Configuring the analog output for humidity control
After you have set up an analog input to measure humidity, map it to an available analog output. The control output can be used to
modulate an actuator for either a humidifier, steam source, or a dehumidifier.
Changing the operating mode for humidity control
Each of the four analog outputs of the FMS-2000C controller can be configured for the following operating modes:
•
Direct operating mode
•
PID operating mode
In direct operating mode, the output tracks the mapped analog input directly or inversely. The PID operating mode may or may not
employ the proportional-integral-derivative scheme for closed-loop control of the analog output. The range of the output can or cannot
include an offset. This is independent of the mode the analog output is configured to.
To change the operating mode, complete the following steps:
1.
On the home screen, tap the Settings icon to enter the Settings menu.
2.
To view analog input settings, tap Analog I/O.
3.
To find the analog output you want to change the operating mode for, swipe left.
4.
On the ANALOG screen, tap Output.
5.
To change the operating mode, expand Operating Mode arrow and tap Direct Analog or PID Analog.
6.
Collapse Operating Mode to save the new settings.
Setting the input signal range for humidity
On the home screen, tap the Settings icon to enter the Settings menu.
1.
2.
To view analog input settings, tap Analog I/O.
3.
To find the analog output you want to adjust, swipe left.
4.
On the ANALOG screen, tap Output.
On the Output screen, expand Range and choose from the following:
5.
•
0-5V, 0-10V, 0-20mA
1-5V, 2-10V, 4-20mA
•
6.
To save the new settings, collapse Range.
Specifying the action mode for humidity
1.
On the home screen, tap the Settings icon to enter the Settings menu.
2.
To view analog input settings, tap Analog I/O.
3.
To find the analog output you want to change the action mode for, swipe left.
4.
On the ANALOG screen, tap Output.
5.
To specify the action mode, tap the Action Mode arrow and tap Direct or Reverse.
6.
Collapse Action Mode to save the new settings.
Selecting the corresponding analog input channel for humidity
Map the corresponding analog input channel to the analog output channel.
On the home screen, tap the Settings icon to enter the Settings menu.
1.
2.
To view analog input settings, tap Analog I/O.
3.
To find the analog output you want to change the analog input channel for, swipe left.
4.
On the ANALOG screen, tap Output.
5.
To select a corresponding analog input channel for this analog output, tap the Input Channel arrow.
6.
Scroll to the corresponding analog input channel and tap the Checkmark icon to confirm your settings.
Setting up limits for humidity
Limits prevent the analog output from going beyond a predetermined voltage or current output. You can specify the minimum and
maximum limits for the analog output in percentage. The default minimum is zero and the default maximum is 100%.
1.
On the home screen, tap the Settings icon to enter the Settings menu.
To view analog input settings, tap Analog I/O.
2.
3.
To find the analog output you want to change the limit for, swipe left.
On the ANALOG screen, tap Output.
4.
5.
To set an upper and lower limit, tap the Limit arrow.
Move the sliders towards the Plus icon to increase or towards the Minus icon to decrease the Upper and Lower Limit.
6.
7.
To confirm the new settings, tap the Checkmark icon.
