CLASSIC 800 Product Manual
I. THE KAYDEN CLASSIC 800 - DIGITAL ELECTRONICS FEATURES
The CLASSIC 800 is v ersatile, rugged, cost effectiv e and easy to use. All setup and adjustments may be
performed using the Display Panel buttons. The CLASSIC 800’s Display Panel displays process condition
(flow, lev
el & interface) v ia the Thermal Signal Bar Graph as well as Relay state, Timer functions and
operating conditions v ia indiv idual LEDs. The CLASSIC 800 may also be remotely controlled and/or
monitored v ia RS-485 using the Kayden RCM (Remote Control & Monitoring) Software and the Serial
Communication Adapter (SCA) and communication cable.
Kayden’s CLASSIC 800 series uses an adv anced microprocessor to perform continuous self-test
diagnostics on the Electronics Module and the sensor elements.
• Any open or shorted connection will result in an error indication that also opens all output contacts
and disables the heater circuitry.
•
An internal watchdog circuit ensures that the microprocessor code is performing as expected and a
secondary external watchdog circuit ensures that the microprocessor itself is functioning. Both
circuits force the contacts open, illuminate the Fault LED and turn the heater off and de-energize
the relays in the ev
ent of a malfunction. This prev ents the heater running out-of-control that would
result in excessiv e temperatures on the probe or a burnt-out heater.
• The microprocessor also monitors the heater for out-of-range conditions. For example in a lev el
application when the sensor is “dry” for an extended period of time, the heater will cycle between
its current setting and a lower power rating until such time as the sensor is again submerged.
