Sigma C4 manual Custom Features / Interchangeability Warning, Release 7.5.2 Firmware

1.3 Custom Features / Interchangeability WARNING

Each Sigma Systems C4 Controller has been custom configured for the chamber or platform with which it was supplied or for which it was specified. Many units include special wiring for custom control applications, precision fail-safe additions, non-standard voltages, external unit power control, etc. Units that may appear to be identical may be internally quite different. Do not interchange controllers between controlled devices (chambers and/or platforms) unless you are certain that the controllers have been identically constructed.

Failure to heed this warning voids your warranty, may cause unpredictable controlled device behavior that could cause damage to persons or property, pose a risk of fire, or cause other problems. If you must move controllers between controlled devices, please contact the Sigma technical support department for assistance and advice.

1.4 Release 7.5.2 Firmware

This manual is specifically written to cover the features of Release 7.5.2 firmware for the Sigma Systems Model C4 controller. The features of this release firmware are largely backward compatible with all CC-3 and earlier CC-3.5& C4 firmware.

This release fixes a number of bugs found in the CC-3.5interim release versions 6.8.6, 6.9.0, and 7.0.0. It also adds a number of new features. See Section 1.5.

Note: This release implements probe temperature correction on a per probe basis. Interim CC-3.5releases implemented this feature on a global basis.

Sigma highly recommends that all users update to the latest firmware release. Contact Sigma Technical Support. See Section 9.10.

Note: This release is not available as an upload file for serial port firmware updating of your controller. Due to non-backward compatible change in the way some data is stored internally, this version must be installed using a PROM obtained from Sigma Systems.
