MALFUNCTION
smart Stove - 0142 - 42WMSUGAT2-C
73
Malfunction
The differential temperature controller smart Stove indicates faults.
Sensor monitoring
The temperature sensors TS1 to TS6 are monitored for short-circuit or interruption. A sensor fault
(interruption or short-circuit) is indicated in the model diagram by three minus signs: “---”.
The controller has stored temperature limits which comprise the temperature range that is usually to
be expected for a heating control. If this range is left, the controller signals an error.
In case of use of PT1000 sensors, the following limits have been established:
• Short-circuit: Measured temperature ‹ -30°C (resistance ‹882
)
• Interruption: Measured temperature › 250 °C (resistance ›1.931
)
The “Attention” symbol appears at the top right corner of the
display.
A symbol indicates that there is a fault and the controller is in
failure operation.
To start the ›Service Wizard‹, press the knob.
NOTICE
If a malfunction message appears in the display, the operator
can define the possible causes by means of the ›Service
Wizard‹ so that he/she can provide the installer with precise
information.
There may be various deficiencies in a thermal system, which
require a wide variety of approaches. The controller communi-
cates every step to the operator or installer via the screen, so
that there is no need to describe all malfunctions in detail in
this operating manual.
DANGER
Repair or disassembly
Lethal danger due to electrocution!
For troubleshooting on the plant, disconnect all poles of the
power supply reliably and protect it them against being
switched on again!
