Safety Precautions (H3CR-H)
Note: The undermentioned is common for all H3CR-H models.
■ Power Supplies
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.
With the H3CR-H@RL, for the power supply of an input device, use
an isolating transformer, of which the primary and secondary
windings are mutually isolated and the secondary winding is not
grounded.
■ Input/Output (H3CR-H@RL)
An appropriate input is applied to the input signal terminal of the
Timer 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.
The H3CR-H@RL 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 input is made simultaneously from one input contact or a transistor
to the H3CR-H and a Timer whose common input terminals are used
as power terminals, such as the H3CR-A, a short-circuit current will
be generated. Either input through isolated contacts, or isolate the
power supply for one of the Timers.

■ Wiring
The H3CR-H has a high impedance circuit. Therefore, the H3CR-H
may not be reset if the H3CR-H is influenced by inductive voltage. In
order to eliminate any influence of inductive voltage, the wires
connected to the H3CR-H must be as short as possible and should
not be installed alongside power lines. If the H3CR-H is influenced by
inductive 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
supply terminals. If there is any residual voltage due to current
leakage, connect a bleeder resistor between the power supply
terminals.
■ Operation
An interval of 3 s minimum is required to turn on the H3CR-H after
the H3CR-H is turned off. If the H3CR-H is turned on and off
repeatedly with an interval of shorter than 3 s, abnormal heating or
burning may occur in internal elements.
After the forced reset function of the H3CR-H 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 interval of
shorter than 3 s, the internal parts of the H3CR-H may deteriorate
and the H3CR-H may malfunction.
If it is required that the output be turned on repeatedly with an
interval of shorter than 3 s, consider use of the H3CR-A in mode D
(signal OFF-delay).
■ Others
If the H3CR-H is dropped or experiences some other kind of shock,
because a latching relay is used for output, contacts may be reversed
or go into a neutral state. If the H3CR-H is dropped, reconfirm correct
operation.
