5.2 ) Load Point adjustment: With This function the Unit will be adjusted with the best accuracy.
Put a well known weight inside the cabin. It Is recommendable to set up to 60% of elevator duty load.
To make the Load point adjustment:
5.3 ) Cell Value: Cell value is automatically calculated after a Load Point adjustment, so users
don´t need to adjust it. This parameter stores the Sensor Sensibility. If Cell Value is changed by
the user, the previous calibrating process will be overwritten. Contact your local distributor If you
need to modify this parameter.
7. ALARMS CONFIGURATION
The alarms values correspond to the load thresholds or limit at which each relay change its state.
The relays allow to be configured individually as make (Normally Close) or break contact (Normally Open)
Alarms are activated when their thresholds are exceeded. The Unit RCU_2Ra has to 2 different alarms:
AL1-F (Full Load, Relay #1):

Time 1: Starting Time to hold the weight before Hold input is activated.
It is and optional correction on installations where the Hold Input
is activated too fast. (Units are Decs of seconds). (Default
Recommended Value: 2 (0.2secs)).
This function compensates the weighting difference between floors produced by the extra weight of the chain
and travelling cables. The unit needs the HOLD signal to be active when the doors closed to compensate the weight
during the elevator movement.
Set the estimated weight of the chain. This parameter will be the maximum value compensated by
software compensation. (200kg is the recommended value )
In this parameter you can check the value that the RCU is compensating by software each time
the HOLD signal is deactivated.

User manual RCU_210
9. HOLD FUNCTION
During the elevator travel, the measured loads can heavily fluctuate due to friction in the rails, loads
movements, etc. The Hold Input inhibits the measure while the elevator is travelling, so this ensures that the
movement of the cabin will not affect the weighing process and therefore, no alarms or relay will be activated during
elevator travel.
How Hold Input Function works:
When a voltage in the range 24-125V (DC or AC) is applied in this input, the unit holds the last stable
measure of weight acquired.
The voltage must be applied when the doors close and it must be removed as the doors open.
The RCU_210 has a internal register that stores all previous weighting measures of the last 3 seconds.
As some installations sets the HOLD input at the same time the doors closes, it may happen that the last
measure obtained could not be as stable as desired. The same issue might happen when removing the HOLD input
as the doors Open.
To improve the hold of a stable measure, two parameters have been added at menu;
and .
For example:
Time in tenth of seconds to take the measure before the hold Signal is active.
Time in tenth of seconds to update the measure after the hold Signal is released.
Note: With T_1 = 10 and T2 = 15:
In this case, if hold signal is activated, then, the RCU will take as a valid measure the last stable weighing
value that was stored 1 second before hold was activated. In the same way, when hold is released the first stable
value will be taken 1.5 seconds after the hold signal is deactivated.
This option offers great flexibility to resolve problems in some critical installations.
The Auto_Zero compensation is designed to automatically eliminate small measurement errors lower than
parameter of Submenu.
The Auto-Zero function will happen whenever the RCU measures a static offset of ± for a period of
at least 120 seconds. During this time the measured load must not change by more than 20kg. The RCU will apply an
internal compensation value equal to the inverse value of the currently measured offset.
The Auto_Zero compensation value is stored in internal memory. After power cycling the unit the measure in the
display should not change therefore. To eliminate the stored Auto_Zero compensation, a Zero operation should be
done.

Analog_High: Load Value for which the unit will deliver the
maximum analog output ( 10v )
Analog_Low: Load Value for which the unit will deliver the minimum

This function reflects the Display measure over the range between analog Low and analog High values
When hold (inhibit) input is activated the analog output will not change during elevator
travel, until hold input deactivation.
