Why is the ALARM LED on in my NAiS FP1 Controller?
If the ALARM LED is ON in your NAiS Controller, it might be due to an excessively long program execution time. Review your program and check for instructions like JP or LOOP that may prevent a scan from completing.
What to do if the “PROTECT ERROR” is displayed on NAiS FP1 Controller?
If you're seeing a “PROTECT ERROR” displayed, it could be due to a memory unit (EPROM) or master memory unit (EEPROM) being installed. Remove the memory unit (EPROM) or the master memory unit (EEPROM) from the programmable controller. Alternatively, a password might be set for the programmable controller. In that case, change the password setting using a programming tool.
How to fix Total-check error on NAiS FP1 Controller?
A total-check error in your NAiS Controller indicates a problem with your program. Here's what to check: * Ensure instructions are correctly programmed, referring to their descriptions. * Correct the program to avoid using the same relay for two or more OT instructions. * Ensure that all paired instructions are present. * Verify that the operand for the instruction is within the range set in the system register, using a FP Programmer II (OP50) or NPST-GR Software (1. SYSTEM REGISTER in the PLC CONFIGURATION). * Confirm that the instruction is programmed in the correct position, referring to its description. * Use the correct operand for the instruction, referring to its description.
What to do when all LEDs are OFF on NAiS FP1?
If all LEDs are OFF on your NAiS Controller, the first thing to check is the power supply wiring.
What does “PLC = COMM. ERR” mean on NAiS Controller and how to fix it?
If you're seeing “PLC = COMM. ERR” on the NPST-GR screen, verify that the baud rate settings of the FP1 and NPST-GR are the same.
What causes Battery Error on NAiS FP1 Controller?
If you encounter a Battery Error (Self-diagnostic Error) with your NAiS Controller, it means that the voltage of the backup battery is low or the backup battery is disconnected. Replace the backup battery, referring to the page 216.
