Example of Change Configuration, Parameter Verify

Note: When the installer proceeds with the safety parameter configuration, the control unlocks the safety parameters in this group and marks them unusable. Failure to complete the entire safety configuration procedure leaves the control in an un- runnable state (lockout 2).

All safety configuration parameters in the group should have the same access level. If this condition isn’t so, the user is asked to enter another password when a higher access level is needed.

Successful login is noted by the lock icon, which changes to “unlocked” on the page. The installer may begin to change safety parameters (or any other parameters) at that time (see Figure 61). If the Burner Control is in an unconfigured (or new) state, then this warning doesn’t appear. All parameters that need changes should be changed during the login.

VERIFY

Pressing the Verify button displays safety configuration parameters for an additional verification step to commit the changes.

Safety parameters are grouped into blocks that include only safety parameters, not a mixture of safety data and non-safety data. All parameters within the safety group undergo a verification process. A safety parameter group is identified on the display to indicate when the configuration parameters are safety-related. Each safety parameter group is verified one at a time until all have been verified. See Figure 60.

Figure 60. SAFETY VERIFICATION

Like operating parameters, safety parameters can be viewed without the need to enter a password.

Safety parameter blocks that have been changed require verification. The verification steps do not have to be completed immediately; the installer can move between and change parameter groups before the verification is done. A Verify button is enabled that allows the installer to conduct verification sessions (the example of the Verify button in Figure 55 is not yet enabled because the installer hasn’t logged in).

Figure 61. EDIT SAFETY DATA

If the safety configuration session is terminated after it has started (in the Edit or Verify stages), the Burner Control is left in an unconfigured (unrunnable) state.

The installer can terminate the session by pressing the Menu button or by attempting to leave the Verification page with the Home or Back buttons (top-left and -right screen corners, respectively). However, leaving the session at this point leaves the control in an unrunnable state and confirms whether the installer still wants to do so.

The settings of all parameters in each safety block must be verified to save them in the control.

When the installer is done changing safety parameters, pressing the Verify button on the configuration screen begins the Verification process. The settings for all safety parameters in each changed block are presented and Verified by the installer (see Figure 62 on Page 56).
