2.5.2 Expansion modules
The SITOP CNX8600 expansion modules have a main operating area with potentiometers
(
①
and
②
) and an LED button
③
: The potentiometers are used to set the output voltage
and response threshold of the output current. The potentiometers can be individually set for
each output. The individual outputs can be switched-on and switched-off using the buttons;
further, each output can be manually reset after an electronic shutdown.

Function
①
Voltage
potentiometer "U (V)"
Sets the voltage of the relevant output; see Setting the output voltage
(Page 53).
②
Current
potentiometer "I (A)"
Sets the response threshold of the output current of the relevant output;
see Setting the response threshold value of the output current
(Page 54).
③
LED buttons
"ON/OFF/RST"
Switches in and switches out the various outputs, or resets the particu-
lar outputs after an electronic shutdown; see Switching-in and switch-
ing-out outputs (Page 55) as well as Overload shutdown and carrying
out a reset (Page 56).
Protection and sealing
The operating elements, with the exception of the buttons, are protected against
unauthorized operation by a transparent plastic cover. When required, this plastic cover can
be sealed to prevent the operating elements being actuated by unauthorized personnel. For
sealing, the sealing wire can be routed through an opening in the plastic cover and housing,
as shown in the diagram below.
