S-Drive Motor - E-Rail System

S-Drive Motor - E-Rail System

We developed the S-Drive system specifically aimed to be used in schools and small venues. Offering the same convenience in regards to track mounting the S-Drive offers the perfect solution when space, weight and budget are restricted.

The S-Drive specification is as follows:

1)  Maximum curtain weight: 75kg on straight track, 50kg on curved track
2)  Maximum linear speed: 0.7m/s

Designed into the S-Drive unit was exceptional ease of installation, hence it only requires the hard wiring of the power cable into the mains supply (230VAC, 50Hz) plugging in of end-of-travel limits and control pendants. The power connection is realised with a Neutrik PowerCon, the control inputs are connected via the following XLR connections:

1)  1 x 4 pin XLR for 3 push button wired pendant (standard control option) or 3 push button pendant with key lock (optional pendant)
2)  1 x 6 pin XLR for additional pendant with speed control
3)  2 x 3 pin XLR for track mounted limits

The standard control pendant has open, close and stop functions and includes a standard XLR connector for adding an optional second pendant for use either on stage or in a control room. The wireless pendant option can be combined with any wired pendant.
For convenience we furthermore incorporated a motor reverse switch that allows the user to correct the curtain operation direction in relation to the control buttons
The S-Drive motor uses a 0.12kW 50Hz motor and requires a 230V, 13Amp, 50Hz single phase supply.

S-Drive – in Detail

The S-Drive is a compact motor unit incorporating all drive and control elements in one compact assembly. With its compact dimensions and small weight of only 15kg it is easy to install and due to its plug and play configuration quick to get running. The following chapter will give you information on how to set up and maintain an S-Drive motor unit.

The S-Drive motor unit is specifically designed for our E-Rail system and can be mounted onto straight or curved curtain track set ups. For straight track systems the motor needs to be suspended from the ERL17 mounting bracket, for curved lay outs the mounting bracket ERL23 has to be used. An offset overlap for improved overlap of the curtain when closed is available for curved and straight track configurations.

The S-Drive unit is a maintenance free system; periodic checks should be made for loose components. As we use cord for the power transmission it may be necessary from time to time to re-tension the cord, as the cord is likely to stretch when being exposed to tensile load. To compensate the elasticity of the cord our S-Drive is fitted with a spring tensioning system. The cord may need replacing depending on how often the system is used and loads are applied.

The S-Drive unit can only be used to motorise curtains. The two mounting options, curved and straight track, result in two options for the limit mounted direct struck limits shown in the following pictures. A motorised track system has to be fitted with two limit switches one for the open and one for the close direction. The limit switches serve a very important function, they ensure the correct stopping points for curtains or scenery and also stop the motor running. By placing them correctly on the track they will stop the curtain in the fully open or fully closed positions. The position of the limit switches on the track must therefore take into account the operating speed of the motor.
