5.4.
Accessories for electrical connection (option)
5.4.1 Controls mounted to wall bracket
The controls can also be mounted separately from the actuator on a wall
bracket.
Application
.
If there is no proper access to the actuator/local controls
.
In case of heavy vibration of the valve
Design
Observe prior to connection
.
Permissible length of connecting cables: max. 100 m.
.
Permissible length of connecting cables for later separation of actuator
and controls: max. 10 m.
.
We recommend: AUMA cable set LSW21-KES or LSW22-KP.
.
If not using an AUMA cable set, the following has to be observed as well:
–
Use suitable flexible and screened connecting cables.
–
Use separate, CAN-capable data cable for MWG of 120 Ohm intrinsic
impedance (e.g. UNITRONIC BUS-FD P CAN UL/CSA - 2 x 2 x 0.5
mm², manufacturer: Lapp).
–
Data cable connection: XM2-XA2 = CAN L, XM3-XA3 = CAN H.
–
MWG voltage supply if the AUMATIC has been ordered and delivered
with wall bracket: XM6-XA6 = GND, XM7-XA7 = + 24 V DC (refer to
wiring diagram).
–
MWG voltage supply if AUMATIC has been subsequently separated
from the actuator: XM6-XA6 = GND, XM11-XA117 = + 5 V DC (refer to
wiring diagram).
.
If connecting cables, e.g. of the heater, are available requiring direct wir-
ing from the actuator to the XK customer connector (XA-XM-XK, refer to
wiring diagram), these connecting cables must be subject to an insula-
tion test in compliance with EN 50178.
The connecting cables from the MWG may
not
be subject to an
insulation test.
