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 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 pH is not coming to equilibrium on GE Xcellerex XDUO Mixer?
If the pH is not reaching equilibrium even when the pumps are running, consider these possible causes and solutions: * Ensure the deadband is not set to 0, as pH control requires a deadband to prevent alternating introduction of acid and base. Define an appropriate deadband value for your process. * Check if the acid/base supply is empty and fill it if necessary. * Prime the pumps to ensure they are functioning correctly. * Inspect the feed lines for kinks or clamps and free them to ensure proper flow. * Conduct a study to verify the control parameters, considering factors like media quantity, pump type, acid and base concentration, mapping strategy, media buffering capability, and mixing of vessel contents.
What to do if tubing is worn out on GE Xcellerex XDUO Mixer?
All tubing used in the pumps will wear out with use over time. Move the section of worn out tubing to the left or right. Use only tubing rated for use in peristaltic pump head.
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.
What to do if pH sensor changes are very slow on GE Xcellerex XDUO Mixer?
If pH sensor changes are very slow, and two sensors change their readings at different rates, the pH sensor may need cleaning. If available, switch the input to the second pH channel. Keep probes clean between uses, and clean them with a solution designed to maintain their properties. Replace probes regularly.
What to do if temperature monitoring is not working as expected on GE Mixer?
If temperature monitoring is not working as expected: * Switch to the second input of the temperature probe if possible. If the second input is not present or is not working, replace the probe. * Ensure the temperature probe is inserted into the thermowell.
What to do if the agitator does not start on GE Mixer?
If the agitator does not start, consider the following: * Check if the Min Weight interlock is active. Check the weight of the disposable bag. * If the system is in the state of E- STOP, tap RESET on the local control software home 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.
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.
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.
