g3pf 4 operation error detection function setting the heater bu rnout 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 operation during an error heater burnout detection function note 1. the alarm is output if the load current falls below the error detection current. 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 detec tion 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.) ssr failure detection note: when using cycle control, the detect ion time increases in inverse proportion to the output duty. heater burnout detection current range model condition alarm indicator (red) alarm output terminals 5-6 terminals 7-8 g3pf- @@@ b normal unlit off none heater burnout, ssr open-circuit lit on ssr short-circuit flashing g3pf- @@@ b-ctb g3pf- @@@ b-stb normal unlit off off heater burnout, ssr open-circuit lit on off ssr short-circuit flashing off on model item g3pf- @ 25b, g3pf- @ 25b- @@@ g3pf- @ 35b, g3pf- @ 35b- @@@ detection set- ting range 1 to 25 a (1-a increments) 1 to 35 a (1-a increments) detection toler- ance 5% ( 20% for a rated load current setting of 20% or less. see table at right for details.) detection time 1.0 s max.

g3pf 10 safety precautions refer to safety precautions for all solid state relays . 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. 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. 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. minor electrical shock may occasionally occur. always turn off the power supply before performing wiring. also, always attach the cover terminal. 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 incl ude measures such as system redundancy, measures to prevent fires from spreading, and designs to prevent malfunction. (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. 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. 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. (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. 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. 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 nm. 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. (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 nm m3: 0.4 to 0.56 nm m5: 1.57 to 2.35 nm control connector mounting torque (detachable terminal) 0.25 to 0.3 nm 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. caution precautions for safe use mounted on a vertical surface mounted on a horizontal surface vertical direction panel
g3pf 11 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. (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. 3. conditions in which a power supply frequency other than the rated frequency is selected or used. (6) failure detection 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. (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. ? malfunction withstand limit (reference value): 500 v note: this value was measured under the following conditions. noise duration: 100 ns and 1 s repetition period: 100 hz noise application time: 3 min 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. 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. (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. (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. (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.

g3pf 12 (5) g3pf and duct (or other object blocking airflow) relationship (6) ventilation outside the control panel 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.) example: for 10 g3pf ssrs with load currents of 35 a, 0.54 10 = 5.40 thus, 6 fans would be required. note 1. size of fans: 92 mm 2 , air volume: 0.7 m 3 /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 temper ature that will allow the ssr to cool by convection or other means. g3pf rated current (a) 25 a 35 a required number of fans per g3pf 0.4 0.54 vertical direction mounting surface mounting surface mounting surface g3pf airflow 30 mm max.
