DESCRIPTION OF THE FRONTAL KEYBOARD
ø
YELLOW
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
YELLOW
The key 'UP ARROW' in normal operating phase it enter and exit to the Totalizer.
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
DC POWER
(inputs 1-2) 24VDC Power Supply Input of the instrument.
AC POWER
(inputs 3-4) AC Power Supply Input of the instrument; it can be to 24 - 110 - 230 VAC in according to demand.
24 VDC - 80mA
(inputs 5-6) 24 VDC - 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and amplified
proximity.
START
(inputs 7) START Input that execute the timing starting as the programming mode; it’s configurable in Positive
(PNP) or Negative (NPN) logic by the dip switches on the rear.
RESET
(inputs 8) RESET Input that execute the timing reset; it’s configurable in Positive (PNP) or Negative (NPN) logic
by the dip switches on the rear.
INHIBIT
(inputs 9) INHIBIT Input that execute the timing Inhibit; it’s configurable in Positive (PNP) or Negative (NPN) logic
by the dip switches on the rear.
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
:
in order to approach the parameters of group 1, insert code
2357
and press
ENT
SCL. = Time Scale. Selection of the maximum time scale of the timing. It’s possible to choose
between 4 different time scales:
1 = 99m59s99c - 2 = 99h59m59s - 3 = 9999h59m - 4 = 9999s99c
