ERR.ACT Relay sensor error action (for REL.FUN = SETP, WIND or ERR):
Only relevant if IN.TYPE = TEMP, CURR and I.RANGE = 4-20,
POTM or LIN.R and R 0% is ≥ 18.
NONE (Note
3
) = Sensor error detection NOT enabled (Note
4
),
relay state at sensor error is undefined. (NOT for REL.FUN =
ERR)
OPEN = Relay contact is open at sensor error
CLOS = Relay contact is closed at sensor error
HOLD (Note
3
) = Relay contact holds the state as before sensor
error occurred. (NOT for REL.FUN = ERR)
ON.DEL Relay ON delay from SETP or SETP.LO/HI is crossed in units of
seconds (for REL.FUN = SETP or WIND)
OFF.DEL Relay OFF delay from SETP +/- HYST or SETP.LO/HI +/- HYST
is crossed in units of seconds (for REL.FUN = SETP or WIND)
Note
3
:
Value not allowed if the relay is used in a safety application (EN.SIL =
YES) and IN.TYPE = CUR and loop supply is used to supply a current input signal.
Note
4
: Error detection is enabled if OUT.ERR ≠ none, but relay state at sensor
erroris undefined.
14.1.3. Parameters related to analouge output
Name Function
O.RANGE Fixed output range for current output:
0-20 = 0...20 mA
Value not allowed when EN.SIL = YES (Safety applications)
4-20 = 4...20 mA
20-0 = 20...0 mA
Value not allowed when EN.SIL = YES (Safety applications)
20-4 = 20...4 mA
OUT.ERR Fixed output value on detected sensor error:
NONE (Note
5
) = Sensor error detection NOT enabled (Note
6
),
output at sensor error is undefined.
The end user must ensure that the applied sensor including
wiring has a failure rate qualifying it for the safety application
without the detection enabled.
0 mA = Output is 0 mA at sensor error
3.5 mA = Output is 3.5 mA at sensor error (NE43 downscale)
23 mA = Output is 23 mA at sensor error (NE4 upscale)
