USER MANUAL
POWER CONNECTIONS/OPERATIONS
INPUT PWR: The I/O module requires 24Vdc, 2.5A (60W power supply) for operation.
The acceptable range is 19~28Vdc. An alarm notification can be sent after a programmable delay if the input
power is no longer present.
BATT (12V): A single 12V lead acid battery is required for backup operation and to receive Power Loss
alarm notification. Do not use Li ion or other battery technology. Only use Sealed Lead Acid (SLA) type
batteries 2Ah to 10Ah. The 12V from the battery is converted to 24Vdc internally.
FUSED OUT: A 24V, 650mA auxiliary output power is available for external devices. This ouput will continue
to deliver 24V after the power is removed from the INPUT PWR terminals and operate off the battery. (DCUPS) The autonomy will depend on the battery capactiy and load. This circuit has an electronic fuse with an
auto-reset feature.
POWER ON/OFF switch and indications:
Batt Fuse: 3A battery fuse (automotive type - ATOF).
Input PWR Fuse: 3A 24Vdc incoming power fuse. (automotive type - ATOF).
Fuses are removed during shipping. They are kept in a small bag with the schematics.

ANALOG INPUTS
6 analog inputs: 4-20mA differential and optically isolated.
12-bit resolution: (4-20mA = 800-4000 counts)
For loop powered instruments, use the +24V terminal for excitation voltage.
Connect the signal to Alx+, and connect the Alx-terminal to COM.
Loop Powered
DIGITAL INPUTS
NPN circuitry. (Inputs are at 12Vdc, and COMs are Signal ground)
Connect to COM to activate the input.
Only use potential free contacts to trigger the inputs (dry contacts)

FLOWMETER CONNECTION
It is possible to monitor both the instantaneous flow (4-20mA) and the accumulated volume (Digital
inputs D5, D6). Below is a connection example of a magnetic flowmeter. Please refer to your
flowmeter manual and/or contact your supplier for setup and wiring assistance.
AC
4-20mA
(Instant flow)
Digital Output
(Totalizer)
The 4-20mA signal can be connected to any of the open Analog inputs (AI1~AI6). This signal
from the flowmeter is typically not loop powered.
A pulse output from the flowmeter is required for volume totalization.
There are 2 digital inputs on the FLEX Module (D5 &amp; D6) designed for volume totalizer derived
from a gallons/pulse signal (example 100 gal = 1 pulse). The max input frequency is
100 Hz. The minimum pulse width is 0.5ms.
Note: These 2 inputs are not for monitoring a frequency output proportional to the flow. When
the wiring and flowmeter configuration is complete, the value for the gallons/pulse found in
“Parameters” screen on the web portal must also be changed to match the flowmeter.

RELAY OUTPUTS
Rated for 250V, 5A (resistive)*
R5 and R6 are Normally Closed (NC) and open upon activation.
Each relay will only activate for 2 seconds (momentary) when the button is pressed on the web portal.
CAUTION/DANGER
R1-NO R2-NO R3-NO
Machine may start unexpectedly and cause serious injury or death.
You must have confirmation that all personnel are free and clear
from moving parts and the electrical panel before activating the
relay remotely.
Only allow qualified operators to remotely activate the relay.
The relay remote operation must be part of a fail safe electrical
circuit that would shutdown the equipment before failing or cause
damage/injury.
R4-NO R5-NC R6-NC
Local and National safety codes must be followed.
RS 485 PORT BAUD RATE
The baud rate can be set via the dip switches on the FLEX Module.
The default is 9600 (required for communication with the SJE Panel Link™).

INPUT SCAN TIMES
The odd number analog inputs AI1, AI3, AI5 have a scan time of 30s or less from the SJE Panel Link™
Gateway. The even number analog inputs AI2, AI4, AI6 have an update time of 90~120s update time.
Choose even number AIs for alarms requiring a longer time delay. Digital inputs have a 10s or less
scan time. Digital inputs also have a programmable time delay function that can be accessed in the
“Parameters” screen.

LIFT STATION - WEB PORTAL
The lift station web portal can be applied to the FLEX to monitor a duplex or triplex lift station.
In addition to the graphic change, it can monitor pump and station flows via volumetric flow
calculations. The current monitoring can be configured to only update when the pump is
running. The analog inputs are assigned as follows:

WEB PORTAL UPDATE FREQUENCY
The data is sent from the Gateway to the cloud server via cellular communication every 10 minutes for
updating the values on the portal and for data logging. This time period is interrupted if there is an alarm
or if the user presses “Get Status” on the web portal, in which case the data is sent immediately.
