15.2.1.54 Binary output: CtrlHeartBeat
Related FW 3.0
Description The output provides alternating signal with rate 500ms active / 500ms
inactive while the controller is
operational , i.e. it has passed all checks after
startup and no failure was detected.
If the output does not provide the alternating signal it may indicate following:

controller is switched off or

controller is damaged or

incorrect/missing firmware and/or application or

corrupted setpoints
The output is intended for using in wired redundancy systems at the main
controller. Learn more about redundancy in separate chapter

controllers .
15.2.1.55 Binary output: BTB status
Related FW 3.0
Description This output indicates the BTB position, how it is internally considered in the
controller. The position is based on
BTB feedback input and optionally also
on the BTB fdb neg input.

If only the positive feedback input is used the output mirrors the
feedback.

If both feedbacks are used and they match each other the output
indicates the BTB position according to the feedbacks.

If both feedbacks are used, however they do not match each other,
the output remains in previous position when they matched.
The output can be used for indication of the BTB position.
