Section : 3 Controller Electrical Connections
3.1 General Guidelines
ATS-LV 1000 controller requires a regulated 24 VDC connection from an external supply (not
provided) to work properly.
WARNING: Don’t connect AC power cables to the ATS-LV 1000 controller.
Important Notes:
•All electrical installations must be supervised by a qualified and responsible electrician.
•Use wiring practices that conform to all national, international and local electrical codes.
•Do not put sensor cables or instrument 4-20 mA output wires in the same conduit that
contains AC power wires. AC power wires require a separate conduit to prevent electrical
noise from interfering with the instrumentation signals.
3.2 Power
A 24 VDC power supply must be used to power the ATS-LV 1000 controller. The exact
connection of this power supply is shown in the given image in this section. Always separate
input DC power from high power sources, frequency drives, motors or other electrical signal
wires which may contribute noise to a system and cause disturbance in reading. ATS-LV 1000
controller has the power polarity protection which means if +ve power supply is connected to
-ve connection of controller, it will not cause any malfunctioning of controller however it will
not power on the controller. Make sure input DC power is stable, noise free and non-
fluctuating.
Note: Power wire size range: 12-24 AWG (0.205-3.31 mm2), Wire stripe length: 7-8mm

3.3 Transmitter Connection
Level transmitter cable can be connected to the ATS-LV 1000 controller terminal strip by
connecting the transmitter 4 ~ 20mA wires with IN terminals. Make sure that positive and
negative connections are connected same on both the devices. Route the signal cable away
from AC power wires, frequency drives, motors, or other electrical signal wires. Do not put
sensor or signal cables in conduit that contains AC power cables and motor cables.
Terminal blocks are labeled on controller back part.

3.4 Relay 1 / 2 Connection
dataM contains two relay outputs (Relay 1 & Relay 2) which can be connected to the ATS-LV 1000 controller terminal
strip by inserting the wires in Relay 1 and Relay 2 connection.
•This connection can be used for RELAY function. Connect top (red marked connection) with positive terminal and
bottom (blue marked connection) with negative terminal. (same for Relay 2 yellow and green)
Note: Connection wire size range: 20-26 AWG (0.13-0.52 mm2 ) , Wire stripe length: 7-8mm
3.5 RS485 A & B Connection
Two RS485 communication cables can be connected to ATS-LV 1000 controller terminal strip by inserting the wires in
RS485-A , RS485-B connections.
•Connect top purple marked connection with RS485-A terminal and bottom green marked connection with
RS485-B terminal.
Note: Connection wire size range: 20-26 AWG (0.13-0.52 mm2 ) , Wire stripe length: 7-8mm
