  • Page 4: A Model Cc-3 Interim Release Upgrade Information

    A Model CC-3 Interim Release Upgrade Information The Sigma Systems Model CC-3 Controller you have received was shipped with Interim Release, version 7.0.0, firmware. One of the features of the CC-3 is it’ s ability to receive firmware updates via the serial port. Please take the time now to complete the form at the end of this Interim Release Software section and mail to Sigma in the enclosed envelope.

    A.2 Final Release Additions The following features, not in the interim release, will be in the final firmware: Probe level temperature correction Remote control temperature correction Average probe temperature control Direct access to setup parameters Remote control command queue placement acknowledgment Remote control command start acknowledgment Remote control command completion acknowledgment Nested control loops...

  • Page 6: B Hardware & General Revisions

    B Hardware & General Revisions The new CC-3 introduces a number of new improvements to make the controller faster and more reliable than its predecessor. The CC-3 has a completely new digital processing board. The new board has a much faster processor, more memory, and a much faster IEEE-488 GPIB controller. Interrupts have been completely restructured to improve stability.

  • Page 7: Temp Range At Startup

    This setting can only be changed by Sigma Systems service personnel. We recommend that each controller be kept with the device for which it was originally configured.

  • Page 8: Probe Out Of Range Shutdown

    When in Fahrenheit mode, temperature displays have an “ F” following the probe identifier on the left side of the display. Example: p1 f 1 02. 4 Likewise, temperature inquires over the bus (PT command - see Section 5.1.15 in CC- 3 Manual) will return a string with an “...

  • Page 9: Internal Error Shutdown Conditions

    The minus sign in the display indicates that the reported temperature was below the operating range of the controller and the absence of the minus sign indicates that it was above the operating range. Note that because the CC-3 will report a HI or LO condition and stop controlling for an error of 20-50°C, the only events that will typically trigger an Err or -Err condition is a failure of the sensing circuit, most likely an open circuit (Err) or short (-Err).

  • Page 10: Memory Signature Checking

    B.6.2 Memory signature checking Each time the CC-3 is powered up, the system checks a series of memory signature bytes to test the integrity of system memory. If the signature bytes are not correct, the system assumes that memory has been compromised. If this should occur (a normal event any time a memory chip is replaced) all of system memory is reinitialized.
  • Page 11 points. C1 & C2 are the corrected, or actual, temperature at those same two points. Thus to make a correction using ice water (0°C) and boiling water (100°C) when the display shows 2.3°C for the ice water and 99°C for the boiling water, the user would enter the following: The CC-3 will then calculate a new slope and offset for the probe curve.

  • Page 12: C Program Mode Revisions

    C Program Mode Revisions C.1 Insert/Delete step Front panel programming of the CC-3 has been made easier by the addition of program step insert and delete capabilities. In the CC-3, unused program steps that were in the middle of an existing program could not be deleted. Instead, the next step pointer of the prior step was changed to point to the next valid step, bypassing the unused step.

  • Page 13: Any Step Can Point To Step 100

    C.2 Any step can point to step 100 The CC-3 restricted some steps in that they were not permitted to be the last executable step and in program and point to step 100 (program end). The CC-3 has no such restrictions. Any step can be the last step and point to step 100, even if doing so makes no sense.

    D Remote Mode Revisions D.1 RS232 baud rates 19,200 38,400 The CC-3 is capable of RS-232 communications at higher baud rates. Setup field #3 now accepts two additional values: 19,200 baud 38,400 baud D.2 RS232 bus initialized upon setting to remote The CC-3 required that to use the RS-232 port, the port had to be initialized by switching the mode switch to SETUP before switching to REMOTE mode.

  • Page 15: Qv Query Version Command

    D.5 QV Query Version Command This command returns the current internal firmware release number in the following format: QV nnn.nnn.nnn<CR><LF> Where nnn is the number of each part of the release number, padded on the left with leading zeros if necessary. D.6 QU Quit Command This command causes the CC-3 to stop controlling in the same manner as reaching step 100, program end, in Program mode.
