Table 1. Humidification Proportional Steam Output Attributes

Name

Type 1

Description

Default Value

Compensator Humidity Cmd

 

Controls the humidifier valve. The valve is commanded from 0% to 100%. This output incorporates the Lead Compensator.

0.0

Display Units: %

Delay

 

Defines the time that the Humidity Percent Cmd is held at 0% following activation of the Isolation Valve Command.

300 Seconds

Discharge Humidity

 

Contains the process variable when the activity operates in the Limited H Control mode.

70.0% RH

Discharge Humidity Setpoint

 

Contains the desired process variable setpoint when the activity operates in the Limited H Control mode.

70.0% RH

Humidity Control Status

V

Contains the current saturation status of the controller.

Set Name: Control Status

Humidity Percent Cmd

V

Contains a representative analog percent output on a scale of 0% to 100%. This output should be connected to the humidification control device.

Display Units: %

Humidity Process ID

 

Defines the type of process being controlled. This input must be set to either zone humidity or return humidity depending on the actual process.
