1OVERVIEW
HAT828 High Speed ATS Controller is a dual power transfer module that can output switch
transfer signals within 15ms in the case of any power outage, and synchronously transfer when both
power supplies are normal. It is suitable for PC two-stage transfer switch (high speed and normal).
With embedded operation system, it can precisely detect 2-way 3-phase voltage and make accurate
judgment for voltage abnormal situation (over voltage, under voltage, over frequency, under frequency,
loss of phase, reverse phase sequence). It also has configurable input/output, LCD display, digital
communication and other functions.
HAT828 High Speed ATS Controller combines digitization, intelligence and networking.
Automatic measurement and control can reduce incorrect operation, which is an ideal option for dual
power transfer. With compact structure, advanced circuits, simple wiring and high reliability, it can be
widely used in electric power, post and telecommunication, petroleum, coal, metallurgy, railways,
municipal administration, intelligent building and other places with high requirements for power
reliability.

7.2 AUTO START/STOP
7.2.1 START CONDITIONS
7.2.1.1 INPUT START
Set input port as “Remote Start On Load” or “Remote Start Off Load”, both could not be set
simultaneously.
Remote Start on Load: When the input is active, genset close relay will active after genset is
normal; when the input inactive, genset will stop automatically.
Remote Start off Load: When the input is active, mains close relay will active after mains is
normal; when the input inactive, genset will stop automatically.
7.2.1.2 GEN START MAINS NG
When mains is abnormal, genset start outputs, gen close relay will active after gen is normal.
7.2.2 TWO GENSETS START/STOP
When system is “S1 Gen S2 Gen”, input port setting is as follows:
Set input port as “Remote Start On Load” or “Remote Start Off Load”, both could not be set
simultaneously.
Remote Start on Load: Detect S1 or S2 start output according to start mode. Gen close relay will
active after gen is normal.
Remote Start off Load: Detect S1 or S2 start output according to start mode. Both genset S1
close relay and S2 close relay are deactivated after genset start.
Start Mode: Cycle Run, Master-Slave Run, Balanced Run, None.
Cycle Run
When remote start is active, S1 and S2 cycle run start will according to the cycle run time. When
firstly start the genset, choose “S1 Start” or “S2 Start” depends on “Priority”. e.g. S1 start firstly if “S1”
has higher priority. Then S1 cycle run countdown is started according to the preset delay. At the same
time, genset fault delay will be initiated. If S1 genset is normal before the fault delay has expired, S1
will take load; S2 start after the preset S1 cycle run delay has expired and the S2 loading process is
same as S1. S1 will stop automatically after the S2 takes load successfully. S1 and S2 will cycle run
in this way alternately until the remote start signal deactivated.
During the start process, if there is genset fault alarm (genset fault delay overtime or genset fault
input is active), fail to close or load inhibit alarm occurs, the starting genset will stop immediately and
the additional genset will start automatically.
During the cycle run process, if “Manual Mode” is selected, the current status will be hold and the
“cycle run countdown” will be suspended.
Master-Slave Run

HAT828 High Speed ATS Controller User Manual Page 20 of 56
Master genset will start when remote start signal is active. During the start process, if there is
genset fault alarm (genset supply delay overtime or genset fault input is active), fail to close or load
inhibit alarm occurs, the starting genset will stop immediately and the additional genset will start
automatically. Otherwise, the master genset will run continuously until the remote start signal
deactivated.
Balanced Run
The genset which has the shortest running hours will start when remote start signal is active.
During the start process, if there is genset fault alarm (genset supply delay overtime or genset fault
input is active), fail to close or load inhibit alarm occurs, the starting genset will stop immediately and
the additional genset will start automatically. Otherwise, the current genset will run continuously until
the remote start signal deactivated.
In system of “S1 Gen S2 gen” to start/stop genset should meet following several conditions:
1) It is active in Auto mode;
2) System type set as “S1 Gen S2 Gen”;
3) Output should be set as “S1 Genset Start”and “S2 Genset Start”;
4) Input should be set as “S1 Genset Fault Input”, “S2 Genset Fault Input”and “Remote Start On
Load”or “Remote Start Off Load”;
5) Should set the system as “Two Gensets Start Mode”;
6) Should configure set “Genset Supply Delay”, If start mode is cycle run, also should set “S1
Cycs Run Time”, “S2 Cycs Run Time”.
Among input ports, “S1 Genset Fault Input”, “S2 Genset Fault Input” are selective setting, genset
fault can be judged by “Genset Supply Delay” and there no need to inquire the fault alarm via input
port.
When two gensets start mode configured as “None”, there is no genset start signals output.
For example:
