5.1 Turning the Welding Unit on

After connecting the power supply cable to mains power
or a generator, turn the welding unit on using the On/Off
switch. This causes Display 1 to show.
Then the screen changes to Display 2. While it is showing,
the welder is ready for the connection of the electrofu-
sion fitting.
CAUTION in case of System Errors!
If during the auto-test that the unit performs at
start-up, an error is detected, a "System Error" mes-
Caution
sage shows on the display. When this happens, the
welding unit has to be disconnected immediately
from the power suppy and the fitting, and it has
to be shipped to the manufacturer for repair.

5.2 Entering the Welder ID Code

The welding unit can be configured to ask for the welder
identification code before the fitting code is entered. The
display screen then shows the appropriate message. (Later
this screen can be accessed by a quick access routine; see
Sect. 6.1.) The numeric code can be entered either by read-
ing it from a tag with the scanner or by pressing the ï, ð,
ñ, ò cursor keys. Whether the welder identification code
has to be entered and if so, when or how often, is deter-
mined in the "Settings" sub-menu of the configuration
menu (see Sect. 10.1).
When the welder code is read from a bar code using the
scanner, an audible signal confirms this and the screen
shows the read code and switches to the next input display.
When the code is entered manually, it is saved by press-
ing the START/SET key. If the code entered is not correct,
a "Code Error" message appears; check the sequence of
numbers and correct as needed. If the code entered is cor-
rect, it is saved to system memory and inserted into the
welding reports to be downloaded.
Only an ISO standard-compliant welder identification code
is accepted by the unit. If the welder code feature is dis-
abled, the input screen for the welder code will not show.

5.3 Connecting the Fitting

Connect the connection terminals to the fitting and check
for proper contact. Use terminal adapters if needed. The
contact surfaces of the cable connection terminals or adapt-
ers and the fitting have to be clean. Dirty terminals may
