7.15.10.3 Object 0x2805: PCB temperature
This parameter contains the temperature (in °C) of the servo valve electronics. A fault is generated if the pa-
rameter value is below or exceeds the following temperature values:
PCB temperature < –20 °C
PCB temperature > 85 °C
PCB temperature > 105 °C
Fault description
7.15.10.4 Object 0x2809: Maximal PCB temperature
This parameter shows the maximal reached temperature of the PCB. The customer is able to reset the value.
Regardless of which value is written to this parameter, the value is set to 0. The valve will automatically in-
crease this parameter to the actual maximum temperature.
7.15.10.5 Object 0x280D: Operating time
The parameter <PowerOnTime> (0x280D) contains the power on time (in minutes) since production of the
servo valve.
The parameter <OperatingTime> (0x280D) contains the time (in minutes) the servo valve is in the device
state machine (DSM) states 'HOLD', 'FAULT HOLD' or 'ACTIVE'.

Table 99: Fault codes
The PCB temperature should not exceed the range of –20…85 °C to ensure proper operation.
The electronics temperature has a big impact on the electronics lifetime. The longest service life is
achieved when the higher temperatures are avoided.
