Controller / Communications
All analyzer functions are controlled by microprocessors housed within
the analyzer. These include:
One fully configurable analog output (4 to 20 mA) that can be self-
powered or externally powered.
Three alarm contacts (data valid, concentration alarm, and system
alarm).
One RS-232 or one RS-485 serial interface provides communication be-
tween the analyzer and your recording or data acquisition equipment.
The Model 3050-AMS analyzer is configured, and analyzer parameters are
set, by using either the analyzer display, keypad and function keys, or us-
ing an external PC.
4-line x 20-character LCD display that provides moisture data, system
operating parameters, system messages, and alarm conditions.
An 18-button keypad on the front of the unit that is used to set or
change operating parameters and system values.
Serial interface to an external PC.

System Alarm
Activates (contact opens) when a condition exists that makes analyzer
output questionable. Such conditions include:
- cell temperature alarm
- zero error
- battery alarm
Moisture Concentration Alarm
Activates (contact opens) when a moisture concentration exceeds the
programmed alarm levels.
