1
WATER
：
The water pipe interface, inlet and outlet are connected to the inflow and
outflow of cooling water respectively, please connect this interface to the PU pipe of the
corresponding outer diameter size according to the laser model (see Table 5 for laser model and
corresponding water pipe size).
2
CDA
：
Clean and dry air connection for access to clean and dry air to prevent
condensation on the laser.
3
AC INPUT
：
The power input socket must be connected to the corresponding input
voltage according to the laser model (see Table 4 for laser model and corresponding input
voltage), and the matching plug provided by Roca must be used.
4
POWER
：
Air switch to control the on/off of AC power.
5
FIELDBUS
：
Bus interface (reserved).
6
ETHERNET
：
Ethernet interface. Provides remote control of the laser and storage of
alarm information.
7
CTRL-INTERFACE:
Control interface, CTRL-INTERFACE interface (24-pin),
multi-functional multiplex port, which allows the user to set the control mode, input the analogue
voltage signal, modulate the 24 V signal and is also the alarm signal output interface.
How to use the CDA
：
a) When using a CDA, the CDA should be dried and cooled by a chiller and filtered by a
5um and 0.3um particle filter and a 0.1um oil mist filter, respectively, at a temperature
in the range of 5-40°C, with a maximum dew point of 0°C (it is recommended that the
compressed air temperature be 5°C below the cooling water temperature), an air
pressure of less than 0.1 MPa, a flow rate setting of 10 LPM and a connection pipe
diameter of 6 mm.
b) When using CDA filter components supplied by Roca, the incoming compressed air is
to be dried and cooled by a chiller with an air pressure of less than 0.8 MPa and a
connection tube diameter of 6 mm.
c) Ventilation must be started 30 minutes before the start of the machine, but in winter,
when the temperature is below 10
°C
and the humidity is below 50%, ventilation may
not be used.
