not change any setting unless you are familiar with their meaning. For more
information on these parameters, consult your system vendor or the fieldbus
specification.
Power Feed A/B voltage
Adjust the limits so that they correspond to the minimum and maximum output
voltage according to the datasheet of your bulk power supplies. Default operating
range is 19.2 V to 30 V.
Default
Low-low limit: 19.2 V
Low limit: 19.2 V
High limit: 30 V
High-high limit: 30 V
Minimum value
0 V
Maximum value
40 V
Alarm hysteresis (no alarm
→
alarm
→
no alarm) 0.5 V
1 V
Note that the limit values have to be in rising sequence at all times:
Low-low-limit
≤
low-limit < high-limit
≤
high-high-limit
and high limit must be at least 1 V higher than low limit.
Module temperature
The default values are limits for the F801 fieldbus power supply maximum operating
temperature of 65 °C. The user may reset this to the maximum operating temperature
of the power supply used or select a lower limit based on normal operating
temperature of the cabinet. Setting the limit at the lower of the maximum operating
temperature of the power supply or 10 °C above the normal operating temperature is
recommended.
