Naming the air flow input
Set up a name for the analog input you want to appear on the home screen. If your FMS-2000C controller is in portrait mode, you can
have up to 16 characters. If your FMS-2000C controller is in landscape mode, you can have 12 characters.
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 input you want to set up a new name for, swipe left.
4.
On the ANALOG screen, scroll down and tap the Name arrow.
5.
On the Name screen enter a new name.
6.
To confirm the new name, tap the Checkmark icon.
Configuring the analog inputs for volumetric offset control
Use volumetric offset control (VOC) when you want to maintain an offset setpoint between the total supply and total exhaust air flows
including any fume hoods in the monitored space. To configure for volumeteric offset control, configure both AI-3 and AI-4 for air flow.
Use AI-3 and AI-4 for total supply and total exhaust air flows respectively.
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 configure AI-3 for flow, swipe left twice.
4.
On the ANALOG 3 screen, tap the Type arrow.
5.
On the Type screen, scroll to Flow and tap the Checkmark icon to confirm the new settings. Refer to Configuring the analog input
to measure air flow to complete the setup of AI-3.
6.
To configure AI-4 for flow, swipe left three times.
7.
On the ANALOG 4 screen, tap the Type arrow.
On the Type screen, scroll to Flow and tap the Checkmark icon to confirm the new settings. The volumetric offset switch appears
8.
on the ANALOG 4 screen. Refer to Configuring the analog input to measure air flow to complete the setup of AI-4.
9.
Switch volumetric offset on.
10. See Configuring the analog input to measure air flow to complete your setup for Volumetric Offset.
Configuring the analog output for air flow control
If you are controlling flow, map the analog input to the corresponding analog output as required by the specific application. Refer to the
submittal package wiring diagrams to map the analog output correctly.
If you are controlling volumetric offset, map AI-3 and AI-4 to the corresponding analog outputs as required by the specific application.
To map the analog output, refer to the submittal package wiring diagrams. Use AO-3 for the supply valves and AO-4 for the general
exhaust.
Changing the operating mode for air flow 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.
To change the operating mode, expand Operating Mode arrow and tap Direct Analog or PID Analog.
5.
6.
Collapse Operating Mode to save the new settings.
