Configuring analog inputs to measure pressure
To configure the FMS-2000C controller for pressure, you can use AI-1, AI-2, AI-3 and AI-4. Analog Input 1 can only be configured for
pressure and is pre-configured by the factory. If your FMS-2000C controller came with more than one pressure sensor, AI-2, AI-3 and
AI-4 are pre-configured for pressure accordingly. If you are using third-party pressure sensor you need to select pressure from the list of
input types.
Specifying the parameter type for pressure
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. On the
ANALOG 1
screen, swipe left to get to the analog input you want to configure.
4. Tap the
Type
arrow and choose
Pressure
.
5.
To confirm the settings, tap the
Checkmark
icon.
Specifying the sensor type
If you purchased a Johnson Controls pressure sensor, the sensor type comes pre-configured as
Remote Digital
. If you are providing
your own pressure sensor, the preset is
Third Party
.
If you are using a remote digital sensor, see
Specifying the sensor location
. If you are using a third party sensor, see
Specifying the minimum pressure input
for more information.

Specifying the maximum pressure input
To specify the maximum pressure input for third-party pressure sensors, 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 input you want to adjust, swipe left.
4. On the
ANALOG
screen, tap the
Maximum Pressure Input
arrow.
5.
Enter the maximum pressure input specific to the sensor you are using.
6.
To confirm the settings, tap the
Checkmark
icon.
Specifying the minimum pressure input
If the pressure sensor is bidirectional, the minimum pressure input is the negative limit of the differential range. If the sensor is
unidirectional, the value is zero. To specify the minimum pressure input for third-party pressure sensors, 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 input you want to adjust, swipe left.
4. On the
ANALOG
screen, tap the
Minimum Pressure Input
arrow.
5.
Enter the minimum pressure input specific to the sensor you are using.
6.
To confirm the new settings, tap the
Checkmark
icon.
