Electronic spacing device ELC1plus

The Hofmann ELC1plus is a line-spacing electronics control unit for self-propelled road marking machines, controlling up to 4 solenoid valve outputs — the standard configuration covers 2 paint guns and 2 glass bead guns simultaneously. The unit features a 2.8-inch color display and supports three distinct operating modes: manual marking (operator controls which guns are active and for how long), semi-automatic marking (operator sets gun selection and start point; line length completion is automatic per the programmed cycle), and fully automatic marking (the machine executes the operator’s stored program independently). Up to 10 line-gap programs can be stored simultaneously in memory. The system counts marking meters per gun and total meters across all guns continuously during operation. A parallel water-gap program runs simultaneously alongside the line-gap program. An optional keypad accessory allows up to 12 programmable shortcut keys for rapid access to frequently used program and gun output combinations. Integrated pump control is built into the unit. Compatible application techniques cover cold paint, 2K cold plastic, spray 2K cold plastic, thermoplastic, and spray thermoplastic.

The travel direction recognition function ensures that when the machine maneuvers — reverses, turns, or repositions — while mid-gap in a line-gap cycle, the ELC1plus correctly identifies the machine’s position in the cycle and resumes marking at the correct line-start point when the machine moves forward again. Without this function, repositioning during a gap would result in the next line starting at the wrong distance — producing irregular spacing across the full marking run. The ability to synchronously add or remove additional guns during a running line-gap cycle allows operators to switch between single-line and multi-line configurations within the same marking pass without stopping or reprogramming. The documentation sub-menu records operational data for marking output reporting and machine utilization tracking.

The Hofmann ELC1plus is installed on self-propelled road marking machines for broken line marking on motorways, trunk roads, urban arterials, car parks, and sports facilities — wherever line length, gap length, and gun sequencing must be electronically controlled and documented across extended marking runs. It is compatible across the full range of Hofmann cold paint, thermoplastic, and cold plastic marking machines.

Leader Infra supplies this multi-mode line-spacing control electronics unit for self-propelled road marking machines — delivering manual, semi-automatic, and fully automatic gun sequencing with travel direction recognition, 10-program memory, integrated pump control, and continuous marking meter documentation across all cold paint, thermoplastic, and cold plastic application techniques.

FAQ — What does the travel direction recognition function prevent during a broken line marking run? When a marking machine reverses or maneuvers mid-gap in a line-gap cycle — for example to avoid an obstacle or reposition — the ELC1plus tracks the direction of travel and maintains the correct position within the cycle. When forward travel resumes, the next line starts at exactly the correct distance from the previous line end, preventing the irregular spacing that would occur if the electronics simply resumed the cycle from where it was interrupted regardless of how far the machine moved while maneuvering.
