Option Code Requirements/Specification
C1:
Factory Data
(1)
Date: day/month/year
Descriptor: 16 alphanumeric character
Message: 32 alphanumeric character
Custom Alarm Levels can be specified for configuration at the factory.
C2:
Transmitter Sensor Matching
The transmitters are designed to accept Callendar-van Dusen constants from a calibrated RTD
schedule and generate a custom curve to match any specific sensor curve. Specify a Series 68, 65, or
78 RTD sensor on the order with a special characterization curve (V or X8Q4 option). These constants
will be programmed into the transmitter with this option.
C4:
Five Point Calibration
Will include five-point calibration at 0, 25, 50, 75, and 100% analog and digital output points.
Use with option code Q4 to obtain a Calibration Certificate.
C7:
Special Sensor
Used for non-standard sensor, adding a special sensor or expanding input.
Customer must supply the non-standard sensor information.Additional special curve will be added to
sensor curve input choices.
A1: NAMUR-
Compliant, high alarm
Analog output levels compliant with NAMUR. Alarm is set to fail high.
CN: NAMUR-
Compliant, low alarm
Analog output levels compliant with NAMUR. Alarm is set to fail low.
C8: Low Alarm Analog output levels compliant with Rosemount standard. Alarm is set to fail low
F5: 50 Hz Line Filter Calibrated to 50 Hz line voltage filter.
