DESCRIPTION OF THE FRONTAL KEYBOARD
ø
WHITE
The key 'LEFT ARROW' in normal operating phase visualizes, blinking, all the programmings executed without the
limitation of the insertion code. The time of scansion of the programmings is given from the pressure of the same
key. It exits automatically from this phase after 5 sec of the last pressure of the same key.
In programming phase it moves the cursor of the figure towards left of a step, than at the beginning it is on the right
side first one on the. At the end it resumes from the first one to right.
ù
WHITE
The key 'UP ARROW' in normal operating phase visualizes the totalizer of impulses.
In programming phase it increases the value of the blinking figure.
ú
BLUE
The key 'PRG' pressed for 2 sec. allows to enter in the programming phase, visualizing on display C.0000.
In the programming phase, pressing key 'PRG' impulsively, it exits from the programming phase. The instrument exits
automatically from the programming phase, 60 sec. after the pressure of the last key.
û
GREEN
The key 'ENT/RES' in normal phase of counting has the 'RESET' function, with the modalities to it attributed in the
programming phase.
In programming phase it confirms and memorizes the visualized data and passes to the successive function. If it has
arrived to list end it resumes from the beginning.
INPUTS / OUTPUTS DESCRIPTION E SERIES
AC POWER SUPPLY
(inputs 1-2)
AC Power Supply Input of the instrument; it can be to 24 - 110 - 230 VAC in according to demand.
DC POWER SUPPLY
(inputs 3-4)
24 VDC Power Supply Input of the instrument; input 3 (-), input 4 (+).
12 VDC - 80mA
(inputs 12-13)
24 VDC – 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and proximity amplified.
PRI
(input 10)
Input used for the polarization of the count and command inputs : connecting the PRI output to input 13 it configures the instrument in
Negative logic (NPN), connecting the PRI output to input 12 it configures the instrument in Positive logic (PNP).
INPUT
(input 11)
Input of count adapted for electromechanical and logical contacts, encoder and 3 wires proximity amplified, configurable in Positive
(PNP) and Negative (NPN) logic through PRI input (10).
RESET
input 7)
Input of RESET that executes the reset of the visualized count showed on display at the moment of its activation.
INHIBIT
(input 8)
Input of count inhibition: when activated it blocks the count of the normal counter and the totalizer.
