Features
The Model 555 is an Automatic Mains Failure Control Module, with comprehensive instrumentation and load control option. The module is used to monitor a mains supply and automatically start and stop the engine. It indicates the operational status and fault conditions, automatically shutting down the engine and indicating engine failure by means of an LCD display, and flashing LED on the front panel.
Selected operational sequences, timers and alarms can be altered by the customer. Alterations to the system are made using the 810 interface and a PC. This interface also provides real time diagnostic facilities.
It is also possible to monitor the operation of the system either locally or remotely (Optional: Remote Communications output version only). Access to the module is restricted by PIN number.
Operation of the module is via pushbutton controls (with security locking facility) mounted on the front panel with STOP/RESET, AUTO, TEST, MANUAL and START functions. The first four pushbuttons feature LED ‘selected’ indications. Further pushbuttons provide MUTE/LAMP TEST, LCD PAGE and
DISPLAY SCROLL functions.
The module features 32-Bit Microprocessor control and a comprehensive list of timers and pre-configured sequences. User configurable expansion facilities are also provided.
The 555 module provides metering and alarm facilities via the LCD display with the following instrumentation displays, accessed via the LCD PAGE and DISPLAY SCROLL push-buttons:
Generator Volts L1-N, L2-N, L3-N
Generator Volts L1-L2, L2-L3, L3-L1

KEY FEATURES
‘Basic’ module provides a number of control and monitoring features with expansion capability to meet
demanding specifications. The ideal choice where a remote
communications control system is
specified (when used with one of the comms output options below).
‘Enhanced power measurement’
module provides all the functions of
the ‘Basic’ unit but also includes full power monitoring Instrumentation and powerful auto-sync functions as standard. The inclusion of auto-sync now allows the OEM to offer the choice of clean break or ‘Bumpless’ no break transfers to and from the gen-set. No need for complex sync panels etc. Simply use the 555 Power measurement module and interface to the engine governor
and AVR.(No break transfer using the 555 module requires Connecting to a suitable electronic governor and AVR.)
Load control versions can be used to export a fixed amount of power to the load while in parallel with the mains, with soft transfer to and from the genset. Optional RS232 port allows comprehensive remote control and monitoring. RS232 provides modem link to PC via PSTN line or GSM network (with suitable modem). Uniquely, the module supplies DC power to the modem ensuring integrity of link during loss of mains and engine starting.
The module can also signal Engineers via the cell phone network using the GSM SMS
messaging system to advise of
system alarms. Optional RS485 ‘Modbus’ output. Using industry standard communication protocol allows full system integration into new and existing building management and control schemes.
