Configuring the analog output for temperature control
After you have set up the analog inputs for temperature, map them to the corresponding analog output. Use AO-3 for air supply.
Setting up the operating mode for temperature 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. Swipe left until you get to the analog input that corresponds to the analog output you want to make changes to.
4. On the
ANALOG
screen, tap
Output.
5. On the
Output
screen, tap
Operating Mode
and choose from the following options:
•
Direct
•
PID
6. To save the new settings, collapse
Output
.
Setting the output signal range for temperature control
If you select the 0-5V, 0-10V, 0-20mA range, the analog output swings from zero to the maximum specified by the hardware DIP switch
selection. If you select the 1-5V, 2-10V, 4-20mA, it includes an offset from zero.
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. Swipe left until you get to the analog input that corresponds to the analog output you want to make changes to.
4. On the
ANALOG
screen, tap
Output.
5. On the
Output
screen, tap
Range
and choose from the following options:
•
0-5V, 0-10V, 0-20mA
•
1-5V, 2-10V, 4-20mA

Selecting the corresponding analog input channel
Map the corresponding analog input channel to the analog output channel.
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. Swipe left until you get to the analog input that corresponds to the analog output you want to make changes to.
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
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.
2. To view analog input settings, tap
Analog I/O
.
3. Swipe left until you get to the analog input that corresponds to the analog output you want to make changes to.
4. On the
ANALOG
screen, tap
Output
.
5. To set an upper and lower limit, tap the Limit arrow.
6. Move the sliders towards the
Plus
icon to increase or towards the
Minus
icon to decrease the
Upper
and
Lower
Limit.
