What to do if Thermo Scientific NCS-3500RS can't start pump while alarm is on?
If an alarm has occurred, such as a leak alarm, you must acknowledge the alarm before restarting the pump flow. For example, perform the AlarmOff command in Chromeleon.
Why has the pressure fallen below the lower limit in Thermo Scientific Laboratory Equipment?
If the pressure has fallen below the lower limit, it may be because the solvent reservoirs are empty. Fill the reservoirs and purge the pump. Also, check the solvent supply line for air bubbles, inspect the filter frits, and purge the system.
What does it mean when the LED flashes red on Thermo Scientific NCS-3500RS Laboratory Equipment?
If the LED flashes red, it indicates that the pistons are not in the correct position for normal operation, possibly after piston replacement, or an error occurred during internal maintenance. To resolve this: 1. Open the purge valve. 2. Perform the Dock Pistons command. 3. Close the purge valve.
Why calibration procedure failed in Thermo Scientific NCS-3500RS Laboratory Equipment?
If the calibration procedure fails because pressure cannot be built up and held, consider the following possible causes: * Ensure the purge valves are closed. * Verify that the fitting plug is correctly installed. * Check for leaks in the system. Find and eliminate any leaks, tightening any loose connections. Afterward, repeat the command.
What to do if Thermo Scientific Laboratory Equipment cannot pressurize the system?
If pressure buildup fails, the possible causes and solutions are: * Check for air bubbles in the system and purge the pump. * If the inlet valve is defective, replace the valve cartridge. * If the solvent reservoir is empty, fill it and then purge the pump.
Why Thermo Scientific NCS-3500RS cannot regulate flow?
If the NC pump cannot build up sufficient pressure to deliver the selected flow rate, consider these potential causes and solutions: * Ensure the solvent reservoir is full. * Purge the pump to remove any trapped air. * Check for leaks in the system; find and eliminate any sources of leakage, tightening connections as needed. * Replace the frit in the solvent supply line filter if it's clogged. * Replace the inlet valve cartridge if it is blocked.
