7.2 Switching on/off
Switching on
1. Ensure that the supply line of the supply voltage is connected.
Humidity within the product cabinet
If the product was subjected to an environment with
high humidity while switched off, it may be neces-
sary to reduce the humidity within the product cabi-
net. To do this, follow the instructions below before
switching on the product at the main switch.
2. Ensure that all protection covers of the product are firmly in-
stalled and, if present, all doors of the product are closed.
3. Ensure that the water cooling of the product is switched off first.
4. Switch on the product with the main switch.
5. Turn the key switch on the front side of the product to TEST or
ROBOT, depending on the application.
Determining the dew point temperature
The product is equipped with sensors that measure
the humidity inside the product and the cabinet tem-
perature. If the dew point temperature calculated
from the two parameters is too high, the product
outputs a corresponding alarm message (see Mes-
sages of the Dew Point tab).
6. If necessary, wait for some time until the installed dehumidifier
has lowered the dew point temperature to a temperature that is
below the temperature of the coldest laser module.
The current dew point measurement can be checked in the LaserNet software in
the Dew point tab (see section
Dew point tab [
}
104]
). The temperature of the
coldest laser module can be read from the
Status
tab (see section
Messages of
the Status tab [
}
145]
).
7. Ensure that the supply lines for water are connected to the prod-
uct.
8. Switch on the external laser chiller.
