Operation
■ Error Detection Function
● Setting the Heater Burnout Detection Level
• The heater burnout detection level is set with switches on the front of the G3PF.
• Turn the switches to the current value to be detected.
The top switch sets the tens digit, and the bottom switch sets the ones digit.
The default settings are followings: Setting switch (top row): 0
Setting switch (bottom row): 1
∗Example of setting 12 A
Setting switch (top row): 1
Setting switch (bottom row): 2

2. Take the detection tolerance into consideration in setting the error
detection current. (For details, refer to the Heater Burnout Detection
Current Range table at the right.)
3. When using cycle control, heater burnout detection is possible at a
control cycle of 200 ms min. and an output duty of 50% min. (When
combined with the G32A-EA, heater burnout can be detected at an
output duty of 50% or higher.)
4. When using cycle control, the detection time increases in inverse
proportion to the output duty.
5. When used in combination with optimal cycle control (G3ZA), the
heater burnout detection function cannot be used.
6. Do not set the heater burnout detection current to 0 A. Doing so would
cause constant detection of a SSR short-circuit failure when no
operation input is applied. Also, settings 4 to 9 on the top setting switch
are invalid. Do not set the switch to these values.
7. The heater burnout detection function cannot be disabled. If it is not
needed, set it to the lowest setting (1 A).
8. When the heater burnout detection level is changed, the new value
becomes effective immediately after the change. (The set value can be
changed in the G3PF even during operation.)

G3PF
Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
CAUTION
The G3PF may rupture if short-circuit current
flows. As protection against accidents due to
short-circuiting, be sure to install protective
devices, such as fuses and no-fuse breakers, on
the power supply side.
3. Conditions in which the G3PF may be subject to
condensation as the result of rapid changes in
temperature.
4. Conditions in which the G3PF may be dropped or subject
to excessive vibration or shock.
5. Conditions in which the G3PF is not packaged.
Minor burns may occasionally occur. Do not
touch the SSR or the heat sink while the power is
being supplied or immediately after the power
supply has been turned OFF. The SSR and heat
sink become extremely hot.
(3) Mounting
1. Do not use the G3PF if the heat radiation fins have been
bent by being dropped. Doing so may result in malfunction
due to a reduction in the heat radiation performance.
2. Do not block the movement of the air surrounding the
SSR or heat sink.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the
SSR immediately after the power supply has been
turned OFF.
Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Abnormal heating of the SSR may result in shorting
failures of the output elements or burn damage.
3. Make sure that there is no excess ambient temperature
rise due to the heat generation of the G3PF. If the G3PF
is mounted inside a panel, install a fan so that the interior
of the panel is fully ventilated. Otherwise, shorting failures
of the output elements or burn damage may result.
4. Make sure the DIN track is securely mounted. Otherwise,
the G3PF may fall.
5. Do not handle the G3PF with oily or dusty (especially iron
dust) hands. Doing so may result in malfunction.
6. Mount the G3PF in the specified direction (on a vertical or
horizontal surface). Otherwise excessive heat generated
by the G3PF may cause short-circuit failures of the output
elements or burn damage.
Minor electrical shock may occasionally occur.
Always turn OFF the power supply before
performing wiring. Also, always attach the cover
terminal.
Precautions for Safe Use
OMRON constantly strives to improve quality and reliability.
SSRs, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible
to ensure safety if the SSRs are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using
an SSR, always design the system to ensure safety and prevent
human accidents, fires, and social harm in the event of SSR
failure. System design must include measures such as system
redundancy, measures to prevent fires from spreading, and
designs to prevent malfunction.

7. When mounting the G3PF to a control panel or other
fixture with screws, be sure to tighten the screws to a
torque of 0.98 to 1.47 N·m. A lower level of tightening
torque may cause the G3PF to fall.
8. Do not drop the G3PF or subject it to excessive vibration
or shock. Doing so may result in damage, malfunction, or
deterioration of performance characteristics.
(1) Operating and Storage Environments
Do not use or store the G3PF in the following locations. Doing
so may result in damage, malfunction, or deterioration of
performance characteristics.
1. Locations subject to corrosive or flammable gases.
2. Do not store in locations subject to ambient storage
temperatures outside the range −30 to 70°C.
3. Do not use in locations subject to ambient operating
temperatures outside the range −20 to 60°C.
4. Do not use in locations subject to relative humidity outside
the range 25% to 85%.
5. Locations subject to high temperature or high humidity.
6. Locations subject to condensation as the result of rapid
changes in temperature.
7. Locations subject to exposure to water, oil, or chemicals.
8. Locations subject to dust (especially iron dust) or salts.
9. Locations subject to rainwater or water splashes.
10.Locations subject to direct sunlight.
(4) Wiring
1. Use wires that are thick enough for the load current.
Otherwise, excessive heat generated by the wire may
cause burning.
Tightening torque M2: 0.22 to 0.28 N·m
M3: 0.4 to 0.56 N·m
M5: 1.57 to 2.35 N·m
Control connector mounting torque (detachable
terminal)
0.25 to 0.3 N·m
2. When tightening terminal screws, prevent any non-
conducting material from becoming caught between the
screws and the tightening surface. Otherwise, excessive
heat generated by the terminal may cause burning.
3. Use wires that are suited to the load current and voltage.
Otherwise, excessive heat generated by the wires may
cause burning, or the outer covering of the wire may melt,
resulting in electrical shock or ground fault.
4. Use a crimp terminal size that is suited to the diameter of
the wire. Otherwise, it may result in burning, or the outer
covering of the wire may melt, resulting in electrical shock
or ground fault.
11.Locations subject to shock or vibration.
(2) Transport
Do not transport the G3PF under the following conditions.
Doing so may result in damage, malfunction, or deterioration
of performance characteristics.
1. Conditions in which the G3PF may be subject to water or
oil splashes.
2. Conditions in which the G3PF may be subject to high
temperature or high humidity.

G3PF
5. Do not use wires with a damaged outer covering.
Otherwise, it may result in electric shock or ground
leakage.
6. Do not wire any wiring in the same duct or conduit as
power or high-tension lines. Otherwise, inductive noise
may damage the G3PF or cause it to malfunction.
Precautions for Correct Use
The SSR in operation may cause an unexpected accident.
Therefore it is necessary to test the SSR under the variety of
conditions that are possible. As for the characteristics of the
SSR, it is necessary to consider differences in characteristics
between individual SSRs.
(5) Adjustment and Use
Do not adjust or use the G3PF under the following conditions.
Doing so may result in damage, malfunction, or burning.
1. Conditions in which voltage or current exceeding the rated
values is applied to the input or output terminals.
2. Conditions in which a load exceeding the rated range is
selected or used.
The ratings in this catalog are tested values in a temperature
range between 15°C and 30°C, a relative humidity range
between 25% and 85%, and an atmospheric pressure range
between 88 and 106 kPa. It will be necessary to provide the
above conditions as well as the load conditions if the user wants
to confirm the ratings of specific SSRs.
3. Conditions in which a power supply frequency other than
the rated frequency is selected or used.
(6) Failure Detection
(1) Solvents
Do not allow the resin parts of the G3PF to come in contact
with solvents, such as alcohol, thinner, trichloroethane, or
gasoline. Doing so will dissolve markings and may result in
deteriorating the performance of the parts.
If the G3PF control circuit or alarm output circuit should
malfunction, the failure detection function and output will not
operate normally. To protect against this possibility, it is
recommended that the design includes redundant safety
functions.
(2) Oil
Do not allow the terminal cover of the G3PF to come in contact
with oil. Doing so may cause the cover to become cloudy or to
crack.
(7) Noise and Surge Effects
If noise or an electrical surge occurs that exceeds the
malfunction withstand limit for the G3PF output circuit, the
output will turn ON for a maximum of one half cycle to absorb
the noise or surge. Confirm that turning the output ON for a
half cycle will not cause a problem for the device or system in
which the G3PF is being used prior to actual use. The G3PF
malfunction withstand limit is shown below.
(3) Mounting
Do not drop the G3PF or subject it to excessive vibration.
Doing so may result in damage, malfunction, or deterioration
of performance characteristics.
(4) Mounting Interval (Panel Mounting)
Note: When close mounting, check Load Current vs. Ambient Temperature
under Engineering Data.

Note 1. If the air inlet or air outlet has a filter, clean the filter regularly to prevent
it from clogging to ensure an efficient flow of air.
2. Do not locate any objects around the air inlet or air outlet, otherwise the
objects may obstruct the proper ventilation of the control panel.
3. A heat exchanger, if used, should be located in front of the G3PF to
ensure the efficiency of the heat exchanger.
(7) G3PF Ambient Temperature
The rated current of the G3PF is measured at an ambient
temperature of 40°C.
(8) The G3PF uses a semiconductor to switch the load. This
causes the temperature inside the control panel to increase
due to heating resulting from the flow of electrical current
through the load. G3PF reliability can be increased by adding
a ventilation fan to the control panel to dispel this heat, thus
lowering the ambient temperature of the G3PF.
(Arrhenius's law suggests that life expectancy is doubled by
each 10°C reduction in ambient temperature.)

Thus, 6 fans would be required.
Note 1. Size of fans: 92 mm2, Air volume: 0.7 m3/min, Ambient temperature
of control panel: 30°C
2. If there are other instruments that generate heat in the control panel
in addition to SSRs, more ventilation will be required.
3. Ambient temperature: The temperature that will allow the SSR to
cool by convection or other means.
