6.1 Faults and Warnings
Faults and warnings are indicated by displaying the according fault and warning codes. Addi-
tionally faults are displayed by the red blinking of the “Enter’ button.
With the BACK you reach the main window 001. If the fault/warning is still active it will be
displayed by a blinking symbol in the status line of the screen. With the arrow key you
can reach the fault/warning code from the main screen. A fault/warning is displayed until the
according value reaches a normal state. Faults and warnings can be indicated by an optional
digital output module.
NOTICE
For internal or not assignable faults download a dataset using the LSB Remote Software and
sent it to LAMTEC for fault diagnostics.

Probe heating fault
/1 The heater is short-circuited or has a high resistance; tolerance time of
10 s
Help:
- Check the wiring.
LT3 Term. 13 and 14 disconnect the probe - probe heating at LT3 or in
SAK
and measure the heater resistance between wire pos. 13 and 14
on the probe side.
Resistance approx. 9 ... 10 in heated state.
- If not OK, exchange the probe and restart.
- If OK, the fault presumably lies on the main board of LT3.
If the lines of the probe heating and probe signal are mixed up
during connection (possible in the case of the SAK wiring), the mother
board is destroyed. Disconnect the probe and measure the heating
voltage: approx. 11V
/2 Heating power more than 15 s outside of the permitted range
(8W … 25 W)
