1 SUMMARY
HAT220A/HAT240A ATS controller has microprocessor as its core, can accurately
detect 2 ways-3 phase, 2 ways-1 phase or 2ways-2phase voltage and also can make
accurate judgment to conditions of abnormal voltage (loss of electricity, over or under
voltage), control ATS to transfer after delay. Controller also has a function of sending
start signal to genset when one power is abnormal.
2 PERFORMANCE AND CHARACTERISTICS
Controller detect multi-voltage conditions, such as 2ways-3phase voltage, 1phase
voltage (could be 2 ways mains, 2ways gens, or 1mains-1gens), or 2ways-2phase
voltage. Its performance and characteristics show as following,
◘Realizing the computer programming control, can use computer to set abnormal
voltage delay, switch priority, genset shutdown delay, the voltage correction and
other functions, fully graphical interface operation. When programming by computer,
the controller front panel must be opened, then use SG72 interface module (USB to
LINK) via the PC test software. About PC software’s operation, please refer to
“software manual of HAT220A/HAT240A”.
◘The voltage normal delay of #I or #II can be set (0~60) seconds and the start Genset
delay can be set (0~90) seconds.
◘The voltage abnormal delay of #I or #II can be set (0~60) seconds and the stop
Genset delay can be set (0~90) seconds.
◘“#I power supply priority”, “Auto/Manual”, “No priority”and “#II power supply
priority”can be set via controller front panel and in order to ensure #I power supply
priority power on or #II , or no priority power on for examine and repair.
◘Design of 2 ways N line isolate.
◘LEDs mounted on front panel can clearly show ATS running status.
◘The #I and #II power supply transfer relay’s (CLOSE 1#, CLOSE 2#) output
contactor capacity is 16A 250VAC/16A 28VDC, and they belong to passive contactor,
can be directly used in driving switch to transfer.
◘The Genset start relay’s (GENS START) output contactor capacity is 7A 250VAC/7A
28VDC, and they belong to passive normally closed contacts.
◘Controller has strong ability for anti-electromagnetic interference, and very suitable
for using in strong electromagnetic interference of complex environment.
◘Modular configuration design, Flame Retardant ABS plastic shell, inserted type

5.1DELAY ADJUSTMENT
♦Adjusting potentiometer of “#I power supply normal delay”can set output delay after
#I power supply normal.
♦Adjusting potentiometer of “#II power supply normal delay”can set output delay after
#II power supply normal.
♦Adjusting potentiometer of “Genset start delay”can set genset start signal output
delay after #I power supply abnormal.
Procedures of setting “#I power supply abnormal delay”, “#II power supply abnormal
delay” and “Genset stop delay”show as following:
a) Press key and key simultaneously, when #I power supply indication lamp,
automatic status indication lamp and #II power supply indication lamp
simultaneously illuminate, loose key and key, #I power supply indication
lamp, automatic status indication lamp and #II power supply indication lamp will not
illuminate simultaneously, then controller enters into delay setting status:
1)Set “#I power supply abnormal delay”by adjusting potentiometer of “#I power

supply normal delay”;
2)Set “#II power supply abnormal delay”by adjusting potentiometer of “#II power
supply normal delay”;
3)Set “Genset stop delay”by adjusting potentiometer of “Genset start delay”.
b) After adjustment, press key, when #I power supply indication lamp, automatic
status indication lamp and #II power supply indication lamp are illuminate
simultaneously, show that every adjust values of potentiometer are saved
successfully. The controller will work depending upon setting delay values.
5.2RESTORE DEFAULT DELAYS VALUE
a) Press key and key simultaneously, when #I power supply indication lamp,
automatic status indication lamp and #II power supply indication lamp illuminate
simultaneously, loose key and key, #I power supply indication lamp,
automatic status indication lamp and #II power supply indication lamp will not
illuminate simultaneous, controller enters into delay value setting status;
b) Press key, when #I power supply indication lamp, automatic status indication
lamp and #II power supply indication lamp illuminate simultaneously, will restore
factory setting value. The controller will work depending upon default delay values.
Note: Factory setting value is 5 seconds of #I, #II abnormal delay, and 90 seconds of
genset stop delay.

7 OPERATION CONTROL
Auto/Manual operation,
When controller in running, press key to transfer controller into Auto or Manual mode
(Mode is indicated by lamps of Auto and Manual). In Manual mode, press key, load
transfer into #I power supply side and press key, load transfer into #II power supply
side.
Procedures of setting “#I power supply priority”, “#II power supply priority” and
“No priority”show as following:
a) Press key, key and key simultaneously, when #I power supply indication
lamp, automatic status indication lamp and #II power supply indication lamp
illuminate simultaneously, loose key, key and key, then automatic
status indications lamp and #II power supply indication lamp will not illuminate, #I
power supply indication lamp illuminate, then controller enters into setting priority
status.
b) Press key can circularly set three priority status:
1) When #I power supply indication lamp illuminate, at the same time #II power
supply indication lamp isn’t illuminate , for #I transfer priority;
2) When #II power supply indication lamp illuminate, at the same time #I power
supply indication lamp isn’t illuminate , for #II transfer priority;
3) When #I power supply indication and #II power supply indication lamp illuminate

simultaneously, then for no transfer priority.
c) After adjustment, press key, when #I power supply indication lamp, automatic
status indication lamp and #II power supply indication lamp illuminate simultaneously,
the setting priority value will be saved successfully, then controller will work
depending upon setting priority status.
Note: each time controller power supply is opened; priority level can be indicated by
following three conditions.
1) If #I power supply indication lamp is flashing rapidly 3 times, for #I power supply
priority;
2) If #II power supply indication lamp is flashing rapidly 3 times, for #II power supply
priority;
3) If #I and #II power supply indication lamps are flashing rapidly 3 times
simultaneously, it is no priority.
