UPT-6011
Version 5
The limits of the tolerance band are adjustable up to a maximum of
±
99 K.
8.6.7
Control active (RA)
The UPT-6011 has successfully accepted the "START" request and entered control mode if the RA bit = 1.
8.6.8
Info active (IA)
This bit is reserved for future use and is not currently supported (it is always set to 0).
8.6.9
Standby active (SA)
The SA bit has the following functions:
The so-called "handshake" procedure for the RS bit (reset).
The following prerequisite must be fulfilled for the "handshake" procedure:
• The 24 V supply of the controller and the line voltage are switched on.
The SA bit becomes active when the RS bit (reset)
or
the MP bit (measurement pause) are set to "1" ("handshake"
procedure). In this way, the control detects when the controller has accepted the RS bit or the MP bit. The tem-
perature controller can then delete the RS bit or the MP bit again.
The controller waits for line voltage.
The following prerequisite must be fulfilled for this function:
• The 24 V supply of the controller is switched on.
The SA bit becomes active when the temperature controller is waiting for the line voltage to be switched on for the
first time.
