Wireless crane remote control | 2 buttons + START, magnetic key | 1 speed | 24–440 V AC/DC | IP65 | EL-F21-2S-TX

Wireless hoist remote EL-F21-2S-TX – ▲ / ▼ + START, 24–440 V AC/DC receiver

EL-F21-2S-TX is the simplest radio remote for one motion axis: raising and lowering. The transmitter command reaches the receiver by radio, and its relays energise the hoist-up or hoist-down contactor coil.

• ▲ / ▼ buttons – raising and lowering
• START – the main contactor is switched on by a deliberate action
• Magnetic safety key – quick transmitter shut-off, protection against unauthorised use
• Battery monitoring – the transmitter switches off at low voltage
• 24–440 V AC/DC IP65 receiver – mounted on the machine
• 130×45 mm transmitter – fits in a pocket

• ES-F21-2S+ – Also 2 direction buttons, but with a mushroom STOP button.
• ES-ML-K2 – 2 buttons, 868 MHz, 230 V AC receiver, IP66 – when the control circuit is 230 V AC.
• LCC-202 – 2 two-step buttons – for 2-speed hoisting.
• ES-F21-E1-TX – 6 direction buttons + START/STOP – for a 3-axis crane.

• Electric hoists without a trolley
• Construction winches
• Goods lifts in warehouses and farms
• Small lifting beams in workshops
• Replacing a 2-button pendant

• The receiver relays switch the contactor coils, not the motor directly – relay contacts are for the control circuit only.
• The receiver supply voltage must match the control circuit (coil) voltage; range 24–440 V AC/DC.
• Wire the STOP / MAIN relay so that it drops out the main contactor KM0. Loss of radio link must stop the crane (EN 60204-32) – test this during commissioning.
• Limit switches (SQ) and the NC interlock between opposite directions stay in the circuit – the radio remote does not replace them.
• For crane repairs, apply LOTO on the main isolator. The STOP button is not isolation from the supply.
• At commissioning, check that removing the magnetic key or switching the transmitter off makes the receiver drop the MAIN relay and the movement stops.

Quick selection guide

Check before ordering:

• Contactor coil voltage is within 24–440 V AC/DC and equals the receiver supply.
• Radio frequency of the set (EU SRD bands – 433 / 868 MHz) – check that the frequency is permitted in your country.
• Whether one axis and one speed are enough, and whether a key instead of a mushroom STOP is acceptable.

EL-F21-2S-TX – single-axis radio remote with magnetic key

▲, ▼ and START in a compact transmitter, a magnetic safety key and an IP65 24–440 V AC/DC receiver. For hoisting or a winch without a complex circuit.
