Band (indicated as gain) 0.25-25% of span 4) Rate with tracking reset **4-255 seconds 5) Auto Tune (AT) Up/Down keys: increases/decreases values of above adjustments. Tune/Cancel: "cancel" puts output on stand-by to permit set-up "tune" triggers automatic tuning procedure E Enter: writes selected value to nonvolatile memory NOTES: *setting to zero initiates 60 millisecond timebase for ultra fast cycling. Use withexternal solid state relays or SCR Power Controllers. **Setting to zero disables reset and rate action for proportional only control. Reset is six times higher than rate FOR OPTIMUM RESULTS WITH THE AUTO-TUNE MODEL 6050 1. Set point must be a minimum of 100°F above ambient for proper start-up. 2. Multi-zone applications require auto-tune units on each zone and simultaneous warm-up. 4 3. Loss of power or turn-off during warm-up requires a re-start from ambient. 4. Change of state processes, i.e. solid to liquid or liquid to gas, may introduce erroneous tuning parameters during process warm-up. GENERAL 1. Accurately measures, linearizes and displays temperature in °F and °C. 2. Automatically calculates and displays parameters-heat gain, and rate/reset time. 3. Can be field converted from relay output "B", to solid state relay “T", to solid state driver "S" or to a 4-20 MA output SCR driver "F". 4. Will remember its "entered" settings after power failure or shut-off and not "Go To Sleep". CAUTION: HIGH VOLTAGE AN0 HIGH TEMPERATURES CAN CAUSE INJURY AN0 ARE A FIRE HAZARO. PLEASE REAO ALL INSTRUCTIONS, HAVE ONLY SKILLED PROFESSIONALS WIRE THE UNIT, AND USE APPROVED TEMPERATURE AND/OR PRESSURE SAFETY CONTROL. EVEN THE BEST COMPONENTS CAN BE DAMAGED OR MAY NOT FAIL SAFE. CONFIGURATION Depending on the model number of the unit you have ordered, vou will find one of four basic modules installed. The fifth digit of the code indicate the output module type. B -Relay 7A/5A @ 120/240 Vac F -4-20 mA (Proportional) T -Triac 1 Amp @ 240 Vac S -20 VDC Pulsed for driving solid state relays Example: 6050-F has proportional 4 to 20 mA heat output. Note: If you have not received your controller from the factory direct, check to confirm that the correct module for your application is installed. Since the modules plug-in, and since controller plug into cases as well, previous users may have changed modules, which can result in severe controller damage. 5 Output Modules The Athena 6050 offers users 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 resistive heaters. NOTE: Do not use this output module with mechanical contactors because they generate an excessive EM1 field which can interfere the 6050's microprocessor. Instead we recommend "T" output modules for this application. Module Type F: This 4-20mA output module can deliver full output to loads having an input impedance of 500 Ohms or less. The cycle time setting must be ZERO for smooth current output. A push-on terminal is utilized as a return for ground currents of the milliamp source. It is connected internally to the mating lug on the heat sink. To avoid ground loops, drive floating (ungrounded) loads or use isolated thermocouples. Module Type T: This solid state relay is capable of 1 AM? at 120/240 Vac. It is zero voltage switched and optically isolated from the drive signal. With it, resistive loads up to 120 watts at at 120 Vac and 240 watts at 240 Vac may be controlled directly. Using direct control there is no lower ...
