The ST140 Pump Station allows you to remotely monitor and control VFD, So!Start, Contactor and Relay driven pumps.
Each ST140 contains a cellular modem with connection to the Altrac Cloud. Using the Altrac Web App you can control your
pump on your smartphone, tablet, or desktop computer. The ST140 also has a physical button you can use to turn the
pump on and offwhen you don’t have access to a smart device.
The Pump Station monitors and controls up to two pumps. It is designed to control a primary irrigation pump and a
secondary pump such as for fertigation or sulfur burner. The ST140 monitors pump state(s), HOA switch position, a flow
meter, and two pressure sensors for irrigation line pressure.
The Pump Station sends and retrieves data from the cloud every 10 minutes while connected to a power source. During
pump operation, the Station updates every 5 minutes or less. If a sensor value changes dramatically the Station will update
immediately.

Standard Modes
Each ST140 includes a cellular modem. The modem automatically connects
to the cellular network when the device has power. You may see the following
states below.
The cellular modem is located on the top right of the circuit board. The
modem is removeable in case of damage or obsolesence. To remove, detatch
the antenna by gently pulling up on the gold u.Fl antenna connector. Without
exterting pressure on the top of the modem, pull up on the sides to remove
the modem from its headers.
Connecting to the Cloud
When the device is in the process of connecting to the cloud, it will rapidly
blink cyan. You o!en see this mode when you first connect your device to a
network, a!er it has just blinked green.
Connected
When it is breathing cyan, your device has successfully connected to the
Internet.
Looking for Internet
If your device is blinking green, it is trying to connect to the cellular tower.
The states below are the normal sequence you will see on startup.

When your device is connected to cellular but not to the cloud, the LED will
breath green.
If you see the above state or any other color, please contact [e-mail]
The modem is the most sensitive part of the ST140. Removing the antenna connector or modem
without the proper tools could void your warranty. Contact Altrac. We’re happy to help.

Internal Antenna
The ST140 has an antenna mounted inside the enclosure. Because of this, mounting location of the ST140 can
affect cellular signal strength. You can check the cellular signal health of your device by navigating to the settings
tab in your Altrac account.
Cellular signal quality. Higher
numbers are better.
Cellular signal strength of the
device. Lower numbers are
better.
Quality
Signal Strength
Signal Strength
RSSI stands for 'Relative Signal Strength Indicator'. Any reading under 100 is acceptable and should not have trouble
connecting. Anything over about 105 RSSI will be unstable with weather / congestion variances.
Signal Quality
Typically a quality of 0 means noise levels are high enough to not have a connection. A quality value of 49 is a solid
noise free connection. In some scenarios a device will have a good RSSI reading, and bad signal quality reading; in
this case you may need an external antenna (CN102).
Mounting Location
• As high above the ground as practical.
• In an area clear of vegetation.
• Orient the right or le"side of the ST140 to face the cellular tower.
• Rotate your device 90 degrees (keep connectors facing the ground). O"en, the internal antenna picks up signal
better in certain orientations.
• Metal weakens cellular signals. If possible keep the device away from metal, or if signal is weak, change location of
the device to the opposite side of a metal cabinet.
• Add an external antenna to the device.

External Antenna
N-Type to SMA Connector
External Antenna
If you have followed the troubleshooting tips on the previous page and still have weak signal, you likely need an
external antenna to boost the cellular signal strength. The antenna comes with two components: the antenna
and the connector. Contact your distributor or [e-mail] to purchase the antenna.
Installation
You will need to install the N-type connector to the bottom of the ST140.
Step 1: Remove the plug from one of the pre-drilled holes on the bottom of the ST140 enclosure.
Step 2: Use the nut to attach the N-type connector (large silver side) to the enclosure.
Step 3: Remove the existing internal antenna SMA connector (smaller and gold side)
Step 4: Attach the new SMA connector to the mating SMA part on the circuit board.
Mounting
• As high above the ground as practical.
• Above any metal sheeting or cabinet.
• In an area clear of vegetation.

Backup Battery
The ST140 includes a backup battery designed to power the device for up to 3 hours during a power outtage. This
battery will not allow the pump to continue operating, but it does allow the ST140 to notify the user when their
pump has lost power. The battery is not required for operation.

Relay Specifications
Contact Ratings: 6A, 250VAC, 85°C, Cycles: 30x10^3
Approvals: VDE Cert. No. 40023970, UL E214025, CQC 12002066685
The ST140 has 2 onboard relays for controlling a primary and secondary pump. The relays are controlled
independantly through the Altrac webapp or physically through the ‘test switches’ on the PCB.
Setup B: Contactor or Relay Driven Pump
Using Relay 1, you can control a secondary relay or contactor rated for the pump’s amperage and voltage. DO
NOT use the ST140 to directly drive a pump. In typical contactor installations, a contactor is driven by a switch or
by a relay then a switch. The switch is turned on by the operator; the switch turns on a relay (“drive relay”),
which then turns on a contactor, which feeds power to the pump.
To install the ST140 in the above scenario, you would “break” the wire coming from the switch to drive relay
with the Relay 1 NO and COM terminals.
Setup A: VFD or So!Start Driven Pump
VFD and So!Start (“inverter”) driven pumps are typically controlled by a 2-wire circuit. Wire 1 is connected to
the inverter’s common terminal (typically labeled “COM”, “SN” or “+24V”); Wire 2 is connected to the inverter’s
control input terminal (typically labeled “S1”, “DIN1”). When the two wires are connected, typically with a Hand-
Off-Auto switch, the inverter will engage the pump; when the wires are disconnected the inverter will disengage
the pump.
To install the ST140 in with an inverter wired for 2-wire control, use Relay 1 COM and NO to “break” the signal
between Wire 2 HOA switch and Wire 2 inverter control input terminal. When installed, the operator will be able
to turn the pump on only when the “HOA” switch is in the auto position and the ST140 is set to run the pump.
If an inverter is setup for 3-wire control (an “Off” button and an “On” button) or other forms of control, we
recommend having your electrician convert your inverter to 2-wire control before installation.

To test the relay functionality without access to the Altrac webapp, you can open the enclosure and check the relay
status LEDs or physically switch the relays ON/OFF. When not testing, the relay switch should be in the le!‘OFF’
postition.
Relay 1 and relay 2 each have a status LED. The LED in the top right
corner of each relay terminal section turns ON (RED) when the relay is
ON.
You can also test the relays by turning the equipment ON/OFF
through the Altrac webapp. Click the State tile to ‘ON’ to turn the
equipment ON. It may take up to 10 minutes for the ST140 to
download the instructions and switch the relay.

Relay 1 and 2 each have a physical switch. The switch is located
directly above the relay on the circuit board. When the switch is ON,
the relay and assocaited LED will also turn ON. If the relay is already
ON, the switch will not affect the relay.
