Troubleshooting
No signal
• Check that Vdc power is connected to the signal loop
circuit (V+ at trans signal terminal).
• Polarity reversed- check by reversing the + and - leads
at the input terminals.
Output greater than 20.0 mA
• Check zero output of transmitter—adjust zero to 4.00
mA if necessary.
• Check span setting—adjust to 20.00 mA at nominal
range or calculated full pressure.
Maximum output less than 20.00 mA
• Check that applied pressure is within span limits
for transmitter range. (Transmitter has ± 40% span
adjustment.)
• Check span setting—adjust to 20.00 mA at nominal
range or calculated full pressure.
• Higher resistive load on signal loop may exceed voltage/
load capacity (see page 5).
