Parameters
A005 AT Terminal selection VIC 00 or 01 01
Setting Function
00 Switching between 0...10V and 4...20mA (O / OI)
01 Switching between 0...10V and -10...+10V (O / O2)
A006 O2 Control selection VIC 00 to 02 00
Setting Function
00 Single reference value (without f-correction)
01 Addition of f-correction without changing direction
02 Addition of f-correction with change of direction

1.) Set digital input to function “16 AT switch-over to automatic reference value”
(0...open, 1...closed)
2.) Change of direction allowed (if sum of reference values < 0)
If no digital input is set to “16 AT Switch-over to automatic reference value”, A006 has following
function:
Setting Function
00 Single reference value -10...+10V
01 Addition of 0...10V and 4...20mA without changing direction
02 Addition of 0...10V and 4...20mA with change of direction
A016 Time constant for analog signals VIC 1...30 30
In order to realize shoerter reaction times to changes of the reference values, the set value for this
function can be reduced. However, the smaller this value, the smaller the filter effect for interfering
residual frequency on the reference signal is.
Setting 1 ............................ 30
Filter effect for interfering frequency low ................ high
Reaction time to changes in reference fast .......... slow
