4.3. The outputs
The CamCon has, concerning each upgrading level, up to 32 outputs and with extreme extension (e.g.
CamCon DC16/IO, DAC16 or DC91/IO) up to 200 short circuit-proof outputs. They deliver 24Volt high
active signals and are not potentially free towards the CPU. The outputs 1 to 16, as well as 17 to 32 of
the unit have to be supplied with 24Volt , because the power supply of the outputs has been separated
in order to achieve a better power distribution.
4.3.1. The 40mA outputs (only CamCon device with aluminium back wall)
If all outputs are activated, not more than 40 mA permanent current in the complete temperature range
should be extracted per output, else the unit will deactivate with an error message. If a higher starting
performance is required, one has to know that the outputs are combined in 4 groups, each group
consisting of 8 outputs. Within each group, 480 mA permanent current at a surrounding temperature of
50°C, and at a surrounding temperature of 25°C even 700mA permanent current is available. This
permanent current can be dirtributed freely within a group, as long as the single output current of 300
mA is not overshot (see chapter "7.4.6.2. Setting the outputs" on page 63).
4.3.2. The 500mA outputs
At a surrounding temperature of 25°C even 500mA permanent current is available for each output. If
your outputs are overloaded or short-circuited the unit will deactivate with an
"out-err"
message
(see chapter "7.4.6.2. Setting the outputs" on page 63).
Attention:
For inductive loads the inductances have to be tripped with a freewheeling
diode.
4.4. The inputs
The CamCon has, concerning each upgrading level, up to 16 inputs and with extreme extension up to
200 inputs. These inputs work with high externally active 24Volt signals and are not potentially free
towards the CPU.
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 63, chapter "7.4.1. Measuring system" on page 45,
chapter "7.4.6.7. Setting the external program selection" on page 64 and chapter "7.4.6.4. Setting the
keyboard lock" on page 63.
4.5. 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.
