Required basic pump wiring

For basic FlexVander operation, connect supply, pump relay outputs, and operating-status feedback for each installed pump. Select the wiring table that matches the FlexVander program used on the installation.

Supply voltage

Supply	Terminal	Use	Note
100-260 VAC	N	Neutral	VAC and VDC supply can be connected at the same time.
	P	Phase
	Pm	Protective earth
8-36 VDC	DCIN	Plus
8-36 VDC	XGND	Minus

Program 1 basic wiring: one or two pressure pumps

Program 1 controls one or two pressure pumps without a submersible pump. Required for basic operation: start and stop relay outputs and operating-status feedback for each installed pressure pump.

Relay outputs

The relay outputs send pulses to the pump start and stop circuits. The output is not held active while the pump runs; pump running must be maintained by the pump control circuit, contactor, or holding circuit. Pulse time is configured with FVADOUTT#.

Relay outputs are normally-open contact sets. Maximum relay load is 5 A @ 250 VAC / 30 VDC. There are no internal connections to the relay outputs; wire the switched source through the listed terminal pair.

Output	Function	Terminals	Condition
Output 1	Start pressure pump 1	R1A-R1B	Required
Output 2	Start pressure pump 2	R2A-R2B	If pressure pump 2 is installed
Output 3	Stop pressure pump 1	R3A-R3B	Required
Output 4	Stop pressure pump 2	R4A-R4B	If pressure pump 2 is installed

Stop outputs can be changed to NC behavior with DWCONTACT# when the installation requires it.

Required operating-status feedback

FlexVander expects a feedback signal from each pump that has been started. If feedback is not detected after start, FlexVander stops the pump because it would otherwise run unmonitored. During operation, the same feedback input is used to detect that the pump has stopped.

With the Viking default JPDI1-JPDI4 = Position S, connect each pump-running contact across the listed terminals. The signal must be active when the pump is running.

Input	Pump	Terminals	Signal	Condition
Input 2	Pressure pump 1	DI2-GND	S0/NPNNPN is a negative signal (minus).; JPDI2 = S.	Required
Input 3	Pressure pump 2	DI3-GND	S0/NPNNPN is a negative signal (minus).; JPDI3 = S.	If pressure pump 2 is installed

Program 2 basic wiring: submersible pump and one or two pressure pumps

Program 2 controls one submersible pump and one or two pressure pumps. Required for basic operation: start and stop relay outputs and operating-status feedback for each installed pump.

Relay outputs

Output	Function	Terminals	Condition
Output 1	Start submersible pump	R1A-R1B	Required
Output 2	Start pressure pump 1	R2A-R2B	Required
Output 3	Start pressure pump 2	R3A-R3B	If pressure pump 2 is installed
Output 4	Stop all pumps	R4A-R4B	Required

Stop outputs can be changed to NC behavior with DWCONTACT# when the installation requires it.

Required operating-status feedback

With the Viking default JPDI1-JPDI4 = Position S, connect each pump-running contact across the listed terminals. The signal must be active when the pump is running.

Input	Pump	Terminals	Signal	Condition
Input 1	Submersible pump	DI1-GND	S0/NPNNPN is a negative signal (minus).; JPDI1 = S.	Required
Input 2	Pressure pump 1	DI2-GND	S0/NPNNPN is a negative signal (minus).; JPDI2 = S.	Required
Input 3	Pressure pump 2	DI3-GND	S0/NPNNPN is a negative signal (minus).; JPDI3 = S.	If pressure pump 2 is installed

Stop-circuit note: NC output mode depends on the FlexVander controller being powered and functioning. For stop circuits that must not depend directly on the controller, use a normally-open FlexVander output to drive an interposing relay and use the relay's NC contact in the stop circuit.

Optional standard features

Local push buttons

Local push buttons are optional physical inputs for local pump operation at the installation. Use FVALOCIN to select which digital input is used for the local push button.

Input	Function	Terminals	Signal	Condition
Input 1	Local push button	DI1-GND	S0/NPNNPN is a negative signal (minus).; JPDI1 = S.	Program 1 only
Input 4	Local push button	DI4-GND	S0/NPNNPN is a negative signal (minus).; JPDI4 = S.	DI4 not assigned to another function
Input 5	Local push button	DI5-DCOUT	PNPPNP is a positive signal (plus)./positive input referenced to GND; no JPDI jumper or S0 mode.	Use a positive feed; GND is the input reference.

Pressure control

FlexVander LX9 pro can be installed with or without pressure control. If pressure control is used, connect the pressure transmitter to the relevant analog input and configure Pressure Control Settings.

AI1 is shown as Pressure line 1 in Emiko, and AI2 is shown as Pressure line 2 when separate pressure transmitters are used. Viking default for AI1-AI2 is 4-20 mA with JPAI1-JPAI2 installed. See Analog Transmitter Wiring for 4-20 mA and 0-10 V wiring principles.

Input	Pressure line	Terminals	Signal
Input 1	Pressure line 1	AI1-AGND	4-20 mA transmitter; JPAI1 installed.
Input 2	Pressure line 2	AI2-AGND	4-20 mA transmitter; JPAI2 installed.

Before commissioning, verify the transmitter nameplate/datasheet and the selected input setup. Use AI2 only when separate pressure line 2 measurement is part of the solution.

RS485 energy metering

Use RS485 for energy meters when energy metering is part of the installation. Use Emiko-branded meters first where possible. See Energy Meters in Device Model for supported energy meters.

Node	Meter for	Condition
`100`	Submersible pump	Use only when a submersible pump is installed.
`101`	Pressure pump 1	Use only when pressure pump 1 has its own meter.
`102`	Pressure pump 2	Use only when pressure pump 2 has its own meter.

RS485 terminals and termination

Port	A	B	SGND
RS485 port 1	485_1A	485_1B	485_SGND
RS485 port 2	485_2A	485_2B	485_SGND

Connect 485_SGND to the common signal ground for the equipment on the bus.
Terminate RS485/Modbus at both physical ends of the bus with 120 ohm termination.
On LX9 pro, TER1 enables endpoint termination for port 1 and TER2 enables endpoint termination for port 2.
In the delivered FlexVander setup, TER1 and TER2 are installed.
A correctly terminated RS485 bus normally measures approximately 60 ohm across the pair when both terminations are present. See Serial RS485 communication.

DC outputs

Use DC outputs only when the delivered installation assigns them to supported external equipment. Check the connected equipment nameplate and the delivered setup before using the outputs.

Output	Terminals	Rating	Condition
5 V DC-Out	DCOUT5-SGND	5 V / 300 mA	Use only when included in the delivered setup.
12 V DC-Out	DCOUT-SGND	12 V / 500 mA	Use only when selected with `JP101` and the supply is at least 14 VDC.
24 V DC-Out	DCOUT-SGND	24 V / 250 mA	Use only when selected with `JP101` and the controller has AC supply.

Mini Weather Station sensors

DataGuard field sensors

Use DataGuard when Mini Weather Station values or other field values must be logged or shown in Emiko. FlexVander documents the physical input; DataGuard documents how the selected value is reported and logged.

See Climate and Level Sensors for serial instruments, Analog Inputs, Digital Inputs and Counters, and 1-Wire Temperature.

Use DataGuard via Analog Inputs for values connected to analog inputs that are not already assigned to another function. Use Analog Transmitter Wiring before configuring the DataGuard parameters.
Use DataGuard via 1-Wire for 1-Wire temperature values.
DI, serial, RS485, Ethernet, and analog-output setup must follow the documented setup page or the cabinet documentation for the installed driver.

Additional analog inputs

The LX9 pro controller provides AI3 and AI4 for additional analog field sensors when the delivered setup assigns those inputs. The connected instrument nameplate or datasheet decides whether the input is configured for 4-20 mA or 0-10 V.

Input	Terminals	Signal	Condition
Input 3	AI3-AGND	4-20 mA with JPAI3 installed; 0-10 V with JPAI3 not installed.	Only when assigned by the delivered setup.
Input 4	AI4-AGND	4-20 mA with JPAI4 installed; 0-10 V with JPAI4 not installed.	Only when assigned by the delivered setup.

Weather and field instruments

Use Instrument Families to select a supported serial instrument. Use the applicable Analog Inputs, Digital Inputs and Counters, or 1-Wire Temperature page for the other connection paths. If the instrument is not listed, use the cabinet documentation for the installed interface.

1-Wire options

Use 1-Wire for temperature measurement where the installation needs simple field temperature values, for example soil temperature. Configure the 1-Wire channel first, then add DataGuard reporting if the value must be logged or shown in Emiko.

Terminal	Use	Condition
1Wire	1-Wire bus	Use with 1-Wire Temperature Monitoring
SGND	Signal ground	Required bus reference
1Wire-LED	ID-Button LED output	Not normally used for FlexVander field temperature sensors.
