Acknowledge:
NONE
Cause:
For chassis power units, the following applies:
The alarm threshold for the air intake overtemperature has been reached. For air-cooled power units, the threshold is 42
°C (hysteresis 2 K). The response is set using p0290.
If the air intake temperature increases by an additional 13 K, then fault F30035 is output.
Remedy:
Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
A05003 (N)

Power unit: Internal overtemperature

Reaction:
NONE
Acknowledge:
NONE
Cause:
For chassis power units, the following applies:
The alarm threshold for internal overtemperature has been reached.
If the temperature inside the power unit increases by an additional 5 K, then fault F30036 is triggered.
Remedy:
Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
A05004 (N)

Power unit: Rectifier overtemperature

Reaction:
NONE
Acknowledge:
NONE
Cause:
The alarm threshold for the overtemperature of the rectifier has been reached. The response is set using p0290.
If the temperature of the rectifier increases by an additional 5 K, then fault F30037 is triggered.
Remedy:
Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the fan failed? Check the direction of rotation.
- has a phase of the line supply failed?
- is an arm of the supply (incoming) rectifier defective?
A05006 (N)

Power unit: Overtemperature thermal model

Reaction:
NONE
Acknowledge:
NONE
Cause:
The temperature difference between the chip and heat sink has exceeded the permissible limit value (blocksize power
units only).
Depending on p0290, an appropriate overload response is initiated.
See also: r0037 (Power unit temperatures)
Remedy:
Not necessary.
The alarm disappears automatically once the limit value is undershot.
Note:
If the alarm does not disappear automatically and the temperature continues to rise, this can result in fault F30024.

A05065 (F, N) Voltage measured values not plausible

Reaction:
NONE
Acknowledge:
