![]() The TM7 has the ability to totally isolate the starting battery after shutdown. When used in association with an inexpensive slave relay, output B is ideal for controlling heavy decompression solenoids or electric stopping circuits. Or Stopping Option B : where the power is OFF while the engine runs, then ON for 15 seconds in an emergency. Either Stopping Option A : where the power is ON while the engine runs and then OFF in an emergency (ideal for controlling fuel solenoids). The TM7 is flexible enough to stop most engines. This allows the operator to know the engine functioned correctly during its last run. When the TM7 is started whatever function last stopped the engine will display. Bypass time can be programmed by the operator in 10 second increments from 1 second to 4 minutes (Factory set at 10 seconds). When the engine starts the TM7 has a bypass mode to allow the engine and pump pressures to stabilize before the protection circuit starts. The TM7 has a spare stopping input used for any purpose that switches to ground on a fault, such as Fan belt switches on air cooled engines, Murphy high-low water pressure switches on water pumps or float switches (see in pricing if you require a Murphy water pressure switch). If your engine does not have a oil light, a standard car type sender needs to be fitted (normally closed contacts / open on pressure). The low oil pressure wire is simply tagged onto the engines existing oil light sender, if the light comes on the engine will stop. If the engine temperature goes higher than the alarm temperature set into the TM7 by the operator, the engine will stop ('Easy Fit' sensor supplied). TM7's Run timer can be set to stop the engine ![]()
