CB FALCON
750-265 18
STARTUP
The Falcon is shipped in the unconfigured condition, so when
power is applied, all safety loads are off and the burner status
when viewed from the display is shown as “Safety data setup
needed.”
Once the Safety Data is configured, the Falcon is ready to
operate a boiler.
Commissioning
Passwords
A password level of protection may be assigned to any
parameter. Three levels are shown in decreasing order of
privilege:
1. OEM password required —allows access to all parame-
ters
2. Installer password required —allows access to some
parameters
3. End User (no password) —allows access to non-pass-
word parameters
Whenever a valid password has been provided, the Falcon
remains in the access level of that password until either 10
minutes of inactivity (no more edits) has occurred or the
command is received to exit to the normal no-password state.
The OEM and Installer passwords are given a default value
when the Falcon is shipped, but may be changed later using
the Configuration program, the system display, or the
electronic configuration tool.
Parameter Control Blocks (PCB)
The Falcon Parameters are managed using control blocks.
There are three parameter control blocks (PCB) that may be
installed into the memory of the Falcon:
1. OEM Parameter PCB —makes any parameter hidden
and/or unalterable and assigns the password level
2. OEM Alert PCB —determines which alerts are enabled
and, for those that are enabled, if the alert causes the
alarm contacts to close.
3. OEM Range PCB —limits the range of any parameter.
A parameter control block can be downloaded using a file-
transfer method that operates within the Modbus protocol. The
Falcon Modbus defines the format of parameter control block
data and the download procedure. All of the OEM PCBs
require the OEM password before they can be downloaded.
The Software Configuration Tool allows all available
parameters to be viewed, modified, and downloaded. This tool
allows for building a device working from a spreadsheet.
Customizing can be done on this, along with choosing to have
the parameter Hidden, Read Only, or Level of Password
protection. When complete this sheet can be saved and/or
directly downloaded into the Falcon through the Modbus port.
An example is shown in Table 49, beginning on page 100.
OEM PARAMETER PCB:
Providing the OEM password allows downloading of a
parameter control block for OEM protected data. This block
assigns the value of these attributes for each parameter:
• Range Limit —If provided the parameter's value will be
limited.
• Hidden —This attribute prevents the parameter from
showing in the display - it is hidden.
• Read-only —This attribute prevents the parameter from
being changed.
• Password —The password attribute defines the level of
password needed to alter the item: OEM, Installer, or none.
The interaction and behavior of these settings is shown in
Table 6. (All parameters are readable via Modbus, however a
Modbus error response message is sent if an attempt is made
to write one that is marked read-only, or that requires a
password and the appropriate password level is not in-effect.)
OEM ALERT PCB
Providing the OEM password allows downloading of a
parameter control block for alerts.
• Each item in this block enables/disables the alert - a
disabled alert is never shown.
• An enabled alert has the option of closing the alarm
contacts, whenever this alert occurs.
OEM RANGE PCB
Providing the OEM password allows downloading of a
parameter control block for range limits.
• This block specifies the minimum and maximum values for
any writable parameter that accepts a numeric range, and
for parameters that are enumerated lists, it can suppress
