Description
[ ]V Pwr supply voltage is low
Possible Cause
•
For BPPB-based I/O packs, input voltage has dropped below 26.5 V. Input voltage is required to be within the range 28 V
±5%.
•
For BPPC-based I/O packs, input voltage has dropped below 24 V. Input voltage is required to be within the range 24 V
±10%.
Note
In most cases, normal pack operation continues below this voltage, but field devices that require 24 V from the
terminal board may begin to experience reduced voltage operation with undetermined results.
Solution
•
If PPDA is available to monitor control cabinet power check the I/O pack or module for active alarms.
•
Check I/O pack or module power within the control cabinet; begin with power supplies and working toward the affected
I/O pack or module.

Description
Temperature [ ] °F is out of range ([ ] to [ ] °F)
Possible Cause
•
Temperature went outside -35°C to 66°C (-31 to 151 °F) limits for PCNO or PPRF.
•
Temperature went outside -40°C to 90°C (-40 to 194 °F) limits for Mark VIe BPPC-based I/O modules.
•
Temperature went outside -35°C to 85°C (-31 to 185 °F) limits for BPPB-based I/O modules, and for Mark VIeS Safety
I/O modules.
Solution
Check the environmental controls for the cabinet containing the I/O pack. The I/O pack does continue to operate
beyond these temperature limits, but long-term operation at elevated temperatures may reduce equipment life.
