Performing a Programming Key Memory Erase
If an application is loaded on the Programming Key, and you want to
use a different application, you have to erase the Programming Key
memory.
The Programming Key memory is erased automatically when you use
FX Loader. However, when an application is loaded from a computer,
or when the application is loaded from another FX15 controller, you
must manually perform erase the Programming Key memory.
To erase the Programming Key memory:
1. Power up the Programming Key, either by hot-plugging it to an
FX15 controller (already on) or with an AC/DC adapter.
2. Press the Programming Key button for 15 seconds to initiate the
memory erase.
During the memory erase, the green Light-Emitting Diode (LED)
blinks slowly. Then the green and the yellow LEDs blink twice
alternately, and then the green LED remains on indicating the
memory is erased.
If the green and the yellow LEDs blink simultaneously, it means that the
erase process has failed. Retry. When the memory is completely erased,
the LEDs stop blinking. The Programming Key is now ready for a new
upload. The memory erase is also necessary if the previous upload from
the FX15 controller fails (communication has been interrupted).
Error Codes
You can view the error codes only when an integrated MUI display

Figure 31: Analog Input Jumpers
The active sensor (voltage or current) inputs have programmable range
parameters within the application software. These parameters,
HighRange and LowRange, define the equivalent values for reading at
High (10 V and 20 mA) and Low (0 V, 4 mA, and 0 mA) signal input.
Voltage and current inputs from differential pressure transducers can be
linearized by a square root function (SQRT), which operates over the
complete range of the input.
The passive sensors (resistance) have preprogrammed linearization
curves within the application software. For these sensors, the
measurement range is fixed. You can set the reliability range via
software.
The read signal is converted by the FX15 controller according to the
related Analog Input object setup. Available setups are:
• Linear 0-10 V
• SQRT 0-10 V
• Linear 0-10 V, 20% suppression (2-10 V)
• Linear 0-2 V
• SQRT 0-2 V
• Linear 0-2 V, 20% suppression (0.4-2 V)
• Linear 0-20 mA
• SQRT 0-20 mA

• Ni1000 Landis and Gyr®
• Ni1000 DIN
• Pt1000
• Ratiometric
The measurement unit is also configurable, enabling the controller to
propagate the measured value according to the appropriate scale unit via
the network. Available configurable units are:
• Temperature
• Percentage
• Air Pressure
• Liquid Pressure
• Flow
• Concentration
• Ampere
• Voltage
A configurable filter constant in seconds is performed by the FX15
controller on its Analog Inputs for the reduction of signal instability.
You can configure an additional Anti-Spike filter to limit the rate of
change of the input values to the value indicated by this attribute.
The FX15 controller provides a configurable jumper for (Terminal 13)
+5 V Analog Voltage Power Supply (AVPS), or a +16 V External VDC
supply, for active analog input sensors (see Jumper Details.)
The EXT VDC can supply up to 80 mA for a maximum of four 0/4-20
mA active sensors. The AVPS can supply up to 10 mA for ratiometric
sensors.
Connecting Active 0-10 V Sensors
The FX15 controller can accept all the active temperature, pressure,
flow, and humidity sensors providing 0-10 VDC signals.

Connecting Active Current Sensors
The FX15 controller analog inputs can accept a maximum of four active
current sensors, powered by the FX15 controller itself, in the range 0-20
mA or 4-20 mA. The AI has to be configured via software (and
hardware jumpers) to accept current signals. If a 4-20 mA sensor is
connected, the specific hardware jumpers must be closed
(see Figure 31) and the application can be configured through the FX
Builder, setting 0-20 mA, 20% suppression.
The FX15 controller can be connected to the P299xAx Series of

Connecting Active Sensors Powered by 24 VAC
The FX15 can accept active temperature, pressure, flow, and humidity
sensors providing 0-10 V or current signals powered by 24 VAC.
A second transformer (24 VAC/24 VAC, 3 VA maximum) powering
only the Analog Input is required to maintain the insulation from the
microprocessor.

Digital Inputs
The FX15 controller features eight opto-isolated digital inputs from
potential-free contacts. A digital input is active depending on its polarity
setting. The default setting is Direct, meaning it is active (true) when
closed.
See I/O Technical Details for the complete FX15 controller I/O table.
Digital Inputs Powered by 24 VAC
The eight FX15 controller Digital Inputs must be 24 V powered
(through terminals 34 and 35). Both AC or DC voltage can be used. If
DC is used, then the power supply of the DIs must be independent from
the controller power supply (FX15 controller is compatible with VAC
power only). The digital inputs can use the same FX15 controller
voltage supply, or they can be separately powered in order to maintain
the microprocessor opto-isolation from the controller voltage supply.

Using Analog Inputs as Digital Inputs
If you need more than 8 digital inputs, the FX15 controller allows you
to use an analog input as a digital input.
FX15
Figure 37: Digital Input Connection Diagram
The Analog Input needs to be properly configured in FX Tools to read
the digital input.
Analog Outputs
The FX15 controller provides up to four, 0-10 VDC, 1.5 mA maximum,
opto-isolated analog outputs. The Analog Output objects provide the
interface between the four hardware Analog Output channels and the
control application. See I/O Technical Details for the complete FX15
controller I/O table.
Use the application software to configure the analog outputs for direct
acting or reverse acting.
Use the high limit (MaxOutput) and low limit (MinOutput) values to
limit the output signal.
Powering and Connecting the Analog Outputs
Power the analog outputs separately, through Terminals 79 and 80, to
ensure microprocessor isolation from the controller power supply
(see Figure 39).
38 FX15 Controller Technical Bulletin
The FX15 controller analog outputs are commonly used to drive
proportional devices and can be connected to all the Johnson Controls
Proportional Valve Actuators (Figure 38).

Digital Outputs
The FX15 controller features nine digital outputs, available in two
hardware configurations: all nine relays, or four relays and five triacs.
Use the application software to configure the Digital Outputs for direct
acting or reverse acting.
! WARNING: Risk of Electric Shock. Disconnect or isolate all power
supplies before making electrical connections. More than one disconnect or
isolation may be required to completely de-energize equipment. Contact with
components carrying hazardous voltage can cause electric shock and may
result in severe personal injury or death.
AVERTISSEMENT: Risque de décharge électrique. Débrancher ou isoler
toute alimentation avant de réaliser un branchement électrique. Plusieurs
isolations et débranchements sont peut-être nécessaires pour-couper
entièrement l'alimentation de l'équipement. Tout contact avec des composants
conducteurs de tensions dangereuses risque d'entraîner une décharge
électrique et de provoquer des blessures graves, voire mortelles.

Connecting the Relays
The FX15 controller features up to nine Digital Outputs with
electromechanical relays. To simplify assembly, the common terminals
of some relays have been grouped together. The relays are divided into
six groups, according to the distance of insulation.
