3 Handling the Equipment

This section describes the handling of the display menu and its different options, such as protecting ladder programs, installing filters on inputs,adjusting the display contrast, setting the clock to summer time, etc.

3.1 Main MenuThe following screen is displayed as ZEN receives the power supply:

In the case of any expansion module being connected, pressing the ESC key will monitor the status of the expansion bits.

The main menu is displayed by pressing the OK key on the initial screen, as shown below:

3.2 Selecting the LanguageThe ZEN menu is available in 6 languages, which can be selected as follows (the default language is English)

3.3 Date and TimeAccess to the date and time settings window can be gained by following the menu sequence shown below:

3.4 Protecting ProgramsZEN has a password function, used to prevent incorrect use of the ladder program or to prevent manipulation of settings made by the controller.

The password code may comprise the range 0000 to 9999 (4 decimal numbers).

The password prevents entry to the following points:

Editing ladder programs

Monitorng ladder programs

Changing or erasing the password

Setting the input filter

Setting the node number

The Password screen is displayed immediately any of the different options is selected from the menu. If the password is correct, access to the

screen requested will be given. If not, access will be denied.

3.7 Stabilizing Input OperationsIf the ZEN external input fluctuates, it is possible that the operations will be unstable. To solve this, ZEN is able to filter inputs to stablilize thesignal.

The input filters can be set separately, either for the CPU inputs or for each I/O expansion unit.

Note: The input filter time settings are as follows:

The input filter settings are read when ZEN starts the operation.

3.8 BacklightThe LCD backlight is automatically activated when the operation keys are used. Depending on the setting (see below for more details), this light

will switch itself off 2, 10 or 30 minutes after the function keys have stopped being used. The backlight can also be left activated (setting always in

3.10 Setting SummertimeIn some countries like our own, the time is changed when a certain season of the year comes around. ZEN contains this option, which is knownas summertime.

The following steps must be taken to carry out these changes:

Note: On entering the clock display screen, Summertime is activated and an "S" is displayed in the top right-hand corner to show that this function

has been set.

n OFF delay The timer bit turns to ON mode from the moment the input is triggered until the set time haselapsed on the timer.

O One-shot The set timer bit turns the selected time to ON mode when the trigger input switches from OFFto ON mode.

F Flashing pulse The set timer bit constantly switches from OFF to ON mode while the trigger input remains inON mode



Display Bits

I/O Bit AddressingThe bit input addresses 10 to 15 and the bit output addresses Q0 to Q3 are always allocated to the CPU unit.

Up to 3 I/O expansion units can be added, allocating these I/O points to the X0 to Xb input bits and Y0 to Yb as output bits, remembering the orderof the connected expansion units.

Note:

When the I/O expansion unit does not have I/O points, such as a 4-point input or output unit as shown above, the unused bit addresses are notallocated in the unit and can be used for the following expansion unit.



Display D D0 to D7 8 Displays predefined messages relating to timers,counters and their present values or converted analogvalues.

7 Programming Functions

7.1 Timers (T) and Holding timers (#)ZEN has the capacity to use 8 normal timers and 4 holding timers.

Timer Operation (T0 to T7)

Note: The 'n' code means 'null' (blank code on the console)

Timers The present value of the current timer is reset when ZEN switches from Runmode to Stop mode or when the power supply is turned off.

Holding Timers The present value of the t imer will be maintained even when ZEN switches fromRun mode to Stop mode or when the power supply is turned off. The time willcontinue running when the input 'trigger' is in ON mode again. The ON status ofthe timer bit will also be maintained.It is only supported by the holding timers at connection.

Timer Type Operation Applications

X Timer atconnection

Output is activated whenthe set time elapses onthe input being triggered.

Delay operations in On-status

n Timer atdisconnection

Output is activated fromwhen input switches toON mode until the settime elapses.

Useful for timers, lighting orventilation fans

O Flashing pulsetimer

The set timer bit switchesthe selected time to ONmode when inputchanges from OFF modeto ON mode.

Useful for repetitiveoperations when theoperation to be carried outrequires the same time period

F Flashing pulsetimer

The set timer bit switchesrepeatedly from ON modeto OFF mode, while inputis in ON mode

Useful as an alarm circuit, forvisible or audible emergencyalarms.

7.1.3 Parameter Monitoring on 'Screen Display'

7.2 Using Counters (C)Up to 8 counters can be used in incremental or decremental mode. The present or current value (PV) of each counter and the status of the bits ofeach counter (ON/OFF) are maintained even when the operation mode changes or when there is no power supply.

The counter bit switches to ON mode when the count value (PV) exceeds the set value (present value = set value). The counter is reset and itscorresponding bit turns to OFF mode when the reset input is activated (ON mode). The count input is not effective while the reset input is active.

9 Accessories

9.1 BatteryThe ladder program and all settings are saved on the CPU EEPROM unit, but the calendar, clock, holding timer bits and the timer/counter presentvalues are held by the unit capacitor.

In the case of power supply failure, the data can be stored in the CPU for approximately 2 days (at 25 C) until they are reset.

Installation method:

1. Lean the ZEN-BAT01 battery unit over to one side and insert the clip into the space provided on the left-hand side of the CPU.

2. Connect the battery cable to the CPU connector.

3. And drag the battery clip towards the CPU.

Note: Disconnect the power supply before assembling the battery unit.

9.2 Memory CassetteMemory Cassettes can also be connected to ZEN to save ladder programs and settings and to copy these ladder programs onto other CPU units.

Installation method:

1. Remove the cover from the CPU front connector

2. Connect the ZEN-ME01 memory cassette

Note: Disconnect the power supply before mounting or removing the memory cassette.

Program Transfer

Note:

1. Program transfer includes the ladder program, parameters and all data settings. Normal and holding timers, counters and holding bits presentvalues cannot be transferred.

2. Only error-free programs can be transferred. The program will not be transferred if it contains any type of error.

3. The memory cassette allows 100,000 writes.

Menu OperationSave Transfers the CPU program to the Memory Cassette. Any

program already in the cassette will be overwritten.
