Expansion I/O Units are only 35 mm wide. Support Software with Simulation Function • Programs can be easily written, saved, and monitored by personal computer. • Programs can be simulated on the personal computer without connecting to the ZEN. Note: CPU Units with 10 I/O points can be expanded to 34 I/O points. Expansion I/O Units cannot be connected to Economy-type CPU Units. Note: For notebook computers that do not have an RS-232C serial port, connect the computer to the ZEN by connecting an OMRON CS1W-CIF31 USB-Serial Conversion Cable to the ZEN-CIF01 Connecting Cable. Other Versatile Functions • Use of a Memory Cassette makes it easy to copy and save programs. • Equipped with two analog input channels (CPU Units with DC power supply only). • Password function ensures security. (See note.) • Multi-language display in six languages (English, Japanese, German, French, Spanish, Italian). (See note.) • Display user-set messages or analog-converted values. (See note.) Note: Not supported for ZEN-@C2@@-@-V2 models. ■ Enhanced Features of V2 CPU Units Improved Weekly Timer and Calendar Timer Functions RS-485 Communications Model Added to Series Note: Not supported for ZEN-@C2@@-@-V2 models. • The time precision has been increased. Conventional model: 2-min difference/month ↓ -V2 models: ±15-s difference/month (at 25°C) • Multiple-day operation and pulse-output operation are now possible. • These improved functions are convenient for time-controlled applications such as lighting and air conditioning control. Production line conditions can be remotely monitored by monitoring the ZEN control status. Production line Office More Precise Analog Input Lighting control Air conditioning control Economy-type Added to the Series • Economy-type CPU Units with a more affordable price have been added to the series, although Expansion I/O Units cannot be added. Conventional model: ± 10% FS → -V2 models: ± 1.5% FS DC power supply models are equipped with two analog inputs (0 to 10 V). There are four analog comparators. The increased precision makes it even easier to use the Unit in simple control applications with voltage, current, temperature, and other analog values. 8-digit Counter, 150-Hz Counter • An 8-digit counter and 8-digit comparator have been added. • The maximum count for DC power supply models is 150 Hz. 12 to 24 VDC Line Voltage Operation Twin-timer Operation Added Operation is now possible with 12 VDC. Twin-timer operation allows you to set ON and OFF times separately, greatly simplifying intermittent operation. Expansion I/O Units have been reduced to half-size (35 mm wide). 2 ZEN V2 Units ■ Series Configuration CPU Units Power supply voltage: 100 to 240 VAC, 12 to 24 VDC, Output: Relay, transistor output With LCD display, operation buttons, and calendar/clock function 10 I/O points 20 I/O points LED type 10 I/O points ZEN-10C2@ 20 I/O points ZEN-20C2@ This CPU Unit has no LCD, operation buttons, or calendar/clock function.

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. !CAUTION Electric shock, fire, or malfunction may occur. Do not disassemble, modify, or repair the ZEN or touch any of the internal parts. Electric shock may occur. Never touch the I/O terminals, computer connector, or Battery Unit connector while power is being supplied. Electric shock may occur. Do not remove the Expansion Unit connector cover unless an Expansion I/O Unit will be permanently installed. Fire may occasionally occur. Tighten the terminal screws to a torque of 0.565 to 0.6 N·m (5 to 5.3 in-lb). ■ Precautions for Safe Use Please observe the following precautions for safe use of this product. Circuit Design • All interface connectors and battery connectors are live parts. They may not be directly connected to a Safety Extra Low Voltage (SELV) circuit or to accessible conductive parts. For programming units and personal computers use only the connecting cable ZEN-CIF01 (optional accessory) manufactured by OMRON. ZEN-CIF01 provides safe (reinforced) insulation between personal computers and ZEN. • Provide emergency stop circuits, external interlock circuits, limit circuits, and other safety circuits in addition to any provided within the 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. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the overall system. • Outputs from the ZEN may remain ON or OFF due to faults in internal circuits such as output relay fusing or burning, or output transistor destruction. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the overall system. • Fail-safe measures must be taken by the user to ensure overall system safety in the event of broken signal lines or momentary power interruptions. • The durability 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. Connecting Expansion I/O Units • Supply power to both the CPU Unit and Expansion I/O Units from the same power supply and turn them ON and OFF at the same time. • When connecting Expansion I/O Units with DC inputs to a CPU Unit with an AC power supply, the burst noise immunity will be 1 kV (IEC 61000-4-4). • Expansion I/O Units with AC inputs (ZEN-8E1AR) cannot be connected to a CPU Unit with a DC power supply. System Startup and Program Changes • Check the user program for proper execution before actually running it on the Unit. • Disconnect the output lines from the system before testing operation in any system in which incorrect operation can result in injury or equipment damage. • Confirm safety before attempting any of the following operations. • Changing the operating mode (RUN/STOP). • Using the button switches. • Changing bit status or parameter settings. • Double-check all wiring before turning ON the power supply. • Refer to Cycle Time Calculation Method on page 21 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). Installation and Wiring • Do not allow the ZEN to fall during installation. • Be sure that the DIN Track mounting levers, Memory Cassettes, Battery Units, cable connectors, and other items with locking devices are properly locked into place. Improper locking may result in malfunction. • For surface mounting, tighten mounting screws to the following torque. CPU Units: 1.03 N·m max. Expansion I/O Units: 0.46 N·m max. • Use wires with cross-sectional areas of 0.2 to 2.5 mm2 (equivalent to AWG24 to AWG14) for wiring and strip them for 6.5 mm. Handling • The environment of use for the ZEN is "Pollution degree 2" and "Overvoltage category II" specified in IEC60664-1. • Always use the ZEN within the rated ambient operating temperature and humidity. The rated ambient operating temperature is 0 to 55°C (−25 to 55°C for LED-type CPU Units). If the ZEN is used near sources of heat, such as a power supply, the internal temperature of the ZEN may increase, lowering the durability of the ZEN. • Discharge static electricity from your body, e.g., by touching a grounded metal plate, before touching any Unit. • The exterior of the Units will be damaged if it comes into contact with organic solvents (e.g., benzene or paint thinner), strong alkalies, or strong acids. Never allow such substances to come into contact with the Units. • Do not apply voltages exceeding the rated voltages. Internal elements may be destroyed. • Short failures or open failures may result from the destruction of output elements. Do not use loads that exceed the rated output current. Maintenance When replacing a CPU Unit, transfer to the new Unit and confirm all settings for clock data, internal holding bits, holding timers, and counters before starting operation again. Transportation and Storage • Use special packing boxes when transporting the ZEN and do not subject it to excessive shock or vibration or drop it during shipment. • Store the ZEN within the rated ranges. If the ZEN has been stored at −10°C or lower, allow it to stand at room temperature for three hours or longer before turning ON the power supply. ■ Precautions for Correct Use Installation Environment • Do not install the ZEN in the following locations. • Locations subject to radical changes in temperature 33 ZEN V2 Units • Locations with high humidity subject to condensation • Locations subject to excessive dust or dirt • 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 locations 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. • The ZEN is neither waterproof nor oil-proof. Do not use it in locations subject to water or oil. • Use the ZEN within the allowable power supply voltage range. Be particularly careful in locations with bad power supply conditions, e.g., large fluctuations in the power supply voltage. • Do not install the ZEN in locations subject to excessive noise, which may cause the ZEN to fail. • Take appropriate and sufficient countermeasures when installing systems in the following locations: • Locations subject to strong electromagnetic fields • Locations subject to possible exposure to radioactivity Power Supply • Always turn OFF the power supply to the ZEN before attempting any of the following. • Assembling the ZEN • Connecting or disconnecting any cables or wiring • Attaching or removing the Memory Cassette • Attaching or removing the Battery Unit • If the power supply is interrupted for two days or more (at 25°C), the internal capacitor will discharge and internal bit status and the contents of PV areas will be lost or corrupted and dates and times will be reset. When restarting operation after the power supply has been interrupted for an extended period of time, check the system in advance to confirm that no errors will occur. Handling • Connect connectors only after confirming that the direction or polarity is correct. • Failures could result if dust or dirt enters the ZEN. Always connect the connector cover to the computer connector whenever it is not being used. • 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 Difference between ZEN Programmable Relays and PLC Ladder Program Execution on page 32. • Abide by all local ordinances and regulations when disposing of the ZEN. • The Battery Unit (ZEN-BAT01, sold separately) contains a lithium battery. Observe all applicable legal requirements for your area when disposing of the lithium battery. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
