ISSUE:
Constant High Output
CHECK FOR:
Open on sensor side.
• Confirm wiring
• Confirm connection to sensor
• Measure sensor bridge resistance for any internal opens.
High output from sensor.
• Measure ± Signal input from sensor to amplifier to see if
sensor has a high output.
• Excitation must be provided to sensor when measuring
± Signal input.
Ensure sensor is not under load or stress.
• Remove sensor from application and fixtures to test for
installation stress.
ISSUE:
Damaged Amplifier
Given the cost of a new amplifier we recommend a new
purchase over a possible repair which can include evaluation
cost, repair cost, calibration cost, shipping, and time loss.
For system calibration a RMA would be recommended with
the intent that a new amplifier would be recommended but
sensor will be present for calibration to new amplifier.
Some items that can damage amplifier:
• Connection to power with power already on.
• Connection of power to incorrect pins.
• Shorts or incorrect wir-ing on output connec-tions or
excitation pins.
ISSUE:
Constant Low Output
CHECK FOR:
Power to amplifier.
• Confirm supply of 12.5VDC to 26VDC.
• Confirm power connection wiring. Positive on Pin 1 +Vin
and ground on Pin 2 Gnd.
• Power LED on amplifier should be on.
Short on sensor side.
• Confirm wiring
• Confirm connection to sensor
• Measure sensor bridge re-sistance for any internal
shorts.
Ensure load is applied properly to sensor.
• Ensure load is not being supported by items other than
sensor.
• Take sensor out of application and apply a known load.
Check shunt.
• Shunt function should simulate an output on the sensor.
