➀ total smoothing time ≤2 ms
➁ -20...0...+20 mA by setting S1
➂ 4...20 mA by ➁ + Software function
➃ -1...0...-1 V by setting S2/S3 (CMR ±10 V)
-2...0...-2 mA by setting S2/S3 + S1 (CMR ±10 V)
➄ designated for PT100 evaluation per firmware and
hardware
➅ If the input is used for tacho feedback and the tacho
voltage needs to be scaled, the board PS5311 must be
ordered separate. If this input is used for feedback
signals, there is a need for additional margin for
overshoot measurement. This margin is set by software
and results e.g. in the 8 to 33 volts at PS5311.

➆Residual current detection is selected as default. The jumpers S1:11-12 and S1:13-14 are set, inputs X3:9 and X3:10
and jumper S1:9-10 must not be used and inputs X3:11 and X3:12 serve as input for the current signal taken from a
current transformer. This detection is based on a sum current transformer where the secondary is connected through a
diode bridge to 100 W resistor . Voltage will appear across the resistor, if the sum of the 3-phase current is not zero. In
case AI4 should be used for a different purpose, use the inputs/jumpers accordingly and take the block diagram as a
help.
Restrictions using jumper S1, S2 or S3:
The selection for the burden resistor across the input terminals can be done independent from S2 or S3 settings for inputs
AITAC, AI1, AI2, AI3 and AI4.
If the gain is set to 10 by using S2 or S3 and the 500 W burden resistor is activated, the input signal level is changed to -2
mA...0...+2 mA.
For input AI4 there are the following configurations available:
- input range "20mA" , or
- input range "10V", or
- earth fault monitoring by Isum not equal to zero via X3:11 and X3:12

Note:
When the SDCS-CON-4 control board with the SDCS-IOB-3 I/O
board is installed, analogue tacho input at SDCS-CON-4 should
be used:
Terminals X3:, X4: and X5: on the SDCS-CON-4 must not be used
