8.3 Temperature Supervision
The temperature supervision is necessary for protection in case of high power dissipation in failure cases, for example
short circuit of supply outputs.
In case of over temperature
•
•
In case of further temperature rising power consuming
blocks are switched off (shutoff phase):

PRODUCTION DATA - JUL 2, 2012
ELMOS Semiconductor AG
the warning signal OTEMP for the host controller is
generated
in Normal Mode a State.indication service is sent
to the host controller once at the beginning of over
temperature situation
no further transmission at KNX (KNX transmitter is
disabled) in both Analog and Normal Modes

When E981.03 temperature is lower than the limit:
•
•
•
V20 and VCC supplies are switched off
SAVE is activated
RESET is activated when VCC is lower than the reset
limit – not depending on temperature.
VCC and V20 supplies are switched on again
SAVE_N is deactivated
KNX transmitter is enabled
