■ Basic Setting
■ Using the Setting Ring
Setting of Selector
Setting a Specific Time
The selectors can be turned clockwise and counterclockwise to
select the desired time unit, time range, output type (only for H3BAN8H) 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 malfunction
could result from improper setting.
Mount the Panel Cover on the Timer, set the desired time with the
time setting knob, and place Time Setting Ring A onto the time
setting knob so that the time setting notch of Time Setting Ring A is
in the center of the reset lock position of the Panel Cover.

Selection of Time Unit and Time Range
The desired time unit (sec, min, hrs, or 10h) is displayed in the
window below the time setting knob by turning the time unit selector
located at the lower right corner of the front panel. A time range (1.2,
3, 12, or 30) is selected with the time range selector at the lower left
corner of the front panel, and the selected time range appears (in the
window at the lower right part) within the plastic frame of the time
setting knob.
Example: To set the time to 10 s.
Limiting the Setting Range
Example: To set a range of 10 and 20 s.
Mount the Panel Cover on the Timer, set the time setting knob to 10 s
(the lower limit of the setting range), and place Time Setting Ring C
onto the time setting knob so that the stopper of Time Setting Ring C
is on the right edge of the reset lock position of the Panel cover. Next,
set the time setting knob to 20 s (the upper limit of the setting range),
place Time Setting Ring B onto the time setting knob so that the
stopper of Time Setting Ring B is on the left edge of the reset lock
position of the Panel Cover.

There are three types of Panel Covers (Y92P-48GL, Y92P-48GB,
and Y92P-48GM), all of which are available in three colors. Use the
most suitable type of Panel Cover with the design of the scaling plate
according to the application.
When setting a given time for the Timer, use of the Y92S-27 or
Y92S-28 Time Setting Ring facilitates the time setting operation and
minimizes possible setting errors by operators.
The Time Setting Ring and Panel Cover should be used as a pair.

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
setting knob.
Note:
1. The Y92A-48B Protective Cover is made of a hard plastic
and therefore it must be removed to change the timer set
value.

Safety Precautions
CAUTION
Minor electric shock may occasionally occur. Do not
disassemble the product or touch the interior of the Timer.
Minor burns may occasionally occur. Do not touch the
product while power is being supplied or immediately
after power is turned OFF.
Minor fires may occasionally occur. Tighten terminal
screws to a torque of 1.08 N·m so that they do not
become loose.
Minor electric shock may occasionally occur during
operation. Install the terminal cover.
■ Precautions for Correct Use
Changing the Setting
Do not change the time unit, time range, or operation mode while the
Timer is in operation, otherwise the Timer may malfunction.
Connecting the Operating Power
Supply
The H3BA-N@ contains a capacitor-drop power circuit. Use a
sinusoidal power supply with a commercial frequency. Do not use
power supplies with a high frequency component (such as inverter
power supplies) for Timers with 110 or 220-VAC specifications. Using
these power supplies can damage internal circuits.
Minor electric shock, fire, or malfunction may occasionally
occur.
Do not allow metal fragments, lead wire scraps, or chips
from processing during installation to fall inside the Timer.
If voltages other than the rated voltage is applied, the internal
components may be damaged. The internal element (varistor) will be
damaged if a voltage of higher than 100 VAC is applied to the 24VDC line.
■ Precautions for Safe Use
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value immediately or the Timer
may not be reset or a timer error could result.
Please observe the following precautions for safe use of this product.
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.
Environmental Precautions
Store the Timer within specified ratings. If the Timer has been stored
at -10°C or lower, let it stand for 3 hours or longer at room
temperature before turning ON the power supply.
If the wiring to the terminal 2 (common terminal for both the power
supply and input signals) is broken, the internal circuit will be
destroyed.
Use the Timer within the specified ratings for operating temperature
and humidity.
5, 6, 7
G, S, R
Do not operate the Timer in locations subject to sudden or extreme
changes in temperature, or locations where high humidity may result
in condensation.

Do not use the Timer in locations subject to excessive dust, corrosive
gas, or direct sunlight.
Closed
2
Do not use the Timer in locations subject to vibration or shock.
Extended use in such locations may result in damage due to stress.
Install the Timer well away from any sources of static electricity, such
as pipes transporting molding materials, powders, or liquids.
Usage Precautions
Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
Pay careful attention to polarity to prevent wrong connections when
wiring terminals.
Input/Output
An appropriate input will be applied to the input signal terminals of
the Timer when one of the input terminals (terminals 5, 6, and 7) and
the common terminal (terminal 2) for the input signals are shortcircuited. Do not attempt to connect any input terminal to any
terminal other than the common terminal or to apply voltage across
other than the specified input and common terminals or the internal
circuits of the Timer may be damaged.
Internal elements may be destroyed if a voltage outside the rated
voltage is applied.
Maintain voltage fluctuations in the power supply within the specified
range.
The Timer uses a transformerless power supply. Do not touch the
input terminals while the supply voltage is being applied, otherwise
an electric shock may occur.

Operating Time Setting
■ Mounting
When setting the operating time, do not turn the setting knob beyond
its scale range. For precise time setting, conduct operation tests by
adjusting the setting knob.
Surface Mounting
The accuracy of the operating time of the Analog Timer is indicated
by the percentage value on the basis of the full-scale time. The
absolute fluctuation value will not be improved by changing the time
setting. Therefore, when selecting the model, be sure that the
application will be able to use a time setting as close as the full-scale
time setting of the Timer.
Others
When conducting a dielectric test, impulse voltage test, or insulation
resistance test between the electric circuit and non-current-carrying
metal parts of the Timer mounted to a control panel, be sure to take
the following steps. These steps will prevent the internal circuitry of
the Timer from damage that may be caused if a machine on the
control panel has an improper dielectric strength or insulation
resistance.
1. Separate the Timer from the circuitry of the control panel by
disconnecting the socket from the Timer or wires.
2. Short-circuit all terminals of the Timer.
If any device with no-contact output, such as a proximity sensor,
photoelectric sensor, or SSR, is directly connected to the Timer,
current leakage from the device may cause Timer malfunction. Be
sure to test the device with the Timer before using the device for
actual applications.
There is no particular restriction on surface mounting directions, but
be sure that the Timer is securely mounted horizontally.
P2CF Socket
When mounting the Timer vertically with the P2CF Socket, consider
the movable hooks and be sure that there is a 20-mm space on each
of the upper and lower parts of the Socket.
Duct
Hook
P2CF-08
Panel
Before using the Timer to switch inductive loads, be sure to connect
a surge absorbing element to the Timer in order to prevent the Timer
from malfunction and damage. A diode is an example of a surge
absorbing element for DC circuits and a surge absorber is an
example of a surge absorbing element for AC circuits.
Do not leave the Timer in time-up condition for a month or longer in
places with high temperatures, otherwise the internal parts, such as
an electrolytic capacitor, of the Timer may be damaged. Use the
Timer with an appropriate relay so that the Timer will not be left in
time-up condition for a long time.
If the Timer is mounted in contact with a mounting surface, the
service life of internal parts may be shortened. Provide at least 10
mm between the Timer and the mounting surface to prolong the
service life of the Timer.
When the Timer is reset right after the Timer goes into time-up
condition, be sure to provide the Timer with an appropriate circuit
configuration considering the resetting time of the Timer so that a
sequential error will not result.
The Timer uses the constant value read method. Be careful when
changing the set value because the output of the Timer will be ON
when the set value coincides with the count value.
Be sure that the casing of the Timer is free from organic solvents,
such as paint thinner and benzene, strong acid, and alkali solvents,
which will damage the casing.
Note: It is impossible to connect more than two Timers in parallel.
