1OVERVIEW
HAT820 series dual power ATS controller is an intelligent dual-power switchover module with
configurable function, automatic measurement, LCD display, and digital communication. It combines
digitization, intelligence and networking together. Measurement and control process can be
conducted automatically, which reduces artificial operating mistakes, so that it is the ideal option for
dual-power switchover products.
HAT820 series dual power ATS controller is composed by the powerful microprocessor in the
core, which can precisely measure the voltages (2-way 3-phase) and make accurate decision for
abnormal voltages (overvoltage, undervoltage, overfrequency, underfrequency, phase loss, reverse
phase sequence), and putout power-off control digital signal. It has compact structure, advanced
circuits, simple wiring and high reliability, and can be widely used in electrical automatic control
system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal
administration, intelligent building and etc.

S2 Genset Start: Control S2 genset start signal output, that is, it can control S2 genset start.
8.1.2 REMOTE COMMUNICATION START/STOP CONTROL
Remote control Start/Stop orders can be sent by using MODBUS protocol and through RS485
interface.
Remote Communication Stop Control: disconnect the outputted genset start signal, that is,
control the genset stop.
Remote Communication Start Control: Control genset start signal, that is , control the genset
start.
8.2 AUTO MODE START/STOP
8.2.1 START CONDITIONS
8.2.1.1 INPUT PORT START
Set “Remote Gen On Load” and “Remote Gen Off Load” in the programmable input port setting,
and it shall not be set at the same time.
Remote Gen On Load: genset start outputs, and when the generating is normal, close the
generating breaker; when the output is inactive, disconnect the genset start output signal.
Remote Gen Off Load: genset start outputs, and when the mains is normal, close the mains
breaker; when the mains is abnormal and the generating is normal, close the generating breaker;
when the output is inactive, disconnect the genset start output signal.
8.2.1.2 GENSET START WITH MAINS ABNORMAL
When Mains is abnormal, genset start outputs; when the generating is normal, the generating
breaker closes.
8.2.2 START/STOP OF TWO GENSETS
When system type is “S1 Gen S2 Gen”, input port settings is as below:
Set “Remote Gen On Load” and “Remote Gen Off Load” in the programmable input port setting,
and it shall not be set at the same time.
Remote Gen On Load: estimate S1 or S2 start output according to start ways, and when the
generating is normal, generating breaker closes.
Remote Gen Off Load: estimate S1 or S2 start output according to starting ways, and after the
genset starts, both S1 and S2 breakers shall not be closed.
Start ways for two gensets: Cycle Gens, master and slave Gens, balance Gens Hours, Not Used.
Cycle Gens
If remote start is active, S1 and S2 shall start the engine based on circular running time. For the
first time users shall choose S1 or S2 according to the switchover priority, for example: if S1 is prior
to S2, then S1 shall first start; then countdown works according to the set S1 circular running time,
and meanwhile countdown for genset fault check starts; afterwards before the fault check
countdown ends S1 generating is normal; after that make S1 work with loading; When S1 circular
running countdown is over, S2 starts and countdown for S2 circular running starts; at the same time

HAT820 Dual Power ATS Controller 2019-05-25 Version 1.0 Page 18 of 52
countdown for genset fault check begins and before the fault check countdown ends S2 generation is
normal; afterwards make S2 works with loading; then S1 stops; In this way make it circularly working
until remote start is inactive.
If during the start process genset fault (fault check is overtime or input of genset fault is active),
breaker-close failure, loading prohibition occurs, immediately stop the current working genset and
start another genset.
During the circular running process, if it is switched over to Manual Mode it shall remain current
status, and suspend the circular running timing.
Master and Slave Gens
When remote start is active, master genset starts. During the start process present genset fault
(genset power supply delay is overtime or input of genset fault is active), breaker-close failure,
loading inhibition occurs, immediately stop the current working genset and start another genset,
otherwise current genset keeps on starting until remote start is inactive.
Balance Gens Hours
When remote start is active, the genset with shortest accumulated running time starts. During
the starting process present genset fault (genset power supply delay is overtime or input of genset
fault is active), breaker-close failure, loading inhibition occurs, immediately stop the current working
genset and start another genset, otherwise current genset keeps on starting until remote start is
inactive.
If it is demanded to do Start/Stop operation on two gensets, the following conditions are to be
satisfied.
1) It shall be active under Auto Mode;
2) Set system type “S1 Gen S2 Gen”;
3) It is needed to set “S1 Genset Start” and “S2 Genset Start” in the output port;
4) It is needed to set “S1 Genset Fault Input”, “S2 Genset Fault Input” and “Remote Start On
Load” or “Remote Start Off Load” in the input port;
5) It is needed to set “Gen-Gen Start Mode”;
6) “Genset Available Time” shall be configured; if start mode is circular starting, it is also needed
to set “S1 Cycle Work Time” and “S2 Cycle Work Time”;
“S1 Genset Fault Input” and “S2 Genset Fault Input” in the input ports are optional settings.
Genset fault can also be checked from “Genset Available Time”, and it is needless to input genset
fault status by input port.
If the starting mode of the two groups of gensets is set “Not Used”, then genset starting signal
shall not be outputted.

outputted.
Priority level: S1 master
8.2.3 SCHEDULE WORK
When schedule work function is enabled, users can set scheduled start time. When the
scheduled time is up, the controller shall send out starting signal. When the lasting time for scheduled
starting time is over then the starting signal is disconnected. Scheduled Genset Start can be with
loading or without loading.
Schedule Work On Load: genset start outputs, and when the generating is normal, the generating
breaker is closed;
Schedule Work Off load: genset start outputs, and when the mains is normal, the mains breaker
is closed.
The circular time for scheduled start can be set by month, week and day.
Start by month: it can be set to start in any month and the start date and time can also be set.
Start by week: it can be set to start at the same time for several days in one week; for example:
set start at 08:00 from Monday to Friday for lasting 10 hours every day.
Start by day: it can be set to start at the same time every day.
8.2.4 SCHEDULE NOT WORK
When scheduled non-start function is enabled, users can set scheduled non-start time. When the
scheduled time is up, controller starting signal is disconnected. Before the scheduled non-start
lasting time is over starting signal is prohibited.
Scheduled Non-start circular time can be set by month, week and day.
Scheduled Non-start by month: which month to not start and the non-start date and time can be
set.
Scheduled Non-start by week: it can be set to not start at the same time for several days in one
week; for example: set non-start at 19:00 from Monday to Friday for lasting 12 hours every day.
Scheduled Non-start by day: it can be set to not start at the same time everyday;
NOTE3: Scheduled non-start operation is prior to scheduled start operation.
