8. ALARMS CONFIGURATION
The alarms values correspond to the load threshold at which each relay change its state.
The relays allows to be configured individually as make or break contact
Alarms are activated when their threshold is exceeded. The Unit OMEGANG has 4 different alarms:
AL-1 (Full Load, Relay #1):
Change of state when exceeding the load programmed in
AL-2 (Over Load, Relay #2):
Change of state when exceeding the load programmed in
AL-3 (Zero Load, Relay #3):
Change of state when falling below the load programmed in
Note: This alarm is active below Alarm3 Threshold.
AL-4 (Rope Tension Difference and Slack Rope Tension, Relay #4):
Change of state if any rope has a slack rope tension or if any rope deviates from the average of all
other ropes at least by the percentage programmed in .
The working procedure of the relays as a make or break contact can be changed for each alarm output
using the parameter. Valid values are (Close) for the operating mode MAKE and (Open)
for the operating mode BREAK.Close is a normally closed relay and OPEn is a normally open
relay. Alarm LEDs indicators will be activated when the display measured value overload corresponding

9. CHAIN COMPENSATION
9.1. New Chain Compensation
The New Generation of Load Weighing Devices has the newest Software for chain
compensation. It offers several options to improve the accuracy to compensate the weight of the chain.
In this Submenu, the user can choose between three options, no compensation, software
compensation and hardware compensation.
9.2. Submenu Chain
Submenu
Press
to enter Check value Enter to modify
Type: Type of chain compensation applied. User can choose
between hardware compensation, software compensation or
none compensation
Value: Max Chain value to compensate. At installation.
Valid Values : 0-600
C_Bot: Chain zero operation at the ground floor
C_Top: Chain load operation at the top floor
C_Har: Real chain load value compensated by hardware
measure in selected units
ChCEL: Nominal Chain load cell sensibility. This value is
calculated when C_Bot or C_top operation is done. User
shouldn´t modify this value. ( If this parameter is modified
the previous calibration settings will be overwritten)
C_Sof: Chain load value compensated by software
estimation in selected units
Time 1: Time to get hold weight before Hold is activated
Time 2: Time to get hold weight after Hold is deactivated

User manual OMEGA
/
NG

9.3. Chain Compensation Adjust
The NG Series has new advanced chain compensation. To use all the features of new
compensation is necessary to adjust some parameters in Menu.
There are two types of compensation.
Software chain compensation: When selected, the unit compensate the chain with hold signal
activations/ deactivations.
Hardware chain compensation: When selected, the unit compensate the chain with the on real
time weight of the chain. This can be done using the auxiliary Load Cell input for chain
compensation and adjusting the parameters for hardware compensation.
Note: To deactivate all chain compensations just set Type parameter to none.
Set Type to None value.
9.3.1. Software Compensation
This function allows compensate the difference of weight between floors produced by the
chain. The unit needs the HOLD signal to be active when the doors close to compensate the
weight during the elevator movement.
To configure the software compensation:

Set Type to SoFT value.

Set the estimated weight of the chain. This parameter will be the maximum value
compensated by software compensation

In this parameter you can check the value the OMEGANG is compensating by software each
time the HOLD signal is deactivated
When using software compensation, Auto_Zero compensation will be activated automatically.
9.3.2. Hardware Compensation
In some installations ( the largest ones), software chain compensations doesn`t work
perfect due to different friction in the rails between floors, weight changes during long
elevator travels, or just any auto_zero is done cause elevator never stops.
These problems can be solved with Hardware compensation.
It is mandatory to plug an auxiliary Sensor (Load Cell for chain compensation)
when hardware compensation is selected. Otherwise Err11 will flash in the display.
Auto_Zero compensation will be also deactivated automatically
A system Configuration (Point 7) must be done previous to set the Hardware compensation
parameters.


Set Type to Hard value

Take the elevator to the ground floor and set C_Bot To Yes. A Countdown will
start.

Take the elevator to the Top floor and set C_TOP To Yes. A Countdown will start

In this parameter you can check the value the OMEGANG is compensating by hardware
with the chain load cell
9.3.3. Auto-Zeroing Compensation
The Auto_Zero compensation is designed to automatically remove small measurement error
lower than parameter
The Auto-Zero function will happen whenever the OMEGANG 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 OMEGANG applies 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 measure in
the display will be the same. To eliminate the Auto_Zero compensation, a Zero operation should be
done.

10. ADDITIONAL FUNCTIONS
10.1. Hold function
During the elevator travel, the measured loads can heavily fluctuate due to friction in the rails,
loads movements, etc. When a voltage in the range 24-230V (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.
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.
To improve the hold of a stable measure two parameters have been added at CHAIN menu
and .
As some installations sets the HOLD input at the same time it closes the doors, sometimes the
last measure obtained is not as stable as desire. The same issue can happen when removing the HOLD
input and the doors Open.
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:
If hold signal is activated, then, the OMEGANG will take as a valid measure the last stable weight
value that was stored 1 second before hold was activated. Then 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.
10.2. Analog output
(Optional)
This unit is provided with two analog outputs (Voltage and current output). Both Outputs are
active and operative at same time.
This function reflects the sensors signal over the range between ZERO and the value sets for
ALARM1 (full load):
Output Range
0-10 volts
( 0-5 Optional )
When weight ≤0kg
(empty elevator) 0 V
When weight ≥ALARM1
(elevator at full load)
10 V
( 5V Optional )
4-20 mA
When weight ≤0kg
(empty elevator) 4 mA
When weight ≥ALARM1
(elevator at full load) 20 mA

Example: Once the system is completely configured, if ALARM1 is set to 400 kg and if unit measures
200kg then;
0-10V Output will be 5V.
4-20mA output will be 12mA.
10.3. Cabin Display
(Optional)
It provides two types of output depending on the CDISP parameter:
LED Indicator: Under overload it will be an intermittent
voltage of 5V (max. 75mA) with the polarity shown in the

15. WIRE ROPE TENSION ADJUSTMENT
This section explains how to check the tension of all wire ropes of the installation. All ropes
should carry the same tension. Equally tensioned ropes improve ride quality and extend life of ropes and
sheaves.
Nowadays most elevator systems have multiple wire ropes attached to the cabin and
counterweight. This ropes normally run over a traction sheave or pulley just to move the cabin up and
down the hoistway.
When some ropes have more tension than other, the ropes with lower tension will slide over the
pulley and can produce a crown groove wear at the sheave. It is possible to detect this wear by rope
slapping, vibrations on the cables, or metal dust on the pulley.
Normally, the system works better if all the ropes have similar tension (about ± 5%) of the
nominal load of the installation.
Although some installers manage to adjust the rope tension manually just touching the ropes or
Just tuning the installation plucking each rope as a harp string, the best way to do this operation is
measuring the load on all the ropes and displaying it in real time.
Usually Load weighing devices manufactures have dedicated and expensive tools to do this
operations.
But the OMEGANG,can be used not only as a good Load Weighing device but as an additional
low cost rope tension balancing tool also.
And as the unit will be installed for life you will have a permanent tool to adjust wire rope tension
and detect slack ropes at the installation in real time.
15.1 Wire Rope Tension checking Tool
The only tool needed to adjust the wire rope tension is the WRCTNG dongle and a Smartphone a
tablet or a laptop. Then from the rope tension screen you will visualize the load of each rope in real time
Now it is possible to adjust the tension of each rope to make then equal.
