1. GENERAL DESCRIPTION
1.1 INTRODUCTION
This module controls up to three power sources: mains and two generators (MGG). It is also possible
to configure it to control mains and one generator (MG) or just two generators (GG). It features
isolated measurement of the voltages and frequency on all three sources as well as the current on the
load side. It has four operating modes selectable by the user: OFF, AUTO, MAINS, G1 or G2.
This module can be configured to be used as ATS or ATSO.
The user interface consists of a Graphical LCD display. A mode push button is provided to select the
operating mode and four push buttons are used to access a menu of parameters. The menu gives
access to all timers, set points and other parameters relevant to the control and protection of the
installation.
This module comes with RS485, USB and Ethernet communication ports. It also features a 4GB
MicroSD card for data and event logging. Data and event retrieval is done by either USB port or
Internet through a dedicated website.
The firmware could be easily upgraded on site via the USB interface using a desktop application or
any smart phone with a free Android app.

1.3 OPERATION
Four operating modes are provided. To switch from one mode to another, press the mode push button till
you reach the required operating mode and then wait for 2 seconds for the operating mode to be applied.
Following is description of the operating modes:
OFF: In this mode the module cuts power completely from the load.
AUTO: In MGG and MG installation,the module monitors the Utility supply. When the Utility fails or its
contactor fails to engage, the module counts a “Response” delaybefore starting the genset.
In GG installation, the module monitors the remote control input. When the remote control input becomes
active, the module counts a “Response” delay before starting the genset.
The genset is started only if it is in Ready mode.
In MGG and GG installation:
oFor ATS type: Following a mains failure, G1 or G2 is started depending on the “Alternate
hrs”after a “Response” delay. Load is engaged after the elapse of the “Warm-up” delay.
If “Alternate hrs”is set to a value of hours, the genset with the less number of run hours is
started.
If “Alternate hrs” is set to G1/G2, G1/G2 is started.
Once a genset is feeding the load, it keeps feeding it for the number of hours set in
“Alternate hrs”.
oFor ATSO type: Following a mains failure, G1 (the smaller genset) or G2 (the bigger genset)
is started depending on the “Req priority”after a “Response” delay. Load is engaged after
the elapse of the “Warm-up” delay.
If the “Req priority” is set to Ld, G2 is requested if the load prior to mains failure was above
the “G1 Max Load %”, Otherwise, G1 is requested. The value of the load supplied by the
Mains is retained for 5 minutes only. So if 5 minutes have elapsed from the mains failure, G2
is started always. This could occur when switching to AUTO mode from Mains or OFF
modes.
If the “Req priority” is set to G1/G2, G1/G2 is requested independently from Load.
If G1 is feeding the load and the current goes above the “G1 Max Load %” for a “G1 MaxLd
del”delay, G2 is requested. If G2 is feeding the load and the current goes below the “G2
Min Load %”for a “G2 MinLd del”delay, G1 is requested.
1. GENERAL
DESCRIPTION

When the Mains is re-established, the power is switched back with a dead transfer time “Transfer”
after a restoration delay “Mains Rest.”and the genset is shut down after the elapse of the “Cooling”
time. For MGG and GG installation, in case the requested genset fails to start or its contactor fails to
engage or it shuts down due to any fault, the other genset will automatically start and supply the load.
If the “Hold Start”is enabled, and in case the genset failed to start, the start signal remains on so that
when it restarts, it will feed the load after disengaging the running genset. When the “Hold Start” is
disabled, the start signal is removed. Manual reset is required to recover from this failure. Please refer
to section 2 for display description.
Mains: The module monitors the Mains supply. The load is fed exclusively from this supply if it is within the
acceptable limits. No gensets will be started if the Mains fails.
G1: In this mode, G2 is always in standby mode. G1 is started when it is in ready modeand the Mains fails.
G2: In this mode, G2 is always in standby mode. G1 is started when it is in ready modeand the Mains fails.
In case contactors are used for the transfer switch, each contactor is controlled by one dry contact. The
other dry contact is used as an alarm output (CxD.NO).
If motorized circuit breakers or changeover switches are used, each motorized breaker/ switch is controlled
by two relays. The first has one normally open dry contact (CxENG) and is used to engage the motorized
circuit by giving a pulse of 2 seconds, the second is controlled by a contact that has a common (CxC),
normally open (CxD.NO) and normally closed (CxD.NC) contacts to disengage the motorized circuit breaker
by giving a pulse of 4 seconds.
Presettable in the menu. Refer to Section 2.4

DESCRIPTION

2.5 PARAMETERS DESCRIPTION
The over/under frequency/voltage could be disabled by setting the corresponding parameter in the menu to
'N'.
When transferring load from one generator to another, the transfer dead time and the warm up delay are
counted. To avoid getting a fault on the generator, the sum of these delays should not exceed the start fail
delay of the generator. Thus, the “Start Fail”delay should never fall below (“Transfer” + “Warm-up”+10sec).
When “Hold Start”feature is enabled, the start signal is held on the generator after a start failure or an OK
failure fault occurs. Thus, when this fault no longer exists, the generator starts without user intervention.
When it is disabled, the start signal is removed and a manual reset of the fault is required to resume use of
the specific generator.
For ATS, the “Alternate hrs” parameter indicates the number of hours that a generator must run before the
other generator is requested. If set to G1, G1 is given priority and if set to G2, G2 is given priority.
The “Weekly Ex.”parameter enables/disables the weekly exerciser. When enabled, any generator that did
not operate between Sunday and Friday would be started on Saturday at 8:00 am for half an hour. If both
were not used during the whole week, they will be started on Saturday at 8:00AM in sequence and each for
half an hour.
The “Time Switch” manages the operating time of the genset daily. Two parameters control the daily time
switch: “Ready @” and “Stdby @”. “Ready @” sets the time at which the genset becomes ready. “Stdby @” sets
the time at which the genset goes to standby mode. If genset is required to be in ready mode all day then set
“Time Switch” to N.
The “All Days Ready”manages the operating time of the genset weekly. Under “All Days Ready”, if Y is
selected then the genset will be ready all week long. Otherwise, the genset will be ready only in days set to Y.
It will be in standby in days set to N.
As a result, the genset will be ready during the hours set by “Ready @” and “Stdby @” only on days set to Y
under Rdyday.
When “R.C.” is set to “Gensets Rdy”, when remote control is active and genset in ready mode, following a
mains failure, the genset is started. Otherwise, the genset is stopped.
When “R.C.” is set to “U Present”, when remote control is active and genset in ready mode, the genset is
stopped.
When “R.C.” is set to “v1.0 Compt.”, the remote control input will be at the place of CM F/B as in
