•
Or instead use an external +12V - +15V/@
12VA power supply close to the MC 4000. The
+15V supply in the cable(s) from the central
unit(s) must be cut. See drawing 4.6-90 in the
appendix for connection of this.
•
One CU 4005/CU 4010 can only power one
MC 4000. If two are needed, one unit must
have external power supply (see above).
•
If two MC 4000 units are needed in the end of
the control link, the last MC 4000 must have
external power supply (see above).
•
It is possible to have an MC 4000 in both ends
of the control link. But the MC 4000 connected
to PREVIOUS (of the preceding CU 4005/CU
4010) must be connected to its female
connector in the bottom of the unit. The cable
with the male connector can be rolled up, or it
can be removed from the unit:
Take off the bottom parts of the unit (6
screws. Note their sizes).
Cut off the plastic strips holding the cable
and pull out the cable plug.
Replace bottom parts and screws.
•
The MC 4000 have two M4 holes in the bottom
for fixation of the unit on a table. Note that the
screws (M4) only can go approx. 5 mm into the
unit.
•
The MC 4000 can also be flush mounted in a
table: Remove bottom parts and sides of the
unit. (See above.) There is a hole in each corner
of the metal front plate (under the acrylic
front). Use these for centre marks and drill four
holes from the backside. Take care not to burst
the rim of the holes in the acrylic front. It is
recommended to counter sink the screws in the
front and to use black counter sunken screws.
Can be ordered from DIS.
RS 4232 Serial Communication Module
•
A maximum number of two RS 4232 modules
can be installed in a system. The module is
easily installed inside the backside of the CU
4005/CU 4010. Any two CU 4005/CU 4010
units in a system can have a module built in.
•
Both the RS232 and the RS 422 serial ports can
be used simultaneously. A maximum of four
external computers or other serial devices can
thus be connected to a system. If only a single
CU 4005/CU 4010 is present, the maximum
number is two serial devices (one RS232 and
one RS 422).
•
NOTE: Both ports use a data rate of 9600
baud, 8 bits, No Parity and 1 stop bit. The
RTS/CTS handshake signals are in use.
•
RS232 cables should not be much longer than
10 m (max. 20 m).
•
For RS232 a flexible cable of minimum 5x0,25
mm
2
(min.
5
leads)
with
screen
is
recommended.
•
RS 422 cables can be up to 1000 m.
•
For RS 422 a flexible cable of 5x2x0,25 mm
2
(min. 5 pairs) with screen is recommended.
CU 4005/CU 4010 Central Units
•
The central units can be placed on a table or in
a 19-inch rack.
•
Do not stack more than two units on a table.
•
Do not remove rubber feet.
•
There should be adequate ventilation, when
placed in a rack. Have one height unit between
each central unit, and one height unit under the
bottom unit and over the top unit. Forced
ventilation might be necessary; and there must
be free airflow through the ventilating holes of
the central units.
