Inputs
All inputs are optocoupled.
Electrical characteristics of the optocouplers
Ƒ
Operating voltage: from 5 to 24V
Ƒ
Permissible current in photocoupler LED:
. Maximum: 25 mA
. Nominal: 10 mA
. Minimum: 3 mA
Ƒ
Maximum power: 50 mW per unit
Ƒ
Maximum operating frequency:
200 kHz (Pulse time > 2
P
s) for tachometer input.
10 kHz object sensor, parallel interface and miscellaneous signals.
Photocell
The photocell is connected to connector C1 (C2 for head 2). This connector is linked to the
DTOP and COM DTOP inputs on the industrial interface board.
The sensor is activated when an object passes in front of it, and sends a signal to the
printer to start printing.
The DTOP input is filtered to a minimum of 100
P
s to avoid interference. This value can be
programmed.
Disable the object sensor
The VALIMP and COM VALIMP inputs are used to disable the DTOP object detection
signal. These inputs can be linked to any accessory or system, which meets the
specifications indicated below.
Tachometric generator
In cases where the conveyor speed is variable, it is necessary to connect a tachometric (or
tacho) generator with open collector output to sequence printing operations.
The tacho is connected to connector T1 (T2 for head 2). This connector is linked to the
TACHY and COM TACHY inputs on the industrial interface board.
