safety warning:
Read all safety warnings before installing this equipment
1. Do not install, dismantle or rewire when the power is on;
2. Ask professional electrical technicians to install, adjust and maintain this equipment;
3. Please use a non-metallic screwdriver to adjust the trimmer potentiometer. If you operate this governor with power on, please wear personal protective equipment and insulated tools;
4. Reduce fire, electric shock or explosion by using proper grounding, overcurrent protection devices, and thermal protection devices;
5. Protect the governor from dust, moisture and accidental contact;
6. Install the governor away from the heat source, and operate the governor within the specified ambient working temperature range;
7. Prevent loose connections by avoiding excessive vibration of the governor;
8. The governor can be installed horizontally or vertically;
9. The shell should be grounded;
10. When the continuous armature current is higher than 5 amps, an additional heat sink is required, and thermal grease is used between the case and the surface of the heat sink to achieve optimal heat transfer;

10. Working environment: °;
11.;
12. It is suitable for permanent magnet DC brush motor with driving power not greater than 1000W;
2. Size
Dimensions: L*W*H=135*105*35mm
3. Wiring
1. Power supply
Connect the AC power line with a 10A fuse in series and connect it to terminals L1 and L2 through a double-pole switch;
2. Motor
Connect the DC motor wires to terminals A1 and A2, if the motor runs in the opposite direction, switch A1 and A2 after turning off the AC power;
3. Speed signal
Connect a 2W10KΩ potentiometer between V+ SIG COM to adjust the speed, and the center of the potentiometer is connected to SIG;
If an analog signal is used, connect the negative pole to COM, and the signal terminal to SIG. Note that the signal must be isolated;
4. Start/stop control switch
EN and COM are the start and stop control terminals, and whether it is turned on or off depends on the jumper J4; when J4 is turned on, the motor runs when EN and COM are turned on, and when it is turned off, the motor stops; when J4 is turned off , when EN and COM are connected, the motor stops, and when they are disconnected, the motor runs;
5. Direction control switch
When DIR and COM are connected, the motor runs forward, and when it is disconnected, it runs reversely;
4.Jumper settings
1. J1: armature voltage selection, when off, 0-180V, when on, 0-90V;
2. J2 speed or torque mode selection, it is speed mode when it is off, and it is torque mode when it is on;
3. J3 regeneration function selection, regenerative braking when disconnected, natural stop when connected;
4. J4 start/stop switch selection,
5. J5 current limit selection, if the motor current is less than 2.5A, short circuit; if the motor current is greater than 2.5A, disconnect;
Note: Be sure to confirm that the AC power is disconnected when setting;
5. Indicator lights
1. Green light
Steady on: enable;
Flash once: disabled;
2. Red light
Steady on: the armature current reaches the set current;
6. Function description of potentiometer
1. MAX SP: Adjust the maximum output voltage, decrease counterclockwise;
2. OFFSET: Offset adjustment, when the minimum speed needs to be set, adjust this potentiometer;
3. CL: Adjust the maximum output current, decrease counterclockwise;
4. IR: Torque compensation function: increase clockwise, decrease counterclockwise;
