July 2012
Wireless Dual Analog Input Interface Transmitter
This section covers the various messages, displayed on the Transmitter
LCD, that occur during operation of the device.
Operations Sequence
•
RF Link Status

RF OK – Transmitter and Base Radio are communicating
properly

RF SYNC - Transmitter and Base Radio are attempting to
synchronize communications.

RF OFF - Transmitter's RF Channel is set to RF OFF

NO RF - Transmitter and Base Radio have no communica-
tions
•
Analog Input Level

–XX.XX – Currently measured Analog Input level
Error Messages
If an error is detected with the operation of the Transmitter a message will
be displayed on the Transmitter LCD (a corresponding message may also
appear on the Base Radio LCD).
There are few types of error messages, warning and fatal. Warning mes-
sages are displayed as part of the normal cycling message sequence. These
are:
•
LOW BAT - battery should be replaced as soon as possible
•
NO RF - can not detect Base Radio
•
S FAULT - there is an open sensor or excitation wire detected.
Also if a sensor value goes above/below logical limits. The unit will
display 9999.99 for measurement (sensor fault mode); but will con-
tinue sampling and recover if the problem desists.
•
OVERRNG - the device is measuring a value above/below sensor
dependent bound values. For example the Analog Input device will
report over-range if measurement is above 100% range of the Analog
Input sensor. If the measurement goes above 150% full range, the unit
will go into Sensor Fault mode. In over-range mode, the measurement
is continued to be displayed, with the "OVERRNG" message to re-
mind the user that the specified range of the sensor and the calibrated
range of the device is being exceeded.
Fatal error messages will replace the normal cycling message sequence
and will flash. A fatal message indicates the Transmitter is no longer oper-
ating normally and requires repair. These are:
•
RF ERR - fatal error within RF communications
•
SEN ERR - fatal error within the sensor electronics
•
SYS ERR - fatal error within the microprocessor system
•
RF CAL - fatal error within the RF calibration system
