OPERATIONAL MODE 2 

ABSOLUTE/RELATIVE POSITION VISUALISER WITH TWO SETTABLE THRESHOLDS 

FUNCTIONS 

 

Absolute/relative visualisation (see par.Operating Specifications) 

 

2 multiplying factors selectable by input (a different number of 
decimals can be set for the second factor – see ‘Specific 
setting’) 

 

Count load 

 

Display/count block 

 

2 alarm outputs 

MAIN DISPLAY PAGE 

The display shows the value of the count record multiplied by the 
set factor. Positive numbers are shown without sign indication, 
while negative numbers are precedeed by the minus sign; values 
exceeding -99999 are displayed without – sign, with the first digit 
flashing.  

ALARM THRESHOLDS 

Two alarm thresholds, called positive and negative stroke ends,  
can be set; they are enabled by comparison, respectively for  

 

and  

 value than the count record. 

Alarms can be enabled either in comparison with the absolute 
record or with the relative record (see ‘Specific setting’). 

OPERATING MODE 

VALUE SETTING BY KEYBOARD 

During the setting phase of a numerical value a dot flashes on the 
right display side. 
The key 

R  

sets the value to 0. 

The 

Arrow keys

 modify the value. 

The minus sign is obtained by pressing the 

Arrow key 1

 until 

exceeding number 9. The max negative set is –99999 

SETTING THE STROKE END VALUES (free setting) 

The positive stroke end set phase  is accessed by pressing the 
key

 P1

: the display shows 

FC POS

  followed by the current value. 

The value is compared for  

 with the absolute or relative count 

record value to enable or disable output 1. 
Modify the value with the 

Arrow keys

, then press 

P1

 again to 

store the new value and switch to the negative stroke end set 
phase. The display shows 

FC NEG

  followed by the current value. 

The value is compared for 

  with the absolute or relative count 

record value to enable or disable output 2.  
Modify the value with the 

Arrow keys

, then press 

P1 

again to 

store the new value and switch back to the main display page. 

VISUALISATION MODE SELECTION 

Pressing 

P2 

 switches the visualisation from the ABSOLUTE 

RECORD to the RELATIVE RECORD and vice-versa. A dot 
flashes on the display left side as the relative record is displayed.

 

RELATIVE RECORD RESET 

Pressing the key 

R

 the display shows the flashing message

  

rESEt. 

Press 

R

 again to reset the record or 

F

 to leave the phase. 

INPUTS 

CM78N-C02 is equipped with three inputs performing the 
following operations: 

IN1 

= absolute value loading 

IN2

 = multiplying factor 1-2 selection 

IN3

 = count block or visualisation block  

IN1: ABSOLUTE VALUE LOADING 

On the input  

IN1 

closure front  the LOAD value is entered into 

the absolute count record. 

IN2: MULTIPLYING FACTOR 1-2  SELECTION 

Closing input 

IN2

 the display indication is switched from: 

Displayed RECORD = COUNT x FACTOR 1 
 

 

to 

Displayed RECORD = COUNT x FACTOR 2 

The number of displayed decimals corresponds to the setting 

Factor 2 decimals’ 

(see ‘

Specific setting’

). The LOAD and 

STROKE ENDS values are also converted automatically. 

IN3: VISUALISATION/COUNT BLOCK 

If the 

count block 

function was selected, the pulses count is 

stopped by closing input 

IN3.

 

If the 

visualisation block 

function was selected, the display update 

of the pulses count is suspended when closing input 

IN3

The input pulses count goes on and the updated value is 
displayed when input 

IN3 

is opened again.  

OUTPUTS 

The instrument is equipped with 2 alarm signal outputs. 

OUT 1

 = Positive stroke end 

OUT 2

 = Negative stroke end 

PARAMETERS SETTING 

Press the key 

F

 and, when the display shows 

Ch.Set,

 digit the 

key sequence 

P2 F P1

 within 5 seconds to access the 

parameters setting phase. 
During the setting phase of a numerical value a dot flashes on the 
right display side. 
The key 

R  

sets the value to 0. 

The 

Arrow keys

 modify the value. 

The minus sign is obtained by pressing the 

Arrow key 1 

until 

exceeding number 9. The max negative set is –99999. 
Press

  F

 to confirm the set value and switch to the following 

parameter. 

PARAMETERS LIST 

Load (setting under constants key) 

The display shows 

LoAd

 followed by the current value. 

The LOAD  value is stored into the count record by closing input 

IN1

Output 1 Excitation Time (for selection: timed pulse outputs

The display shows 

tout 1 

followed by the current value of output 

1 excitation time expressed in seconds. 
Default value 0.3 S. 
Mimimum setting 0.1 S, max setting 25.0 S. 

Output 2 Excitation Time (for selection: timed pulse outputs

The display shows

 tout 2 

followed by the current value of output 

2 excitation time expressed in seconds. 
Default value 0.3 S. 
Mimimum setting 0.1 S, max setting 25.0 S. 

Stroke ends (setting under constants key) 

The display shows 

FC POS

. followed by the current value. 

The  value is compared with the count record value to enable or 
disable output 1. 
After confirming the positive end stroke value the display shows 

FC nEg.

 followed by the current value. 

The  value is compared with the count record value to enable or 
disable output 2. 

Multiplying Factors 1 – 2   

The display shows 

FAtt.n   

followed by the current value. Factor 

1 is used when 

IN2

 is open, Factor 2 is used when 

IN2

 is closed. 

After confirming the second value the display switches to the 
main page. 
Factors range values: 0.01000/9.99999.
