Configuring humidity recovery delta (hysteresis):
The Humidity Recovery Delta command allows configuration of the percentage of change needed to recover from a
humidity alarm.
NOTE: After exceeding a low or high humidity threshold (thus entering an error condition), the humidity value must return past the
threshold by the configured recovery delta amount to clear the error condition. Default of humidity recovery delta is 2% relative humidity.
To configure the humidity recovery delta:
At the Switched CDU: prompt, type set trap ths humiddelta, followed by the sensor name, the percentage for the
recovery delta, and press Enter. Valid range is 0-20%.
Example
The following command configures the recovery delta at 2 relative humidity for temperature/humidity sensor .A1:
Switched CDU: set trap ths humiddelta temp_humid_sensor_A1 2
Enabling or disabling the humid trap:
The Set Trap THS Humid command is used to enable or disable the Humid trap.
To Enable or Disable the Humid trap:
At the Switched CDU: prompt, type set trap ths humid, followed by the sensor name and on or off. Press Enter.
Example
The following command enables the Humid trap for the first temperature-humidity sensor:
Switched CDU: set traps ths humid .a1 on
Setting the humidity sensor threshold limits:
The Set Trap THS Humidlow and Set Trap THS Humidhigh commands are used to set the lower and upper threshold
limits for the Humidity sensor.
To set the Humidity threshold limits:
At the Switched CDU: prompt, type set trap ths, humidlow or humidhigh, followed by the sensor name and a value
from 0 to 100 in percentage of relative humidity. Press Enter.
Example
The following command sets the first humidity sensor low threshold limit to 5:
Switched CDU: set trap ths humidlow .a1 5
