the terminals.

6) Do not use this timer as a safety cir-

cuit. For example when using a timer in

a heater circuit, etc., provide a protection

circuit on the machine side.
