Control method | 1. Emergency stop start control: After pressing the emergency stop button, the device will automatically pull the load based on the current voltage; 2. Fan maintenance button: For daily maintenance, manually start the fan and observe if it is working properly; 3. Short circuit start at the dry output point: Short circuit start signal at the dry output point, and the device will automatically load based on the current voltage Load, can be connected to normally open dry contact signals such as smoke alarm and over temperature alarm; 4. Communication control start stop: By writing a start stop signal through communication, the device will automatically start loading based on the current voltage Load, while monitoring the current voltage, current, load gear feedback, equipment status, and other information of the equipment; 5. When the equipment starts, close the 1-4 circuit breakers in sequence, and when the current voltage is detected to be lower than the set value, hold the After 1 minute, automatically switch to the next set of test circuits. 6. Operation priority, emergency stop button operation>dry contact control>remote communication control. |

Temperature alarm | The device has a level 2 temperature alarm. The first level temperature alarm only sounds a buzzer, while the second level temperature alarm buzzer sounds and unloads the load, and outputs a dry node signal to the outside. |
Smoke temperature alarm | A smoke temperature detector is installed on the top of the cabinet, which can provide smoke alarm and output alarm dry node signals to the outside |
Short circuit protection | equipped with incoming circuit breaker (for live operation) |
Fan interlocking | Without starting the fan, the load cannot be pulled. |
Fan phase sequence protection | Built in phase sequence conversion switch, when voltage phase sequence error is detected, the fan can also start in the normal direction. |
Fan air volume protection | The device is equipped with a built-in air pressure switch. When insufficient fan air pressure is detected, the load is stopped and fed back to the upper computer. |
Low temperature start | The control room inside the load cabinet is relatively isolated from the outside, and a heater is installed to meet the starting condition of low temperature -40 ℃ |
Grounding protection | In order to avoid the risk of electric shock when the load is working, the load cabinet is equipped with a dedicated grounding protection terminal. |
Withstand voltage characteristics | Resistance to ground: AC3KV, 50Hz, 1 minute, no breakdown, no flying fox |
Insulation characteristics | DC1KV, insulation greater than 10MΩ |
