Product description
3.1
Functional description
The comfort handle functions as a door latch, handle lever monitor and visual LED status display. A
40 mm semi-cylinder to DIN 18 252 serves as the master key. This can be used to open the handle
in an emergency. If the lever handle is closed, the latch mechanism integrated into the comfort handle
locks automatically.
The handle can be incorporated into the CMC III system. This requires a CMC III Access Control
(DK 7030.202) which is attached near the door in conjunction with a base system. An example of a
base system might be a CMC III Processing Unit (DK 7030.000), a CMC III Processing Unit Compact
(DK 7030.010), a Rittal IoT Interface (SK 3124.300) and a Rittal PDU (DK 7979.xxx, except PDU
basic). In such cases, the handle can be released via the base system or using additional optional
systems such as a coded lock (DK 7030.222/.223) or transponder reader (DK 7030.232/.233). The
comfort handle has an identifier enabling it to be detected automatically by the base system.
Alternatively, the opening of the comfort handle can also be controlled via an external controller. In
such cases, the external controller provides both the supply voltage and the signal for opening the
lever handle via the PLC interface.
3.2
Proper use
The CMC III online comfort handle VX is only used for locking the door and monitoring the lever han-
dle. It may only be used in conjunction with a base system and, where applicable, the Access Control
(DK 7030.2020) or alternatively with activation via the PLC interface. Any other use is not permitted.
