KASSIE2 - NORMAL OPERATION
When setup properly, the device will run repeatedly through the following sequence:
1. Take sensor readings and upload data to webserver
2. Take sensor readings and save data internally
3. While waiting for the next scheduled upload, the device will :
(a) measure and display temperature one sensor after the other.
(b) For each of the 8 probes, switches a relay ON or OFF between the user defined temperature limits. Normally switch off when the LOW limit is reached, and ON again when the HIGH limit is reached.
(c) provide an option to enter the device's MENU
(d) repeat (a) and (c) continually - wait stage
4. Operation return back to step1.
All readings are taken and saved with datetime stamp.

KASSIE ALARM CONDITIONS
In the case of a sensor reporting a temperature outside the set limits, KASSIE2 will close the relay contacts which can in turn activate a siren or warning light (see electrical circuit). Warning Emails will also be sent to all interested parties. GMail on mobile phones make it convenient to get email notifications immediately. The email will contain the name of the alarming station, the temperature and date & time.
Relevant email addresses are required by PEETLAB to built it into the UPLOAD Command. In the MENU OPTIONS below, it will be explained how to reset a temperature alarm.

ALARM ACKNOWLEDGEMENTS
When an alarm email is received, the receiver may respond to acknowledge the notification whereby further alarm emails will not be send out on that day for that station.
Acknowledgements is done per probe station valid only for the day it is sent. The Acknowledgements is done via the Mobile Application only.

Connecting probes for normal operation
Before connecting/adding/replacing any sensors/probes to the DATA LINE, the device must be switched off.
The device can then only be switched on with all the sensors wires properly connected in parallel to Vcc (5V), GND and Data.

SENSOR SETUP - Kassie2Mobile App
The temperature sensors (18B20) must be set up one by one. Each probe must be connected to the SETUP PORT (right side of the unit) through the included SETUP CABLE.
Warning : Do not use the PROGRAMMING PORT on top of the device for this purpose.
Then label the probe with any tag to identify it from other probes on the system. Giving it a name which identify a location is a good idea. The reports will refer to this name/label.
Example : Coldroom Front, Coldroom Door, Outside, Precooler..

Warning: See recommended procedure for connecting the probes.

(a). Select a Probe number ( Probe1 to Probe 8)
(b). Click GO
(c) Assign a name to the probe (label)
(d) Enter the LOW level value, and mark the checkbox with a tick if the value is negative. A temperature below this value will trigger an alarm.
(e).Enter the HIGH level value, and mark the checkbox with a tick if the value is negative. A temperature beyond this value will trigger an alarm.
(f). Check MAKE PROBE ACTIVE for the system to know which of the possible 8 temperature stations are used.
(g). Click SAVE. then.
(h). Click UPLOAD.
On UPLOAD, KASSIE2 will respond immediately. It will display the label of the probe on the first LCD line, and on the second LCD line it will display the probe station number, the low value, the high value and another 3 digits. The first two digits represent the sign of the values. "1" = negative, "0" = positive. The last digit : "1" = probe is marked active, "0" = probe is not marked active and system will ignore it on reports. The LCD display will last 3 seconds and it will read and show the serial number of the probe.
(i). Repeat steps (a) to (h) above for setting up the next probe or click CLOSE to exit the SENSOR SETUP page.
