if it is clear by other means that the pipe-fitting joint which is still warm
is not subjected to an external force. This is not recommended, though,
because the system will assess as faulty a joint with canceled cooling.
While the joint might still be in order, its documentation will not.
Important
In a welding operation with inside balloon, the cooling time
must never be cancelled/aborted
. The new joint cools down
with full pressure inside the balloon. If the pressure were
released too soon, an unwanted bead would form inside the
components. Therefore, the welder can switch the system back
to the enter-bar-code screen (Display 3) only when the cooling
time has been waited out. To switch back, press START/SET
or STOP/RESET-Taste (which exceptionally are equivalent in
this case). This signifies the proper conclusion of the welding
process, and, therefore, only now the screen asks whether the
pressure in the balloon should be released. Answer this ques-
tion by pressing START/SET.
4.7 Aborted Welding Process
All welding-relevant data are constantly monitored while the welding
process is running. If one or more of the parameters are out of tolerance
and the machine cannot adjust them, the welding process is aborted after
a given period of time.
The error that made the welding abort is displayed on the screen (see
Display 13).
Info
If one or more errors occurs rather frequently, contact customer
service. It may be possible to correct the error on site without
further trouble, or at least to identify its cause.
Type of Error
Description
a. Data Input
Input Error
Error while entering data with the alphanumeric and cursor keys.
Code Error
Error while reading data from a bar code or an RFID card.
b. System and Conditions
System Error
The welding system has to be disconnected immediately from both the
power supply and the electrofusion fitting. The auto-test has detected
an error in the system. The welder must no longer be operated and
has to be sent to an approved shop for check and repair.
Clock Error
The internal clock of the machine is defective; re-set the clock in the
Configuration Menu.
Unit to Service
The recommended next service date for the welder is overdue. The
service due message has to be acknowledged by pressing the START/
SET key. Send the welding system to the manufacturer or an
approved service point for service and check-up.
Power Supply Failure at Last
Welding
The last welding is incomplete. The welding unit was disconnected
from the power supply voltage while it was in progress. To go on using
the unit, this error has to be acknowledged by pressing the STOP/
RESET key.
Ambient Temperature high
Outside temperature outside the range from – 10°C to + 45°C.
Ambient Temperature low
Outside temperature outside the range from – 10°C to + 45°C.
Insufficient Voltage
The input voltage to the control unit is < 185 V; the welding process, if
started, will likely be flawed and should not be started or repeated if
the error appears during welding..
Excessive Voltage
The input voltage to the control unit is > 280 V; the welding process, if
started, will likely be flawed and should not be started or repeated if
the error appears during welding.
