Deep Sea Electronics PLC The DSE704 is an Automatic Mains Failure module with generator monitoring, protection and start facilities. It utilises advanced surface mount construction techniques to provide a compact yet highly specified module. Operation of the module is via three pushbuttons mounted on the front panel with STOP, MANUAL and AUTO positions. Selection of the ‘Auto’ mode is confirmed by LED indicator, and monitors the incoming mains supply (3 phase or single phase). Should the incoming AC mains supply fall below a configurable pre-set limit (180V default), the generator will be started, and load transferred to the gen-set. When the AC mains supply returns to within limits, the module will wait for a configurable, pre-set stabilisation period, and then transfer load back to the mains. The engine will be instructed to stop after a cool-down period. The module’s microprocessor provides a comprehensive list of timers and functions, and access to the settings is via a small Configuration Switch on the rear of the module. Parameter settings can be adjusted using the front panel pushbuttons once in Configuration Mode.

Deep Sea Electronics PLC 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 (detailed right) 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 gen-set. 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. The 500 series modules have been designed for front panel mounting. The module is fitted into the cut-out with the fixing clips removed. These are then fitted from the rear. Connection is via locking plug and socket. Dimensions: 192mm x 144mm x 138mm 7.6’’x 5.7’ x 5.5’’
