Oil pressure detection: For the prime mover equipped with a pressure relay, use a pressure calibrator to detect the set value and check whether the control screen is open and shut down. The prime mover equipped with a monitor first performs a self check, and then removes the signal input line to check whether the control screen is open and shut down.

油温、水温检测：将模拟检测好的传感器与传感器导线连接，把传感器放在排气管上加温，检测是否在设定值上分闸停机。

Oil temperature and water temperature detection: Connect the simulated detected sensor to the sensor wire, place the sensor on the exhaust pipe for heating, and detect whether it is shut down at the set value.

检查气源应急阀门、电磁阀是否可靠。

Check if the emergency valve and solenoid valve of the air source are reliable.

减掉负载，合上短路器开关，把转速开关设置到额定转速位置，然后调整2301A速度控制器的额定转速电位器，缓慢顺时针旋转直机组在设定值报警分闸、超速停机为止，然后将额定转速电位器逆时针复位到原来的位置。

Reduce the load, close the breaker switch, set the speed switch to the rated speed position, then adjust the rated speed potentiometer of the 2301A speed controller, slowly rotate clockwise until the unit is at the set value for alarm opening and overspeed shutdown, and then reset the rated speed potentiometer counterclockwise to the original position.
