Besure to read this manual before attempting to use the Unit and keep this manualclose at hand for reference during operation.! WARNING It is extremely important that a PC and all PC Units be used for the specifiedpurpose and under the specified conditions, especially in applications that candirectly or indirectly affect human life. You must consult with your OMRONrepresentative before applying a PC System to the above-mentionedapplications.3Safety Precautions! WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing somay result in electric shock.! WARNING Do not touch any of the terminals or terminal blocks while the power is beingsupplied. Doing so may result in electric shock.! WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do somay result in malfunction, fire, or electric shock.! WARNING Provide safety measures in external circuits (i.e., not in the ProgrammableController), including the following items, in order to ensure safety in the systemif an abnormality occurs due to malfunction of the PC or another external factoraffecting the PC operation.
Not doing so may result in serious accidents.• Emergency stop circuits, interlock circuits, limit circuits, and similar safetymeasures must be provided in external control circuits.• The PC will turn OFF all outputs when its self-diagnosis function detects anyerror or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.xii5Application Precautions• The PC outputs may remain ON or OFF due to deposition or burning of theoutput relays or destruction of the output transistors. As a countermeasure forsuch problems, external safety measures must be provided to ensure safety inthe system.• When the 24-VDC output (service power supply to the PC) is overloaded orshort-circuited, the voltage may drop and result in the outputs being turnedOFF. As a countermeasure for such problems, external safety measures mustbe provided to ensure safety in the system.! WARNING When transferring programs to other nodes, or when making changes to I/Omemory, confirm the safety of the destination node before transfer.
Not doing somay result in injury.4! CautionExecute online edit only after confirming that no adverse effects will be causedby extending the cycle time. Otherwise, the input signals may not be readable.! CautionTighten the screws on the terminal block of the AC Power Supply Unit to thetorque specified in the operation manual. The loose screws may result in burningor malfunction.Operating Environment Precautions! CautionDo not operate the control system in the following places:• Locations subject to direct sunlight.• Locations subject to temperatures or humidity outside the range specified inthe specifications.• Locations subject to condensation as the result of severe changes in temperature.• Locations subject to corrosive or flammable gases.• Locations subject to dust (especially iron dust) or salts.• Locations subject to exposure to water, oil, or chemicals.• Locations subject to shock or vibration.! CautionTake appropriate and sufficient countermeasures when installing systems in thefollowing locations:• Locations subject to static electricity or other forms of noise.• Locations subject to strong electromagnetic fields.• Locations subject to possible exposure to radioactivity.• Locations close to power supplies.! Caution5The operating environment of the PC System can have a large effect on the longevity and reliability of the system.
Improper operating environments can lead tomalfunction, failure, and other unforeseeable problems with the PC System. Besure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.Application PrecautionsObserve the following precautions when using the PC System.! WARNING Always heed these precautions. Failure to abide by the following precautionscould lead to serious or possibly fatal injury.• Always connect to a ground such that the grounding resistance does not exceed 100 Ω when installing the Units. Not connecting to the correct groundmay result in electric shock.xiiiApplication Precautions5• Always turn OFF the power supply to the PC before attempting any of the following.
Not turning OFF the power supply may result in malfunction or electricshock.• Mounting or dismounting I/O Units, CPU Units, Memory Cassettes, or anyother Units.• Assembling the Units.• Setting DIP switches or rotary switches.• Connecting or wiring the cables.• Connecting or disconnecting the connectors.! CautionFailure to abide by the following precautions could lead to faulty operation of thePC or the system, or could damage the PC or PC Units. Always heed these precautions.• Fail-safe measures must be taken by the customer to ensure safety in theevent of incorrect, missing, or abnormal signals caused by broken signal lines,momentary power interruptions, or other causes.• Construct a control circuit so that power supply for the I/O circuits does notcome ON before power supply for the Unit.
If power supply for the I/O circuitscomes ON before power supply for the Unit, normal operation may be temporarily interrupted.• If the operating mode is changed from RUN or MONITOR mode to PROGRAMmode, with the IOM Hold Bit ON, the output will hold the most recent status. Insuch a case, ensure that the external load does not exceed specifications. (Ifoperation is stopped because of an operation error (including FALS instructions), the values in the internal memory of the CPU Unit will be saved, but theoutputs will all turn OFF.)• Always use the power supply voltage specified in the operation manuals. Anincorrect voltage may result in malfunction or burning.• Take appropriate measures to ensure that the specified power with the ratedvoltage and frequency is supplied. Be particularly careful in places where thepower supply is unstable.
An incorrect power supply may result in malfunction.• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting mayresult in burning.• Do not apply voltages to the input terminals in excess of the rated input voltage.Excess voltages may result in burning.• Do not apply voltages or connect loads to the output terminals in excess of themaximum switching capacity. Excess voltage or loads may result in burning.• Disconnect the functional ground terminal when performing withstand voltagetests.
Not disconnecting the functional ground terminal may result in burning.• Install the Unit properly as specified in the operation manual. Improper installation of the Unit may result in malfunction.• Be sure that all the mounting screws, terminal screws, and cable connectorscrews are tightened to the torque specified in the relevant manuals. Incorrecttightening torque may result in malfunction.• Be sure to leave the labels attached at the time of shipment on the CPM1 orCPM2A when wiring in order to prevent wiring cuttings from entering the Unit.• Remove the label after the completion of wiring to ensure proper heat dissipation.
