5. Work station safety
To ensure security and productivity, read this manual before starting-up the equipment.
Instructions for use and warranty limitations
• This marking equipment is designed to function at a room temperature between 5 0C (41 0F) to 45 0C (113 0F).
• Position the Control Unit horizontally, in a dry, ventilated area, at least 20 cm (7.874 in) from the floor.
• The CCU’s heat sink device must be located more than 3 cm (1.181 in) of any obstacle.
• Never unplug a cable while the Control Unit is turned on.
• Grounding must be done according to the regulations in effect to ensure the safety of the personnel.
• Do not use this marking equipment in an explosive environment.
This Control Unit is exclusively used to operate Technifor marking heads. If used for other purposes, Technifor
does not guarantee the quality of the results obtained. Technifor is not responsible for the damage the CCU may
cause in case of inappropriate use.
Technifor will not be held responsible for injuries resulting from disregard for the above operating instructions or
other general safety rules applicable to the use of this equipment. Furthermore, disregard for the instructions will
void the warranty.
The modification or transformation of this equipment, adaptation and accessory
installation unrecommended by Technifor, integration, piloting by a command device,
connection to an external peripheral, modify this equipment’s characteristics and
therefore void the compliance with the applicable EU directives. These modifications
void Technifor’s liability. In this case, the machine and equipment installer is
responsible for the final work station’s compliance.

 Description of the communication signals
• Start marking (Input)
- To activate the "Start marking" Input, establish a zero potential electrical connection between pins 4 and 5.
- This connection must not be inferior to 500 ms nor superior to the cycle time of the marking file.
• Stop marking (Input)
- To activate the "Stop marking" function, remove the electrical connection between pins 5 and 9.
• Marking in progress (dry contact Output)
- The information "Marking in progress" is available between pins 3 and 8. It is provided by a potential free "dry"
contact (relay contact).
- This signal indicates that the CCU is performing a marking.
• Machine ready (dry contact Output)
- The information "Machine ready" is available between pins 6 and 7. It is provided by a potential free "dry"
contact (relay contact).
- This signal indicates that the CCU has received all the instructions required to perform a marking.
Note
The 7 pin is common to the "Fault" information and to "Machine ready". See: Connection diagram for the dedi-
cated Inputs / Outputs
• Fault (dry contact Output)
- The information "Fault" is available between pins 2 and 7. It is provided by a potential free "dry" contact (relay
contact).
- This signal indicates that the CCU has a fault (either of power, or of CPU).

Remarks
• Pause:
Whatever the mode selected: when marking is interrupted, the "Marking ready" signal returns to phase 1. Other
signals are not modified.
•Fault:
Whatever the mode selected: if failure occurs (origin or EM machine temperature failures), the "Fault" signal goes
to phase 1. The other signals return to phase 0 until operator acknowledgement.
• In-process mode:
Launch a "Start cycle" Close the dry contact between pins 4 and 5.
Stop the cycle Open the dry contact (usually closed) between pins 9 and 5.

 Characteristics of the Inputs
8 opto-insulated Inputs are available and controllable by positive logic.
They are divided into 2 groups. Each group has its own negative reference (pins 6 and 19), and must be wired to
the desired potential.
It is possible to control the Inputs with the + 24 V internal voltage available on pins 1 and 14, and referenced Gnd
on pins 7-10-20-23.
Note
The + 24 V internal voltage (pins 1 and 14) is not protected from short-circuits.
The current delivered by the + 24 V voltage (pins 1 and 14) should not exceed 300 mA.
• consumption and operating range of the Inputs
- applicable voltage per Input: 12 V - 24 V
- intensity consumed per Input: approximately 5 mA
• wiring of 8 inputs with power supplied by UC500
In this case the Inputs are no longer opto-insulated.

 Characteristics of the Outputs
4 Outputs of the type NPN with open collector are available.
The maximum external power supply for the Outputs is 24 volts (continuous current).
The maximum current that can be commutated by an Output is 40 mA.
Remarks
• The + 24 V internal voltage (pins 1 and 14) is not protected from short-circuits.
• The current delivered by the + 24 V voltage (pins 1 and 14) should not exceed 300 mA.
The Outputs are not protected against polarity inversion and over current. When
connecting inductive charges use an anti-parasite protection and a free-wheel diode
to avoid damaging the Outputs.
