8.2.2 RTD for Sensor 1 is Open or Shorted.
There is an open or short in the sensor RTD or wiring.
A. If sensor is being installed for the first time, check the wiring connections. See Section 3.2.
B. Disconnect the sensor from the analyzer and measure the resistance between the RTD lead wires. See the
sensor manual to identify the RTD leads. If there is an open or short circuit, replace the sensor.
C. If there is no open or short, check the analyzer. See Section 8.5.

8.1 OVERVIEW
The Solu Comp II continuously monitors itself and the sensor for faults. When the analyzer detects a fault, the
word fault appears in the display alternately with the measurement. If alarm 3 was configured as a fault alarm,
the alarm relay will energize. The outputs do not change during a fault condition. They continue to reflect the
measured ozone or temperature. Press
"
to display the fault codes.
NOTE
A large number of information screens are available to aid troubleshooting. The most useful of these are
raw sensor current and sensitivity and zero current at last calibration. To view the information screens,
go to the main display and press the

key.

8.2.1 Sensor Current Exceeds 210
µµ
A
Excessive sensor current implies that the sensor is miswired or the sensor has failed.
