■OPERATION MODES
The gate input is not included on "economy" models H5CR-L and H5CR-LS.
Output mode A: Signal ON delay 1 (Timer resets when power comes on.)
Timing begins at the leading edge of
the start signal. The control output will
be energized when the present value
equals the preset time. The output will
be sustained until a reset signal is
applied, until power is interrupted, or
for a programmable one-shot time
period.
Output mode A1: Signal ON delay 2 (Timer resets when power comes on.)
Timing begins at the leading edge of the
start signal. The control output will be
energized if the start signal is sustained
for an amount of time equal to the preset
time. The output will be sustained until
the start signal is interrupted, until a reset
signal is applied, until power is
interrupted, or for a programmable one-
shot time period.

Output mode A-2: Power ON delay 1 (Timer resets when power comes on.)
Timing begins when power is applied.
Start signals act as a gate input,
causing the present value to hold. The
control output will be energized when
the present value equals the preset
time. The output will be sustained until
a reset signal is applied, until power is
interrupted, or for a programmable
one-shot time period.
Output mode B: Repeat cycle 1 (Timer resets when power comes on.)
The OFF/ON cycle is initiated at the
leading edge of the start signal. The
control output will be OFF for the first
cycle. In subsequent cycles the output
will be ON for the programmable one-
shot time period, then OFF for the
remainder of the preset time. The cycle
will be repeated until a reset input is
applied or power is interrupted.
The OFF/ON cycle is initiated at the
leading edge of the start signal. The
output relay will be OFF for the preset
time, then ON for the preset time. The
cycle will be repeated until a reset input
is applied or power is interrupted.
Timing begins when power is applied.
Start signals act as a gate input, causing
the present value to hold. The control
output will be energized when the
present value equals the preset time.
The output will be sustained until a reset
signal is applied or for a programmable
one-shot time period. If power to the unit
is interrupted, the control output will be
de-energized. The output will re-
energize once power is restored.

Output mode E: Interval (Timer resets when power comes on.)
Timing begins on the leading edge of the
start signal. The control output is only
energized during timing. The timer is
reset when power is interrupted or a
reset signal is applied.
The OFF/ON cycle is initiated at the
leading edge of the start signal. The
output relay will be OFF for the preset
time, then ON for the preset time. The
cycle will be repeated until a reset input
is applied. If power to the unit is
interrupted, the present value will hold.
The cycle will continue from that point
once power is restored.
The OFF/ON cycle is initiated at the
leading edge of the start signal. The
control output will be OFF for the first
cycle. In subsequent cycles the output
will be ON for the programmable one-
shot time period, then OFF for the
remainder of the preset time. The cycle
will be repeated until a reset input is
applied. If power to the unit is
interrupted, the present value will hold.
The cycle will continue from that point
once power is restored.
Output mode D: Signal OFF delay (Timer resets when power comes on.)
The control output is energized at the
leading edge of the start signal. Timing
begins at the trailing edge of the start
signal. The control output is de-
energized when the present value equals
the preset time.

■KEY OPERATIONS
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.

■EXAMPLES
Changing the Set Value
Run Mode
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.
Note: Read Changing Set Values in the Precautions section
before changing the timer set value during operation.
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.
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.
(Press the DISPLAY key to switch back from set mode to
run mode.)
2. Press the MODE key to scroll successively through the items
that can be set.

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.

CPU OFF Press No

Memory Set at the
factory
■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.
•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.
■OPERATING ENVIRONMENT
■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
■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.
This product contains a lithium battery. Lithium batteries
explode if incinerated. Dispose of the digital timer as a non-
combustible item.
■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.
NOTE: ALL DIMENSIONS ARE IN MILLIMETERS. To convert millimeters into inches, divide by 25.4.
