Chain compensation submenu.

Only for models with CANopen-Lift CIA 417, see section 1.2.

CanOpen submenu.

Submenu of analog output. Only for models with analog output, see section 1.2.

Submenu for displaying the signal of the sensors in mV/V.

4.2 Information submenu

In this submenu you will find important equipment information and reset operation to restore the device to the factory state.

Options submenu Description Firmware Version (Read-only). The device will show the firmware version of the RCU unit.

Valid values: 1.00 and higher. Hardware Version (Read-only).

The device will show you the hardware version of the RCU unit.

Unit voltage (Read-only). Valid values around 24 VDC.

Reset operation. Restoration of the equipment to the factory state, select: To cancel the operation. To restore all values to the factory state. All calibration information will be lost.

4.3 Calibration submenu

In this submenu you will find different parameters and operations that will help you adjust the equipment to obtain the highest possible measurement accuracy.

Options submenu Description

The Operation to indicate zero. This operation must be performed with the elevator cabin empty. Inside the display will show you a value in seconds, this value will allow you to start a countdown to be able to perform the operation without any weight inside the elevator.

Parameter to indicate a known weight. To display the weight it is recommended to place inside the elevators cabin a known weight of 60% of the maximum load capacity. Then indicate and confirm the value of that weight.

Sensor sensitivity. (Option-B End Calibration) If the load cells are plug & play (factory adjusted), it would be possible to perform a calibration without indicating a known weight in the “Load” parameter. This type of cells will have the value of Cell indicated on its label or in some type of attached document, which must be entered in this parameter. In case of connecting a set of cells to the equipment, you must add all the cells and enter the total. Only if the sensors are installed on the cables or on the elevator belts and the suspension is different from 1:1, you must multiply the sum by the type of suspension x2 (2:1), x3 (3:1) etc.

Example: if we have connected 3 load cells with a value of Cell=500 installed in the elevator cables with a 2:1 suspension, the operation would be: (500+500+500)x2=3000 In case of calibrating with a “Zero” and a “Load”, 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 configured individually as open or closed.

No alarm will be activated as long as voltage is supplied to the HOLD input (e.g. travel signal or door closing).

Options submenu Description

FULL CHARGE alarm.

Parameter to indicate the alarm level. If we apply a value to the alarm, we enable it. When the load value is exceeded, the alarm is activated, and the relay will To cancel the operation. change it ́s state. When the alarm is active, the alarm LED To restore all values to the factory state. indicates. If the value set is “00000”, the alarm and the relay will be deactivated.

Parameter to indicate the status of the relay. This parameter allows you to configure the relay status concerning the alarm when it is deactivated. Normally open (set by default). Normally closed.

OVERLOAD alarm.

Parameter to indicate the alarm level. This parameter is the same as that of the COMPLETE LOAD

alarm but applied to the OVERLOAD alarm.

Parameter to indicate a known weight. Parameter to indicate the status of the relay.

This parameter is the same as that of the COMPLETE LOAD alarm but applied to the OVERLOAD alarm.

EMPTY CABIN alarm.

Parameter to indicate the level of the alarm. If we apply a value to the alarm, the alarm will be activated the measured weight is below this value.

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 2.1). Once the compensation is configurated, after HOLD signal activation, that occurs when the doors are closed, the control unit calculate the weight after the elevator travels.

When the elevator starts running and HOLD signal turns on, the display will not change, neither the analog output connected to the display until the run is over and HOLD signal deactivates.

Submenu Options Description Parameter to select the type of chain compensation. Within this parameter you can select:

Compensation via software. No chain compensation.

Maximum value of chain compensation. (For hardware and software). Select a maximum value to compensate from 0 ... 600.

AUTO-ZERO seconds (Time). Seconds programmed so the control unit make itself a ZERO when weigh don ́t vary ± 20kg.

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

Previous time to measure the weight before the activation of the HOLD signal. 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 opening doors.

The RCU devices integrate a function called AUTO-ZERO-SHORT. When

the device does not detect any weight changes of more than 20kg, for 2 minutes, it will eliminate any error that may appear below the value set as maximum compensation value. It also integrates the AUTO-ZERO-LONG function which after a 30 minutes pause, can make corrections of any weight. AUTO-ZERO-SHORT AUTO-ZERO-LONG ON ON ON OFF OFF ON OFF OFF If the maximum compensation value is set to 00000, the AUTO-ZERO-SHORT function will be disabled.

RCU devices integrate a function called AUTO-ZERO, which is activated after selecting a compensation type ⌧ and set a maximum compensation value ⌧ . This function is designed to automatically eliminate the small possible error that may appear below the marking as the maximum compensation value. The AUTO-ZERO function will be applied when the equipment 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.

4.6 CanOpen submenu

Some of the RCU models integrate CanOpen. In this submenu you will find some important parameters that can be configured such as the transmission speed of the equipment.
