All electrical installation and maintenance work described in this chapter
should only be undertaken by qualified service personnel. The Safety instructions on
the first pages of this manual must be followed.
Diagnostic displays
The bypass detects error situations and reports them using:
• The green and red status LEDs on the bypass control panel
• The bypass control panel display
The form of the display depends on the severity of the error. You can specify the
severity for many errors by directing the bypass to:
• Ignore the error situation.
• Report the situation as a warning.
• Report the situation as a fault.
Red – faults
The bypass signals that it has detected a severe error, or fault, by:
• Enabling the red Faulted LED on the bypass (LED is either steady on or blinking).
• Overriding the control panel display with the display of a fault code.
• Stopping the motor (if it was on).
The message reappears after 30 seconds if the control panel is not touched and the
fault is still active. The Faulted LED remains active (either steady on or blinking)
even when the fault display is silenced.
Flashing display – warnings
For less severe errors, called warnings, the diagnostic display is advisory. For these
situations, the bypass is simply reporting that it had detected something “unusual.” In
these situations, the bypass overrides the control panel display with the display of a
warning code and/or name.
The warning code on the display flashes over the current display. Pressing any key
silences the warning message. The message reappears after 30 seconds if the
control panel is not touched and the warning is still active.
