1Safety Precautions
!WARNING Never attempt to disassemble any Units while power is being supplied. Doing so may result in serious electrical shock or electrocution.
!WARNING Never touch the I/O terminals, computer connector, Expansion Unit connector, or Battery Unit connector while power is being supplied. Doing so may result in serious electrical shock or electrocution.
!WARNING Provide safety measures in external circuits (i.e., not in the ZEN), including the following items, to ensure safety in the system if an abnormality occurs due to malfunction of the ZEN or another external factor affecting the ZEN operation. Not doing so may result in serious accidents.
•Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
•The ZEN will turn OFF all outputs when its self-diagnosis function detects any error. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.
•The ZEN outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
•Provide double safety mechanisms to handle incorrect signals that can be generated by broken signal lines or momentary power interruptions.
!WARNING Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks. Doing any of these may result in leakage, rupture, heat generation, or ignition of the battery. Dispose of any battery that has been dropped on the floor or otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they are used.
!Caution Tighten the AC power supply terminal block screws to the torque specified in the manual. Loose screws can result in fire or faulty operation.

•The output relays or the output transistors may remain ON due to faults in internal circuits such as output relays or output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
•Always turn ON power to the ZEN before turning ON power to the I/O circuits. If the ZEN power supply is turned ON after the I/ O power supply, temporary errors may result in operation.
•The life of the output relays is largely affected by the switching conditions. Confirm the operation of the system under actual operating conditions and set the switching frequency to ensure that adequate performance will be provided. Insulation faults and burning in the ZEN may result if relays are used after their performance has deteriorated.
2-2 Installation
•Install the ZEN according to instructions in the operation manual. Improper installation may cause faulty operation.
•Do not install the ZEN in locations subject to excessive noise. Malfunction may occur.
•Do not allow the ZEN to fall during installation.
•Be sure that all the mounting screws on the ZEN and Expansion I/O Unit are tightened to the torque specified in the manual. Incorrect tightening torque may result in malfunction.
•Use with the cover of the computer connector mounted. Using without the cover may result in malfunction due to dust or other foreign matter.
•Be sure that the DIN rail mounting levers, Expansion I/O Units, Memory Cassettes, Battery Units, cable connectors, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
2-3 Wiring and Connections
•Use the wires specified in this manual when wiring. Use straight crimp terminals when connecting loose wires.

•Provide circuit breakers and other safety measures to provide protection against shorts in external wiring.
•Use separate wiring ducts for signal wires from those used for power supply and high-voltage lines.
•Always check polarity when connecting cables.
•Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if foreign matter enters the Unit.
•Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
•Tighten the terminal block screws to the torque specified in the manual.
•Wire the ZEN according to instructions in the operation manual. Improper installation may cause faulty operation.
2-4 I/O Connections and Startup Precautions
•Use the Units only with the power supplies and voltages specified in the operation manual. Other power supplies and voltages may damage the Units.
•Take measures to stabilize the power supply to conform to the rated supply if it is not stable.
•Do not apply voltages exceeding the rated input voltage to input circuits. The input circuits may be destroyed.
•Do not apply voltages exceeding the maximum switching capacity to output circuits. The output circuits may be destroyed.
•Double-check all wiring before turning ON the power supply. Incorrect wiring may result in burning.
•Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected operation.
2-5 Handling
•Use, store, and transport the ZEN under the limits given for general specifications in this manual.
•Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
•Always turn OFF the power supply to the ZEN before attempting any of the following.
•Assembling the ZEN.

•Attaching or removing the Memory Cassette.
•Attaching or removing the Battery Unit.
•Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.
•Changing the operating mode.
•Using the button switches.
•Changing bit status or parameter settings.
•Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up.
•Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.
•Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.
•Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks. Doing any of these may result in leakage, rupture, heat generation, or ignition of the battery. Dispose of any battery that has been dropped on the floor or otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they are used.
•Abide by all local ordinances and regulations when disposing of the ZEN.
2-6 Maintenance
•When replacing parts, be sure to confirm that the rating of a new part is correct.
•When replacing a Unit, transfer to the new Unit and confirm all settings for clock data, internal holding bits, holding timers, and counter before starting operation again.

4Conformance to EC Directives
4-1 Applicable Directives
•EMC Directives
•Low Voltage Directive
4-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration,
xvi
|
Conformance to EC Directives |
4 |
wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61000-6-2
EMI (Electromagnetic Interference): EN50081-2
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards for the ZEN (EN61131-2).
4-3 Conformance to EC Directives
The ZEN complies with EC Directives. To ensure that the machine or device in which the ZEN is used complies with EC Directives, the ZEN must be installed as follows:
1,2,3… 1. The ZEN must be installed within a control panel.
2.You must use reinforced insulation or double insulation for the DC power supplies used for the communications power supply and I/ O power supplies.
3.ZEN models complying with EC Directives also conform to the Common Emission Standard (EN50081-2). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions.
You must therefore confirm that the overall machine or equipment complies with EC Directives.
4-4 Relay Output Noise Reduction Methods
The ZEN conforms to the Common Emission Standards (EN50081-2) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the ZEN.
Countermeasures taken to satisfy the standards vary depending on the devices on the load side, wiring, configuration of machines, etc. Following are examples of countermeasures for reducing the generated noise.

6Memory Backup
The ladder program and settings are stored in EEPROM and thus will not be lost even if the power supply is turned OFF for an extended period of time (e.g., 2 days at 25°C). The status of the following data, however, is backed up by an internal capacitor, and may be lost if power is turned OFF for an extended period of time: ON/OFF status of holding bits (H), holding timers (#), and counters (C) and the prevent value areas. For models equipped with a clock/calendar, the time and date may be reset. Always reconfirm system operation before restarting operation after the power has been turned OFF for an extended period of time. We recommend that a Battery Unit be (optional) connected in any system in which power may be interrupted for an extended period of time.

7-2 CPU Units Covered in this Manual
The material in this manual is based on the memory areas of the V1 CPU Units. If you are using a pre-V1 CPU Unit, the sizes of some of the memory areas will be different. Refer to page xxii for details.
Also, the I/O circuits and I/O terminal arrangements for CPU Units for DC power supply different between V1 and pre-V1 CPU Units, as described in the following table. Refer to page 38 for details

|
V1 CPU Units |
With CPU Units for DC power supply, the common is |
|
separated from the power supply circuit in the I/O cir- |

Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of the product. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
-
Page 15
Precautions WARNING Serious human hazard may occasionally occur due to ignition or rupture of the lithium battery used in the Battery Unit. Do not short the battery terminals or charge, disassemble, deform under pressure, or incinerate the battery. Never use any battery that has been dropped on the floor or otherwise subjected to excessive shock. -
Page 16: Precautions For Safe Use
ZEN control circuits to ensure safety of the overall system in the event of ZEN failure or external factors. If the ZEN discovers an error during self-diagnosis, operation will be stopped and all outputs will be turned OFF.
-
Page 17
Refer to Cycle Time Calculation Method on page 130 and confirm that the increase in the cycle time will not affect operation. If the cycle time is too long, it may become impossible to read input signals accurately. The increase in the cycle time will be particularly noticeable when set values are written in RUN mode for a CPU Unit with communications (ZEN-10C4@R-@-V2). -
Page 18
Store the ZEN at an ambient temperature of −40 to 75°C for LED-type CPU Units and −20 to 75°C for all other types of CPU Units. If the ZEN has been stored at −10°C or lower, allow it to stand at room temperature for 3 hours or longer before turning ON the power supply. -
Page 19: Precautions For Correct Use
• Locations subject to corrosive gas • Locations subject to direct sunlight Do not install the ZEN in locations subject to shock or vibration. Extended use in such location may cause damage from stress. In environments subject to static electricity (e.g., close to pipes conveying forming materials, powders, or fluid materials), separate the ZEN as far as possible from the source of static electricity.
-
Page 20
Precautions Do not remove the label from the left side of the CPU Unit if a Battery Unit is not mounted. Other The execution of the ladder program in the ZEN is different from that for other PLCs. Refer to Appendix B Ladder Program Execution when writing the ladder program. -
Page 21: Conformance To Ec Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards. The ZEN complies with IEC/EN61131-2 clause 8.
-
Page 22
The ZEN conforms to EN 61131-2 of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the ZEN. -
