Why Honeywell STT25H gives incorrect output signal with simulating device?
To resolve an incorrect output signal with a simulating device, verify the sensor wiring is correct and then power cycle the device. When changing the configuration, ensure the sensor wiring is correctly connected before making any configuration changes. The most common error is changing the sensor wiring after probe type selection or after power-up.
What to do if Honeywell STT25H shows "INVALID REQUEST" when changing LRV or URV?
If the LRV is changed, the URV tries to change by the same amount to maintain the same SPAN. If this new URV exceeds the URL then this message appears. To fix this, reduce the URV or SPAN before changing the LRV.
What to do when changing LRV or URV on Honeywell STT25H Transmitter?
If the LRV is changed, the URV tries to change by the same amount to maintain the same SPAN. If this new URV exceeds the URL then this message appears. Make sure that: LRV >= LRL and that URV
How to fix high input on Honeywell Transmitter?
To address a high input issue, inspect the field wiring and connections for any partial short circuits. Also, ensure the STT250 connections have the correct polarity. Verify that the transmitter is operating within its specified voltage range and that the line resistance is not excessively high. High input can be caused by a bad sensor wire connection or incorrect operating voltage.
Why Honeywell Transmitter has unstable onscale input?
To resolve unstable onscale input, check the connection and wiring for intermittent connections. Ensure that sensor fault detection is set to "ON" to detect a faulty sensor. Protect the wiring by implementing proper grounding and shielding. This can be caused by a bad sensor wire connection, an intermittent open circuit of the sensor, or wiring disturbed by strong electromagnetic interference.
How to troubleshoot no input or low input on Honeywell STT25H Transmitter?
To address the issue of no input or low input, you should inspect the field wiring and connections. Ensure that the transmitter is operating within its specified voltage range. Also, verify that the 250 ohms resistor is present in the loop. This issue can be caused by a bad sensor wire connection or an incorrect operating voltage.
