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

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

S1 Sense Line Open

EEPROM Failure

8.2.1 Sensor Current Exceeds 210 µ µ A

Excessive sensor current implies that the sensor is miswired or the sensor has failed.

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.
