The Eco-governor does away with the need for the parts shown in Table 2-5 that are used for mechanical
governors:
Table 2-5 List of electrical parts not required for the Eco-governor
Part name
Safety relay
Stop solenoid
Timer
Relay
Diode
Timer
QHS controller
Notes: A timer for preheat lamp is required when the preheat function is used (see 6 "Starting aid").
Commercially available electrical parts used instead of Yanmar genuine parts must meet the minimum
requirements specified in Table 2-6. Failure to meet these requirements may affect the engine performance
or cause malfunction of the E-ECU.

• Sensor output voltage: 0 – 5V (0.7 V Min.. and 3.0 V Max. as standard)
• Resistive potentiometer (2.0 kΩ Min..) or thru-hole potentiometer
• When a thru-hole potentiometer is used, its current consumption must not
exceed 5 V/10 mA.
• When the sensor input voltage is lower than 0.2 V or higher than 4.6 V, the
sensor is assumed to fail. The input voltage therefore requires to be held
within a range of 0.5 – 4.0 V (10 – 80% of the actual effective electrical travel).
