4.4. The outputs

The CamCon 16 has 8 or 16 short circuit-proof outputs. They supply 24V high active signals and are
not free of electrical potentials. The output voltage runs thus with the supply voltage of the device. The
outputs of the device are supplied with 24V by pins 10 and 29 and with 0V by pin 1. Outputs 1 - 8
supply a permanent current of 0.5Amp. per output. The outputs 9 - 16 even supply a permanent
current of 40mA per output (see also chapter "7.4.6.2. Setting the outputs" on page 62).

Please note:

Outputs 13 - 16 share the pins with the inputs 5 - 8.

Attention:

For inductive loads the inductances have to be tripped with a freewheeling

diode.

4.5. The inputs

The CamCon has 8 inputs. These input work with high active 24V signals and are not free of electrical
potentials.

Please note:

The inputs 5 - 8 share the pins with outputs 13 - 16.

The input wiring:

The input resistance
is about 5.7 KOhm.

The inputs of the CamCon have not been covered with functions by the factory. The user would have
to do this himself in the process of setting system data of the CamCon depending on his requirements.
See chapter "7.4.6. System upgrading" on page 62, chapter "7.4.1. Measuring system" on page 44,
chapter "7.4.6.7. Setting the external program selection" on page 63 and chapter "7.4.6.4. Setting the
keyboard lock" on page 62.

4.6. Precautionary measures for welding work

Attention:

For the duration of welding operations carried out at the machine, the
connecting wires concerning the data exchange from the measuring system to
the CamCon and the power supply as well as the grounding connections and
inputs and outputs have to be separated from the CamCon.

4.7. The status LED

The status LED of the CamCon shows the different blinking intervalls of the the device state. This way,
the operation state of the device can be seen without a PC or a terminal.

total time:

3.2 seconds

State

= "OK"
= "Clear..."
= "Pos.Error: 1"
= "Pos.Error: 2"
= "Pos.Error: 3"
= "Pos.Error: 5"
= "Output Error"
= "indicates an error in the EEPROM memory"

See also chapter "9. Error messages and removal of errors (FAQ)" on page 78.
