7300w² Monitor Instruction Manual
10 Faults
The majority of error messages are related to the performance of the sensors and/or measurements.
These messages are generated by and stored in the sensor. Please refer to the sensor manual for full
description of these messages.
Error messages are displayed in a number of locations: under the displayed value (usually in
conjunction with a flashing display), in the bottom information line and in the Info and Diagnostic
sections.
Whenever a 'Status' is reported as OK(0) the monitor is reporting a healthy system performance and
set up. The (0) relates to the no fault state of the monitor's operating system.
10.1 Monitor Error Messages
The only error message generated by the monitor is:
COMM FAULT
This indicates a fault with the communication between the monitor and one or more sensors. This is
sometimes reported with a (1) on the end of the message. The (1) refers the to the fault state of the
monitor's operating system and is not an indication of the number of the measurement at fault, nor the
number of sensors which are not communicating properly.
Before reacting to this message, please observe the monitor for a few minutes. The nature of the
ModTechw² protocol being used for communication between the monitor and sensors will occasionally
report transient errors which will clear themselves.
Communication errors can be caused by faulty or poorly installed cable, please check the connections
before taking any further action.
If the problem persists, contact Partech or your local Partech representative.
10.2 Sensor Error Messages
The majority of error messages displayed on the monitor will be reported by the sensor, these
messages will vary between sensor type. Sensors are self diagnostic and are able to detect out of
range, clean fault and other general error conditions.
Please refer to the sensor manual for specific sensor faults.
