Description

• NCNA-01 Basic Calibration of RTD Input

   Enable ambient temperature sensing with the S2 SYSTEM SETUP 

  AMBIENT TEMP  AMBIENT TEMPERATURE SENSING setpoint.

   Connect a thermocouple to the NCNA-01 relay terminals B10, B11, and B12 and

  read through the A2 METERING  AMBIENT TEMP  AMBIENT

  TEMPERATURE actual value.

• 
•  

   Compare the displayed value of temperature against known temperature

  at the location of the sensor.

  Use a thermometer or other means of obtaining actual temperature.

  An alternative approach is to perform NCNA-01 a more detailed calibration per the procedure

  outlined below.

  7.4.5.2 Detailed Calibration of RTD Input

  1. Alter the following setpoints. Set S2 SYSTEM SETUP  AMBIENT TEMP  AMBIENT

  TEMPERATURE SENSING to Enabled and set S2 SYSTEM SETUP  AMBIENT TEMP 

  AMBIENT RTD TYPE to the desired type.

  The measured values should be ±2°C or ±4°F.

  2. Alter the resistance applied to the RTD NCNA-01 input (note the 3-input connection must be

  used for the measurements to be valid) as per the typical table below to simulate RTDs

  and verify accuracy of the measured values.

  3. View the measured values in A2 METERING  AMBIENT TEMP  AMBIENT

  TEMPERATURE.

  Refer to RTD tables included in this manual for calibration of resistance versus

  temperature.

• Ambient Temperature by Monthly Averages

   If the ambient temperature is entered as 12 monthly averages, program

  the value for the month during which the relay is being commissioned.

   Examine the A2 METERING  AMBIENT TEMP  AMBIENT

  TEMPERATURE actual value to verify the NCNA-01 programmed temperature.

   Verify that values entered for other months do not affect the value for

  the present month.

  7.4.6 Analog outputs

  The analog output settings are located in the S2 SYSTEM SETUP  ANALOG OUTPUTS

  setpoints section.

   Connect a milliammeter to the analog output contacts: COM on A5 and

  analog output 1 on A6, analog output 2 on A7, analog output 3 on A8,

  analog output 4 on A9, analog output 5 on A10, analog output 6 on A11,

  or analog output 7 on A12.

   From the settings used for the tested NCNA-01 analog output, determine the mA

  range for the output and the driving signal and its range for the full

  range of output current.

   Apply the input signal and vary its amplitude over the full range and

  ensure the analog output current is the correct amplitude.

   Record the results in the table below.

   Duplicate as required for each analog output.
