Register Description
KL3311, KL3312, KL3314 and KL3302 13
User parameters
R32: Feature register
[0x1006]
The feature register specifies the terminal's operating mode.
Feature bit
no.
Description of the operating mode
Bit 0 1 User scaling (R33, R44) active [0]
Bit 1 1 Manufacturer scaling (R19, R20)
active [1]
Bit 2 1 Watchdog timer active [1]
In the delivery state, the watchdog
timer is switched on.
Bit 3 1 Sign / amount representation [0]
Sign / amount representation is active
instead of two's-complement
representation. (-1 = 0x8001)
Bit 4 1 Siemens output format [0]
This bit is used for inserting status
information on the lowest 3 bits (see
below).
Bit 5 1 Activates filter constant in R37 [0]
Bit 6 1 Deactivates the measuring current for
broken wire detection
Bit 7 - reserved, do not change!
Bit 8 1 Reference temperature off [0]
Bit 9 - reserved, do not change!
Bit 10 1 Checking of the lower measuring range
limit not applicable. [0]
