Connecting The Fitting; Reading The Fitting Code With A Handheld Scanner - HURNER HCU 300 Manual De Instrucciones

fault, lower-case letters appear on the screen. To
enter upper-case letters, hold down the ñ key while
selecting the appropriate letter by one or several
keypresses.
The welding unit can be configured to ask for the weld-
er identification code before the fitting code is entered.
The display screen then shows the message "Enter Welder
Code." (Later this screen can be accessed by a quick access
routine; see Sect. 6.1.) The numeric code can be entered ei-
ther by reading it from a tag with the scanner or by using
the alphanumeric keypad. Whether the welder identifica-
tion code has to be entered and if so, when or how often,
is determined in the "Settings" sub-menu of the configura-
tion menu (see Sect. 10.1).
When the welder code is read from a bar code using the scan-
ner, 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 pressing the START/
SET key. If the code entered is not correct, a "Code Error"
message appears; check the sequence of numbers and cor-
rect as needed. If the code entered is correct, it is saved to
system memory and inserted into the welding reports to be
printed.
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.

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
lead to improper welding and also to overheated and fused
connection terminals. Protect the cable connectors against
getting dirty at all times. Terminals and push-on adapters
should be considered consumables and, therefore, have to
be checked before every welding operation and replaced if
damaged or dirty.
When the fitting is connected, instead of the "No Contact"
message (see Display 2) the number of the next welding re-
port appears, e.g., "Prot. No.: 0015."

Reading the Fitting Code with a Handheld Scanner

Only the bar code on the tag sticking on the fitting to be
welded may be used. It is not acceptable to read the fitting
code tag of a fitting of a different kind if the intended one
is damaged or unreadable.
