EPT031055 Issue 2 September 2017 2-37
Pin description
• Pin 1: L1_SOURCE - Positive Interlock Source / +24V floating
This pin delivers a current limited 24V source and can only be used to
• drive Pin 2, Pin 3 and Pin 7 of this connector.
• Pin 2: PRINT_GO - Print Start Input
For external “print go” this pin can be driven with 24V delivered by pin
1.
• Pin 3: IL1_INP - positive Interlock1 Input
This pin is used as input for the first interlock loop.
• Pin 4: L2_GND - GND pin interlock loop 2
• Pin 5: IL2_INP
This pin is used as input for the second interlock loop.
• Pin 6: Printer Ready Output
This output opto driver is switched on when the printer is ready to
print. This output opto driver is protected with an auto-resetting fuse
with a current limit of 100 mA. The output voltage is +24V floating. The
appropriate GND is delivered on pin 4.
• Pin 7: EXT_LSTART_IN - External Laser Start Input
The laser can be switched on by placing a push button or a switch
between pin1 (current limited 24V) and pin 7 (External Laser Start In).
This input is internally working in parallel to the other (X4 and X59)
Laser Start Inputs. Thus, applying of constant voltage at this pin will
suppress edges coming from the other Laser Start Inputs.
