7.1.5 Operation with two variable output voltages (2 steps)
Switchover between two variable output voltages for the operational mode
of external control (Dipswitch S1-3 OFF position) is possible by means of
external potential-free contact-making.
Step 1 (low speed)
When there is no input signal connected to the input terminal “E“ or “E1”,
then the unit supplies the output voltage set by “n-min”.
Step 2 (high speed)
When the terminal “A“ (+10V) is connected with the input terminal “E“ or
“E1”, then the units supplies the output voltage set by “n-max.”
