Table 5: Channel-Wise Interlock Connector Pin Assignment
Each interlock input is galvanically isolated (optocouplers). If a channel is interlocked, it is
not possible to switch it on.
Signal level:
interlocked:
-10 V ... +0.8 V
not interlocked: +2.2 V ... +10 V (input impedance 1 kΩ + LED, so higher input
voltages can be used if an external resistor is implemented.)
