About this Manual: This manual has been prepared to provide the information necessary to install, set up, and maintain your C-series K-type Programmable Controller, a low-cost, compact, versatile industrial control sys- tem providing up to 148 I/O points. For information regarding system programming and operation, refer to the operation manual.
Nomenclature Section 1–1 1–1 Nomenclature This section gives the names and functions of the various components of K–Type PCs and the basic Units with which they can be combined in a System. 1–1–1 CPUs In the diagram below, the C20K is shown as a representative model. Refer to Appendix A Standard Models for your model’s exact specifications.
Nomenclature Section 1–1 ROM Socket and DIP Beneath the cover are the DIP switch and the socket where an EP–ROM Switch chip may be installed. For details, see 2–7–1 Setting the CPU Dipswitch and 2–7–2 EP–ROM Installation. Only DIP switch pins 1 and 2 are on when the CPU is delivered.

Nomenclature Section 1–1 Indicators The following diagram shows the functions of the various indicators, taking the C20P as an example. OUTPUT 5 CH OUTPUT: Shows whether the output is ON or OFF. POWER: Stays lit while power is turned ON to the POWER I/O Unit.
Nomenclature Section 1–1 Vertical Mounting (All Units except the C16P and C4K can be positioned vertically.) C20P–CN411 Set to Right in Left out I/O Unit 1–1–3 Analog Timer Unit Internal variable resistors These variable resistors are used to set the timers Min.
Nomenclature Section 1–1 External Variable Resistor The contactor employs solderless terminals and must be wired as shown be- low, using AWG 28 to 22 lead wires. Analog Timer Unit connector External variable Ω resistor (20 k 1–1–4 I/O Link Units The I/O Link Unit must be used as a Remote I/O Slave, and must be used with a Remote I/O Master.
System Configuration Section 1–2 1–2 System Configuration Depending on your control requirements, you can combine various Units for a total number of I/O points ranging anywhere from 20 to 148. For example, a single C20K CPU, with no Expansion I/O Units connected, has a total of 20 I/O points, broken down into 12 input points and 8 output points.

Installation Environment Section 2–2 2–1 General This section explains how to install and set up your Control System, with spe- cifics on the proper environment, actual mounting, applicable cable, wiring, and switch settings. 2–2 Installation Environment Although the K–Type Programmable Controller is quite durable, the following conditions must be observed in order for your System to operate at its high- est level of reliability.

Installation Environment Section 2–2 Duct Work When CPUs and Expansion I/O Units are mounted horizontally, be sure that no ducts or wiring passes between them. The diagram shows an example of unacceptable mounting. If the controlled system requires either 10 A at 400 V max. or 20 A at 220 V max.
Dimensions and Installation Section 2–3 2–3 Dimensions and Installation This section gives dimensions and other information necessary for mounting the CPUs, Expansion I/O Units, Analog Timer Units, and I/O Link Units.

Dimensions and Installation Section 2–3 Another factor to consider is the I/O wiring (see 2–5 I/O Wiring). If the CPU and/or Expansion I/O Units are mounted vertically, a minimum of 70 mm open space is required for ease of I/O wiring. The spacing of the mounting holes, for both vertical and horizontal mounting is as shown below.

I/O Connecting Cable Section 2–4 Connecting I/O Link Units One I/O Link Unit can be connected directly to a CPU or to any combination of a CPU and Expansion I/O Units. It cannot be used in the same PC System with an Analog Timer Unit.
Wiring CPUs and Expansion I/O Units Section 2–5 2–5 Wiring CPUs and Expansion I/O Units Power Supply Use a commercially available 24–VDC, 100– to 120VAC, or 200– to 240–VAC power supply (depending on your model) for the CPU. When an Expansion I/O Unit(s) or an I/O Link Unit is used, the power supply must also be connected to each of these Units.

Wiring CPUs and Expansion I/O Units Section 2–5 tance must be less than 100 Ω. Do not use a ground–wire longer than 20 m. Care must be taken because ground resistance is affected by the nature of the ground, water content, season, and the amount of time that has elapsed since the wire was laid underground.
I/O Wiring Section 2–6 2–6 I/O Wiring This section shows I/O wiring diagrams for representative models of all the CPUs, Expansion I/O Units, and I/O Link Units covered in this manual. It also gives connection examples for the sensors and switches which can be con- nected as input devices.

Special Wiring Precautions Section 2–7 2–7 Special Wiring Precautions Emergency Stop Circuit An external relay circuit can be constructed to prevent a CPU breakdown or malfunction from damaging the entire System. In the following diagram, SR bit 1813 is always closed when the CPU is operating. If the program is set up as shown in the diagram, then output 0100 will be ON whenever the CPU is in either RUN or MONITOR mode, and it will function as an output to monitor whether the CPU is operating properly or not.
Page 47
Special Wiring Precautions Section 2–7 Interlock Circuit There are sometimes cases in which a PC can direct a machine to do either of two contrasting actions, and in which damage could result from a malfunc- tion in the PC. For example, the PC could be set up to output commands to a motor to operate alternately in forward and reverse.
Settings Section 2–8 The PC ignores all momentary power failures if the interruption lasts no longer than 10 ms. If the interruption is between 10 ms and 25 ms, it may or may not be detected. If the supply voltage drops below 85% for longer than 25 ms, the PC will stop operating and the external outputs will be automati- cally turned off.
Settings Section 2–8 2–8–2 EPROM Installation 1, 2, 3... 1. Remove the cover as shown above. 2. Raise the lever to unlock the socket. Holding the chip so as not to touch the pins, insert it into the socket with the notch to the left.
Settings Section 2–8 2–8–4 Inhibiting the ALARM Indicator To inhibit the ALARM indicator when using EP–ROM, set DIP switch pin 5 to ON as shown below. Connect a backup battery to preserve data memory, current counter value, and HR area bits, in case of a power failure. In order to maintain the battery, DIP switch pin 5 should normally be set to OFF.
Page 51
Settings Section 2–8 Use the 6 DIP switch pins to set the word number from 0 to 30. As shown in the diagram below, the word numbers are set in binary, with pin 5 being ”1” and pin 1 being ”16.” Beginning with pin 1, turn ON the pins required to arrive at the desired number of words.

Settings Section 2–8 When setting the I/O Link Unit, in this example, it is necessary to take into account not only the I/O words of the C500 Remote I/O Master Unit, but also those of the C20 CPU and the C40K CPU. C500 Word Assignment C20 Word Assignment C40P Word Assignment...

SECTION 3 Maintenance and Inspection 3–1 General ..............3–2 Self–Diagnostic Functions .
Self–Diagnostic Functions Section 3–2 3–1 General This section explains the proper maintenance and inspection procedures for the K–Type PCs, including specifics on replacing parts and taking precaution- ary measures to ensure reliable, trouble–free operation. 3–2 Self–Diagnostic Functions The K–Type PC has self–diagnostic functions to identify many types of ab- normal system conditions.
Replace the cover, positioning it over the Unit and snapping it into place by applying pressure to the area marked ”OMRON.” The above procedure applies to CPUs and Expansion I/O Units. The proce- dure is similar for I/O Link Units except that the cover is secured by 4 catches instead of 4 screws.

Preventive Measures Section 3–4 Precautions for Inrush When connecting the resistor or triac output to a device (such as an incan- Current descent lamp) which allows a high inrush current to flow, care must be taken to ensure the safety of the transistor or triac. The transistors and triacs are able to withstand an inrush current of ten times the rated current.
Inspection Section 3–5 Output Loads Be sure to take appropriate measures when any electrical device likely to produce noise is connected to the CPU as a load. For example, electromag- netic relays and valves generating noise of more than 1,200 V require noise suppression.
