ctive control place is visible: keypad, I/O or
fieldbus.
NUMERIC INDICATIONS
Provide information on values and location in the
menu structure.
UNIT
Unit of the value on screen visible.
READY
Lights up when AC power is on. In case of a fault,
the symbol will not light up.
DIRECTION

1 Run the Start Up Wizard
Note: Running the Start Up Wizard resets all parameters to their default values.
•Hold STOP button down for 5 seconds
•Select application type FAN or PUMP and confirm with ENTER
•Select motor nominal speed and confirm with ENTER
•Select motor nominal current and confirm with ENTER
•For speed signal 0 – 10 V use AI1 (Analogue Input 1)
2 Control Signal Settings for Speed Signals other than 0 – 10 V
•For other selections full parameter view is needed:
P2.1.14 Parameter Conceal Set to 0 (not in use)
•For speed signal 2 – 10 V use Analogue Input 1
P2.2.6 AI1 Signal Range Set to 4 (2 – 10 V)
•For speed signal 4 – 20 mA use Analogue Input 2
P2.1.15.14 I/O Reference Set to 1 (AI2)
•For speed signal 0 – 20 mA use Analogue Input 2
P2.1.15.14 I/O Reference Set to 1 (AI2)
P2.2.12 AI2 Signal Range Set to 1 (0 – 20 mA)

•Select motor nominal current and confirm with ENTER
4 Full view of parameters
•P2.1.14 Parameter Conceal Set to 0 (not in use)
5 Control Signal Settings
•For Volt sensor signal use Analogue Input 1 (AI1)
0 – 10 V Default (no settings needed)
2 – 10 V P2.2.6 AI1 signal range Set to 4
•For milliamp sensor signal use Analogue Input 2 (AI2)
4 – 20 mA Default (no settings needed)
0 – 20 mA P2.2.12 AI2 signal range Set to 1
6 PID
•PID settings
P2.9.1 PID activation Set to 1 (activate)
P2.9.2 PID reference
no external reference Set to 2 (value from keypad)
external reference Set to 0 (AI1) or 1 (AI2)
•Where is the sensor connected?
P2.9.3 Actual value input Set to 0 (AI1) or 1 (AI2)
•PID reference (set-point)
Note: Only apply if not using external reference from controller!
P3.5 PID reference value (Set point value in percentage)
% = ((set-point – minimum) / span) x 100
For example: set-point is 3.2 bar, the sensor span is 0 – 5 bar.
3.2 divided by 5 is 0.64; the value to set in P3.5 is thus 64
Note:Only one function per input. If there is a need to change mA input to V input or
vice versa, please see instructions in the NXL HVAC User’s Manual. Available for
download at http://inettrack.europe.honeywell.com/support.
