Starting operation
• Fasten the temperature sensor to the solder bath using the clamp, so
that the sensor dips into the solder.
• Establish the power supply for the solder bath by means of the solder
bath power cable.
•
Insert the power cable of the control station into a ground contact
socket.
• Switch on the device (set mains switch to I).
•
The control station is now ready for operation.
After the display test has been run through (all display elements briefly light up simul
-
taneously) and the switch-on text (
����
) appears, the actual temperature determined
by the temperature sensor is displayed. The heating elements of the solder bath are
energized for heating the solder bath.
Note:
“
��
” appears in the LED display while the temperature determined by
the temperature sensor is near room temperature. The actual tempera-
ture is displayed when it exceeds room temperature.
If the control station ascertains after a monitoring period that the solder
bath or heating plate is not being heated, then the heater is switched
off and the error message “
����
” is displayed (see section 6.2 on Error
Messages).
4.3
Notes on changing the temperature sensor
The control station monitors the heating condition of the the connected device. While
the heating elements are being energized, the temperature must increase within a
certain monitoring period. If the control station ascertains after a monitoring period that
the solder bath or the heating plate is not being heated, then the heater is switched off
and the error message ”
����
” is displayed.
When installing the temperature sensor for the first time or replacing it, make sure that
the sensor is also heated through the solder bath housing, so as to suppress the error
message.
The monitoring of the heating can also be suppressed when starting operation or chang
-
ing the temperature sensor by using program 5 (see 5.1 on the Programs).
