Input/Output connections
1.3.2
ALDEF: fault output
This output is used for announcing a printer malfunction which prevents printing.
It can also be activated on start-up if the printer is not ready.
This output can be connected to a flashing light or audible alarm and in addition, to the conveyor
power supply to halt the production line.
This output has two types of contact: a dry break contact (normally closed) and a dry make contact
(normally open)..
The electrical characteristics and the operational mode of the Default outputs are identical to the
Alarm outputs (see preceding sub-section).
1.3.3
SYNC: message synchronization
The SYNC + and SYNC - terminals of the industrial interface cassette are used for providing a
calibrated pulse while the message is being printed.
The message synchronization output uses the output characteristics of a high-speed photocoupler
with an open collector photo-transistor.
Operating characteristics:
• Maximum output current Is: 16 mA.
• Maximum operational voltage: 24 V.
1.3.4
ETAT: print status
This output can only be used if it is configured in the printer:
• (1) In the PRINTER PREPARATION menu, INITIALIZATION sub-menu, PRINTER
function, MISCELLANEOUS step, COUNTING line parameterized for Tach. puls. nb.
• OR (2) in the MESSAGE EDITING menu, PARAMETERS sub-menu, COUNTER function,
ACTIVATE OUTPUT line
x
.
It changes state, depending on the printer configuration, when a certain number of tacho pulses is
reached (1) OR when the counter reaches its final value (2).
The operating characteristics are exactly the same as for the SYNC output.

Utilization of contact normally open,
the circuit closes in case of an fault.
Utilization of contact normally closed,
the circuit opens in case of an fault.
