With a cooling defect (fan defective, ambient temperature too high), as well as a
critical error, an error message is generated by the S-IPC: T
o
Cancel error messages:
o
The alarm can be delayed for any amount of time by entering the desired
value in the "Suppress alarms for the next [] seconds" field.
o
Set alarm parameters:
o
The PWM stage ("Desired Fan Speed") can be set between 0 and 15,
and indicates the fan speed from 0% to 100%.
o
Starting from a PWM stage of (default value) 10, the fan speed is ana-
lyzed and an alarm message generated when one or both fans malfunc-
tion.
o
With the
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SIPC\
Parameters\FanBlockedDetectionThreshold" registry key
the fan speed monitor can be defined:
Values < 5 are impractical, since the fan typically starts with
PWM stage of 2 .. 3.
A value > 15 means that no fan warning is generated, since the
highest PWM stage is 15.
The default value after the drive installation is 10.
o
Activate and deactivate alarms:
With the deactivation of alarms, the application must assume (thermal) monitoring to
avoid damage to the module!
Si les alarmes sont désactivées alors l'application doit prendre en charge la surveil-
lance afin d'éviter des dommages (thermique) de l'appareil!
