  The red ALARM LED on your SMC Networks Laboratory Equipment might be triggered by several factors. It could be due to high-level electrical noise affecting the power supply, ground, or signal lines; try moving the equipment to a less noisy environment and restarting it. Also, verify that the power supply voltage is within the correct range (100-240VAC). Ensure that the bath liquid is not excessively heated and that the water level is adequate. Check that the facility water supply has the appropriate flow rate. If the water level in the bath is low, increase it.

  If the red ALARM LED is illuminated on your SMC Networks Laboratory Equipment, several issues could be the cause. Begin by checking the air vents to ensure they are not blocked. Also, confirm that the facility water flow rate is within the specified range of 3-7L/min and the temperature is between 10-35°C. The ambient temperature should also be within 10-35°C and humidity within 35-85%. Additionally, verify that an instantaneous power supply cutoff has not occurred frequently.

  To address a red ALARM LED on your SMC Networks Laboratory Equipment, start by inspecting the float for any trapped foreign matter; clean the tank if necessary or consider replacing the level switch. If there's a possibility of contact failure with the thermostat or level switch connector, try unplugging and re-plugging the connector. Also, make sure that the level switch is mounted vertically. If raising the float and supplying power doesn't resolve the issue, replace the level switch.

  A red ALARM LED on your SMC Networks Laboratory Equipment can indicate several problems. The internal temperature of the product may be too high, leading to the DC power supply not working correctly; ensure the air vents are not plugged. Also, the circuit protector of the product or the GFCI installed on the primary side may have tripped. Confirm that the bath liquid is not excessively heated.

  The red ALARM LED on your SMC Networks Laboratory Equipment can be triggered by a few things. High-level electric noise on the power supply, ground, or signal lines can cause it; try moving the product to a less noisy environment. Also, an incorrect power supply voltage to the system can be a reason; make sure it's 100~240VAC. Additionally, check if foreign matter is caught in the float, causing it to fail.
