I) Overview
General
The CR500 is a microprocessor based circle chart recorder. Programmable alarm options
combined with “ease of setup” provide the flexibility required for multiple recording
applications. This manual will cover both ink type and thermal print versions.
The CR500 is the first recorder to “self document” setup configuration during initial
setup and can operate using standard or competitive charts. The battery backup option (on
ink type units) provides up to 48 hours of recording in the event of power loss, thereby
providing an additional degree of protection for customer processes.
A green status LED
indicates battery condition; see Battery Backup (Page 17).
The Thermal print version offers a single chart inventory for all recording needs. “Print
your own” chart technology includes real time trend and printed time and date directly on
the chart. The Thermal Recorder provides dual channel recording as standard. Each
channel is configurable for universal inputs. The unit can easily be configured, in field, to
single channel via keypad.
The unit is powered by 110/220VAC, 50/60Hz. Programmable inputs for thermocouple
types J, K, T, R, B and S as well as 4-20mA are standard. Optional alarm relays are
available and are programmable for low, high or band operation. The green LED
indicates unit is powered.
A unique setup chart provides the user with an “on the spot” manual. This setup chart
will also self-document the current setup for quick review by an operator.
High accuracy, maximum flexibility, fast response, and a simple user interface are the
main benefits of the CR500 recorder.
