Athena Technologies 6050 instruction manual Internal Switches, CELSIUS/FAHRENHEIT Display Section

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 the temperature sensor.

Low damping: for adequately powered systems with excellent coupling between the heater and the temperature sensor where quick response and the tightest possible temperature control are desired.

Keypad Security -Switch 2 in the open position locks the operator out of access to all parameters except set point.

CELSIUS/FAHRENHEIT DISPLAY SECTION

Switch 1 allows both displays to read in degrees Celsius or Fahrenheit, and is indicated on front panel LED's.

WIRING THERMOCOUPLE CIRCUITS

Before wiring, check thermocouple and extension wire to make sure that they conform to the appropriate thermocouple type specified on the serial number tag. In thermocouple circuits, the negative lead is colored red. Extension wires must be the same alloy and polarity as the couple. The thermocouple circuit resistance should not exceed 100 OHMS. Do not run thermocouple leads in the same conduit as the power lines. If shielded thermocouple is used, terminate the shield only at the controller end using the corner screw provided for that purpose.
