c) Reading actual values
The AI provides the DC terminal values as current and voltage monitor. These can be
read using a standard multimeter or similar.
d) Switching between source and sink mode
You can also switch between both modes when remotely controlling the device with the AI. This is done using the
voltagesetvalue(VSEL),whichthenmustnotbetiedtoaxedpotential,likeshowninexampleb).Rules:
• if the voltage set value on VSEL (in %, not the level) becomes higher than the actual voltage on the DC terminal,
the device will switch to sink mode, no matter if the voltage on the DC terminal is generated by the device or
from external
• if if the voltage set value becomes lower than the actual voltage, the device will switch to source mode
