INSTALLATION DE LA COMPENSATION DES CÂBLES
1.1 Principe de fonctionnement
Le principe de fonctionnement est que le poids des câbles s’ajoute ou se soustrait au poids de la cabine d’une manière
proportionnelle au parcours de la cabine dans la gaine. Il suffit donc d’installer un détecteur composé par un "lecteur
magnétique", placé sur le toit de la cabine.
Le système ne nécessite pas de course d’apprentissage, et en plus il n’est pas nécessaire de paramétrer le système pour la
compensation des câbles, puisque il suffit de ne pas brancher le détecteur de compensation quand on ne veut pas l’utiliser.

ERROR CODES
6.1 Error code E3
Description: Error of programmed reference weight in the calibration (reference weight < 1/3 of the overload weight
threshold 2).
What to verify: Make sure that programmed reference weight is exactly > 1/3 of the imposed overload weight:
1. Press "ESC" button until the "WEIGHT" LED is on.
2. Press "PROG" button until the "WEIGHT" LED flash on.
3. Verify that the shown value is exactly > 1/3 of the imposed value.
What to do: Repeat calibration starting from paragraph 4.1.5 making sure that the programmed reference weight is
exactly > 1/3 of threshold 2 (overload).
6.2 Error code E2
Description: Error of used reference weight (as required at point number 4 of paragraph 4.1.5). It happens when the
reference weight is too small (reference weight missing or device not tightened etc.).
What to verify:
1. Make sure that the LLEC5F is correctly tightened.
2. Make sure that the correct reference weight has been loaded, during the weight calibration.
What to do:
1. Correctly tighten the LLEC5F as described in the calibration procedure (chapter 1).
2. Repeat calibration starting from paragraph 4.1.5 making sure that the used reference weight is exactly > 1/3 of
threshold 2 (overload).
6.3 Error code E4
Description: Error of internal compensation (the maximum or minimum limit for compensation has been reached). The
compensation function operates when the display shows a different value than "0" for more than 3 minutes and also,
during that time, the value is not changed; the execution foresees the modification of the "variable of compensation" for
the display to show "0". The main causes that can influence the compensation are :
1. VARIATION IN TEMPERATURE :
What to verify: Make sure that you did the temperature setting (paragraph 4.1.1, point 2).
What to do: Make the Calibration Procedure again, starting from paragraph 4.1.1.
2. FRICTIONS INFLUENCING THE MEASURE :
What to verify: Check if there are mechanical frictions in the installations that could influence the measure and if so,
reduce them at the minimum possible.
What to do: Make the Calibration Procedure again, starting from paragraph 4.1.1.
3. TOO HEAVY CABLES :
What to verify: If cables are too heavy, this can influence the measure of LLEC5 system.
What to do: Replace the LLEC5 unit with the one with cable compensation option.
4. WRONG ADDED OR SUBTRACTED WEIGHTS (i.e.: weights left inside the lift car = wrong added weights / lift car on shock
absorber = wrong subtracted weights) :
What to verify: Check that no weight has been left or added inside the lift car (paragraph 7.1).
What to do: Take away these weights and make the Calibration Procedure again, starting from paragraph 4.1.1.
Note: For any other error code please contact DMG SpA. Warnings/fails are automatically deleted as soon as the
error has been eliminated.

MAINTENANCE INFORMATION
7.1 Absolutely forbidden to leave weights in the cabin
LLEC5 has a compensation system that permits a zero setting of some errors caused by temperature variations, friction of the car
guide rails, etc.
Fixed weights (lower than 25% of full weight programmed in advance) let in cabin cause a system trouble to compensate.
Compensation begins when system, with weight in the cabin and without other weight variations has not been in use for more than
3 minutes.
The weight in cabin will be compensated within 15-20 minutes, after this time LLEC5 won't note the weight inside the lift and it will
begin to weight as zero setting.
In this case also the unloaded threshold won't correspond to the one programmed previously because it heights with the
compensated quantity in cabin.
EX: If unloaded threshold has been calibrated for 600 kilos and in cabin has been left a weight for 140 kilos for more than 20
minutes and without using the lift, it will compensate the 140 kilos.
7.2 Controls after checking the parachute
After the periodic checks on the parachute, it is advisable to control again the calibration of the system and the mechanic fixings,
as the mechanic stress on the structure may modify the unit's fixing.
