Corrects a problem with interlocking a pulse proportional control output where the interlock is not lifted correct when the relay or digital input leaves the interlock state. Conductivity sensor alarm deadband will be calculated correctly. Hand Mode for pulse proportional outputs will now operate the pump at the maximum strokes per minute for the programmed Hand time.
The ranges for graphs of all disinfection sensor types will now be correct. The ranges for graphs of 2,4,8 and 12 hour durations will now be correct. Multiple alarm relays may be set up in any configuration without causing any problems.
In PID control, the Calculated Integral will not accumulate if the output is saturated. Analog output data may now be sent to VTouch. Deleting the Manual Datalog on download is now optional. Added the ability to superimpose an adjustable duty cycle on on/off set point control. All set points related to an input or analog output are displayed on the System Summary page. More time frame options are available for the graphs. Exported graphs now include the controller name and location in the image. Support for the latest 2G and 3G modems has been added. The following bugs have been fixed: Analog Outputs in the datalog when not available to select; Redundant Mode for Analog Flowmeters did not stop control or alarm; Changing set points in Flow Based Feed can activate the relay; Default manual temperature compensation is 77C not 25C; Parameters selected to show on LCD disappear after power cycle; Graphs show the wrong temperature input in the name; Averages not graphing; Graphs incorrect for analog inputs if scaled inversely; Graph data deleted if the Analog Input is rescaled; Custom Country Code field corruption; GPRS modem initialized incorrectly; Min, Max, Ave, Logging and Alarming still active during sensor calibration; Missing Manual Datalog download links; Log file changes date/time format; Log files drop parameters; Bleed Vol on Makeup Vol control mode calculation errors; Feed on % Time control mode calculation problems if less than 1% of time; On/Off Set Point control mode using analog input only allows settings in integers. PID calculations continue running when output is interlocked. Relay to relay interlocks occurring when relay is off; Pulse Proportional control mode set point units incorrect if flowmeter input used.
Prevents a 32-day online graph from stopping at 21 days. Prevents an empty online graph. Prevents flowmeter type analog input average being reported as the same as the current reading on the System Summary page. Prevents the auto-reporting logging frequency from being set to 0 min:sec. Prevents the controller from trying to re-synchronize the real time clock based on a bad reading, if the battery has failed.
Improves speed of relay pages loading after making changes and allows DI_4, 5 and 6 to be used in Counter Based Control mode.
Repairs bugs where a pH sensor in the Sensor 2 position could not be calibrated via the keypad, and temperature sensor alarm ranges being incorrect.
Now available for the new core. Version 7 upgrade is a very important upgrade to perform! This provides much more reliable USB connections and increases the robustness of the operating system. This upgrade must be performed from version 6, so if you are at a version below 6, do the upgrade to 6 first and then upgrade to version 7.
Fixes a problem with the keypad freezing for a few minutes at a time. Increases the range of temperatures for high temperature conductivity sensors before they go into a Temp Error alarm. Adds more country codes to the phone number pulldown lists, and allows for manual entry of a country code. Paddlewheel type water meters may now be used as an input for a Proportional Control type analog output. Added the ability to use a non-standard SMTP port to send emails.
