Accessing the boards
To remove the electronic parts from the case, open the extraction clips.
Power board
To select the supply voltage 110/220V (24/48Vac; 120/240V):
110V (24/120V) - close two jumpers P and remove jumpers S;
220V (48/240V) - close two jumpers S and remove jumpers P;
24Vdc available on request (see order code).
CPU-inputs boards
Hardware protection of configuration.
- Configuration disabled: close jumper S9 and remove jumper S10.
- Configuration enabled: close jumper S10 and remove jumper S9.
The standard version is supplied with configuration enabled.
Digital logic input 1 “IN1”
Active when closed: close jumper S7B
Active when open: close jumper S7A
The standard version is supplied with IN1 active when closed.
Selecting hardware filter on inputs
You can insert 3 different low pass filters for each input by installing the appropriate jumpers.

Standard version
Setpoint variation can be disabled in any application by setting the software password to 1 (Pro function).
Programming the TIMER (Function Typ=0)
In normal operation, display A shows the real value of the active time. Setpoint values for Time 1 (and Time 2) are set with the raise/lower buttons. Time 1 is
changed immediately; Time 2 is selected with the F key. They are managed with the following inputs:
- IN1 START/STOP
- IN2 RESET
- IN3 HOLD or UP/DOWN (see configuration of IN3 functions).
If the function of IN3 is defined as UP/DOWN, it causes inversion of the current value of Time 1; Time 2 maintains its direction.
If the timer is configured to down (Fun=0), it loads the preset value and counts down toward zero; by closing IN3 (if configured to “active when closed”), you tempo-
rarily reverse the direction of time 1 to up until Full Scale is reached.
If the timer is configured to up (Fun=1), it starts from zero and counts to Set, closing IN3 (if configured to “active when closed”) and temporarily reversing the
change in time 1 to down. The HOLD function freezes the display only: the timer function stays active.
Programming the COUNTER (function Typ=1)
In normal operation, display A shows the real value of the active count.
The setpoints for Count 1 Time 2/Count 2 are set by pressing the Raise/Lower buttons.
Time 1 is changed immediately, Select Time 2 / Count 2 with the F key.
The Counter is managed with the following inputs:
- IN1 CLOCK (max. frequency 5KHz)
- IN2 RESET
- IN3 HOLD or UP/DOWN (see configuration of IN3 functions).
A prescaler factor can be inserted on the clock: x2, / 2, / 10, / 100.
The displayed/set value can be expressed in engineering units by setting the MUL and DIV functions.
Example 1:
By setting MUL = 1 and DIV = 60, you reset the parameter so that the display shows:
no. real pulses • MOL
o. real pulses • 1
o. real pulses
=--------------------------------- = ---------------------------- = -------------------------
DIV
60
60
The setting corresponds to : Set value • DIV
------------------------------
MOL
For example, if you set 1, you get: 1
•
60
------------ = 60
1
i.e., with the counter configured up, 60 real pulses have to be counted before “1” is reached.
The count sequence displayed
0, 1, 2, …. etc., corresponds to a real count of 60 pulses
0, 60, 120, ….. etc.
