OPERATING INSTRUCTIONS
How to Start the automatic tuning procedure
STEP 1: Energize the unit and proceed immediately to step 2.
STEP 2: Place the unit on standby by holding the "Index"
button until the "Autotune" LED lights then press
the Cancel button.
The unit is now ready for set point and cycle time entry.
STEP 3: To enter a set point: A) Hold "Index" button until
the SP LED lights and B) Use the appropriate touch
key, either up or down to enter set point.
When you've entered the desired set point, simply
press the enter key. NOTE: Set point must be at
least 100°F above ambient.
STEP 4: Set cycle time by advancing "Index" to "HC" and
select desired value using up or down keys. Cycle
time is shown in seconds, from 1-120. Setting zero
initiates a 60 millisecond cycle time for ultra fast
cycling for use with "F" or "S" output modules. For
mechanical relays or contactors use l0-120 seconds.
When you've found the desired cycle time press the
enter key.
STEP 5: To start warm up and calculate all PID parameters
advance Index to auto tune again and press the
"tune" button.
The "AT" L.E.D. will light and "HT" L.E.D. will
light. You may now index to any parameter for
viewing as process heats. Upon completion of
tuning, the "AT" L.E.D. will be off.
NOTE: The parameters that the 6050 calculates automatically
can be entered on the Athena 6000/6200 to achieve the
same smooth and precise temperature control on your
process.
