Installation and Operations Manual
Load Trap
The Load trap is generated whenever the total input load on an infeed exceeds a preset threshold. Load
traps include the reported input load, load status, Location of the PT22, and identifier/name of the
affected infeed. Any error state generates a Load trap and triggers the trap timer. A new trap is
generated at the end of every timer period until the Load returns to a non-error status.
Load traps
Status Error Description
Normal Infeed is on and within preset thresholds
NotOn Infeed is off
Reading Non-error state – Load status currently being read
LoadHigh x Infeed current load exceeds preset threshold
OverLoad x Infeed current load exceeds the measurable range for the infeed
ReadError x Unable to read Load status
NoComm x Communication to the infeed has been lost
Temp Trap
The Temp trap is generated whenever the temperature on a temperature/humidity sensor is beyond
preset thresholds. Temp traps include the reported temperature, temp status, location of the PT22, and
identifier/name of the affected sensor. Any error state generates a Temp trap and triggers the trap timer.
A new trap is generated at the end of every timer period until the Temp returns to a non-error status.
Temp traps
Status Error Description
Normal The sensor is working correctly and the temperature is within preset thresholds
NotFound No sensor has been detected
Reading Temp status currently being read
TempLow x Temperature at the sensor below preset low threshold
TempHigh x Temperature at the sensor exceeds preset high threshold
ReadError x Unable to read Temp status
Lost x Sensor initially detected but communication to the sensor has been lost
NoComm x Communication to the sensor has been lost
Humidity Trap
The Humidity trap is generated whenever the humidity on a temperature/humidity sensor is beyond
preset thresholds. Humidity traps include the reported relative humidity, humidity status, location of
the PT22, and identifier/name of the affected sensor. Any error state generates a Humidity trap and
triggers the trap timer. A new trap is generated at the end of every timer period until the Humidity
returns to a non-error status.
