Configuration
The 8 curve settings for the configurable VDO inputs cannot be changed in the display, but only in
the TPS 300 software.
The binary inputs are based on the VDO inputs, i.e. if a VDO input is selected, the binary input
cannot be chosen, and vice versa. When selected as multi-functional inputs, the 3 VDO inputs can
be changed to binary inputs with cable supervision. The cable supervision is selectable (ON/OFF)
and based on the VDO inputs using a 100 Ohm resistor across the monitored switch. The resulting
function is:
R < 20 Ohm =
30 < R < 140 Ohm =
150 Ohm < R =
The setting of the alarm input is carried out in the same way as the setting of the standard binary
input. The texts can be changed in translation.
