How to troubleshoot a dead display on an Oval EL1810?
If the Oval Controller display is dead, first, inspect the fuse. Then, check the supply voltage, ensuring it is between 85 and 264VAC for the AC version. It could also indicate a fault in the controller.
What to do if the Oval EL1810 fails to perform batch operation at the setpoint?
If the Oval Controller fails to perform the batch operation at the setpoint, verify that the valve control signals SV and MV actuate when the target batch quantity is reached. Also, check if the LCD SV goes out and the LCD END comes on when the target batch quantity is reached. It may indicate a fault in the controller.
What to do if the valve fails to respond to START key depression on the Oval Controller?
If the valve fails to respond to START key depression on the Oval Controller, check if terminals 19 and 20 (remote control input Stop, From “b” contact) on the terminal block are shorted. Also, check if valve control signals SV and MV actuate properly. Ensure the batch is not set to 0, and verify the valve control signal wiring and supply voltage are correct. Confirm that valve operating and control pressure settings are correct, and ensure that the batch process has been reset (Alarm reset, end-of-batch output reset, etc.).
Why is the remote control inoperative on my Oval Controller?
If remote control is inoperative on the Oval Controller, first determine if it is possible to control with front panel control keys. Then, check if the remote control circuitry is wired correctly. It could also be a fault in the controller.
Why does the valve operate but the total counter fails to count on the Oval EL1810 Controller?
If the valve operates but the total counter fails to count on the Oval Controller, determine if a flowrate signal is coming in from the flowmeter and if the incoming flowrate signal is within the acceptable frequency range of response. It could be due to incorrect wiring or an open in the cable, or a fault in the flowmeter itself or in the pulse generator.
