This document includes a list of enhancements available beginning with PAX2C firmware version 1.5 and describes the conversion process for converting version 1.0x PAX2C file to a version 1.5+ file.
PAX2C
In order to utilize the new features, the previous firmware version database files must be converted in order to use those files in a PAX2C with version 1.5 firmware. Instructions for converting a version 1.0x program file to be used in a version 1.5 PAX2C are included in this document.
Crimson 2.0 Build 572 or later
PAX2C Ver 1.51 or later
Added in Version 1.50 Firmware
NOTE: Programming modules affected by the enhancements include: process input scaling, display locks, and PID settings.
If you have an existing application and associated database file, you may continue to use the database on the new PAX2C using your current build of Crimson 2.0 or the latest Crimson 2.0 build contained on the USB flash drive. Simply download (Link, Send) the database file to the new PAX2C. In the download process, the new PAX2C will be “down-graded” to version 1.0x and configured for your application. If you use the build of Crimson 2.0 contained on the included USB flash drive, review the following change to the Band and Deviation Alarm Modes for version 1.06 PAX2C firmware, as it may affect your application.
The PAX2C Band/Deviation alarm modes have been changed to provide setpoint tracking. As the setpoint is changed, the alarm trigger points will shift to provide alarming around the new setpoint. If you’ve previously set the alarm value to accomplish this, it is no longer necessary. The alarm value, however, will need to be set to zero; otherwise an alarm offset will occur. Refer to the Alarm Figures in the PAX2C manual contained on the USB flash drive.
The easiest method to convert a 1.0x database file is to use the latest build of Crimson 2.0 to extract the database file from a version 1.0x PAX2C. The extracted database is then sent to the new PAX2C. To do this, follow the procedure below.
If a version 1.0x PAX2C is not available, another conversion method is to send the existing 1.0x database file to the new PAX2C, as is. Then extract into a new version 1.5 database file, and resend to the PAX2C.
Beginning with version 1.5, the Proportional Band units have been changed from % input range to display units. If keying in the Proportional Band value from a version 1.0x unit, the Proportional Band value must
be converted from % input range to display units. Note: The latest build of Crimson 2.0 will convert the values automatically when extracting the database from a version 1.0x PAX2C into a version 1.5 database.
Version 1.0x Settings:
Proportional Band = 21.4
Input Type = T
Display Scale = °C
Display Decimal = 0.0
Conversion of the version 1.0x Proportional Band value from % input range to display units, can be accomplished using the following formula:
Ver 1.5 Proportional Band = Input Range * (Ver 1.0x Proportional Band /100)
Using the Input Range Tables below, select the input type range for the applicable input type. In this example, we are using a Type T thermocouple, so the input range value would be 600 °C.
By substituting known values into the equation above, the version 1.5 proportional band can be calculated:
Ver 1.5 Proportional Band = Input Range * (Ver 1.0x Proportional Band /100)
Ver 1.5 Proportional Band = 600 * (21.4/100)
Ver 1.5 Proportional Band = 128.4 (For Display Scale = °F, multiply result by 1.8: For Display
Decimal point = 0, round result to nearest whole unit)
