N The control output and digital
display are held until a reset input

F In UP mode, the digital display
continues to increment up to
“9999” even after reaching the set

When the set time has elapsed,
the output signal is generated
during the one-shot time. The

However , in both UP and DOWN
modes, the digital display returns

restarts the timing operation.
When the set time has elapsed,
the output signal is generated

2. In this timing chart, the number of step advances during the one-shot time varies in accordance with the selected rated time and
duration of the one-shot time.
3. In C and P modes, set time value n should be suf ficiently longer than the one-shot time t.

Connection of Reset and Gate Inputs
For reset input, connect a contact or an open collector type transis -
tor between terminals 8 and 9. The timer resets when contact is
made
or when the transistor is ON. For gate inputs, connect a con -
tact
or an open collector type transistor between terminals 8 and 10.
The timer stops when contact is marked or when the transistor is
ON.
Use a contact of high contact reliability, or an open collector type
transistor with characteristics: VCEO = 20 V min., VCE(S) (residual
voltage)
= 3 V max., I
C
= 50 mA min. and I
CBO
(leakage current) =
0.5 µA max.. Use of a gate input contact with minimum contact
bounce
(chatter) is a must, since the contact bounce time will cause
an error in timer operating time.
When connecting a solid-state circuit not of the open collector type
to the gate or reset inputs as shown below , the voltage of the solid-
state circuit (+V) should be 13 to 30 V , and the V
CE(S)
of the transis -
tor
should be less than 3 V (the current that flows from either termi -
nal
9 or 10 is approximately 10 mA). Moreover , it is essential that the
circuit be ON for gate or reset input, and OFF when there is no input.
Connection of a Power Supply for Externally
Connected Components
The H5AN has a built-in power supply for externally connected com -
ponents
such as sensors for gate or reset input, or loads connected
to the solid-state control output (12 VDC, 80 mA).
Power can be applied to the sensors and loads simultaneously .
Load
(gate) (reset)
Simultaneous Input to a Number of H5AN Tim-
ers with the Same Contact or the Same Open
Collector Transistor
A reset or gate input may be applied to two or more units of H5AN
with only one contact or transistor as shown below . In this case, cau -
tion
is required as a large current flows into the transistor . (The cur -
rent
that flows from H5AN is approximately 10 mA pre unit.)

Note: The decimal point is not shown in the digital display .
1. Since
the H5AN T imer is capable of reading the input data at
any time during normal operation, the set time can be
changed
during power application. This feature sets back the
output from the timer by temporarily setting the longer time or
quickens the output by setting the shorter time. During normal
operation, the set time may be accidentally changed by
touching
a thumbwheel switch, causing the timer to operate
with a dif ferent set time. To prevent this possibility , keep the
front cover closed except when changing the set time.
2. When the set time is all zeroes (e.g., 000.0 s or 00 hrs 00 min),
there will be a momentary control output upon power
application
which can be used to check normal output. When
changing the set time during normal operation, pay special
attention
not to alter the set value to this state.
3. Since the sexagesimal system is adopted, when a rated time
of 99 min 59 s or 99 hrs 59 min is selected, any value set to 6
or more (i.e. 6-9) in the order of x 10 s or x 10 min respectively
will be rated as 5. Some erroneous setting examples are
shown
below .
Examples of Setting/Actual Operating T ime
4. When changing the set time while power is being supplied, an
inadequate push of the thumbwheel switches will display two
numbers in one digital display window , causing the operating
time to drift widely. Therefore, press the thumb-wheel
switches surely. Take particular care in the case when the
other
three digits are all zero, since the improper setting of the
fourth switch to create four zeroes will cause a momentary
output.

5. When operating the built-in selector switches of the
H5AN-4DM T imer with a backup power supply function for
memory protection, it is necessary to reset (either
externally or manually) the timer at the time the power is
applied.
Also when this type of timer is connected to a device (or
manually) this must also be done when power is applied for
the first time.
Note: If the timer is not reset, it operates in accordance with the
previous specifications or with the factory set specifica-
tions.

6. The type without a backup power supply function for memory
protection operates as shown below depending on the
duration
of the power failure.
(A) Power failure of 0.01 s max.
Note: The timer starts in the initial setting
upon power recovery.
(B)
Power failure of 0.5 s min.
Note: The timer starts in the initial setting
upon power recovery.
(C)
Power failure of 0.01 to 0.5 s.
Note: Either (A) or (B)
The type with a backup power supply function for memory protec-
tion restarts in the status preceding the power failure as shown in
(A),
regardless of the duration of the power failure.
7. The type with backup power supply for memory protection
incorporates a battery for backup power supply which lasts
for about ten years of normal use, meaning data is retained
even during a power failure lasting ten years. (The battery
cannot
be replaced.)
8. When using the timer in operation modes other than N and F
modes (i.e., C, R, K, P , and Q), the control output is available
for the one-shot time only. For this reason, adjust the
one-shot
time by rotating the one-shot time adjustment screw
on the front panel (variable within a range to 0.1 to 1 s).
Mounting
A Mounting Fixture is included with the H5AN. Mount the Unit using
the Mounting Fixture so that the Unit is secure and does not move
Loosen (to the left) the
screws on the Mounting
Fixture sufficiently and
attach
it from the bottom.
Tighten (to the right) the
screws on the Mounting
Fixture completely.
When the screw is tight-
ened
completely , you will
hear it turning freely in
place.
