General description
ATS-I controller allows an automatic transfer switch commutation between mains and
generator.
In automatic mode, when faulty mains conditions are detected, the board sends a remote
start signal to the engine; when generator is running, the phase sequence is checked, if
voltage and frequency measurements are compatible with programmed values, the
changeover switch is activated towards generator side.
When mains voltage returns back, transfer switch returns on mains side and generator is
stopped.

Device operative logic
There are two operative modes:
- Manual
- Automatic
At the startup, device selects automatically the correct operative mode in accordance with
P13 parameter; “Aut/Man” key allows to change operative mode without restriction.
Front view:
Manual mode
In manual mode all system is controlled by ATS-I operative panel, on the left side of the
display, a label shows the actual operative mode of the device (“ MAN “ or “ AUTO “).
“Start Gen” button allows to start and stop the generator; in case of idle generator, when
“Start Gen” button is pushed, a blinking key icon will appear near “MAN” indicator to signal
a starting phase for generator; when running engine is detected, the key become
permanent. To stop the engine “Start Gen” key must be pushed again ( key icon will
disappear).
To switch contactor status from mains to genset, push “Generator” key: Generator icon
will appear near frequency indicator, this icon blinks until feedback voltage is detected:
from that moment, the icon becomes permanent.
Push “Generator” key a second time to disconnect generator line without switching; push
“Mains” key to switch contactor status from genset to mains, a icon will appear near
frequency indicator, this icon blinks until feedback voltage is detected: from that moment,
the icon becomes permanent.
On display is possible to check mains line voltages, generator line voltages and
frequency.

To read mains voltages, push “Select Mis” key until “L” indication will appear on the left
upper corner; at this point mains voltages will be showed on display. Push “Select Mis”
again and “G” icon will appear; generator line voltages will replace mains measure. If
generator is not running, “OFF” icon will appear which means unavailable genset
measurements.
The commutation is immediate (500ms delay from opening a contactor and closure the
other) and a phase sequence check is performed each switching procedure.
In manual mode, operative generator alarms are not detected, are available only
indicators LA and LM. “M” letter on the right side means single-phase system.
Automatic mode
Automatic mode allows to manage engine and transfer switch completely by software
logic, it’s not possible to start the generator or force switching through operative board,
“AUTO” indication will appear on the low left corner.
However with “Select Mis” is still possible to change displayed measurements from
generator and mains. When controller commands switching on mains or generator,
automatically values visible on display change in accordance.
Each phase is checked separately, so a phase failure will start the automatic intervention
procedure.
Alarms
If mains measurements are selected, in case of alarm will be possible to see one of these
messages on the left side of the display :
- “LOW VOLT” line voltage below programmed threshold ( P3 parameter );
- “HIGH VOLT” line voltage over programmed threshold ( P4 parameter );
- “PH.SEQ.ERR” in case of wrong phase sequence;
Both alarms cause an automatic intervention procedure.
Generator starting procedure begins after a programmable delay (P7 parameter).
With running generator, after another programmable timer ( P8 parameter), the controller
checks voltage status measured on alternator and in case of anomaly, one of these
alarms will be showed on display:
- “ERROR 1” if generator’s phase voltage is out of limits. ( P5, P6 parameters ).
- “ERROR 2” if generator’s frequency is out of limits. ( P12 parameter ).
- “ERROR 3” if generator fails to start.
If generator is working correctly, “ERROR 1” or “ERROR 2” alarms are showed if voltage
or frequency values are out of limits for the duration of programmed time ( P15 parameter)
To reset an alarm on display must be used “Aut/Man” with locked keyboard ( “LOCK”
key). The device returns on mains position and restarts commutation procedure towards
generator. If generator alarm is active and mains voltage returns back, automatically the
commutation will be switched on mains side.

Automatic transfer switch procedure mains-generator, generator-mains
Initial configuration with mains OK (voltage values inside programmed thresholds)
R = Mains
G = Generator
When mains voltage is outside programmed limits (P3 and P4 parameters) for a delay
time (P7 parameter), the intervention process starts; at the end of this period, the engine
is started too and the controller waits for stable measurements for a delay time (P8
parameter), otherwise a “ERROR 3” message will be displayed.
With stable voltage and frequency values, after a delay time (P10 parameter) the
commutation is switched on generator side; if voltage check fails, “ERROR1” occurs, if
frequency check fails, “ERROR2” occurs, if phase sequence detection fails,
“PH.SEQ.ERR” occur. In these cases the generator is stopped. Between mains contactor
opening and generator contactor closure there is constant delay time of 500ms.
Transfer switch remains on generator side until mains voltage returns in a stable way in
accordance with programmed delay time (P10 parameter).

With mains ok, generator contactor opens and after 500ms mains contactor is closed.
After cooling time (P11 parameter) the generator is stopped.
With running generator, if voltage and frequency value are outside programmed
thresholds ( P5, P6 and P12 parameters) for a delay time (P15 parameter), the device will
show an error message and the generator is turned off. In this case with “Aut/Man” key or
when mains returns back, the device returns to the mains OK status where generator
contactor is opened and mains contactor is closed.

Parameters Programmation
Parameters programmation can be performed without operative mode restriction. Hold
“UP” and “DOWN” keys at the same time for 5 seconds to open programmation menu; the
word “PROG” will be displayed with the indication relative to P1 parameter, with “UP” and
“DOWN” keys is possible to scroll all parameters and select the one you need to change
with “Select Mis” button. The chosen parameter begins to blink and will be possible to
edit the value with “UP” or “DOWN” keys. Each increase/decrease command, the value
will be modified by 1 unit. Hold the button to raise inc/dec speed by 1 unit every 500ms,
and after 30 step, by 10 units every second. The old values ( “xxx:” ) is showed on the left
side of the colon, the new one ( “:xxx” ) on the right side.
To confirm the new value push “Select Mis” key, the parameter finish to blink and will be
possible to select another value. To exit programmation mode and save changes made,
hold “UP” and “DOWN” keys at the same time.

Voltage threshold limits change with 1% step, delay time change with 1s step, frequency
range change with 1 Hz step, all other parameters have editing step in accordance with
their range values.
Special functions: Phase sequence detection, hour meter, battery voltage
Phase detection function can be enabled for both mains and generator three-phase
systems with a special parameter ( P16 parameter).
The function, in case of the generator, is active both in automatic and manual mode. If in
automatic, the message "PH.SEQ.ERR" appears and the closure of the relative contactor
is inhibited; if in manual, the word doesn’t appear but the "generator" icon remains
flashing and the closure of the relative contactor is however inhibited. The same function,
in case of the mains, is active both in automatic and manual mode and it’s the same in
both cases: the "mains" icon remains flashing, the "PH.SEQ.ERR” message appears and
the closure of the relative contactor is inhibited. To reset the alarm can be used “Select
Mis” key. Then the device repeats the whole control and switching procedure.
WARNING!!! If the supply voltage 12/24Vdc is not connected to the board, the board
turns-off; but if the mains voltage is present with board off, the mains contactor is closed
even if the voltage values and/or the phase sequence are not correct.
