If the ECU is not available, you can set a [PICKUP / W RATIO]  and connect a pick-up or the ‘W’ terminal of the engine charger alternator. The ‘ratio’ has a range of 10.0 up to 500.0. By setting a ratio, the Be126 will enable the PICK-UP failure monitoring.

NOMINAL SPEED

                    1500

(100-4000 R.P.M.)

In ‘AUTO’ mode, the engine runs at [IDLE SPEED] then, after the [IDLE TIME], it will reach the nominal speed. During [IDLE TIME] the Be126 disables the JB-2 output. You can connect an auxiliary relay to control a speed governor. The [NOMINAL SPEED] setting is mandatory when you connect the Be126 to an ECU.
