Basic Setting
Setting of Selectors
The selectors can be turned clockwise and counterclockwise to se-
lect 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 malfunc-
tion could result from improper setting.

Selection of Time Unit and Time Range
•H3CR-F Twin Timers
A time range (0 to 1.2, 0 to 3, 0 to 12, or 0 to 30) is selected for ON-
and OFF-time using the time range selector at the lower left corner
of the front panel, and the selected time range appears within the
plastic frame of the time setting knob (= scale range display win-
dows).
For ON-time, the desired time unit (sec, 10 s, min, and hrs, or 10 s,
10 min, hrs, and 10 h) is indicated in the ON-time unit display win-
dow at the lower right corner of the front panel and can be changed
by turning the ON-time unit selector located below the ON-time unit
display window.
For OFF-time, the desired time unit (sec, 10 s, min, and hrs, or 10 s,
10 min, hrs, and 10 h) is indicated in the OFF-time unit display win-
dow at the upper right corner of the front panel and can be changed
by turning the OFF-time unit selector located below the OFF-time
unit display window.
•H3CR-G Star-delta Timers
A star operation time range (0 to 6, 0 to 12, 0 to 60, or 0 to 120 sec-
onds) is selected with the star operation time range selector at the
lower left corner of the front panel.
The time required for switching (0.05, 0.1, 0.25, or 0.5 second) from
the star operation to the delta operation of the H3CR-G can be se-
lected with the star-delta transfer time selector at the lower right cor-
ner of the front panel.

•H3CR-H Power OFF-delay Timers
A time range (0 to 0.6, 0 to 1.2, 0 to 6, and 0 to 12) is selected with the
time range selector at the lower left corner of the front panel. No time
unit selector is available. When ordering the H3CR-H, specify S (for
the second unit) or M (for the minute unit) for your H3CR-H.

Protective Cover
Y92A-48B
The protective cover protects the front panel, particularly the time
setting section, against dust, dirt, and water . It also prevents the set
value from being altered due to accidental contact with the time set-
ting knob.
Note: 1. The Y92A-48B Protective Cover is made of a hard plas-
tic and therefore it must be removed to change the timer
set value.
2. The Protective Cover cannot be mounted if the Panel
Cover (sold separately) is used on the T imer.

Note: The undermentioned is common for all H3CR-F/G/H models.
Changing of Setting
NOTICE: Do not change the time unit, time range, or operation
mode while the timer is in operation or malfunction could
result.
Wiring (H3CR-H)
The H3CR has a high impedance circuit. Therefore, the H3CR may
not be reset if the H3CR is influenced by inductive voltage. In order
to eliminate any influence of inductive voltage, the wires connected
to the H3CR must be as short as possible and should not be
installed alongside power lines. If the H3CR is influenced by induc-
tive voltage that is 30% or more of the rated voltage, connect a CR
filter with a capacitance of approximately 0.1 µF and a resistance of
approximately 120 Ω or a bleeder resistor between the power sup-
ply terminals. If there is any residual voltage due to current leakage,
connect a bleeder resistor between the power supply terminals.
H3CR-H H3CR-H
13
Operation (H3CR-H)
An interval of 3 s minimum is required to turn on the H3CR after the
H3CR is turned off. If the H3CR is turned on and of f repeatedly with
an interval of shorter than 3 s, the internal parts of the H3CR may
deteriorate and the H3CR may malfunction.

After the forced reset function of the H3CR is activated, an interval
of 3 s minimum is required to activate the forced reset function
again. If the forced reset function is activated repeatedly with an in-
terval of shorter than 3 s, the internal parts of the H3CR may deterio-
rate and the H3CR may malfunction.

Output

If it is required that the output be turned on repeatedly with an inter-
val of shorter than 3 s, consider use of the H3CR-A in mode D (sig-
nal OFF-delay).
Power Supplies (H3CR-H)
An AC power supply can be connected to the power input terminals
without regarding polarity. A DC power supply must be connected to
the power input terminals as designated according to the polarity of
the terminals.
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.
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 could result.
For the power supply of an input device, use an isolating transform-
er, of which the primary and secondary windings are mutually iso-
lated and the secondary winding is not grounded.

Circuit

Rectifier circuit
The H3CR-H has a large inrush current; provide sufficient power
supply capacity . If the power supply capacity is too small, there may
be delays in turning ON the output.

Note: 1. The above figures are all approximations and should be used for reference only.
2. The inrush current is given mainly for DC models for the required power supply design specifications. For the H3CR-H, the inrush
current is also given for 100/1 10/120-V AC and 200/220/240-V AC models because these models have higher inrush currents than
other series.

Input/Output (H3CR-H)
An appropriate input is applied to the input signal terminal of the Tim-
er when the input terminal for the input signal is short-circuited. Do
not attempt to connect any input terminal to any terminal other than
the input terminal or to apply voltage across other than the specified
input terminals or the internal circuits of the Timer may be damaged.
*Do not connect a relay or any other load between these two
points, otherwise the internal circuit of the T imer may be
damaged due to the high-tension voltage applied to the input
terminals.

*L
When connecting a relay or a transistor as an external signal input
device, pay attention to the following points to prevent short-circuit-
ing due to a sneak current to the transformerless power supply.
If a relay or transistor is connected to two or more T imers, 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).

Environment
When using the Timer in an area with excess electronic noise, sepa-
rate the Timer , wiring, and the equipment which generates the input
signals as far as possible from the noise sources. It is also recom-
mended to shield the input signal wiring to prevent electronic inter-
ference.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions can damage the outer casing of the T imer.
Others
If the T imer is mounted on a control board, dismount the timer from
the control board or short-circuit the circuitry of the power board be-
fore carrying out a voltage withstand test between the electric cir-
cuitry and non current-carrying metal part of the Timer, in order to
prevent the internal circuitry of the Timer from damage.
