If the Signet Transmitter displays the message “Pulse Overrun Output1”, it means that the open collector pulse rate exceeds the maximum of 300 pulses per minute, or the pulse width is set too wide. To resolve this, try increasing the Pulse volume setting, decreasing the pulse width setting, or reducing the system flow rate.
Why is the Open Collector of my Signet Transmitter always activated?
If the Open Collector of your Signet Transmitter is always activated, it could be due to a hysteresis value that is too large or a defective transmitter. Try changing the hysteresis value. If the issue persists, consider replacing the transmitter.
What to do if Signet 8550-1 says “Value must be more than 0”?
If the Signet Transmitter shows “Value must be more than 0”, it means that you are trying to set the K-factor to 0, which is not allowed. Enter a K-factor between 0.0001 and 99999.
What to do if my Signet 8550-1 displays 'Pulse Overrun'?
If your Signet Transmitter displays 'Pulse Overrun', it indicates that the open collector pulse rate exceeds the maximum of 300 pulses per minute or the pulse width is set too wide. To resolve this, try the following: * Increase the Pulse volume setting. * Decrease the pulse width setting. * Reduce system flow rate.
What to do if my Signet 8550-1 Transmitter shows '– – – – –'?
If your Signet Transmitter displays '– – – – –', it means the flow rate exceeds its display capability. You can resolve this by increasing the flow units time base or moving the flow decimal one place to the right.
Why is the Open Collector always activated on my Signet 8550-1?
The Open Collector might be always activated on your Signet Transmitter because the hysteresis value is too large or the transmitter is defective. Try changing the hysteresis value. If the issue persists, consider replacing the transmitter.
What to do if Signet 8550-1 Transmitter displays 'Value must be more than 0|'?
If your Signet Transmitter displays 'Value must be more than 0|', it means the K-factors cannot be set to 0. Enter a K-factor from 0.0001 to 99999.
How to fix Signet Transmitter displaying “- - - - -”?
If your Signet Transmitter displays “- - - - -”, it indicates that the flow rate exceeds the display capability. To fix this, increase the Flow units time base or move the flow decimal one place to the right.
