Frames with USB connector: It is recommended to screw a typical 4-40 UNC DSUB
locking bolt into the thread as shown. Unlock the module: on the right hand side of
this small slot there is a small protruding tab that needs to be slightly pressed to the
right. Now pull the module out of the slot.
This module is equipped with the fan and the fan control electronic, furthermore with a fail
relay for error detection, a fourfold dip switch and a rotary switch.

The contacts of the fail relay are normally open during operation, but close if this module or
the fan has a failure. The contacts are (in parallel with the fail relays of all modules plugged
into this frame) connected to the FAIL_A and FAIL_B pins of the RLC connector of the frame.
Please notice: The fan alarm will be raised only if there is one configurable module plugged
into this frame with checkbox “
Fan monitoring
” checked!
The fourfold dip switch can be used to terminate the “TC_link” interface (RS485 bus) of the
RLC connector. In a system of one or two frames all the switches should be set to position ON
(= terminated). In a system of more than two frames the switches of the first and the last frame
should be set to position ON, all other to position OFF.
The rotary switch sets the frame number. A system of one frame only gets number 0 (=
single). In a system consisting of more than one frame the rotary switches should be set to
numbers > 0 in that way that each frame gets a unique number.
