Why is Pentair Goyen Precision P1 system not recognized on the plant SCADA system?
If your Pentair Control Unit system isn't recognized by the plant SCADA system, it might be because Modbus communications is turned off in the menu. To resolve this, enter the menu and ensure the network is assigned an address, instead of being set to off. Also, verify that the controller's network address matches the address assigned at the DCS level.
How to fix valves on multiple expansion boards firing simultaneously in Pentair Goyen Precision P1?
If valves on multiple expansion boards of your Pentair Control Unit are firing simultaneously, and the outputs correspond to each other, it indicates that two or more expansion cards are set with the same address. To fix this, check that each output is assigned a unique address.
What to do if Pentair Control Unit P2 does not go into cleaning mode and shows 'Stopped (FAN)'?
If P2 on your Pentair Control Unit doesn't go into cleaning mode on startup and the display shows ‘Stopped (FAN)’, with valves not pulsing, it could be due to closed fan contacts on the baseboard. Check the wiring to the fan contacts, ensuring they are open if a fan or another circuit breaker isn't connected. If a fan is connected, confirm that the contacts at the fan are normally open and verify the wiring.
What to do if Pentair Control Unit P2 does not go into cleaning mode and shows 'Stopped (dP)'?
If P2 on your Pentair Control Unit doesn't enter cleaning mode at startup and the display reads ‘Stopped (dP)’, with valves not firing, it means P2 is waiting for the differential pressure to rise above the factory preset Remote Stop value or to ‘Hardwired’. To address this, access the menu and either set the remote stop dP to your preferred value or to ‘Hardwired’, or wait for the dP to increase.
What to do if Pentair Control Unit P2 does not go into cleaning mode and shows 'Precoating'?
If P2 on your Pentair Control Unit doesn't go into cleaning mode on startup and the display shows ‘Precoating’, it indicates that P2 is waiting for the differential pressure to rise. You can either enter the menu and set Precoating to off, or, if set above the factory preset Precoating value, wait for the differential pressure to rise.
Why are expansion cards not pulsing sequentially in Pentair Control Unit?
If expansion cards on your Pentair Control Unit aren't pulsing sequentially and Pattern cleaning mode is off, it's likely because the expansion card addresses haven't been assigned in sequential order. To resolve this, re-assign the expansion card addresses in numerical order.
What to do if Pentair Goyen Precision P1 system does not power up?
If your Pentair Control Unit system fails to power up, the power LED remains off, and expansion cards or solenoids aren't detected, start by checking the power connection to the baseboard. Ensure the wiring to the socket aligns with the manual's instructions and that the power supply meets the controller's minimum requirements. Also, verify the ribbon cable to the P1 or P2 interface is secure. Replace any blown fuses. If problems persist, it could be a defective on-board power supply or interface, requiring you to contact your supplier. Confirm that cabling between expansion cards and the baseboard is correct, replacing any broken cables. Ensure the common terminals between each bank of solenoids are linked and returned to the common terminal on the relevant baseboard or expansion card, an...
