FEMA ELECTRÓNICA . Series M . M60-C1

6

Special  working  mode  for  applications  with  low  frequency  signals. 
Applies to ratemeter (‘

rt.6

’), ratemeter quadrature (‘

rtq.7

’) and peri-

odmeter  (‘

Prd.8

’).  The  ‘

SLOW

’  mode  allows  to  measure  slow  fre

-

quencies down to 1 mHz (0,001 Hz) and is functional up to 200 Hz.

The ‘

SLOW

’ mode provides the fastest response time possible for a 

given application, calculating the frequency and the period based on 
the time between consecutive impulses.

The ‘

SLOW

’ mode needs to define the parameter ‘

maximum waiting 

time

’ to a value between 1 and 1000 seconds. If this time expires 

without  a  single  impulse  being  received,  the  reading  jumps  to  ‘0’ 
(both for ratemeter and periodmeter modes). The ‘

GATE

’  parameter  

is not used if ‘

SLOW

’ mode is active.

In  ‘

ratemeter quadrature

’  (‘

rtq.7

’)  mode,  the  activation  of  the 

SLOW

’ mode calculates the frequency based on the time between 

consecutive  impulses  received  on  channel  A,  and  calculates  the 
sense  of  turn  (clockwise  or  counter-clockwise)  by  comparing  each 
impulse with the state of channel B. The ‘

edge

’ parameter is fixed to 

a ‘

1--1

’. Typical application for quadrature frequency measure with 

two  inductive sensors at low frequency.

1.13 

Function ‘Trigger Sense’

Special working mode for counter applications with high frequency 
signals, up to 250 KHz. Applies only to the counter mode (‘

cn.1

’).

The activation of the ‘

FAST

’ mode configures the signal detection by 

rising edge. The first edge detected, either rising or falling edge, after 
the instrument restart (power-up, or configuration change) is used 
for internal initialization and will not be counted as impulse.

1.14 

Function ‘cycle counter’

1.15 

‘SLOW’ mode

The trigger level is automatically configured when selecting a sensor 
from the ‘Sensor / Configuration’ (‘

SnSr

’ / ‘

Auto

’) menu list. the trig-

ger level can be also manually modified from the ‘

SnSr

’ / ‘

TrIG

’ menu 

entry. The selected value applies to channels ‘A’ and ‘B’ (the reset has 
a fixed trigger level at 2.5 Vdc).

At the ‘

SnSr

’ / ‘

TrIG

’ menu, the instrument shows the trigger level 

and two vertical leds to the left. These leds inform in real time about 
the status (‘0’ or ‘1’) of the input channels ‘A’ and ‘B’. When the led 
switches between up and down position, it indicates that impulses 
are being detected at the input. If the instrument does not detect 
impulses, the led positions remain fixed..

The  counter  modes  allow  to  activate  a  reset  function  (to  ‘0’  or  to 
‘preset’ value) when an alarm setpoint is reached. With this configu

-

ration, the instrument counts in cycles, counting from the instrument 
preset value up to the alarm setpoint. Each cycle is counted and ac

-

cumulated into an internal memory, accessible through the ‘fast ac

-

cess’ menu (key UP (

(see section 1.19.12)).

To reset the memory of cycles, visualize the value at the ‘uP’ menu, 

then press the (

) key and the ‘

reset.
