10.5 Example applications
10.5.1 General
Note: Switching the DC output on when it is initially off does not
work if remote control is not active.
Note: A digital output of a PLC or any other controlling applica-
tion may not be able to pull inputs like REMOTE or REM-SB
to LOW. Refer to the technical specications of the particular
hardware for details.

10.5.2 Output off/on
Note: Pin REM-SB is not depending on remote control being
active and can switch off the DC output at any time resp. inhibit
to switch it on, except the device is in LOCAL mode. During
LOCAL mode the device can only be controlled manually. See
section 6.9 about LOCAL.
Switching the DC output of the device off is either done with
LOW or HIGH level on the pin 13, REM-SB (input). This depends
on the settings related to the analogue interface in the device
setup (see section 10.3).
Attention! This pin is internally pulled up to HIGH. When selec-
ting HIGH in the setup menu for this pin, the function „output
off“ would be permanent and would require to pull the pin to
LOW rst, in order to be able to manually or digitally control
the DC output.
Condition LOW can be achieved by using a low-resistive contact
like a switch, open collector transistor or relay.
