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 outp

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 thi

INTERNAL SWITCHES Damping Control -To allow the controller to provide automatic tuning for processes with varying heating characteristics and with varying heating capabilities, the 6050 offers three damping choices: High damping: for over-powered heating systems, systems with multiple heat lags, and/or poor coupling between the heater and the temperature sensor. Normal: for most standard processes where the heater is properly sized for the system and there is good coupling between the heater and

THERMOCOUPLE PLACEMENT Proper thermocouple placement can eliminate many problems in the system. The probe should be placed so that it can detect any temperature change with minimal thermal lag. In a process that requires fairly constant heat output, the probe should be placed close to the heater. In processes where the heat demand is variable, the probe should be close to the work area. Some experimenting with probe location is often needed to find its optimum position. In a bath process, additi

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. A) Hold "Index" button until STEP 3: To enter a set point: 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

How to override automatic tuning parameters It is possible to set or fine tune three mode parameters manually on the 6050. To manually enter parameters: 1) Press "Index" button until the LED for the desired parameter lights. 2) Enter the new parameter using the up or down key. 3) Press the "enter" button. The new parameters will now take control of the process. To calculate the PID parameters without using the automatic tuning mode, consult the Athena 6000/6200 instruction manual. Reading autom

TROUBLE SHOOTING no instrument power. Front dark - Process display shows CCCC - Open thermcouple. Short terminals 1 and 2. Process display should indicate temperature at back of case. Repair or replace thermocouple. About Half or Twice Expected Reading - Check position of °C/°F switch. Short 1 and 2 to read room temperature. 22-30 is °C, 70-85 is °F. About 30% Error - Wrong thermocouple type. Disconnect couple. "J" units over range above 14OO°F, "K" above 2500°F. No Heat - No heater power, heate
