ʄ LED status
These LEDs provide a visual indication that specific output signals from the printer or input
signals from an external device connected to the board are operating correctly.
ID LEGEND COMMENTS
LED1
(green)
TOP2 Signal from DTOP2 input is present
(LED flashes in time with the photocell signal).
LED2
(green)
TOP1 Signal from DTOP1 input is present
(LED flashes in time with the photocell signal).
LED 3
(green)
TAC2 Signal from TACHY2 input is present. (LED flashes in
time with the tachometer pulses).
LED4
(green)
TAC1 Signal from TACHY1 input is present. (LED flashes in
time with the tachometer pulses).
LED5
(green)
FIN2 The LED goes on when the VALFINALIMP2 signal
from the printer changes to logic level 0 - i.e. 0V
(active status)
Indicating that counter 2 on head 2 has reached its
final value.
LED6
(green)
SP2 The LED goes on when the SPROG2 signal from the
printer changes to logic level 1 - i.e. +5V (active
status) in SPROG2 mode (jumper S7-3).
The LED goes on when the SPROG2 signal from the
printer changes to logic level 0 - i.e. 0V (active status)
in BUSY2 mode (jumper S7-1).
In both cases, when the LED is on idicates that head
2 is printing.
LED7
(green)
RC2 Signal from the RAZC2 input is present. (LED flashes
in time with the command signal).
LED8
(green)
INC2 Signal from the INCC2 input is present. (LED flashes
in time with the command signal).
LED9
(green)
FIN1 The LED goes on when the VALFINALIMP1 signal
from the printer changes to logic level 0 - i.e. 0V
(active status).
Indicating that counter 1 on head 1 has reached its
final value.
