CAME E2 on garage door opener: incomplete travel calibration
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
Error E2 (shown as E 2) on CAME VER06DES and VER08DES overhead garage door openers means travel calibration is incomplete. Never touch springs or lifting cables; check that the doorway is clear and have a qualified installer run the A3 travel calibration.
Safety first
Stop and check this first
- Springs, lifting cables, brackets, and counterweights on sectional and up-and-over garage doors are under extreme tension and can cause severe injury or death: keep clear and never attempt to adjust, release, or repair them yourself.
- During Travel calibration (function A3), all safety devices are disabled except TOTAL STOP (F1): only a qualified installer may perform calibration while keeping the manoeuvring area completely clear.
Safe checks you can perform
- Confirm the garage door manoeuvring area is clear for E2
- Check that no manual door bolt or latch is engaged
- Visually inspect from a safe distance without touching springs or cables
Leave these tasks to a qualified professional
- Do not attempt this professional task: Run function A3 (Travel calibration) and complete the self-learning cycle
- Do not attempt this professional task: Inspect door mechanical balance and the guide rail calibration microswitch
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Run function A3 (Travel calibration) and complete the self-learning cycle
What they doWith the operator stopped, the installer enters function A3 (Travel calibration), uses > to set the opening limit (OP), presses ENTER, uses < to set the closing limit (CL), presses ENTER, and lets the operator run a full travel cycle to self-learn sensitivity values.
They must show youthe complete A3 travel calibration sequence on the CAME VER display and confirmation that error E 2 clears afterward.
In writingthe recorded opening (OP) and closing (CL) limit positions in A3 and verification that the encoder travel test succeeded.
Inspect door mechanical balance and the guide rail calibration microswitch
What they doThe technician checks that the guided door is in good mechanical condition and balanced, and verifies the position and NO - C connection (terminal 12) of the calibration microswitch on the chain or belt rail.
They must show youthe calibration microswitch installation on the guide rail and smooth, balanced movement of the garage door.
In writingthe inspection results for the calibration microswitch, guide rail, and mechanical balance of the door.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Confirm the garage door manoeuvring area is clear for E2
- Who:
- you, with the overhead opener stopped and remote controls set aside.
- How:
- inspect the floor and overhead path of the sectional or up-and-over door to verify that no vehicle, shelf, box, or tool blocks the travel area.
- Result that matters:
- ensure the manoeuvring area has no obstacles before the installer performs travel calibration.
- If an object was in the travel zone:
- move it out of the way while the door is stationary before calling the installer.
- If the entire opening and closing path is clear:
- check next that no manual door bolt is engaged.
- Evidence to keep:
- confirmation that the garage doorway and overhead track path are clear of obstacles.

Check that no manual door bolt or latch is engaged
- Who:
- you, standing inside the garage without touching springs, pulleys, or cables.
- How:
- verify that no manual slide bolt, rope, chain, or mechanical latch on the door leaf is engaged and preventing full travel.
- Result that matters:
- make sure no manual lock is stopping the CAME VER opener from completing its stroke.
- If a manual latch was engaged:
- release it only while the door is resting fully closed on the floor.
- If no manual locks are engaged and E 2 remains displayed:
- proceed to the safe visual check from the floor.
- Evidence to keep:
- status of any manual bolts or latches on the sectional or up-and-over door.
Evidence: CAME VER06DES and VER08DES Sectional and Up-and-over Door Operator Installation Manual (FA02221-EN)
Visually inspect from a safe distance without touching springs or cables
- Who:
- you, standing safely on the floor without climbing a ladder or touching hardware.
- How:
- look at the side tracks and door assembly from a distance to spot any obvious issue without placing your hands near torsion springs, lifting cables, pulleys, or counterweights.
- Result that matters:
- check visible door condition safely without touching high-tension counterbalance parts.
- If tracks and panels look intact from the floor but E 2 stays on:
- book a qualified installer to run function A3.
- If you see a slack cable, broken spring, or bent track:
- stay away from the door, do not pull the manual release, and call a professional immediately.
- Evidence to keep:
- visual check from the garage floor and the E 2 message shown on the CAME VER display.

What it means
In the CAME VER06DES and VER08DES encoder operator installation manual for sectional and up-and-over garage doors (FA02221-EN), error message E 2 indicates Calibrating the complete gate-travel (incomplete travel calibration). The control board requires setting the opening (OP) and closing (CL) limits and completing a full travel cycle in function A3 (Travel calibration) to self-learn sensitivity values, as well as properly wiring the calibration microswitch when the motor head is mounted perpendicularly on the guide rail. Other CAME models may differ, and E2 alone never proves the encoder or control board has failed.
