INPUTS

INPUT 1

Digital input from mechanical contact or AC voltage (see order code)

between terminals 1 and 2 with the following function:

- Timer Start/Stop or Start/Reset

- Counter input pulses. Voltage level for AC input is the same as required

power supply.

INPUT 2 (use only if INPUT is from mechanical contact)

Digital input from mechanical contact between terminals 1 and 3 with the

following function:

- Timer reset

- Counter Start/Reset

- Frequency pulses from solid state sensor for revolution check

- Delay

Note: If both inputs are used, with one of two in AC voltage (24, 110 or

220Vac), you have to use an external AC/DC adapter (see connection dia-

gram).

OUTPUTS:

Two relay outputs (5A/220Vac)

OUTPUT1

Available to terminals 8 (NO contact), 7 (common) and 6 (NC contact).

OUTPUT2

Available to terminals 5 and 4 (NO or NC contact) selectable with jumper to

solder.

POWER SUPPLY

AC Voltage is applied to terminals 9 and 10 (110/220V selected with

jumpers to solder).

Voltages available on request: 24Vdc/110/220/120/240/24/48Vac;

Vac 50/60Hz ± 10%; 24Vdc, -10%+20%

With 24 Vdc, polarity is not critical. See Hardware Configuration.

A Display

Real value of current time/count (countdown).

In configuration phase, description of functions and/or parameters flash-

es alternately with value. Flashing of decimal point on right display indi-

cates:

- the display/setting of time 2/count 2 is selected;

- time 2/count 2 is active.

“EEP” alarm message

This message indicates an EEPROM memory fault; if it persists, send

the instrument back to the factory for repair.

E LED signals

The LEDs show the state of the two output relays (LED on = relay ener-

gized) - OUT1, OUT2.

The LEDs show the state of the Input 1 signal (timer input or input puls-

es to counter):

- LED K off (control inactive) corresponds to input open;

- LED K on (control active) corresponds to input closed.

With jumper S5 open and S6 closed, this state can be reversed (see

configuration).

CONTROLS

B FUNCTION Button

Used to access display/setting phase for Time 2/Count 2 setpoint

(decimal point flashes on right display) and confirms modification of

setpoints.

If the F button is not pushed to confirm a change, the new value will

be stored automatically after 5 seconds.

Push the F button for 5 seconds to access the configuration phase.

Scroll the

functions to be set by means of short pulses.

To quit configuration, push the F button again for 5 seconds.

NOTE: It is not necessary to press the F key to display/modify Time

1/Count 1.

D/C Raise/Lower Buttons

These are used to raise or lower the value displayed in order to

change a setting or choose an option.

The speed of raising (lowering) is proportional to the time for which

the key is pressed. The operation is not cyclical.

When the maximum (minimum) value is reached, the raise (lower)

function causes an automatic scale change (or if configured other

than standard, the function remains blocked in the selected scale).

In normal operation, Time 1/Count 1 (setpoint) can be changed

directly. If no button is pushed for about 5 sec, the display returns

to the current active time.

During the Configuration Phase, the raise (lower) button stops the

alternating description/value display. The display shows the value

to be displayed/modified for about 5 seconds.

Accessing the boards

To remove the electronic parts from the case, open the extraction clips.

Power board Fig. 1

To select the supply voltage 110/220Vac (24/240Vac):

-110V (24/120V) - close the two jumpers marked P2 and open the jumper marked S2.

220V (48/240V) - close the jumper marked S2 and open the two jumpers marked P2.

To select AC/DC voltage: double jumper S1 (See Fig. 1 power board, solder side).

AC voltage: since this is the standard version, the two jumpers S1-AC are already on the

printed circuit.

DC voltage: cut the two jumpers S1-AC and solder two jumpers in position S1-DC.

CPU-inputs boards

Hardware protection of configuration.

- Configuration disabled: close jumper S2 and remove jumper S3.

- Configuration enabled: close jumper S3 and remove jumper S2.

The standard version is supplied with configuration enabled.

Selection of relay R2 contact:

NO (normally open) / NC (normally closed).

NO: close NO jumper and remove NC jumper.

NC: close NC jumper and remove NO jumper.

The standard version is supplied with contact configured NO.

6 • PROGRAMMING

POWER BOARD

CPU BOARD

Programming the TIMER:

In normal operation, display Ashows the real value of the active time (if Time 2 is active, the decimal point flashes on the right display).

The setpoints for Time 1 (and Time 2) are set by pressing the Raise/Lower buttons.

If the Timer is active, push the raise or lower button to recall the Time 1 setting, then use these buttons for a new setting. Select Time 2 with the Fkey.

The setting of Time 1 is immediate while Time 2 must be selected using the Fkey. When the setting has been made, press the Fkey to return to normal

operation. If the Fkey + raise button are pressed simultaneously for about 3 sec, the instrument will display the software release.

Programming the COUNTER:

In normal operation, display Ashows the real value of the active count (if count 2 is active, the decimal point flashes on the right display).

The setpoints for Count 1 Time 2/Count 2 are set by pressing the Raise/Lower buttons.

If the Counter is active, push the raise or lower button to recall the Count 1 setting, then use these buttons for a new setting. Select Time 2 / Count 2 with

the Fkey. When the setting has been made, press the Fkey to return to normal operation.

Programming can be disabled by setting the software password to 1 (see Configuration phase, “Pro” function).

Note: the maximum counting frequency is 100Hz.

7 • SOFTWARE CONFIGURATION

Introduction

Configuration (CFG) is performed in a single procedure and consists of 9 settable parameters.

To access Configuration (if the hardware protection has been removed), press the F key until the CFG message appears on display A.

Then press the F key briefly to scroll the various functions (parameters) to be set so that the instrument can be configured as required. The display alter-

nately shows the symbol and the value of the parameter.

The raise and lower buttons stop this alternation so that the value to be seen and/or changed remains on the display. Alternation resumes if no button is

pushed for about 5 sec. Press the F key for about 5 seconds to quit the configuration procedure. The display returns to the “real” time/count.

Configuration parameters are visible only when applicable, depending on the type of operation selected.

Operating modes in range 1÷9

Out=1 Delay at energizing of single relay:

Relay R1 energizes at end of time T1.

- In double time and

- cyclical versions,

relay de-energizes at end of time T2.

Out=2 2 relays: R1 delayed at energizing - R2 instantaneous

R1 - same as Out=1 R2 energizes instantaneously at close of contact IN1 and de-energizes at opening.

Out=3 2 relays in phase:

R1 same as Out=1 R2 same as R1

Out=4 2 relays in opposition:

R1 - delayed at energizing - R2 - delayed at de-energizing

R1 - same as Out=1

R2 - energizes during timing and de-energizes when time T1 has elapsed

- In double time and

- cyclical versions,

R2 remains de-energized for duration of time T2, then re-energizes.

Out=5 2 relays, double time

R1 - same as Out=1

R2 - energizes at end of total time T1+T2 with relay R1 de-energized

Out=6 2 relays, double time

R1 - energizes at end of time T1 (same as Out=1; does not de-energize at end of time T2)

R2 - energizes at end of total time T1+T2

Out=7 Not used

Out=8 Revolution check

2 relays, 2 concurrent times, 2 limits T1 and T2 with T1, T2

Measures time between 2 consecutive pulses of input signal IN.2

Timers T1 and T2 start (countdown) at each rise front of the IN.2 signal.

If interval t between two pulses is greater than T1, relay R1 energizes.

R1 stays energized as long as this (cyclically checked) situation persists.

R1 de-energizes as soon as t<T1.

If interval t between two pulses is less than T2, relay R2 energizes. R2 stays energized as long as this (cyclically checked) situation persists.

R2 de-energizes as soon as t>T2. T2<t<T1- for normal speed (frequency) (within set limits)

t>T1- for low speed (frequency) (below set limit)

t>T2- for high speed (frequency) (above set limit)

Out=9 Control signal delay. Single relay, single timer.

The timer starts and restarts on the 2 change fronts of the control signal.

The timer starts when the IN2 signal switches from OFF to ON; the relay energizes at the end of time T and the timer is reset. The timer restarts when

the IN2 signal switches from ON to OFF; the relay de-energizes at the end of time T. The cycle is repetitive and follows the IN2 signal.

For correct operation, the IN2 signal ON time must exceed delay time T.

ORDER CODE

• WARNINGS

Read the following warnings before installing, connecting or using the device:

• follow instructions precisely when connecting the device.

• always use cables that are suitable for the voltage and current levels indicated in the technical specifications.

• the device has no ON/OFF switch: it switches on immediately when power is turned on. For safety reasons, devices permanently connected to the power

supply require a two-phase disconnecting switch with proper marking. Such switch must be located near the device and must be easily reachable by the

user. A single switch can control several units.

• if the device is connected to electrically NON-ISOLATED equipment (e.g. thermocouples), a grounding wire must be applied to assure that this connec-

tion is not made directly through the machine structure.

• if the device is used in applications where there is risk of injury to persons and/or damage to machines or materials, it MUST be used with auxiliary alarm

units. You should be able to check the correct operation of such units during normal operation of the device.

• before using the device, the user must check that all device parameters are correctly set in order to avoid injury to persons and/or damage to property.

• the device must NOT be used in inflammable or explosive environments. It may be connected to units operating in such environments only by means of

suitable interfaces in conformity to local safety regulations.

• the device contains components that are sensitive to static electrical discharges. Therefore, take appropriate precautions when handling electronic circuit

boards in order to prevent permanent damage to these components.

Installation: installation category II, pollution level 2, double isolation

• power supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on the

device label.

• install the instrumentation separately from the relays and power switching devices

• do not install high-power remote switches, contactors, relays, thyristor power units (particularly if “phase angle” type), motors, etc... in the same cabinet.

• avoid dust, humidity, corrosive gases and heat sources.

• do not close the ventilation holes; working temperature must be in the range of 0...50°C.

If the device has faston terminals, they must be protected and isolated; if the device has screw terminals, wires should be attached at least in pairs.

• Power: supplied from a disconnecting switch with fuse for the device section; path of wires from switch to devices should be as straight as possible; the

same supply should not be used to power relays, contactors, solenoid valves, etc.; if the voltage waveform is strongly distorted by thyristor switching units

or by electric motors, it is recommended that an isolation transformer be used only for the devices, connecting the screen to ground; it is important for the

electrical system to have a good ground connection; voltage between neutral and ground must not exceed 1V and resistance must be less than 6Ohm; if

the supply voltage is highly variable, use a voltage stabilizer for the device; use line filters in the vicinity of high frequency generators or arc welders; power

supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on the device label.

• Input and output connections: external connected circuits must have double insulation; to connect analog inputs (TC, RTD) you have to: physically sepa-

rate input wiring from power supply wiring, from output wiring, and from power connections; use twisted and screened cables, with screen connected to

ground at only one point; to connect adjustment and alarm outputs (contactors, solenoid valves, motors, fans, etc.), install RC groups (resistor and capaci-

tor in series) in parallel with inductive loads that work in AC (Note: all capacitors must conform to VDE standards (class x2) and support at least 220 VAC.
