COUNTERS P GE
– The counters page displays CNT1...4 counters.
– It is possible to count the number of times an input is activated, or a limit has been overcame etc. The count condition is defined by Counter source
parameters.
– For every counter, it is possible to define a description and a unit of measure with a free text, for instance litres, kg, etc.
– It is possible to define a conversion factor between the number of pulse counts and the measurement shown on display. This function can be obtained by
specifying a multiply and a divide factor. For instance, setting the multiplier k to 3, for every pulse count, the value shown will be incremented 3 times. If
instead, a divider is set to 10, then the value will be incremented by one only after 10 pulses have been applied to the input. With a combination of multiply
and divide factor, any ratio between counts and measurement can be achieved.
– If the counter has no divide factor, the screen will indicate the counter without fractional digits, otherwise the counter will be displayed with two decimal
digits.
– The counters can be cleared by means of commands menu or by means of the Reset source signal, defined by dedicated parameters.

P SSWORD CCESS
– The password is used to enable or lock the access to the setting menu (set-up) and to commands menu.
– For brand-new devices (factory default), the password management is disabled and the access is free.
If instead the passwords have been enabled and defined, then to get access it is necessary to enter the password first, specifying the numeric code through
