B. Alternator
This type alternators are brushless, self-regulating and incorporate a rotating inductor with damper cage winding and a
fixed stator with skewed slots. The stator windings have a shortened pitch to reduce the harmonic content of the output
waveform. The alternators are made in compliance with the 98/37, 73/23, 89/336 CEE directives and their amendments,
and the CEI 2-3, EN 60034-1, IEC 34-1, VDE 0530, BS4999-5000, CAN/CSA-C22.2 N°14-95 - N°100-95 regulations.
C. Power Generator Control System:
The power generator control system is an
Automatic Mains Failure Control Module.
The module is used to monitor a mains
supply and automatically start a standby generator set. The module also provides indication of operational status and fault
conditions, automatically shutting down the genset and indicating failures by means of an LCD display, and appropriate
flashing LED on the front panel.
Selected timers and alarms can be altered by the customer from the front panel. Alterations to the system are made using
the 810 interface and a PC. This interface also provides real time diagnostic facilities.
Easy push-button control
Operation of the module is via push-button controls (with security locking facility) mounted on the front panel with STOP/
RESET, AUTO, MANUAL and START push-button. The first three push-buttons feature LED ‘selected’ indications. Fur-
ther push-buttons provide LCD DISPLAY SCROLL and EVENT LOG VIEW functions.
Microprocessor control
The module features 16-Bit microprocessor control and a comprehensive list of timers and pre-configured sequences. This
allows demanding specifications to be achieved.
Event Log
The instrumentation displays are supplemented further by EVENT LOG VIEW, which shows the last 15 shutdown events
along with date and time of shutdown.
LED indication
‘Hid-‘til-lit’ icons are used to show the presence of alarm conditions detected by the module.
In addition 4 uncommitted LCD segments allow the user to configure the module to provide other status indications from
either internal states or from external digital inputs.
Digital Inputs
The module accepts the following digital inputs:
•
Emergency Stop Input - A N/C DC positive input
•
Fully configurable warning or shutdown inputs
With the exception of the Emergency Stop Input, these are configurable to be either N/C or N/O contacts connected to the -
Ve DC. The 6 fully configurable auxiliary inputs can be selected to be indication, warning or shutdown inputs either immedi-
ate or held off during start up to allow for use as protection expansion inputs. Alternatively they may be configured to
control extra functions such as Lamp Test or Remote Start input, and many others - refer to appropriate manuals for
details.
