What to do if my Waters 2545 Binary Gradient Module Control Unit display is blank?
If the display is blank, first, ensure the unit is powered on. If it fails to power on, power it off, and then on again. If the problem continues, call Waters Technical Service. Also, check the contrast settings by pressing the contrast button, as it may be set too dark.
How to fix erratic flow rate or pressures in Waters 2545 Binary Gradient Module?
Erratic flow rate or pressures can stem from several causes. Start by priming the binary gradient module to eliminate any air bubbles in the pump head. Then, inspect and clean or replace the inlet check valves if they are dirty. Ensure the prime/vent valve is fully closed and not leaking; rebuild it if necessary. Also, check the solvent reservoir filter for any blockages and clean or replace it. Finally, a leaking plunger seal could be the culprit, in which case, replace the plunger seal assembly.
What to do if my Waters Control Unit does not power on?
If the unit doesn't power on, first verify that the power cord is securely connected. Next, check the power outlet to ensure it's providing power. Lastly, inspect the power supply fuses and replace them if they are blown or missing.
What to do if Waters 2545 Binary Gradient Module front panel software is locked up?
If the front panel software locks up, power the unit off and then on again. If the problem persists, contact Waters Technical Service for assistance, as this could indicate a software or power line issue.
