In case of calibrating with the A-option, this value is self-calculated and it is recommended not to modify it so as not to overwrite the calibration data.

4.4 Alarm submenu

In this submenu you can set alarms. If a value is applied to the alarm, when that value is exceeded, the alarm will be activated and the state of the relay will change. The status of each relay can be confi gured individually as open or closed.

The LCKs incorporate alarm LEDs. These LEDs are not linked to the state of the relay but with the alarms.

Options submenu Description

Alarm 1: FULL LOAD.

Parameter to indicate the alarm level. If we set a value to the alarm, we enable it. When the load value is EXCEEDED, the alarm is activated and the relay will change

its state. When the alarm is active, the alarm LED will light up. If the set value is “00000”, this value disables the alarm and the relay will be deactivated.

Parameter to indicate the status of the relay. This parameter allows you to confi gure the status of the relay when the alarm is not active. Active relay, normally closed (by default). Inactive relay, normally open.

Alarm 2: OVERLOAD.

Parameter to indicate the alarm level. This parameter works the same as in alarm 1 but applied to alarm 2.

Parameter to indicate the status of the relay. Active relay, normally closed (by default). Inactive relay, normally open.

When the alarm is active, the alarm LED will light up. If the set value is “00000”, this value disables the alarm and the relay will be deactivated.

Parameter to indicate the status of the relay. Active relay, normally closed (by default).

Inactive relay, normally open.

4.5 Chain compensation submenu

In this submenu you can activate or deactivate the software chain compensation. This function allow to balance the weight gap produced by the elevator chain compensation on the cabin. To use this compensation function the control unit must be connected to HOLD signal (chapter 2.3). Once the compensation is confi gurated, after the HOLD signal activation, that occurs when the doors are closed, the control unit calculates the weight after the elevator stars traveling.

Cuando la señal HOLD se active con el inicio del viaje del ascensor, el display no cambiara, ni la salida analógica referenciada al display hasta que el trayecto del ascensor termine y se desactive la señal HOLD.

Submenu Options Description

Maximum value of chain compensation. Select a maximum value to compensate from 0 ... 600.

Compensated value of the chain by software estimation. (Read-only) Seconds to make an Auto Zero when the Hardware HOLD input is active, and the weight remains constant at least for this period of time.

Time to measure the weight before the HOLD signal triggers. This parameter is measured in tenths of a second and serves to be able to take a stable measure of the weight before closing doors.

Delay time to update the weight when the HOLD signal is released. This parameter is marked by tenths of a second and serves to be able to update a stable measure of weight after the opening of the doors.

LCK devices integrate a function called AUTO-ZERO, which is activated after selecting a compensation type (cid:31) and set a maximum compensation value (cid:31) .

This function is designed to automatically eliminate the possible error that may appear below the marking as the maximum compensation value. The AUTO-ZERO function will be applied when the device does not detect any weight change of more than 20kg for a period of time.

If the maximum compensation value is set to “00000” it will deactivate the AUTO-ZERO function.
