speed sensors are continuously
checked on operating within the
permitted limits.
Moreover, the channels mutually
check and supervise the output
signals of each other. If the internal
fault detection circuit detects an error,
this will be indicated via the output
contacts and shown on the display as
plaintext.
By means of the the PROFIBUS DP
interface the recorded data can be
passed on to host computers.
By using prefabricated connection
cables and screw terminals, the
systems may be integrated
economically in 19“ cabinets.
For the measurement of speed and
for the protection from overspeeds,
epro offers three system variants.
System DOPS
This system offers a maximum in
functionality and is certified
according to SIL3 – DIN EN 61508
in combination with epro MMS
eddy current measuring chains. It
requires the following components:
- 3 x monitor MMS 6350 (/DP)
(incl. firmware applic. no. 0)
Profibus-interface (optional)
or alternatively
- 3 x monitor MMS 6350D (/DP)
(incl. firmware applic. no. 0)
with speed display
Profibus-interface (optional)
In addition:
- 1 x Backplane MMS 6351/00
- 1 x 19“ frame MMS 6352
- 6 x screw terminals MMS 6361
- 6 x cable 0.5 m MMS 6362
alternatively
cable 3 m MMS 6360
- 1 configuration kit MMS 6950
- 3 x blind plate BLE 008, for the
installation of monitors without
display
When using this system line, there
are additional combinations
available via relay outputs beside
the normal outputs of the alarms
OUT1....OUT6 and the system
supervision Channel Clear:
2 v 3 combination output OUT1
2 v 3 combination output OUT2
2 v 3 combination output OUT3
2 v 3 combination Channel Clear
