Cycle power.
Er06 - Zone 1 A/D under flow error
•
Incorrect sensor type
•

the sensor range
•
Check the InP1 setup
parameter. Verify that it matches
the sensor.
•

for a reversed or open sensor. If
the condition causing the error is
resolved, the error will clear.
Er07 - Zone 1 A/D overflow error
Open sensor
•
Check the InP1 setup
parameter. Verify that it matches
the sensor.
•
Check sensor and connections
for a reversed or open sensor. If
the condition causing the error is
resolved, the error will clear.
Er10 - Stack overflow error
Microprocessor malfunction
•
Cycle Power.
•
Check sensor and connections
for a reversed or open sensor.
Er11 - Open sensor error
Open sensor
•
Check the InP1 setup
parameter. Verify that it matches
the sensor.
•
Check sensor and connections
for a reversed or open sensor.
Er12 - Shorted sensor
•
Incorrect sensor type
•
Measuring temperature outside
the sensor range
•
Check the InP1 setup
parameter. Verify that it matches
the sensor.
•
Check sensor and connections
for a reversed or open sensor.
