Switching on outputs All outputs are simultaneous-
ly switch on after the supply
voltage has ramped up,
delay time of 24 ms or
100 ms can be programmed
for outputs to be sequentially
switched on.
All outputs are simultaneously switched-on after the supply
voltage ramps up > 20 V, delay time of 25 ms, 100 ms – or
"load optimized" where the outputs are sequentially
switched-on, selected using the DIP switch.
Shutdown characteristics SITOP select:
Figure 6-1 Shutdown characteristic SITOP select
● An output current is continuously permissible up to the selected current response
threshold.
● In the range 101 - 129 % of the selected current response threshold, an overload current
is permissible for 5 seconds; after this time, the output is electronically shut down.
● In the range > 130 % of the selected current response threshold, the current is limited to
130 %; after approximately 50 - 100 ms, the output is electronically shut down.
● When the output current exceeds the selected current response threshold, and if the
supply voltage simultaneously dips below 20 V, then the output is electronically
shutdown.
