INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail. For optimal operation and long life, adequate ventilation must be provided. Avoid positioning ducting or other objects that obstruct the ventilation slots. Avoid mounting modules over heat-generating equipment. Installation in the bottom part of the electrical panel is recommended.
CAUTION These are open type devices intended for installation in a final casing/panel that offers mechanical protection and protection against the spread of fire.
SETTING THE DIP-SWITCHES
CAUTION
Dip-switches must be set with the power supply disconnected from the module, to avoid any damage to the module.

FILTER SETTING:
SW1: FILTER 1 2 3 4
FILTER ON FILTER OFF

If you have an unstable input frequency, you can set a filter to stabilize the output signal. To set this filter, simply position dip-switch no.1 of SW1 to ON (move it upwards).

INPUT FREQUENCY SETTING: Multiplier setting
SW1: MULTIPLIER 1 2 3 4
X 0.0001 X 0.001 X 0.01 X 0.1 X 1 X 10
Frequency setting selectors

It is possible to easily set the full scale frequency of the input signal. The three rotary selectors allow you to set a value which, multiplied by the multiplication factor, will give the input full scale frequency.
Example 1: if you have a full scale value of the input frequency = 563 Hz, you will have to set the hundreds selector (100’s) to 5, the tens selector (10’s) to 6, and the units selector to 3 (1’s) and set the multiplier x1 (563 x1 = 563Hz).
Example 2: if you have a full scale value of the input frequency = 7850 Hz, you will have to set the hundreds selector (100’s) to 7, the tens selector (10’s) to 8, and the units selector to 5 (1’s) and set the multiplier x10 (758 x10 = 7850Hz).
NOTE 1: The hundreds (100’s) selector cannot be set to 0; the minimum full scale is therefore 0.01Hz.
NOTE 2: The “Error” LED flashes if the input frequency is lower than that indicated in the table or higher than the set full scale.

N.B.: Dip-switches and rotary selectors must be set with the power supply disconnected from the module, to avoid any damage to the module.

AVERAGE PULSE SETTING: SW1: AVERAGE PULSES 5 6 7 8
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

In the event that there are input signals with a cyclically unstable frequency, it is possible to set a number of pulses on which the frequency measurement will be calculated.
Example: the input signal is provided by a proximity sensor which detects the passage of some bolts mounted on a wheel; if these bolts are not equidistant, there will be an unstable frequency value at the output of the sensor and consequently an unstable value of the voltage and/or current at the output of the Z111 module. By setting the number of bolts applied to the wheel as “average pulses”, for example 10, as the number of pulses for the average, the instrument will count 10 pulses and then divide the time elapsed between the first and last pulse by 10; this operation will allow a very stable signal as output from the module.
NOTE: if you do not want the average of the input pulses to be carried out, leave all the dip-switches of the SW7 selector in OFF (downwards).
N.B.: Normally the minimum measured frequency is 0.001 Hz. When pulse averaging is set above 6, the minimum frequency becomes n / 6000.
Example: pulse average = 8, f. min = 8/6000=0.00133Hz

Dip-switch number 9 of the SW1 group allows you to select the output voltage. Dip-switch number 10 of the SW1 group allows you to set the output with or without zero elevation.

HYSTERESIS
MI00623-1-EN

HYSTERESIS CALIBRATION:
This operation must only be carried out when the “Variable reluctance” input is used.
For calibration, after appropriately setting the DIP-SWITCH and the full scale frequency, it is necessary to provide an input signal with an amplitude similar to the working one. Using a screwdriver, rotate the hysteresis trimmer (T1) completely clockwise and then slowly rotate the trimmer anti-clockwise until the “INPUT” LED lights up (flashing in relation to the applied frequency). At this point, further rotate the trimmer clockwise by approximately 10% to have a safety margin on the calibration.
NOTE: remember that the minimum signal amplitude is 100mV.

CAUTION
To meet the electromagnetic immunity requirements: – use shielded signal cables; – connect the shield to a preferential instrumentation earth system; – separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc…).
CAUTION
Use AWG size 30-12 or two 24-16, torque 5 lb in. (For UL approval)
