PROGRAMMING OF THRESHOLD
For THRESHOLDS programming access, proceed as follow:
- Press key ‘PRG’ in impulsive mode; on display appears:
Ë1 <
S.1 = THRESHOLD 1, value programmable between 000000 and 999999 of the CNT1 INC counter that
executes the increment of the counting. If it programmed = 0 the set point control is excluded.
Ë2 <
S.2 = THRESHOLD 2, value programmable between -99999 and 999999 of the CNT2 DEC counter that
executes the decrement of the counting. If it programmed = 0 the set point control is excluded.
Key ENT confirms the data and passes to the successive programming. In order to exit the programming, press key PRG.
PROGRAMMING OF THE OPERATION PARAMETERS
The programmable parameters are divided in two groups and protect with a 4 figures code.
In order to approach the programming, proceed in the following way:
- Press key PRG for about 2 sec. On the display appears:
GROUP 1
:
insert code

and press

t.’ = Automatic Time Reset of CNT1 INC counter, programmable from 00,0 up to 99,9 sec. This
parameter allows to the instrument to operate in automatic mode. When the counting reach the S1 value
automatically it resets the counting, excites the relay RL1 and restart the counting without lose impulses.
The relay RL1 remains ON for time programmed in t.’ programming. If the reset time programmed in t.’ is =
0 (00,0) the instrument operates in manual mode.
Particular case: if the set up time t.’ is smaller of the time employed from the count to arrive to the values
of S.1 or S.2, the relative relays will never come unactived.
t.” = Automatic Time Reset of CNT2 DEC counter, programmable from 00,0 up to 99,9 sec. This
parameter allows to the instrument to operate in automatic mode. When the counting reach the S2 value
automatically it resets the counting, excites the relay RL2 and restart the counting without lose impulses.
The relay RL2 remains ON for time programmed in t.” programming. If the reset time programmed in t.” is
= 0 (00,0) the instrument operates in manual mode.
Particular case: if the set up time t.’ is smaller of the time employed from the count to arrive to the values
of S.1 or S.2, the relative relays will never come unactived.
F’ = 4 digits multiplier Factor of CNT1 INC counter, programmable from 0,1 to 9.99999.This parameter
allows to convert the number of the input impulses, showing them on the display in another format. If it
programmed = 0 it comes reprogrammed automatically to 1. If a value lower than 1 is inserted, it obtains
the division of the impulses. Es. I want to divide for 25 the impulses in input; calculation 1 : 25 = 0.04.
Attention: the variation of the value of the multiplying modifies automatically the value of the counting.

In. ’ = Input CNT1 = Fast - Slow - Medium. This programming allows to set the input of CNT1 counter to
read electromechanical signals or logical signals:
In = F. Fast, input CNT1 can read logical signals up to 20 KHz.
In = S. Slow, input CNT1 can read electromechanical signals up to 25 Hz.
In = M. Medium, input CNT1 can read electromechanical or logical signals up to 100 Hz.
In. ” = Input CNT2 = Fast - Slow - Medium. This programming allows to set the input of CNT2 counter to
read electromechanical signals or logical signals:
In = F. Fast, input CNT2 can read logical signals up to 20 KHz.
In = S. Slow, input CNT2 can read electromechanical signals up to 25 Hz.
In = M. Medium, input CNT2 can read electromechanical or logical signals up to 100 Hz.

SUP’ = Programming of Superior counting of CNT1 INC counter.
SUP.’ = Y ; Superior counting active; when the counting reaches the threshold, the instrument actives the
RL1 relay and continues to count. (valid only with t’ = 0).
SUP.’ = n.; Superior counting excluded.
