RolloTec cutoff relays RMD are snapped onto the DIN hat profile rail.272 kΩ 25 33.28 W Switches, 1-pole ON/OFF Contacts (relay) contact (for heating) not potential-free Temperature lowering approx. °C Sensor element NTC Sensor cable PVC 0.785 kΩ 15 52. For joint control, use Berker cutoff relays electronic tubular motors, such those from Becker, Elero Selve.137 17.

RolloTec cutoff relay RolloTec cutoff relays are mounted water-protected junction boxes or in deep flush-mounted sockets, e.

Weld the contacts. Provide additional miniature circuit- breakers for extensions. 2034. These switching operations cause pendulum motion the roller blind.

Figure Parallel-switched conventional tubular motors When the switch actuated, both drives are switched for the same running direction.3 kW Power consumption with night lowering 0.33 41. – The following variants are available, depending the operating concept – RolloTec cutoff relay [2930] and RolloTec cutoff relay RMD [2931] for simultaneous movement two motors using one control section – RolloTec cutoff relay [2969] and RolloTec cutoff relay RMD [2919] with extension circuits for simultaneous movement two motors using one control section separate operation the individual motors. shut again after short time. Since the feedback voltage can 1000 and many switching position changes occur very short time, the limit position switch E2 overloaded. When laying the cable ducts when close high current conductors, shielded wires should used.14 W 0.T35 The sensor cable can, necessary, extended using 2-wire cable of 1.281 kΩ 35 21. When drive has reached the limit position, the limit position switch opens. The motors are destroyed.846 11. Drive can still functioning, however, and actuates drive the opposite running direction means a feedback voltage via its capacitor. The limit switch disabled this running direction.279 66.00 26. 1 Drive 1 2 Drive 2 3 Junction box with cutoff relay 4 Junction box 5 RolloTec control section 2+PE 3+PE 5 4 3+PE 4+PE34 5 2 1 Figure Installation plan for cutoff relay Thermostat RolloTec cutoff relay .
