• all shields should be one-side earthed or connected to the protection
wire, the nearest possible to the temperature limiter,
• as a rule of thumb, wires transmitting different signals should be spa-
ced as far as it is possible (at least 30 cm) and should be crossed only
at the right angle of 90°.

Powering on
When the power is turned on, the temperature limiter performs the display test, displays
rL10
, the program version, and then displays the set point.
The display may show a character message informing you of abnormalities, see table 9).
LED indicators
FAULT
-
(error indicator) Enabled when:
•
temperature limiter conditions are met, i.e. the temperature limit is
exceeded (see fig. 13) OR
•
a temperature sensor error (sensor short / open) will occur.
The algorithm to disable the error indicator (transition to normal operating
state) depends on the limitation maintaining function (
LJlt
).
When limitation maintaining is inactive (
LJlt = off
), FAULT
indicator is
disabled when:
•
temperature limiter conditions have ceased to exist, i.e. the
temperature limit is not exceeded (see fig. 13) AND
•
there is no temperature sensor error (sensor short / open); When the
limitation maintaining is active (
LJlt = on
) FAULT indicator
is deactivated when:
•
temperature limiter conditions have ceased to exist, i.e. the
temperature limit is not exceeded (see fig. 13) AND
•
there is no temperature sensor error (sensor short / open) AND
•
there has been reset of the limitation maintaining by simultaneous
pressing the
and
button for 2 sec.
The FAULT indicator takes the opposite state to the OUT indicator.
