  • Page 4: Installation

    INSTALLATION Mount the instrument in a location that will not be subject to excessive temperature, shock, or vibration. All models are designed for mounting in an enclosed panel. Select the position desired for the instrument on the panel. If more than one instru- ment is required, maintain the minimum of spacing requirements as shown on the drawing below.

  • Page 5: Wiring

    WIRING Do not run RTD, thermocouple, or other class 2 wiring in the same conduit as power leads. Use only the type of thermocouple or RTD probe for which the control has been programmed. Maintain separation between wiring of sensor, optional inputs and outputs and other wiring.

    THE HOME DISPLAY The home display is the normal display while the control is operating. If no errors or functions are active, the HOME display will indicate the Process Variable (the tem- perature, pressure, flow, RH, etc., that is being measured) on the top display and the Set Variable (Set Point 1) on the bottom.

    to the target value desired for the first ramp. This value is in actual units just like . If the control is programmed for temperature, then the SP displays are in temperature. If the control is programmed for some other engineering unit, the SP is set in that unit.
  • Page 14 Pressing the AUTO / MANUAL key will also suspend the program operation. The difference is that AUTO / MANUAL also puts the control into manual mode. See Auto / Manual operation on page 14. StAt The function of the Primary Menu will change depending on the setting of the menu StAt item in the Secondary Menu.

  • Page 15: Auto / Manual Operation (16A3 Only)

    AUTO / MANUAL OPERATION (16A3 ONLY) The AUTO / MANUAL function allows you to manually adjust the output of the con- trol. This is normally used during process setup or start up. It can also be used for troubleshooting. To switch from AUTO to MANUAL press the AUTO / MANU- AL key and hold for three seconds.

  • Page 16: Operation Self Tune Function

    Operating of Self Tune Function Self Tune allows automatic selection of the necessary parameters to achieve best control operation from your 16A2 & 16A3 Series control. If you are using the con- 0n0F trol output as a simple on-off function ( set for ), none of the following will apply.

    OPERATION AND PROGRAMMING OF OPTIONS Option 992, 993, 995, 996 Serial Communication The serial communications options allow the control to be written to and read from a remote computer or other similar digital device. Communication is allowed either through a RS-485 (Option 992, 996) port, or a RS-232 (Option 993, 995) port. Wire the communication lines as shown on Page 7.
  • Page 18 This is the type of memory that all Love Controls uses to save the settings your program in your con- trol. The reliability and longevity of the data retention is what allows us to guarantee a 10 year data retention without power.
