Application
The wall bracket allows separate mounting of actuator controls and actuator.
●
If the actuator cannot be accessed safely.
●
If the actuator is subjected to high temperatures.
●
In case of heavy vibration of the valve.
Information on installation with wall bracket
●
The permissible cable length between actuator controls on wall bracket and
the actuator amounts to 100 m maximum.
●
We recommend using an AUMA “LSW” cable set.
●
If the AUMA cable set is not used:
- Use suitable flexible and screened connecting cables.
- Use separate CAN bus cable of 120 Ohm character impedance for MWG
(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.
- Voltage supply MWG: XM6-XA6 = GND, XM7-XA7 = + 24 V DC (refer to
wiring diagram).
