3.2.3 Running CirrusPro Software
Having checked that all the connections are correct, both pipe work and wiring, the system can now
be commissioned:
1. Apply power to the detector unit. The PC can be powered when this occurs but it is usually better
that the CirrusPro Software is not running.
2. The unit will commence a power up sequence:
Tunes the pump to find most efficient frequency.
Checks that the pump can produce the required vacuum.
Puts the chamber under pressure and checks vacuum retention.
Starts the blower.
Checks for water, to determine if a water fill is needed.
Checks that the stored settings match the actual settings
Sets the LED current.
3. Double click the CirrusPro Icon to start the program. This will display the screen as shown below:
Set the com port.
Every unit leaves the factory set to Network Number 255. This means that on a network all the
units will try to communicate at the same time. This is why the RS485 connections need to be
disconnected at this time.
When programmed, the connected units are found and listed as below, showing all the connected
CirrusPro Units and their Network Number:
By default, the identifier is Network Number followed by the unit Serial Number (found on the
PCB). For example ‘224 Unit 000000B3’. The serial number can be replaced under program
control to location text as required.
The PC searches back from unit 255 and waits for a reply. This timeout can vary on different PCs
so it could take some time to get to the lower numbers if used in isolation. Using the higher
numbers will speed up the logging of connected units.
