Description: This is a working pull as the application (surgical center) required an extensive remote notification panel for NFPA compliance. This is primarily a generator controller that will handle starting and stopping of a diesel or natural gas generator set. In concept an Automatic transfer switch would detect utility loss and close a two wire start to the generator controller (being sold) The generator controller will engage the run circuit with relay (fuel pump, ignition ECM, electronic governor controller ) then (optional glow plugs) and then start the engine. Once the engine is running it has oil pressure, coolant temperature , engine speed monitoring (for Hz) , voltage sensing and current monitoring. It keeps track of engine run hours as well as logging alarms , displaying engine and generator reading. When these parameters run out of safe range the controller has programmable outputs to alert of failures. Thomson discontinued the MEC-20 years ago, but there are plenty of generators out there still using it (Baldor is one) . If you have a generator and the controls are very difficult to work with or have completely failed leaving you without a generator this particular setup is suitable for most generators with a controller independent voltage regulator and throttle actuator. Unlike other controllers this one can be setup without a PC and fully configured with the push buttons on the front. Included in the listing: -Working MEC-20 controller -Oil pressure sensor. (Resistance based) -Coolant temp sensor (resistance based signal to ground) - Two Bosch style 12v relays (One for run circuit and one to engage starter solenoid signal to ground) -12vdc starter solenoid -Three current transformers. (1&3 are used for 120/240) - Simple wiring bus to terminate battery charger, E-Stop and two wire start leads . -Misc colored wiring for creating a custom harness. -schematics depicting how to connect wires. -USB thumb drive with full OEM manufacturing documentation detailing all info needed to install this controller. Other documents helpful for setting up a generators. Condition and disclosures: -All passwords default and in documentation. -The finish on the front of the controller has peeling clear coat. -used with run hours in the mid 400's -LCD display has a few thin lines of omitted display (easily still readable) -Currently configured as three phase 120/208 60hz voltage. -Magnetic pickup off of flywheel is not included (most generators have this installed from the factory) -annunciator communication port condition is unknown. You can setup digital outputs to inform of alarms and conditions. -The relays, solenoid and wiring are new. If you need 24v head over to Napa. What your generator should have. -governor control system that is mechanical or energized 12v to run and maintain correct Hz . -Automatic voltage regulator (runs independent and gets operating voltage off alternator ends. (No Kohler optical generator end will not work) - Magnetic pickup (two lead) it would be helpful if you know how many flywheel teeth on your engine, if not there is a formula on a tech sheet. This signal needs to go to the controller. -If your engine requires manual choke it needs to be changed to electronic. -Glow plug output may require an additional relay as the outputs can't carry high current loads. In addition to being in a generator application this controller can also be used in an application where you need to start a stationary engine (irrigation pump, chipper engine, carpet cleaning.) Any application where you want to close a switch and have it start an engine safely and reliably run it. Thanks for looking , hopefully this description covers your questions about this controller. I'm happy to answer any questions, I also have a lot of other generator controllers to put on eBay.
