Practical examples (Mainz/Wiesbaden)
Replacement of folding wedge ramps in Mainz
Old unit, unclear wiring: With RS 301 K + CS 320, the bridge, including shelter locking, could be put into operation in accordance with standards – Auto-Return automatically lowers the bridge after loading.
Feed lip in Wiesbaden
New construction with 3-phase supply line: RS 301 V with 3 direction buttons and 8 valve versions, plus 24 V supply for traffic lights/sensors – clear operating logic for drivers and logistics.
FAQ – Industrial Gate & Ramp Controls
What is the difference between RS 301 K and RS 301 V?
K = Folding wedge bridges (4 valve versions, lift/auto-return operation); V = Telescopic lip bridges (up to 8 valve versions, lift/forward/back/auto-return operation).
When should I choose CS 320 in 230 V vs. 400 V?
230 V (Schuko) for single-phase supply; 400 V (CEE) for three-phase drives or higher loads. Optionally with integrated main switch.
Do I need a module for additional functions?
Yes – e.g. EM 172 for two-way traffic control (4 I/4 O) or EM 184 for 2 entry protection devices.
Is there an emergency power solution?
Yes, the 230 V emergency power buffer (2000 VA) keeps the control system temporarily operational in the event of a power failure.
Which 24 V supply makes sense?
In the control cabinet: DIN rail power supply (66.7 W). Outdoor/compact: IP65 CS mini housing with 1.5 m Schuko power cable.
Where can I find all ramp/industrial gate controls?
In our collections: Marantec industrial door controls and loading technology controls .
