    1、the over temperature alarm: the sample area of the sensor is arranged in the channel and over temperature protection device, equipped with ultra temperature protection device in the operation panel, when the test area temperature exceeds the set temperature allowed on the panel, equipment shutdown and alarm, must set TH have the highest temperature 10 DEG C higher equipment can work.

    2、sample over temperature protection: when the sample area temperature exceeds the protective temperature set by the controller, the equipment will stop and alarm, and must be out of order, and the equipment can run normally after the reset. Sample over temperature protection, upper limit protection, lower limit protection, users can arbitrarily set according to need.

    3、fan overheating alarm: when the fan coil overheating, equipment downtime and alarm, must be troubleshooting, the equipment is allowed to resume operation.

    4、fan over flow alarm: when the fan current exceeds the allowable value, the equipment will stop and alarm, and the equipment must be allowed to resume normal operation after the overcurrent fault has been completed.

    5、circulating cooling water shortage alarm: when the cooling water circulation system water pressure is insufficient, the equipment stops and alarm, must be troubleshooting, and reset equipment can return to normal operation.

    6、refrigeration compressor overheating alarm: when the compressor coil overheating, line power supply is not normal, the equipment shut down and alarm, must be troubleshooting, the equipment can be restored to normal operation.

    7、refrigeration compressor overpressure alarm: when the refrigerant system refrigerant pressure exceeds the set value, the equipment shut down and alarm, must be troubleshooting, and manual reset, equipment can return to normal operation.

    8、the power supply phase, phase sequence alarm: when the external power supply equipment phase, phase changes, the equipment downtime and alarm, must be troubleshooting, the equipment can be restored to normal operation.
