IndraControl L40
Technical Data
4-3
DOK-CONTRL-IC*L40*****-PR03-EN-P
DANGER
Danger of destruction by overheating
⇒
Ensure a surrounding air temperature of less than
45
°
C.
⇒
If surrounding air temperatures range from 45
°
C to
55
°
C, the optionally available blower has to be used.
An integrated blower control with hysteresis activates
the blower if a critical internal temperature is
reached; once the temperature falls below uncritical
values, the control deactivates the blower again.
⇒
If the temperature reaches a value of 75
°
C, the
control is automatically entering a standby mode so
that damage is prevented. The outputs enter the safe
status, and the warning "Temp !!!" appears on the
display.
This mode can only be quit by switching the power
supply off/on.
⇒
By means of a lib function, the application program
can read the internal temperature of the
IndraControl L40, in order to trigger further reactions.
Refraining from a blower may be considered if all of the following
conditions are fulfilled:
•
Surrounding air temperature < 45
°
C
•
Load applied to the 7.5-V Inline supply (U
L
) < 1 A
•
Load caused by the onboard outputs < 1 A
•
Load caused by the function modules < 10 W (see fig. 7-27)

Note:
The IndraControl L40 as well as the additionally available
function modules correspond to the CE requirements!
Note:
Systems with IndraControl L40 components, that are used in
residential areas (housing, business and commercial areas as
well as small-sized enterprises), require a single approval by
an authority or a testing agency. In Germany, such single
approvals are issued by the "Regulierungsbeh
