[edit] System Reset

Resets the controller. All active processes will be disabled, and any unsaved changes lost.

[edit] Reset to Defaults

Resets the controller to factory defaults. All saved settings will be removed, and the controller reset. A dialog box will ask for confirmation of reset to defaults.

[edit] System Inputs and Outputs

Note: All settings on this page require the user to press the "Apply" button to be saved in the controllers non-volatile memory. When settings are applied, the page automatically refreshes. Under certain rare network conditions, the refresh will occur before the apply is complete, resulting in previous data being read, even though the controller has been updated properly. It is good practice to manually press the "Refresh" button every time after the "Apply" button to ensure correct data is being displayed.

[edit] Temperature Probe Inputs

Update the names of the temperature probes. Temp inputs must be enabled to cause exit conditions.

[edit] Thermistor Steinhart-Hart Coefficients

See Calibrate Temperature Probes.

[edit] Discrete Inputs

Discrete Inputs is a fancy way of saying normal switch. DINs can be used for any purpose you can think of, for example use with a float switch while fly sparging or wiring up to a traditional switch for the old fashioned big read panic button. Dins must be enabled to cause exit conditions.

[edit] Discrete Outputs

Update the names of the outputs. Enable outputs here in order to allow them to be asserted.

[edit] Heat/Cool

If using the output in either Differential Control or PID Control, which are controls associated with temperature inputs, the Heat/Cool setting tells the controller whether to assert the output if the temperature is below the setpoint (heat to temp), or if it is above the setpoint (cool to temp).

[edit] PID Sample Rate

See PID Implementation

[edit] Output Period

See Output PWM Control

[edit] PID and Differential Output Control Settings

• Associate with Temp Input - If outputs are to be programmed with either Differential or PID control, they must be associated with a temperature input.
• Differential Swing - The range parameter of Differential control. If an output is programmed as Heat with a swing of 4deg, it will be asserted ON if the associated temperature is less than (setpoint - swing/2), and asserted OFF if the temperature is greater than (setpoint + swing/2). Output assertions are reversed in Cool mode.
• PID Controller Gains - Program the PID parameters. See PID Implementation.

[edit] Miscellaneous System Settings

• Enable Authentication - If set provides basic password protection. Password can be updated below. Default password is "control".

• Run at Powerup - Each process and Manual Mode can be set to run at powerup. This is useful if processes are designed to recover from a power failure.
• Celsius Mode - Temperatures are displayed in Celsius (vs. the default Fahrenheit).
• 50% PID Mode (Backward Compatibility) - See PID Implementation
• Active Outputs in Main Control Red/Green - Sets the color of the active outputs in the Output Display Bar. This setting is a browser cookie, not saved in the controller itself.
• Path to Alarm Sound - This is the sound that is played in the Main Control page during an alarm. "./alarm_clock.mp3" is the default, which resides local on the controller. Users can change the alarm sound path here to add custom sounds by entering the URL of an mp3 file. This setting is a browser cookie, not saved in the controller itself.

[edit] System Save

Saves a configuration file. The file name will default to bcs_config.cfg, and can be downloaded from the controller. All settings are saved, excluding network settings and cookie based parameters. For the structure of the file, see Open Interface.

[edit] System Restore

Loads and Restores a configuration file. Loading a configuration file will take a few seconds, and upon successful load, the user will be directed to a blank white screen. The BCS unit will only restore configuration files of the same firmware version. If presented a config of a different firmware version, the controller will reset itself.

[edit] Firmware Update

See Updating Firmware.

[edit] User Password Change

The default password is "control". This is the password used when Authentication is enabled. The 'User' password grants the user all privileges to update the system. Passwords can be a maximum of 8 characters. During a "Reset to Defaults", the password will also be reset.

[edit] Observer Password Change

The default password is also "control". Change this password to be different than the 'User' password above to grant users 'Observer' privileges. When logged in with the Observer password, users are able to monitor the BCS-460, but not update settings.
