6-52 Terminal 42 Output Max Scale
Value:
000 – 200%
Function:
Scale the maximum output of the selected analog
signal at terminal 42. Set the value to the maxi-
mum value of the current signal output. Scale the
output to give a current lower than 20 mA at full
scale; or 20 mA at an output below 100% of the
maximum signal value. If 20 mA is the desired
output current at a value between 0 - 100% of the
full-scale output, programme the percentage val-
ue in the parameter, i.e. 50% = 20 mA. If a cur-
rent between 4 and 20 mA is desired at maximum
output (100%), calculate the percentage value as
follows:
m A desired maximum current x
20 /

6-53 Terminal 42 Output Bus Control
Value:
0.00 – 100.00 %
Function:
Holds the level of Output 42 if controlled by bus.

6-54 Terminal 42 Output Timeout Preset
Value:
0.00 – 100.00 %
Function:
Holds the preset level of Output 42.
In case of a bus timeout and a timeout function is
selected in par. 6-50 the output will preset to this
level.
6-6* Analog Output 2 (MCB 101)
Analog outputs are current outputs: 0/4 - 20 mA.
Common terminal (terminal X30/7) is the same
terminal and electrical potential for analog com-
mon connection. Resolution on analog output is
12 bit.
