12 Calisto Manager

13 Installing Calisto Manager 1. Insert the CD or download the software from our website 2. Follow the on-screen instructions 3. At the Choosing Components step, make sure to check the USB Drivers box Notes: A notification window may appear, choose the Continue Anyway option Prior to starting Calisto Manager, your computer should be properly connected to the monitor using the supplied USB cable and proper drivers should be installed when asked by the operating system.

14 Connecting to a new Calisto 9 1. Launch Calisto Manager 2. Under Tracking, click on Add Monitor to List 3. At the Choosing Components step, check the USB Drivers box

15 Connecting to a new Calisto 9 4. Select Serial under Connection Type for local USB 5. Select the virtual COM create under Port 6. Click on Find (The monitor will appear in the Found Monitor window) 7. Click the Checkbox next to the monitor and click Add 8. The connected monitor will now appear in the list of monitors displayed in the main window

17 Settings Identification Adjust the date and time Enter the unit information

18 Settings Communication The RS485 ID is used as the monitor ID for all protocols.

19 Settings Oil Type Mineral Oil (ASTM3612) Voltesso 35 Technol US4000 Nytro Midel 7131 Silicone Envirotemp FR3 Luminol TRI Luminol TR Luminol BI Custom

20 Settings I/Os Dedicated 4-20 ma input for the Carrier Gas pressure

21 Settings Alarm Limits

22 Settings Relays

23 Settings - Relays Two different Fail-safe relay configurations: energized-when-always energized-when not-condition Morgan Schaffer recommends the following to establish the best levels of alarm limits and trend values: Work with the transformer manufacturer; Consult an industry expert; Carry out a statistical analysis of gas levels on a population of similar transformers being used in similar loading, environment, etc. Alarm level and relay logic should always be set with great care to maximize protection.

24 4. Maintenance

25 Maintenance The Calisto monitor is virtually maintenance free. To maximize product reliability, the following points should be verified every 6 to 12 months: 1. Install the latest firmware (if available) 2. Inspect the mounting 3. Inspect wiring, no unplugged entry holes 4. External fan is ON (for ambient > 15degC) 5. Internal fan is ON (always) 6. Verify the relay logic using Calisto Access 7. Ensure alarm limits are configured properly 8. Verify that the date and time are set properly 9. Verify that all valves are fully open 10. No material, cable, manual, etc. inside Calisto 11. Enclosure latches are tightened down 12. Inspect the oil line connections for possible leaks 13. Inspect underneath Calisto for possible leaks 14. Verify the response of the display

26 Maintenance Calisto 5 / Calisto 9 consumables to be replaced every 2 years: 1. Calibration gas cylinder 2. Carrier gas cylinder (helium) For more details, refer to the Calisto5/Calisto 9 Installation Manual and to the Calisto Manager User Guide.

27 Gas cylinder replacement Calisto 5 / Calisto 9

28 Starting the gas flow 1. Turn ON the monitor 2. Follow instructions on the Display (30 min.) 3. Go to Maintenance, then Combined bottle change Only open the gas cylinder shut-off valves as directed by the bottle change procedure to avoid contamination.

29 Installing the carrier gas cylinder Install the carrier gas adaptor onto the helium cylinder Note: You will require a large capacity 1 ½ adjustable wrench.

30 Installing the carrier gas cylinder Installing the high pressure carrier gas line 1. Connect the preswaged 1/8 tubing to the cylinder, tighten ¼ turn

31 Installing the calibration gas cylinder 1. Install the calibration gas cylinder inside the door 2. Insert one end of the cylinder in the bracket hole until captive screws become aligned with their respective nuts 3. Insert the preswaged 1/16 tubing and tighten 1/8 turn

32 Maintenance Most common error codes and respective solution: 1 External fan replace fan 2 Internal fan replace fan 2000 External analog input Wiring or Calisto Access 8000 No/low oil flow Verify all valves For more details, refer to the Calisto/Calisto 2 Installation and Operation Manual.
