Features

■

Easy and Simple Programming for Automatic Small-scale Control

Saves Space, Wiring, and Installation Steps

• Versatile functionality in a compact body (70 mm wide

×

90 mm high).

• This single Unit easily provides relay, timer, counter, and time switch functions. Wiring work is greatly reduced because separate wiring is not required for devices such as timers and counters.

Easy Programming

The LCD screen comes with 8 operation buttons on the front panel to enable programming in ladder view format. The LCD screen also has a backlight, making it easier to see when the ZEN is used in dark locations.

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.

Twin-timer Operation Added

Twin-timer operation allows you to set ON and OFF times separately, greatly simplifying intermittent operation.

High-speed Operation

For CPU Units with DC power supply, high-speed operation is possible for input I0 only. (Maximum counting speed: 150 Hz)

Counting Speed of the 8-digit Counter

The maximum counting speed of the 8-digit counter is 150 Hz. When the ladder program volume is large, however, this speed will be less than 150

Hz. Calculate the cycle time and confirm the maximum counting speed using the following formula. The calculation serves as a guide only, so allow a suitable margin in the actual machine.

ZEN Support Software Functions

Note: Always use ZEN-SOFT01-V4 as the Support Software for the V2 CPU Unit.

Creating Ladder Programs

ZEN ladder programs can be created with ease.

Simulating Ladder Programs

The simulation function makes it possible to check whether correct operation is performed without connecting to the ZEN.

Note: The Edit Input Dialog Box is displayed when an input bit is inserted. Timer, counter, and other parameter settings are also set in the Edit Input Dialog Box. They cannot be set in the Edit

Output Dialog Box.

Monitoring Ladder Programs

The operating status can be monitored from the Support Software by connecting to the ZEN using a Connecting Cable (ZEN-CIF01).

Printing Ladder Programs

Ladder programs and I/O comments, as well as timer, counter and other parameter settings can be printed.

Note: Both RS-485 communications and the ZEN monitoring function cannot be used at the same time with Communications-type CPU Units.

The Support Software can also be used to save files and edit comments.

Refer to the ZEN Support Software Operation Manual (Cat. No.Z184-E1-03) for details.

Changes in Comparison with Previous Models

• The power supply and transistor output voltage ranges for CPU Units and Expansion I/O Units with DC power supply has been expanded to

10.8 to 28.8 VDC.

• The width of Expansion I/O Units has been reduced by half and only 8-point models are available.

• The connection method between the CPU Unit and Expansion I/O Units has changed.

• Twin timer operation has been added to timers.

• Multiple-day operation and pulse-output operation has been added to weekly timers.

• An 8-digit counter and 8-digit comparators have been added.

• The accuracy of analog inputs has been increased to

±

1.5% FS.

• The timing accuracy of weekly timers and calendar timers has been increased to

±

15 s or less per month (at 25

°

C).

• Australia and New Zealand Daylight Saving Time (DST) settings have been added.

• 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).

• There is no change to the 8 A per contact for relay output, but the total output for all contacts must be as follows:

Units with 10 I/O Points: 20 A max. (15 A max. for Communications-type CPU Units)

Units with 20 I/O Points: 40 A max.

Expansion I/O Units: 20 A max.

• Always use the ZEN-SOFT01-V4 Support Software for V2 CPU Units.

• Input wiring for CPU Units with DC power supplies differs from that for Pre-V1 CPU Units. Refer to the following diagrams.

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.

!

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 block screws to the specified torque (0.5 to 0.6 N·m) so that they do not become loose.

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 22 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 @ [email protected] -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 mm

2

(equivalent to AWG24 to AWG14) for wiring and strip them for 6.5 mm. If using stranded wires, always connect straight crimp terminals (0.25 to

2.5 mm

2

).

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

• 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 33.

• 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.
