3.3. External Protection and Isolation Devices
External devices for the protection of cables and for isolating the ATS-16 A and UPS must be installed
upstream and downstream of the equipment. Select and configure the isolating device upstream in ac-
cordance with the ATS-16 A input 16 A breakers.
Disconnecting devices must be provided in building installations and other locations.
All protection devices (circuit breakers and fuses) placed upstream of the ATS-16 A input and downstream
to ATS-16 A output line have to be installed for the protection of both the cables and the equipment and
in coordination with both ATS-16 A input protection (fuses) and ATS-16 A overload capacities.
WARNING
IF THE ATS-16 A’S OVERLOAD CAPACITIES ARE EXCEEDED, THE UNIT WILL CUT-OFF THE
OUTPUT LOAD.
DEPENDING ON THE OVERLOAD CHARACTERISTICS, THE ATS-16 A WILL EITHER TRIP THE
INPUT FUSES OR DRIVE THE INTERNAL POWER RELAYS INTO THE OPEN POSITION.

transfer to the other source of voltage
3. If both sources are abnormal, no voltage is transferred to the
output.
LED S1
(Source S1, Line status LED)
LED GREEN: Input source 1 is OK
LED FLASH: Input source 1 voltage / frequency is out of range.
LED OFF: Input source 1 failure (no power from source)
LED S2
(Source S2, Line st
atus LED)
LED GREEN: Input source 2 is OK
LED FLASH: Input source 2 voltage / frequency is out of range.
LED OFF: Input source 2 failure (no power from source)
LED SW1
(Output power state LED)
LED SW1 ON (GREEN): load is powered by input source 1.
LED SW1 OFF: load is not powered by input source 1.
LED SW2
(Output power state LED)
LED SW1 ON (GREEN): load is powered by input source 2.
LED SW1 OFF: load is not powered by input source 2.
LED F1
(Fault LED)
LED F1 ON (RED): Fault detected.
•Overload fault
•Output short circuit
•Input Source relay fault
•EPO active
LED F1 OFF: normal operation (no fault).
PUSH BUTTON BP1
(Buzzer ON/OFF)
Each 1-second push will turn the Buzzer ON or OFF.

3.7. Description of the system
The 2-pole ATS-16 A is a two-way, single phase automatic switch powered by two independent synchro-
nous or asynchronous AC power supply sources.
The ATS-16 A makes a rapid switch from one source to the other in the event of a fault to the power supply
used to power the load.
One of the two sources can be designated as the preferred power supply, to which the ATS-16 A will trans-
fer the load. It remains there until different designations or faults require it to be switched to the other
source.
The ATS-16 A is fitted with a block diagram with LED indicators, capable of providing all the information
concerning equipment operation status, together with the power source priority selection button BP2
needed to enable trained operators to make full use of the apparatus.
Features:
•Break Before Make transfer mode.
•Back feed protection (according EN62310-1).
•Complete overload and short-circuit protection. (With FUSE Holder Accessible).
•Redundant power supply. (From input Source 1 and Source 2).
•AC source detection (voltage and current detection).
•Output detection (current detection).
•LED display.
•Integrated EPO contact
•Different setting to adjust the voltage failure sensing level (+/- 12% ~ +/- 20%).
(Default setting: Nominal voltage +/- 12%).
•Protection: IP30.
•ON/OFF for Buzzer
•Selectable Nominal Frequency
•RPO active (open): output not supplied.

5. Troubleshooting
If problems should occur, please check the following points before contacting the appropriate customer
service representative:
•Is the mains voltage present at the ATS-16 A input?
•Has one of the two input fuses tripped or open?
When contacting the ABB customer service representative, please have the following information
ready:
•Device information (model name and serial number)
•An exact description of the problem (what loads are being operated, does the problem occur
regularly or sporadically, etc.)
5.1. Fault identification and rectification
Problem
Possible Cause Measure
No display, no alarm.
Mains or feeding UPS units
switched off.
Switch on the mains or feeding UPS
units.
No mains voltage present. Have the mains inspected by a quali-
fied electrician
Input fuses tripped. Check and make sure the load capac-
ity is within the specification, then
replace with new fuse. If the problem
persists, contact the appropriate
customer service representative.
Both mains indicator S1 and
S2 do not illuminate, when
mains voltage present.
Both input fuses tripped. Check and make sure the load capac-
ity is within the specification, then
replace with a new fuse. If the prob-
lem persists, contact the appropri-
ate customer service representative.
Alarm indicator F1 illumi-
nates, acoustic alarm acti-
vates with a 0.5 second se-
quence.
ATS-16 A Fault. Contact the appropriate customer
service representative.
EPO Check all loads and solve (clear) the
problem that caused the EPO.
Overheating Check and make sure the load capac-
ity is within the specification or de-
crease ambient temperature (has to
be less than 40 °C).
