Chapter 1 Overview
1-1 General
The LCR20 is a microprocessor based 10 inch circular chart recorder.
Programmable alarm options combined with “ease of setup” provide the
fl exibility required for a multitude of recording applications.
The Ink style LCR20 is the fi rst recorder with “self documenting”
confi guration during initial setup. It can operate using standard or
competitive charts. The battery backup feature provides up to 48 hours of
recording in the event of a power loss, providing an additional degree of
protection for customer processes.
A unique setup template provides the user with an “on the spot” manual.
This setup template will also self document the current setup for quick
review by an operator.
These units are powered by a fi eld selectable 110/220VAC 50/60Hz.
supply. A 9 Volt battery allows for operation for up to 48 hours if the main
power supply fails. Standard inputs are programmable for thermocouple
types J, K, T, R, B and S as well as 4-20mA or 0-5 VDC.
Optional alarm relay is available and programmable for low, hi, or band in
latching or non-latching operation.
High accuracy, maximum fl exibility, fast response and a simple interface
are the main benefi ts of the LCR20 recorder.
