April 5, 2026: LEMON Manuals is launched! Read the announcement.

Signal Specification

All the values given below are between the terminals stated in column 1 and terminal #1 in column 2 (signal ground). This applies unless otherwise indicated in brackets.

NOTE: It is important to connect the breakout box and check the ground terminals before taking readings.

There may be several connections and connectors between the control module and components.

U=	DC voltage in volts (V)	U_AC =	AC voltage in volts (V)
U_bat =	Battery voltage (V)	f =	Frequency in Hertz (Hz)
U_low =	Voltage approximately 0 V	t =	Time in seconds
PWM =	Pulse width modulated signal as a %	-	-
