Do you have a question about the SOMFY J4 WT and is the answer not in the manual?
Simultaneous UP/DOWN operation is disallowed, except in programming mode.
Each drive should be controlled from a single source.
Maintain a 500ms pause between UP/DOWN commands.
Drives have a 180ms wake-up delay, consider for short commands.
Avoid activating WT drives at end limits for >4s in bus systems (set <4s overtravel).
Multiple WT drives can be paralleled using electronic limit switches.
Connection cable length for WT drives must not exceed 50 meters.
Voltage on the inactive direction terminal must not exceed 55 V rms.
Do not operate Somfy WT drives with solid state relays.
In KNX systems, the neutral conductor must connect to the actuator/motor output.
The neutral conductor connection serves as a measuring point for the actuator.
J4 18 WT drives cannot be operated via an isolating transformer or with frequencies >63 Hz.
