The X4 Auto-Motion: no limit switches,
no safety edge.
The X4 Auto-Motion is a patented 115/230V motor-control system for sectional overhead doors. The limits are set electronically at the end of the door's travel, so there are no limit switches to fit or adjust, and a part-open position is easy to set. Built-in Safety Sense means the door operates without a safety edge.
- Patented design
- All settings from a mobile phone
- Full open & full close
- Built-in Safety Sense
- Doors up to 45 m²
- Over 17,000 test cycles
One forklift transmitter. Many doors.
The 4244 mounts next to the driver's seat with no wiring, so there are no more lost or broken hand transmitters. Paint a coloured spot on each door to match the buttons and a single transmitter can open more than four doors across the same site. Its battery should last more than 10 years.

Frequently Asked Questions
Do the X4 door operators need limit switches?
No. The limits are set electronically at the end of the door's travel, so there are no limit switches to fit or adjust. The door runs to full open and full close, and a part-open position is easy to set. All settings can be adjusted using a mobile phone.
Do I need to fit a safety edge?
No. The X4 Auto-Motion and X4 Solar operators have built-in Safety Sense to meet international safety standards including UL325 and CE, and they operate without a safety edge.
Which doors do the X4 operators suit?
Sectional overhead doors. The SPA models suit standard lift and high lift doors up to 16 m². The SPB, HPC and HPD models suit standard lift, high lift and vertical lift doors up to 25 m², 33 m² and 45 m² respectively.
How does the solar-powered operator charge?
A solar panel charges the lithium battery pack in the control unit. It will recharge the batteries within a few minutes, even under a dull, overcast sky. A separate plug-in charger is supplied as well, in case the batteries have been in storage for a long time.
Is cable included with the solar kit?
The kit includes the solar panel with adjustable wall or roof brackets, the control unit with battery pack and motor-controller, and the DC motor drive unit. The cable from the solar panel junction box to the controller is not included; use 5A rated cable.
How can one forklift transmitter open more than four doors?
Paint a coloured spot on each door: red for doors 1, 5, 9 and 13, yellow for 2, 6, 10 and 14, green for 3, 7, 11 and 15, and blue for 4, 8, 12 and 16. Each door's receiver is wired to the matching channel. Every fifth door is likely to be out of range of the first, and each door should be programmed to auto-close so a wrong button press can't close the wrong door.
How many transmitters can a receiver remember?
The 4221 single channel and 4222 two channel receivers have memory for 300 transmitter codes. The 4224 four channel receiver stores up to 30.
