TRIGGER SIGNAL SELECTION
The trigger signal which initiates the print cycle can be either a DC voltage or taken
from a pair of normally open contacts. The option is selected by moving the blue
jumpers at the rear of the main printer control card. When supplied, the board is
configured to accept a DC print signal.
1.
Horizontally mounted boards are normally configured to accept a DC print
signal within the range 10 to 50 volts (polarity unimportant), and the blue
selector jumpers are pegged north-south i.e. sitting parallel to each other, see
figure 1.
2.
For triggering from a normally open contact source such as a relay,
microswitch or foot switch, the selector jumpers should be set east/west i.e. in
line with each other, see figure 2.
N.B. Vertically mounted boards for use in DIN41494 (“Eurocard”) enclosures are
pegged east-west. Both print signal options are then available and can be selected
by suitable wiring to the PCB connector within the enclosure.
