Device specific Failure Error message Error correction
Transmitter F Sensor break channel 1 Sensor wire broken. Check the sensor and sensor
connection on the channel 1. If error remains replace the
sensor connected to channel 1.
Transmitter F Sensor break channel 2 Sensor wire broken. Check the sensor and sensor
connection on the channel 2. If error remains replace the
sensor connected to channel 2.
Transmitter F Sensor short circuit
channel 1
Sensor wire shorted. Check the sensor and sensor
connection on the channel 1. If error remains replace the
sensor connected to channel 1.
Transmitter F Sensor short circuit
channel 2
Sensor wire shorted. Check the sensor and sensor
connection on the channel 2. If error remains replace the
sensor connected to channel 2.
Transmitter F Sensor low isolation
channel 1
To low isolation in the sensor. Check the sensor by
measuring resistance between the wires. If error remains
replace the sensor connected to channel 1.
Transmitter F Sensor low isolation
channel 2
To low isolation in the sensor. Check the sensor by
measuring resistance between the wires. If error remains
replace the sensor connected to channel 2.
Transmitter F Sensor drift Check the sensors and limits for sensor drift. If error
remains replace the faulty sensor.
Transmitter F System error Make a self test to find out more. If the error remains
replace the device.
