The following is a HW-A-1020 type DC speed regulator, connection method and use:

Connection: HW-A-1020 type governor has three terminals, please refer to specific wiring method described in the text below

(1)黑线:接直流电源负极或 使用电瓶时接电瓶打铁,

Black: (1) connected with the negative electrode of the DC power supply or battery connected battery blacksmith,

(2)红线:接直流电源正及或 使用电瓶时接电瓶正极,

(2) the red line: connected with DC power supply are and or the use of battery connected battery cathode,

(3)电机正极:接直流电源正极或 使用电瓶时接电瓶正极,

(3) the motor positive: the positive terminal of the DC power supply or battery connected battery cathode,

(4)蓝线:接直流电机负极

(4) the blue line: DC motor negative

Instructions for use:

接线正确后、通电顺时针调节旋扭、这时可听见或感到调速开关内部有清脆的声音、这时证明内部开关已打开

The wiring is correct, after electrify clockwise adjustment knob, then you can hear or feel the speed switch within the crisp sound, then that the internal switch is opened

随着旋扭的角度不断的加大控制电机转速不断的加速、当把旋扭旋到底时电机的速度也达到最高速.

With the increase of motor speed control continued to accelerate, when the knob rotation in the end when the motor speed to achieve the high speed rotating angle constant

注意:正负极切勿接反

Note: do not reverse polarity
