JAPPLICATION EXAMPLES

A Mode: ON-delay

ON-delay operation (A mode) is a basic mode.

1. Power-ON Start/Power-OFF Reset

The power-ON start/Power-OFF reset operation is a standard

operating method. The start terminals are connected. Timing

starts when power is applied. The output is energized when the

accumulated time equals the set time. The output relay or

transistor remains energized until power is disconnected or a

reset input is applied. The minimum resetting time is 0.1 second.

2. Signal Start/Signal Reset

The signal start/Signal reset operation is useful for remote control

of the Timer. Power is applied continuously. Timing starts at the

leading edge of the start input. The output relay is energized

when the accumulated time equals the set time. Subsequent start

signals that occur during or after timing will not be accepted. The

output relay or transistor will remain energized until a reset input

is applied or power is interrupted. The minimum signal input is

0.05 second.

3. Cumulative Timing Using the Gate Input with ON-Delay

With a gate signal, the Power-ON start operation and Signal start

operation can be controlled (the operation can be interrupted).

When the gate signal is closed, timing is temporarily stopped.

When the gate signal opens, timing resumes at the point of

interruption. The gate input terminal permits the timer to sum up

times t1and t2as shown in the timing chart.

B/B2 Mode: Repeat Cycle

The repeat cycle operation in the B and B2 modes can be

effectively applied to lamp or buzzer (ON and OFF) alarms or the

monitoring of an intermittent operation with a display.

1. Power-ON Start/Power-OFF Reset

The start terminals are connected. Timing starts when power is

applied. The output relay or transistor operates according to

mode B (OFF/ON/OFF pattern) or mode B2 (ON/OFF/ON

pattern), whichever is set. The cycle repeats until a reset input is

applied or power is disconnected.

2. Signal Start/Signal Reset

If there is an abnormal signal, flashing starts. When the abnormal

condition is restored, a reset signal stops the display flashing.

Power is continuously applied. The ON/OFF cycle is initiated at

the leading edge of the start input.

In Mode B the output relay or transistor will be OFF for the set

time and then ON for the set time, creating an operation pattern

of OFF/ON/OFF.

In Mode B2 the output relay or transistor will turn ON for the set

time and then OFF for the set time, creating an operation pattern

of ON/OFF/ON. This cycle will be repeated until a reset input is

applied or power is disconnected. The minimum signal input time

is 0.05 second.

C Mode: Signal ON/OFF-delay

The Signal ON-/OFF-delay operation (C mode) is useful for the

control of distribution of products on a production line into boxes

by the specified number or time.

1. Power-ON Start/Instantaneous Operation/Time-limit Reset

The timing cycle starts when power is applied. When the timer

reaches set point, the output status changes and holds that

status until power turns OFF to reset the timer. Minimum reset

Installation

JCHANGING THE SETTING

Do not change the time unit, time range, or operation mode while

the Timer is in operation, or the Timer may malfunction.

The time unit and time range can be set with the respective

selectors turned clockwise or counterclockwise.

The selectors are notched so that they will snap when they are

properly set. Do not set the selectors midway between notches,

or the Timer may break or malfunction.

JPOWER SUPPLIES

Pay the utmost attention not to make mistakes in polarity when

wiring the Timer.

The H3CR Series uses a transformerless power supply. Do not

touch the input terminals while the supply voltage is applied, or

an electric shock may be received.

A DC power supply can be connected if its ripple factor is 20% or

less and the mean voltage is within the rated operating voltage

range of the Timer.

Be aware that the operating voltage will rise by 5% if the rated

voltage is applied to the Timer continuously while the ambient

temperature is close to the maximum permissible ambient

temperature.

For the power supply of an input device of the H3CR-A/-AS, use

an isolating transformer with the primary and secondary windings

mutually isolated and the secondary winding not grounded.

Rectifier circuit

The power supply terminal 2 of H3CR-A/-AS is a common

will be damaged.

G, S, R

An AC power supply can be connected to the power input

terminals without regard to polarity. A DC power supply must be

connected to the power input terminals as designated according

to the polarity of the terminals.

Make sure that the voltage is applied within the specified range,

or the internal elements of the Timer may be damaged.

Connect the power supply voltage through a relay or switch in

such a way that the voltage reaches a fixed value at once, or the

Timer may not be reset, or a timer error may result.

JINPUT/OUTPUT

Relationship between Input and Power Supply

Circuits (H3CR-A/-AS)

The H3CR-A/-AS uses transformerless power supply. When

connecting a relay or transistor as an external signal input

device, pay attention to the following points to prevent

short-circuiting due to a sneak current to the transformerless

power supply. If a relay or transistor is connected to two or more

Timers, the input terminals of those Timers must be wired

properly so that they will not differ in phase, or the terminals will

be short-circuited to one another.

not attempt to connect the input terminal to any terminal other

than the common terminal or to apply voltage across terminals

other than the specified input and common terminals, or the

Note: 1. Power supply terminal 2 is a common terminal for input

signals to the Timer. Never use terminal 10 as the com-

mon terminal for this purpose, or the internal circuit of

the Timer will be damaged.

2. Do not connect a relay or any other load between

these terminals, or the internal circuit of the Timer will

be damaged due to the high-tension voltage applied to

the input terminals.

Since the input circuit and the power supply circuit are configured

independently, the input circuit can be turned ON or OFF

irrespective of the ON/OFF state of the power supply.

It must be noted that a voltage equivalent to the power supply

voltage is applied to the input circuit.

When connecting a relay as an external signal input device, pay

attention to the following points to prevent short-circuiting due to

a sneak current to the transformerless power supply.

H3CR-A H3CR-A

If a relay or transistor is connected to two or more Timers, the

input terminals of those Timers must be wired properly so that

they will not be different in phase or the terminals will be

short-circuited to one another (refer to the figures below).

The input wires must be as short as possible. If the floating

capacity of wires exceeds 1,200 pF (approx. 10 m for cables with

120 pF/m), the operation will be affected. Pay particular attention

when using shielded cables.

The H3CR-AjS transistor output is isolated from the internal

circuitry by a photocoupler. Therefore, either NPN or PNP output

is possible.

The power supply circuit of the H3CR-A Series (except for

H3CR-AjS) is a switching circuit. If the power line connected to

the power supply circuit has a transformer with high inductance,

a counter-electromotive voltage will be induced. To suppress the

voltage, apply a CR filter to the power supply line.

Do not set the dial to minimum in repeat cycle mode (B, B2) or

the contacts may be damaged.

JBASIC SETTING

Setting of Selector

The selectors can be turned clockwise and counterclockwise to

select the desired time unit, time range, or operating mode.

Each selector has a snap mechanism that secures the selector at

a given position. Set the selector at a position at which it is

secured. Do not set it midway between two securing positions or

a malfunction could result from improper setting.

JTIME SETTING RINGS

Time setting rings allow the operator to lock in a selected, preset

time. They must be used with Y92P Panel Covers. Each ring fits

snugly around the time setting knob. A notch on the ring engages

the tab on the panel cover to prevent setting knob travel. Omron

offers two types of time setting rings in medium gray. The

Y92S-27 setting ring is used for a single set point. The Y92S-28

pair of rings are used to lock in two set points for a timing range.

Y92S-27 Setting a Single Preset

In this example, the time setting will be locked at 10 minutes:

Select timing function and set unit of measure to “min”. Install the

panel cover. Turn the time setting knob to 10. Align the notch on

the ring with the tab then press the ring onto the time setting

knob.

screws. To release the adapter, lift the tab at the rear of the

adapter.

Several timers may be panel mounted close

together using Y92F-30 adapter as shown

here. When mounting two or more timers in a

vertical line, arrange the adapters so that their

molded tabs are positioned on the right and

left sides. When mounting two or more timers

in a horizontal line, arrange the adapters so

that their molded tabs are positioned on the

top and bottom sides.

JTRACK MOUNTING

Using P2CF-j

jSocket

The P2CF-jj socket has two hooks that

secure the timer to the socket. Be sure to

allow at least 20 mm (0.79 in) clearance

above and below the socket to gain access

and to release the hooks for servicing and

maintenance. Insert timer into the socket.

Latch hooks. Then clip rear of the socket to

the track. Push the bottom onto the track until

the latch hooks securely.

Removal

Pull the latch on the socket with a flat-blade

screwdriver and remove the timer and socket

as one unit.

Precautions

JOPERATING ENVIRONMENT

Do not use the Timer in the following locations.

DLocations with radical temperature changes.

DLocations with high humidity that may result in

condensation.

DLocations with excessive vibration or shock.

DLocations with corrosive gas or dust.

DLocations where the Timer is exposed to sprayed water, oil,

or chemicals.

Organic solvents (such as paint thinner) as well as strong acid or

alkali solutions will damage the outer casing of the Timer.

If the Timer is used in an area with excessive electrical noise, be

sure to separate the Timer, wires, and input device as far as

possible from the noise sources. Shield the input signal wiring to

prevent electrical interference.

JVOLTAGE WITHSTAND TEST

If the Timer is mounted to a control board, remove the Timer from

the control board or short-circuit the control board circuitry before

carrying out a voltage withstand test between the electric circuitry

and non-charged metal part of the Timer. This protects the

internal circuitry of the Timer from damage.

JPRECAUTIONS FOR EN (VDE)

CONFORMANCE

The H3CR-A Series, installed as a built-in timer, conforms to

EN61812-1 (VDE0435/P2021) provided that the following

conditions are satisfied.

Make sure that no voltage is applied to any terminals before

removing the Timer from the Socket.

The output section of the H3CR-A is provided only with basic

isolation. Provide supplementary basic isolation on the load side

connected to the output so that reinforced isolation required by

the EN (VDE) standards will be ensured.

The H3CR-A itself is designed under the following conditions:

DOvervoltage category III

DPollution degree 2

DIsolation

Operation parts: Reinforced isolation

With clearance of 5.5 mm and creepage distance of 5.5 mm

at 230 VAC

Output: Basic isolation (See Note.)

With clearance of 3 mm and creepage distance of 3 mm at

230 VAC

Note: The 11-pin model ensures basic isolation by itself and also

ensures basic isolation with the 11-pin model mounted to

the OMRON P2CF-11 or P3GA-11 Socket.

Connect the two output contacts different in polarity to the loads

so that they will be the same in potential.
