The following table shows the timer settings when it is shipped. Change the settings as necessary to suit the system before
operation. Settings and the display receive power from the internal battery and are, therefore, unaffected by external power
interruptions. With the initial settings, there will be no output even if the power supply is connected. External inputs and outputs
cannot be used without a power supply.

Reset Resets present value (to zero in UP mode, to preset in DOWN mode).

Gate Inhibits timer operation.

Outputs Control output (OUT) Outputs made according to designated output mode when corresponding preset is reached.

Control inputs are not accepted while reset input is ON.
Reset indicator lit while reset input is ON.

Key protected indicator lit while key protect input is ON.

■ EXAMPLES
Run Mode

Changing the Set Value

To change the set value from 3 hr 5 min to 4 hr 5 min, press
the 3 key so that the number 4 appears in the hour's place.

• Pressing keys 1 through 4 increments the corresponding
column by 1.

• The columns can be changed in any order, but the output will
be turned ON if the set value is less than the present value.

• Nonsignificant zeros are suppressed on the set value display.

Setting Mode

Changing Settings in the Set Mode

1. Press the MODE key to switch from run mode to set mode.

• The timer will continue operation according to existing
settings when switched from run mode to set mode during
operation.

• The MODE key will be locked if the key protection function
is enabled.

• Settings changed in the set mode do not take effect until
run mode is entered. Because the operating conditions will
change once this occurs, always use the RESET key or a
reset input to reset operation.

2. Press the MODE key to scroll successively through the items
that can be set.

Note: Read

3. To change the selected item,

• Press the MODE key until the desired item appears.

• Change the item setting by pressing keys 1 through 4.

run mode.)

Precautions

H5CR H5CR

Precautions

■ POWER SUPPLIES

•The input circuit is not isolated from the power supply circuit.
The internal circuit might be damaged by a surrounding AC
circuit, so use an isolated AC power supply with equipment
connected to the input circuit.

•If power is interrupted for less than 10 ms, operation will
continue normally. If power is interrupted for 10 to 500 ms,
operation will be inconsistent, and timing may stop or reset,
depending on the mode.

•Connect the power supply voltage through a relay or switch
in such a way that the voltage reaches a fixed value
immediately.

•Depending on switching frequency, current surges may
degrade relay contacts; relays with a capacity greater than
10 A are recommended.

■ INPUT AND OUTPUT

•Do not use external sources to increase the voltage of input
signals (control signal, reset, gate, and key protection).

•Be sure that the load of the control output (contact, transistor)
is less than the maximum values indicated in the
specifications. If the output load exceeds the recommended
value, the life span of the contact output type will be
shortened dramatically, and the transistor of the transistor
output type will be damaged.

•The transistor output is opto-isolated from the internal
circuitry, so either NPN or PNP transistors can be used.

■ SELF-DIAGNOSTIC FUNCTION

•The following displays will appear if an error occurs. The
present value and output enter the same status as after
pressing the RESET key.

■ CHANGING SET VALUES

•The timer set value can be changed while the timer is
operating, so a high value can be set temporarily to
inactivate the timer, or a low value can be set to activate the
timer more quickly. If the set value is changed accidentally
during operation, the timed output might be activated.
Therefore, turn the key protection input ON unless the set
value is being changed.

•To avoid changing the output when changing the set value, it
is recommended to begin changing the set value by entering
a large number in the higher digit.

■ OPERATING ENVIRONMENT

•When using the timer in an area with much electrical noise,
separate the timer, wiring, and the equipment which
generates the input signals as far as possible from the noise
sources. It is also recommended to shield the input signal
wiring to prevent electrical interference.

•Organic solvents (such as paint thinner), as well as very
acidic or basic solutions, might damage the outer casing of
the timer.

■ OTHER

•When the timer is installed in a control box and tests are
conducted which may damage the timer's internal circuitry
(for example, a test measuring the maximum voltage
difference between the control circuit and metal
components), remove the timer from the control box or short
circuit the terminals.

CAUTION

This product contains a lithium battery. Lithium batteries
explode if incinerated. Dispose of the digital timer as a non­combustible item.
