What to do if different probes in the same solution show different pH readings on GE Xcellerex XDUO?
If different probes in the same solution show different pH readings: * Calibrate pH probes before use, because one of the pH probes may not be calibrated. * Replace the probe, because the probe may be at the end of its life cycle.
What to do if load cell is not functioning as expected on GE Mixer?
If the load cell is not functioning as expected, consider the following: * Ensure the load cell is properly connected. * Contact the metrology department to perform a cornering test to determine if a load cell has failed. * Verify that there are no physical obstructions blocking the load cell's motion. * Disengage the jacking bolt. Note that weight measurements are inaccurate if the mixer was filled while the jacking bolt was engaged. * Contact your GE representative if you suspect the configuration on the load cell transmitter is incorrect or corrupt. * Schedule a calibration of the load cells.
What to do if weight monitoring error occurs on GE Xcellerex XDUO?
If you encounter a weight monitoring error, such as a weight display outside the operational range or a weight alarm triggered when the mixer weight is within range, consider the following: * Contact the metrology department to perform a cornering test to determine if a load cell has failed. * Check for any physical obstructions that may be hindering the load cell's motion. Ensure the mixer vessel legs are free. * Disengage the jacking bolt. Note that inaccurate weight measurements can occur if the mixer was filled while the jacking bolt was engaged. * Contact your GE representative if you suspect the weight transmitter configuration is incorrect or corrupt.
What to do if agitator does not start on FlexFactory controlled GE Xcellerex XDUO?
If the agitator does not start on a FlexFactory controlled mixer: * Enable the agitator. * Tap RESET on the local control software screen and start the agitator when the system has been restarted after emergency shutdown. Note: The agitator cannot be started while the system is in the state E-STOP. * If the system is in Manual mode, set the system to Auto mode and specify the setpoint. Note: When the system is in Manual mode the setpoint is ignored.
Why is variable frequency drive (VFD) not functioning as expected in GE Xcellerex XDUO?
The variable frequency drive (VFD) might not be functioning as expected due to: * The motor being overloaded. Acknowledge the agitator fault and attempt to restart the motor. If the error persists, contact GE for service. * The power cable not being connected. Connect the power cable. * The drive is broken. Contact your GE representative to replace the drive.
What to do if agitator motor cannot be started on GE Mixer?
If the agitator motor cannot be started, check the following: * Ensure the power switch on the I/O Cabinet is in the I ON position. * Verify the power cable is connected. * If the issue persists, the drive may be broken, and you should contact your GE representative to replace it.
What to do if the tubing is moving in the pump head of GE Xcellerex XDUO Mixer?
If the tubing is moving in the pump head: * Tighten the tubing clamps in the pump head, as the tubing clamps in the pump head may not be properly set for the installed tubing. * Adjust the biting elements using the thumbscrews on the lower right and left sides of the pump, as the tubing is not fastened in the pump head (pump model 313).
What to do if an error code is shown on the VFD display of GE Xcellerex XDUO Mixer?
Refer to the VFD manufacturer's manual for error code clarification. If the problem cannot be solved on site, contact your GE representative for help.
What to do if pH sensor changes are very slow for the application on GE Xcellerex XDUO?
If pH sensor changes are very slow and pH control is not rapid enough for the application, do a study to find the best tuning parameters for your system and available reagents, as the tuning parameters or the concentration of the applied acid or base may not be sufficient.
What to do if the pump is not turning on GE Xcellerex XDUO Mixer?
If the pump is not turning: * Verify that the cause of the E-STOP condition is eliminated, and clear the E-STOP. Try to use the pumps again. * Clear the interlock condition.
