Description
TU510A controller is an auto transfer controller, which incorporating the functions
such as measuring display, control, and three remote. This controller covers three
models: TU510A-MG/MM/GG, respectively used for auto transfer control of the
dual power system, such as Mains and Gen, Mains and Mains, Gen and Gen. It
has following functions:

l Micro-computer control, complete digital technology.

l Select the running mode of controller by buttons on panel.
l LED directly displays the running status of ATS and the running mode of controller.
l Configure the running parameters by LED and buttons on panel.
l Display measuring data by LED, including voltage and frequency.
l By connecting RS485 communication port to PC (required for
RS485/RS232 interface converter) all setting values and data can be read
and wrote, and modified.

This manual is only suitable for TU510A auto transfer controller; user must
carefully read this manual first.

The descriptions in this manual, to describe expediently and avoid repetition

and redundance, are defined as following:

1. The Outline Dimensional Drawings and wirings of

Intelligent Controller

The controller is closely combined by panel and powder coated steel enclosure,
and the panel is die-casting by flame-retarded and high strength plastic. All
connections of controller are connected by pin-like and locked up terminal, easier and
more convenient to connect, move, maintain and replace the device.

1.1 Following Details:

Operation Panel W205mm x H156mm

Install Hatch W186mm x H138mm
Thickness D60mm（unconnected）

NOTE: when using, the controller must be properly grounded, well low impedance
grounded can reduce the impact from the processes of surge and transient of the
electric power system to the meter.

4.2 The Control Process of AUTO transfer for MG Model (in AUTO operation
mode) :

Operation Description
When controller is in AUTO state, Mains on Mains Gen
delay begins counting, if Mains is normal,
when time out, transfer switch closes Mains Va=220V Va=0 V
immediately, power supply by Mains, Mains
supply LED lights up. F=50.0HZ F=0.0HZ
When Mains failure is confirmed after alarm
delay or controller is in TEST state, output Mains Gen
Genset start signal to control Genset’s start.
When Genset data such as voltage and
frequency all reach setting values, Gen. on Va=0 V Va=220V
delay begins counting. When time out,
transfer switch closes Gen immediately,
power supply by Gen, Gen supply LED F=0.0HZ F=50.0HZ
lights up.

17
TU510A Auto Transfer Controller Operation Manual
NOTE: When controller is not switched on DC working power, the start signal
stays at closing state. When switch on Mains, and the controller stays at AUTO
state, the start signal will break after the setting cooling delay. If Mains failure
occurs, controller stays at the state of loss power and no display. The start signal
closes at the same time, it controls generator to start, the controller resumed to
display when the normal voltage has been set up.

4.3 The Control Process of MAN transfer for MG Model:

Operation Description
When controller is running in MAN state, Mains is normal,
press “TO MAINS” button (continue 2S), transfer switch will
close Mains, power supply by Mains, and LED for Mains supply
lights up.

When controller is running in MAN state, Gen is normal, press

“TO GENSET” button (continue 2S), transfer switch will close
Gen, power supply by Gen, and LED for Gen supply lights up.

NOTE: After output the power supply transfer signal, if the transfer switch can not
stay at Mains supply or Gen supply status, the transfer signal will keep on output
until controller’s power supply by Gen or Mains is abnormal, then it is cut off.

4.4 The Control Process of AUTO transfer for GG Model (in 1# Gen prior
operation mode) :
Operation Description
When the remote start signal is active, 1# start 1# Gen 2# Gen
signal closes, when 1# Gen voltage is normal,
1# Gen on delay begins counting, when time Va=220V Va=0 V
out, the switch closes , power supply by 1# Gen
and its LED lights up. F=50.0HZ F=0.0HZ
When 1# generator failure input is active, output 2# 1# Gen 2# Gen
start signal after confirming. when 2# Gen voltage is
normal, 2# Gen on delay begins counting, when Va=0 V Va=220V
time out, transfer switch auto transfer, power supply
by 2# Gen and its LED lights up. LED displays the F=0.0HZ F=50.0HZ
values of voltage and frequency.
NOTE: For GG model, 1# or 2# prior running time can be set by TEC parameter.
When remote start signal is active, if the controller has been in 1# prior mode, it
will auto transfer to 2# prior mode after the TEC setting time expires, after another
the TEC setting time will auto transfer back to 1# prior mode, and following the
cycle. If the setting value is 0, it will not auto transfer.

In order to make sure above menus are active, must confirm that the working
power is normal. When adopting AC working power, if voltage is abnormal, since
controller can not normally display, the related “alarm delay” is inactive, the
working power is required to change to DC supply.

Auto-transfer time (TEC):

TEC set the prior running time of 1# or 2#. If controller has been in 1# prior mode,
after Gen running expires the TEC setting time, it will auto transfer to 2# prior
mode, after anther TEC setting time it will auto transfer to 1# prior mode, and
following the cycle, if the setting value is 0, it will not auto transfer.
Transfer mode (TSM):
There are three kinds of transfer modes applied in the MG model. Set at “0” is for
auto change and auto recovery mode, which is Mains failure and start Gen. on,
when Mains resume to normal transfer to Mains on. Set at “1” and “2” are for auto
change without auto recovery modes, when set at “1” Gen. on after Mains failure,
It will not transfer whether Mains is normal or Gen. failure, it is equal to MAN state,
when set at “2” Gen. keeps on supply after Mains failure until Gen failure, if Mains
resume to normal transfer to Mains on.

The configuration and modification for parameters adopt gradually increase and
decrease, when continuously press increase or decrease button, the unit digit
changed one by one, then the tens digit changed after ten unit digit changed, follow
this logic, and the hundreds digit changed after ten. Continuously press“ ” 2s can

8. Communication Function
(It is an optional function, user can confirm whether equip or not
according to detailed condition)
8.1 Brief Introduction

The controller has an “RS CONNECTOR” communication interface , if the

interface is equipped with CI485A（CI232A）communication interface module, then
controller has “RS485/RS232” industrial standard COM immediately. The
communication interface adopts photoelectricity seclusion design and has circuit
protection function to prevent interference from common module voltage and
damage result by error connection, the RS485 adopts 9600 baud rate. The
controller that has communication function has following features:
l 100% remote signaling function, including running status and failure status.
l 100% telemetering data, including all measuring data of controller.
l 100% remote control function, covers all control functions on panel.
l 100% remote regulating, including all settable parameters of controller.

8.4 The Communication Connection for Multi Controllers

The communication interface offers user a route: from which you can get more
information that can not obtain from panel, the matching software can display all
measured parameters and status information, and can set all parameters.
The controller that has RS485 COM allows 1 communication bus can mostly
connect 247 same series of controllers by wiring connection mode. Each device
has only one ID NO., and only can be connected to PC or MODEM by matching
with another RS485/RS232 shifter in that time. Following typical wiring diagram:

NOTE: Communication cable used high quality shielded twisted-pair cable, and its
amount length must not exceed 1000m. The anode and cathode of RS485 in each
controller must be correctly connected, and the cable shield only can be grounded
at one side.

8.5 Communication Protocol
RS485 mechanism is a kind of network format of character stream signal through
between computer and hardware device. When controller is working, it adopts
9600 baud rate and MODBUS-RTU communication protocol. When it is working,
computer will send out a string of instruction to controller and then waiting for the
return data string.
NOTE: the maximum word amount of read and write, read is 16, write is 14, and
write only can use continued write command 10(hex).
