• Adjustable from 0 - 100%
• DC output 1 - 5 VDC
• Knob for manual control
• Screw lock for knob

The SELCO B9300 is intended for use together with the T4800 Load Sharer or the T4300 Load Sharer, when a generator is operating in parallel with the grid.

The T4800 will adjust the power to be delivered by the generator according to the setting of the B9300, which is adjustable from 0 to 100 percent. A finger screw is provided to lock the dial.

The B9300 is flush mounted with measurements of 96 x 96 x 75 mm (H x W x D).

• Sealed wire wound potentiometer
• Built-in dust seal
• Low speed motor for accurate control
• High drive capability
• Resistance from 100 to 10 kΩ
• Large size knob for manual control
• LED indication of turn direction
• Optional programmable RPM
• AC or DC supply

The SELCO E7800 Motorised Potentiometer is typically used as an interface between increase/decrease relay contacts (or push buttons) and a device requiring control by an external potentiometer (e.g. the speed trim of an electronic governor).

All three wires of the potentiometer are directly accessible on external connection terminals, thus providing the best possible flexibility for almost any application.

A special version of the E7800 with DC voltage output is also available. The DC output voltage follows the position of the potentiometer. The design of the E7800 ensures that the potentiometer will "remember" its position although supply is lost.

• Reads engine speed from AC voltage
• Tacho system for M2000 and M2100
• Square wave speed output
• Nominal voltage output

The SELCO M0500 is an accessory unit for the SELCO M2000 Engine Controller and the M2100 Emergency Controller.

The M0500 reads the engine speed from the frequency of the generator output voltage. The speed reading is converted to a square wave signal and this signal is provided on a dedicated output.

• Stand alone engine protection
• Provides complete redundancy in combination with M2000
• Can be mounted on the rear side of the M2000
• Complies with even the strictest Marine Classification requirements

The M0600 provides protection for any type of diesel or gas engine.

The unit has inputs for over speed, low oil pressure and a user defined input which can be used to monitor e.g. high water temperature. The M0600 has an input to indicate that the engine is running and another input to indicate that the engine is in the process of being halted.

• Engine start/stop
• Engine protection
• Direct input for magnetic pick-up
• RS232 interface for PC based configuration
• RS485 interface for communication
• 50 hour burn-in before test
• Certified for marine use

The SELCO M2000 Engine Controller will control and protect any industrial combustion engine, which accepts discreet I/O signals for control of the crank, the fuel valve and the stop solonoid (if applicable). The engine must be able to supply potential free contacts for starter disengagement and over speed alarm (normally done through a standard tacho relay). The M2000 is typically used as an engine controller for diesel or gas driven generator sets.

• Automatic Mains Failure (AMF)
• Engine protection
• Highly reliable
• 50 hour burn-in before test
• Certified for marine use

The SELCO M2100 Emergency Controller will control and protect any stand-alone generator driven by a combustion engine. The M2100 performs the role of an AMF system (Automatic Mains Failure), as it continuously monitors the main supply for possible disruptions.

An external voltage relay (e.g. the T3100 Voltage Relay or the T3300 Voltage Relay (three phase)) will activate the M2100 in case the main supply is lost. A programmable start delay prevents unnecessary start ups due to short term power glitches. The M2100 can be programmed to perform multiple start attempts with intermediate rest times.
