Section 7 – Input Calibration
This section describes the field calibration procedures for Input 1 and
Input 2. Every UDC 3300 controller contains all input actuation ranges
fully factory calibrated and ready for configuration to range by the user.
However, these procedures can be implemented if the factory calibration
of the desired range is not within specifications.
Note that the field calibration will be lost if a change in input type
configuration is implemented at a later time. The original factory
calibration data remains available for later use after a field calibration is
done.
This section contains the following topics:
7.1 Overview
7.2 Minimum and maximum range values
7.3 Preliminary Information
• Disconnect the field wiring
• Equipment needed
7.4 Input 1, 2, or 3 Set Up Wiring
• Thermocouple inputs using an ice bath
• Thermocouple inputs using a precision resistor
• RTD (Resistance Thermometer Device) inputs
• Radiamatic, Millivolts, or Volts except 0-10 Volts
• 0 to 10 Volts input
• 4-20 Milliamps input
7.5 Input 1, 2, or 3 Calibration Procedure
7.6 Restoring Factory Calibration
WARNING—SHOCK HAZARD
INPUT CALIBRATION MAY REQUIRE ACCESS TO
HAZARDOUS LIVE CIRCUITS, AND SHOULD ONLY BE
PERFORMED BY QUALIFIED SERVICE PERSONNEL.
MORE THAN ONE SWITCH MAY BE REQUIRED TO DE-
ENERGIZE UNIT BEFORE CALIBRATION.
