FAQ LIST

Question: If several JRMs are used within one system, can the central UP/DOWN function be activated jointly (parallel)?
1
Answer: The central UP/DOWN function may not be connected in parallel. A potential-free relay must be used.
Question: How can I operate more than one JRM with the one sensor?
2
Answer: Sensors can be used for more than one JRM via the compact bus (see page 24).
Question: Can more than 12 motors be connected to the 952 JRM?
3
Answer: Yes, for example with the help of the 409 SR multiple control relay.
Question: How can I prevent the shutter on the terrace door from closing whilst we are sitting outside?
Answer: The motor's auto mode can be switched ON and OFF at a switch on input I32. The affected motor must be assigned to input I32 in the
4
AUTO device menu. Auto mode extends to the twilight sensor, sun sensor, and timer.
Caution: Timer commands are not repeated.
Question: Do the 0V terminals on the inputs have to be wired in a star pattern or can they be connected in parallel?
5
Answer: The 0V terminal that is closest to an input should always be used. Parallel connection is also permitted. Observe the length and dia-
meter of the wires (approx. 400 m when d= 0.8 mm)!
Question: How are the outputs (relays) protected, or are internal fuses fitted upstream of the relays?
6
Answer: The connecting cables for supplying power to the outputs (L0-L3) must be protected with a 10 A automatic circuit breaker.
Make sure the loads and the power consumption (230 V~ /50 Hz /1A) are evenly distributed!
