  • Page 4: Installation

    Installation Measurements between centerlines of panel cutouts are the minimum recommended. Unpacking and Inspection 1. Inspect shipping carton for obvious signs of mishandling. 2. After removing the controller from the shipping carton, inspect it carefully for damage. Never attempt to install and use a damaged unit.
  • Page 5 Sensor Input Make sure that you are using the appropriate thermocouple and extension wire. Connect the negative lead Connections (generally colored red in ISA-type thermocouples) to contact #9; connect the positive lead to contact #10. Extension wires must be the same polarity as the thermocouple. Figure 4.

  • Page 6: Wiring

    Voltage Inputs: Connect the positive voltage input to contact #10; the negative input to contact #8. mV/ Current Inputs: Connect the positive current input to contact #10; the negative input to #9. Power Wiring The Series 16 power supply accepts 100 to 250 Vac and 100 to 330 Vdc line power without any switch settings or polarity considerations.

  • Page 7: Operation

    Athena Series 16 Universal Controller The Series 16 is a full-function, autotuning PID controller, calibrated and pre-configured for your application Operation requirements, according to the ordering code specified, either as a temperature or linear process controller. (See page 39 for specifications and ordering code).
  • Page 8 Power On Operation When power is first applied to the Series 16, both displays and all LED indicators are momentarily illuminated. The Process Value (PV) window then displays [ -At- ] or [ -Ap- ] and the Setpoint Value (SV) window displays an initialization code, e.g., [ tf06 ].

  • Page 9: Parameter Menu Organization

    Menu Level Descriptions Menu “05” (Configuration Setup) This is the menu level used for specifying initial configuration parameters before the controller is placed in Operation Run mode. Because the Series 16’s initial configuration affects other menu levels, it is important to set all required parameters in this menu first before accessing other menu levels.

(With “Y” modules, an alarm may be configured only on [ ]) When one of the two available Outputs is configured as an alarm, the other Output may be used for control .

  • Page 16: Tuning

    Introduction The Series 16 is an “on demand” autotuning controller that automatically sets PID parameter values Tuning (Proportional Band, Reset and Rate) before the process reaches setpoint. A damping setting (menu level Procedures “02”) MUST be selected for autotuning to take place. The controller may also be tuned manually. Autotuning the Series 16 Temperature Controller For best results in 1) With the power off and the process at ambient, apply power and immediately put the controller in...
  • Page 17 Manual Tuning Procedure - Temperature Controller (Zeigler-Nichols PID Method) Tuning This tuning method may be used if the spread between ambient temperature and process operating Procedures temperature is small. For best results, the use of a recording device is suggested when tuning with this method.

  • Page 18: Auto/Manual

    Tuning Manual Tuning Procedure - Process Controller (Zeigler-Nichols PID Method) A chart recorder to monitor the process variable is required. The controller must be properly scaled and Procedures filtering set as instructed previously. 1) Apply power and place the controller in Standby by holding the Mode key for four seconds.

  • Page 19: Remote Setpoint Select

    Special Remote Setpoint Select Functions If your Series 16 controller was ordered with this option, you may select either of two setpoints for your process. The second setpoint can be enabled only by an external switch or signal, according to your ordering specifications.

  • Page 20: Process Variable Retransmission

    Special Functions Process Variable Retransmission If your Series 16 controller was ordered with this option, you may retransmit the signal representing the process variable for analysis or storage to an external device that accepts analog input, such as a chart recorder, datalogger, or process control computer.

  • Page 21: Heater Break Alarm

    Special Functions Heater Break Alarm (Series 16 Temperature Controller) The heater break alarm option detects failures in the load or power handler and provides an alarm output. It uses an external current transformer to monitor the load current. If the load current falls below a set current value, the alarm output is activated.

    Transducer Excitation Special The transducer excitation voltage option is used to produce a constant dc voltage of 10, 12 or 15 Vdc out to Functions an external device, eliminating the need for an additional external power supply. Refer to the ordering code if you do not know which voltage output was specified.

  • Page 32: Glossary

    Alarm Delay - the time delay between the detection of the alarm condition and the initiation and indication of the output action. Glossary Alarm Inhibit - prevents low setpoint alarm activation during cold startup applications. Autotuning - “Autotuning” or “self-tuning” simplifies process control by determining the tuning parameters based on an automated analysis of the controlled process’s behavior.
  • Page 33 Lowest Reading - records the lowest process value read by the controller. May be reset to zero by using the Raise or Lower arrow keys. Lower Setpoint Limit - prohibits users from adjusting the setpoint lower than the selected value. Manual Reset - an adjustment that moves the Proportional Band up or down by a fixed percentage so that more or less power is applied at setpoint.
