Page 11: Section 3 Output Modules
SECTION 3 OUTPUT MODULES Module Description The Athena 6075 offers field interchangeable output modules. This unique feature makes it possible to fill output requirements for a variety of applications with a single controller model. Module Type B: This 7A/5A relay (at 120/240 Vac) is used for driving resis- tive heaters. - Page 14 Standard Thermocouples Materials I.SA.

- Page 15 watchdog circuits and filtering built into the unit Contacts and coils must be suppressed! One very effective filter is a .1 ufd/600V capacitor in series with a 100 Ohm, 1/2 watt (min.) resistor. This network must be put on all contacts, especially across hard contacts that are switching coils and across the coils themselves.

Page 18: Setup
Basic Series 6075 Setup 1. The 6075 has dual-input ranges which allow selection of one of two ranges and T/C types, by simply moving the position of the internal jumper. To set unit to proper range, remove unit from case and position jumper on top board. - Page 19 . R ange of Adjustments (Parameters) All parameters are accessed by pressing the INDEX key. They listed in the order they are displayed when the lNDEX key is pressed. The front panel of the Model 6075 contains a lower display of 5 digits which displays the set point temperature, the other parameter values and degrees F or C.

- Page 23 SPECIAL NOTE: For Units utilizing only heating output, the cooling gain should be set by the user to the equivalent heat gain. The inverse is also true. Setting CG to 0 initiates an on-off (narrow deadband) output for cooling, which is recommended for cooling-only applications. Setting HG to 0 disables the Heat output.

PlD settings or manually setting the unit as desired. Tuning a 3-Mode controller involves three (3) major adjustments; propor- tional Band (Gain), Rate (Derivative) and Reset (lntegral) action. Athena has simplified the adjustment procedure with the incorporation of the Rate and Reset settings into one adjustment "RT"... -

Normal Damping - For processes that: (any combination of the following) have heaters that are properly sized. have good coupling between heater and probe. are considered standard with moderate lags and response time. High Damping - For processes that (any combination of the fol- lowing) - are overpowered - have multiple lags... -
Page 26: Manual Tuning Procedure
STEP 6: When ready to start Auto-Tuning calculation of PlD settings press the “Enter/Tune” button. The displays will return to process and set point displayed. The F/C digit will blink while tuning is in pro- cess. Upon completion of tuning, the digit will stop blinking. T stop the Auto-Tuning press standby/cancel. - Page 28 4. Press STAND-BY again and temperature will begin to rise. When the pro- cess rises to the desired set point it will probably oscillate. Periodically decrease the Gain (lower the HG number) until a small constant oscilla- tion is obtained. Reducing the Gain by steps of one half (1/2) the previous -HG- setting is an acceptable method to obtain the desired small oscilla- tion.
