INSTALLATION RULES

The Z111 modules have been designed for mounting on DIN 46277 guides in vertical

position.

For long-lasting and optimum working life, the module(s) must be ensured adequate

ventilation. Make sure to position the cable raceways and any other objects in such

way as to avoid clogging the ventilation slots.

Also avoid positioning the modules above equipment that generates heat. For this

reason, we recommend performing installation in the lower part of the panel.

TAXING WORK CONDITIONS:

The following are considered taxing work conditions:

elevated power supply voltage (> 30V DC / > 26 V AC)

providing power supply to sensor input.

use of the active current output.

When paired modules are installed, inthey may require separation by at least 5 mm

the following cases:

With panel temperatures of more than 45°C in concomitance with at least one of the

taxing work conditions above.

With panel temperatures of more than 35°C in concomitance with at least two of the

taxing work conditions above.

ELECTRICAL CONNECTIONS

POWER SUPPLY

INPUTS

We recommend using shielded cables for the connection of the signals; the shield must

be connected to a designated ground connection for the instrurmentation. We also

discourage passing the wires near the power supply cables for inverters, motors, or

induction ovens, etc.

19 ÷ 28 V

19 ÷ 40 V=

The power supply voltage must be between 19 and 40 V DC

(polarity not important), 19 and 28 V AC; also see the section

entitled“INSTALLATIONRULES”.

The upper limits must never be exceeded at the risk of

creatingseriousdamagetothemodule.

The power supply source must be protected against all risk of

modulemalfunction

by the use of an well sized fuse.

NOTE : In order to permit the use of the variable reluctance type input, the internal

Before setting the internal jumpers, the container's lateral closing panel must be

removed by pulling it slightly outward. The instrument is supplied with internal jumpers

set for standard inputs.

Thisoperationisonlyperformedwhenthe“variablereluctance”inputisused.

For the hysteresis calibration, after first correctly setting the internal jumpers and the full-

scale frequency, a tester must be connected tothe device's output (it makes no difference

whether the voltage or current output is used) and an input signal must be provided; then

using a screwdriver, rotate the hysteresis trimmer completely counter-clockwise (the

tester should indicate 0) and then the trimmer must be slowly rotated clockwise until the

testerprovidesastableinput reading.Atthispoint,rotatethetrimmerclockwisebyaround

NOTE : remember that the minimum signal amplitude is 100 mV.

Filter OFF

Filter ON

Whenever the input frequency is unstable, a filter can be set

to stabilise the output signal. In order to set this filter, position

SW6 ONdip-switch no. 1 in the position (by shifting it

upwards).

N.B.: The dip-switches must be set after first

disconnecting power supply from the module in order to

avoid damaging the module.

INPUT FREQUENCY SETTING

Multiplier setting Frequency setting selectors

The input signal full-scale frequency can be easily set.

The three rotating selectors permit the setting of a value which when multiplied by the

multiplication factor will provide the input signal full-scale frequency.

Example 1 :

Example 2 :

NOTE 1 :

NOTE 2 :

if the input frequency full-scale value = 563 Hz, the hundredths (100's)

selector must be set to 5, the tenths (10's) selector must be set to 6,

and the units (1's) selector must be set to 3. The multiplier must be set to

x 1 (563 x 1 = 563 Hz).

if the input frequency full-scale value = 7850 Hz, the hundredths (100's)

selector must be set to 7, the tenths (10's) selector must be set to 8,

and the units (1's) selector must be set to 5. The multiplier must be set to

x 10 (7850 x 10 = 7850 Hz).

The hundredths selector (100's) cannot be set to 0; the minimum full-scale

value must therefore be 0,01 Hz.

The "Error" led blink if the input frequency is less lower than the values

indicated in the table or more than selected fullscale.

NOTE: Dip-switch and rotating selector setting must be performed after first

disconnecting module power supply in order to avoid damaging the module.

PULSE AVERAGE SETTING

Whenever the input signals present cyclically unstable frequency, a number of pulses

on which the frequency measurement will be calculated can be set.

Example : the input signal is provided by a proximity sensor that indicates the passage

of a number of bolts mounted on a wheel; if these bolts are not positioned

at equal distances, an unstable sensor output frequency value will occur

and this will create an unstable module Z11 output current and/or voltage

value.

By setting the number of bolts applied to the wheel, such as 10, for

example, as the “pulse average” , the device will count 10 pulses and then

divide the time that elapses between the first and the last pulse by 10. This

operation will permit an extremely stable module output signal to be

obtained.

SW7 - PULSE AVERAGE NOTE : if pulse average calculation is not

required, leave all the selector dip-SW7

switches (shifted down).OFF

NOTE: Dip-switch setting must be

performed after first disconnecting module

power supply in order to avoid damaging

the module.

NOTE: The minimum measured frequency is

normally . When the pulse average is0.001Hz

set over , the minimum frequency will be6 n /

6000.

Ex: pulse average = 8 ,

f.min = 8/6000 = 0.00133Hz.

MI00035 -E9 ENGLISH - 8/8

OUTPUT SELECTION

SW1 unit dip-switches number 1 and 2 permit

setting the setting of the output with or without

zero elevation respectively.

SW2 unit dip-switches permit the selection of

the output voltage.

NOTE: Dip-switch setting must be

performed after first disconnecting module

power supply in order to avoid damaging

the module.
