DDC mode or BL has priority over manual mode (S29 = 0)
*) yE is either yN or yES (S42). In DDC mode the manipulated variable current of the K controller
can be switched off with S36 = 1 (operation with two output stages). The external y source
must be made to track the effective variable y, if DDC mode is not present.
**) When using the digital input BE, only one of the control variables CB, BL or Si is possible as
defined by S15.
***) The data on "Signals front LED" (e.g. 0.5) refer to the flashing frequency (see 3.2.6).
(n) The variable is made to track the last value effective before switchover, thus ensuring hitchless
switchover.
NOT(RC) = NOT{NOT(INT) AND CB)} NOT(RB) = INT OR H / = adjustable
