How to fix ERROR 10 on Spirax Sarco SP7-20?
If you encounter ERROR 10 with your Spirax Sarco Valve Positioners, it indicates that the supply voltage was interrupted for at least 20 ms. To fix this, check both the power source and the wiring.
What to do if I get ALARM 2 on Spirax Sarco SP7-20 Valve Positioners?
If you receive ALARM 2 on your Spirax Sarco Valve Positioners, it means the setpoint current is outside the permissible range (less than 3.8 mA or greater than 20.5 mA). To solve this, check the power source.
How to troubleshoot ERROR 11 on Spirax Sarco SP7-20?
If you encounter ERROR 11 with your Spirax Sarco Valve Positioners, it means the supply voltage has fallen below the minimum voltage. To resolve this, check the power source and the wiring.
What causes TIMEOUT on Spirax Sarco Valve Positioners?
If your Spirax Sarco Valve Positioners display TIMEOUT, it means the automatic adjustment function is taking too long. You can increase the supply pressure or use boosters to resolve this.
What to do when ALARM 7 appears on Spirax Sarco SP7-20 Valve Positioners?
If your Spirax Sarco Valve Positioners display ALARM 7, it means the specified limit value for the travel counter has been exceeded. Reset the counter (only possible via a connected PC with suitable software).
What does it mean when Spirax Sarco Valve Positioners show ERROR 50 to 99?
If you are seeing errors in the range of ERROR 50 to 99 on your Spirax Sarco Valve Positioners, this indicates an internal error. If the error can be reproduced and occurs in the same position after resetting, the device must be returned for repair to the manufacturer.
What to do when ALARM 6 appears on Spirax Sarco Valve Positioners?
If your Spirax Sarco Valve Positioners display ALARM 6, it means the defined limit value for the stroke counter has been exceeded. Reset the counter (only possible via a connected PC with suitable software).
Why is ALARM 4 appearing on my Spirax Sarco SP7-20?
If you receive ALARM 4 on your Spirax Sarco Valve Positioners, it indicates that controlling is inactive because the device does not operate in control mode or the binary input is active. To solve this, switch to control mode or switch off the binary input.
What does ALARM 3 indicate on Spirax Sarco SP7-20?
If you receive ALARM 3 on your Spirax Sarco Valve Positioners, it indicates the zero position has shifted by more than 4%. Correct the mounting to resolve this.
