What to do if Varian 380-LC Security Sensors detect a leak inside the unit?
If the Varian Security Sensors detect a leak inside the unit, it means that solvent vapor has been detected. The suggested solution is to stop the pump.
What should I do if the Varian 380-LC' liquid leak sensor has detected liquid in the drip tray?
If the liquid leak sensor in your Varian Security Sensors has detected liquid in the drip tray, it indicates liquid is in the base of the unit. You should stop the pump and investigate the cause.
Why is there baseline noise in Varian Security Sensors and how to fix it?
Baseline noise in Varian Security Sensors can occur if the particle plume is not sufficiently dried in the evaporator tube. To resolve this, increase the temperature of the evaporator by 10° intervals until the noise is acceptable.
Why is there baseline noise in Varian Security Sensors and how can I resolve it?
Baseline noise in Varian Security Sensors can be caused by poor nebulisation of solvent. Increasing the gas flow rate should resolve this issue.
Why is there baseline noise in Varian Security Sensors due to pump pulsations, and what is the solution?
Baseline noise in Varian Security Sensors can be caused by pump pulsations, especially in microbore applications where low flow rates are used. To fix this, increase the back pressure on the pump by fitting a back pressure regulator between the pump and the injection valve.
What causes a Fan Driver IC Thermal Shutdown in Varian 380-LC?
A Fan Driver IC Thermal Shutdown in Varian Security Sensors can be caused by a fault with the circuitry, wires, or the fan itself. No specific solution is provided.
Why did the fan stop in Varian 380-LC?
The fan in Varian Security Sensors may have stopped due to a fault with the circuitry, wires, or the fan itself. No specific solution is provided.
Why is the air temperature less than or equal to 10°C inside the Varian Security Sensors enclosure?
If the air temperature inside the Varian Security Sensors enclosure is less than or equal to 10°C, it is because the environmental temperature is too cold. No specific solution is provided.
Why is the air temperature greater than 40°C inside the Varian Security Sensors enclosure?
If the air temperature inside the Varian Security Sensors enclosure is greater than 40°C, it is because the environmental temperature is too hot. No specific solution is provided.
