LED diagnostics
LED diagnostic table — colours × sequences
The maintenance manual maps each LED combination on the control box (colour, sequence) to the function or fault it signals, with an explanation.

Your challenges
The truck is on the lift. You have two minutes.
Friction points reported by European workshop managers working on DL-6 and AluLIFT.
Uncertain diagnosis of an intermittent fault
Without a clear LED map, a technician loses 15 to 30 minutes isolating the cause of a motor, sensor or electronics fault. The truck holds up the customer's entire logistics chain.
Ambiguous part identification
Part reference from a printed PDF catalogue, cross-checked against an engraved serial number: the slightest typo means the wrong part delivered and the truck off the road again at D+3.
No visibility on supplier stock
Call the sales rep, wait for the email reply: no way to promise the customer the truck back on the road this Friday without certainty that the reference is actually in stock.
No structured preventive plan
Without a 3 / 6 / 12-month maintenance schedule matched to actual use (cycles/day), wear parts (guide pads, balancer, motor unit) fail at the worst moment — often mid-route.
How VanDOOR responds
Four technical tools built for the workshop.
Sourced from the official DL-6 and AluLIFT maintenance manuals — available now.
Part identification
Spare-parts catalogue with explicit compatibility
Each part reference shows compatibility (DL-6 / AluLIFT / both), stock status, indicative lead time and price. No more cross-checking two PDFs.

Preventive maintenance
3 / 6 / 12-month plan based on 10,000 cycles/year
Each maintenance window's operations and the references to keep in stock, for a fleet running 40 cycles/day: DL-8001254 guide pads replaced yearly (set of 4), balancer every 1.5–2 years, motor unit at 5 years.

Workshop FAQs
Field reflexes, in five questions.
Five questions sourced from the DL-6 and AluLIFT manuals — emergency release, guide pads, balancer, battery.
The FOB remote runs on an A23 dry-cell — 12 V, replace if range drops or the remote becomes intermittent. Replacement is scheduled at the annual service. Universal reference available in retail. No specific tooling required.
External release procedure: (1) insert the DoorLIFT key into the lock cylinder at the centre of the intermediate or top panel, outside face; (2) turn the key 90° clockwise and firmly pull the lock and cable out of the cylinder — the system disengages; (3) reinsert the cable and cylinder into the door lock housing, then operate the door by hand. On the AluLIFT, an internal release is available: pull the red sleeve marked 'EMERGENCY DOOR RELEASE' to disengage the motor lever from inside the box.
The official schedule mandates an inspection at 3 months (AluLIFT only), at 6 months (DL-6 and AluLIFT), and annually (both). Calculation basis: 40 cycles per day, 5 days per week — about 10,000 cycles/year. For heavier usage, scale inspection frequency accordingly. DoorLIFT service must always be performed alongside the door's own service. Time budget: 30 minutes for the half-yearly service, 60 minutes for the annual service.
Never apply grease or oily product to the DoorLIFT system. Grease coats surfaces and attracts dust, dirt and salt — accelerating wear on pinions and guide blocks. Clean only with a damp cloth. Do not use volatile substances: static electricity can ignite them. However, do lubricate the hinge axles, drum bearings and balancer springs of the door itself (not the DoorLIFT). Also lubricate the emergency-release lock at every 3-month service.
The four guiding blocks (ref. DL-8001254) must be replaced at every annual inspection. They are the highest-frequency consumable in the system — one system = four blocks per year. Replacement is explicitly listed in both ranges' maintenance schedules (DL-6 and AluLIFT). The part is common to both. Keep a few sets in stock at the workshop if you operate more than 5 equipped vehicles.
