Summary of Contents for Athena 2000 Series

  • Page 1 2000 Series Temperature/Process Controller Operation Manual...
  • Page 2 Introduction Congratulations on your purchase of an Athena® Series 2000 analog temperature controller. It is a U.L. listed, 1/4-DIN controller for use in a variety of applications. Standard features include time proportioning with auto-adjusting cycle time, adjustable bandwidth (for on-off to wide band proportioning), and offset (manual reset).

    Shielded sensor cables should always be terminated at one end only. If additional RFI attenuation is required, noise suppression devices such as an R.C. snubber at the external noise source may be used. If you wish, you may order this suppressor directly from Athena, part number 235Z005U01.

(Non-inductive loads only) For larger loads, replace heater connections with contactor, as required. Maximum inductive load rating is 3 A at 120 V and 1.5 A at 240 V. The N.C. con- tacts can be used for cooling.

  • Page 6: Thermocouple Wiring Circuits

    Wiring -F, -S Output - 120/240 Vac The -F output is 20 mA at the low temperature end of the proportional band and 4 mA at the upper end of the proportional band. Maximum load resistance is 1000 ohms. The -S output is a time-proportioned 20 Vdc signal. These controllers cannot be used with a device that does not have an isolated input.

  • Page 7: Thermocouple Placement

    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 little 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.

  • Page 8: Front Panel Layout

    Layout of the front panel is shown below. To reach the adjustments, swing the top of the door forward and down. The proportional band adjustment is on the right side and sets the gain of the controller. The offset Front Panel (manual reset) adjustment is on the left and corrects for offsets from the setpoint temperature.

    Configuring Output Function There is a switch assembly on the bottom board (see bottom board illustration). This four-position switch regulates cycle time and output selection. It is factory-configured for the plug- in output ordered. Check the Switches output function chart to make sure the configuration is correct for your application. Switches 1&2: These switches act together to select either proportional current output or one of the time proportioning cycle times.

    How to Set Reset, Proportional Band, and Rate Optional 3 Mode Auto reset action automatically, but slowly, corrects droop error in proportionally controlled processes. Ideal (PID) reset time is one half the period of oscillation of the process. Slower settings are safe, but sluggish. Faster settings will cause continuous oscillation.
