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 OMEGA
ng
has 5 different alarms:
AL1-F (Full Load Relay #1):
Change of state when exceeding the load programmed in
AL2-O (Over Load Relay #2):
Change of state when exceeding the load programmed in
AL3-E (Empty Load Relay #3):
Change of state when falling below the load programmed in
Note: This alarm is active below Alarm3 Threshold.
AL4-d (Rope Tension Difference Relay #4):
Change of state if any ope deviates f om the ave age of all othe opes at least by the pe centage
programmed in .
AL5-S ( Slack Rope Relay #4):
Change of state if any rope has a slack rope tension ( A value below alarm level threshold)
When Slack Rope Alarm is activated the word “Slack” will flash on the display.
The working procedure of the relays as a make or break contact can be changed for each alarm output
using the parameter. Valid values a e (Close) fo the ope ating mode MAKE and (Open)
fo the ope ating mode BREAK. Close is a no mally closed elay and OPEn is a no mally open
elay. Alarm LEDs indicators will be activated when the display measured value overload corresponding

ChCEL: Nominal Chain load cell sensibility. This value is
calculated when C_Bot or C_top operation is done. Use
shouldn´t modify this value. ( If this parameter is modified the
previous calibration settings will be overwritten) ( only applies to
Hardware compensation) .
C_Sof: Chain load value compensated by software estimation in
selected units
Time 1:
Starting Time to hold the weight before Hold input is
activated. It is an optional correction on installations where the Hold
Input is activated too fast. (Units are tenths of seconds). (Default
Recommended Value: 2 (0.2secs)).
(only applies when hold input is connected)
.
Time 2:
Delay time to release hold weight after Hold input is
deactivated. It is an optional correction on installations where the Hold
Input is deactivated too fast. (Units are tenths of seconds).
(Default
Recommended Value: 4 (0.4secs)).

T1 and T2 options are only shown if is set to SOFT compensation. See Section
10 Hold Function to adjust these parameters.
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.
 oftware chain compensation: When selected the unit compensates the chain with hold signal
activations/ deactivations.
Note: and parameters must be set to use the Software Chain compensation.
 Hardware chain compensation: When selected the unit compensates 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 value.
9.3.1. Softwa e Compensation
This function compensates the weighting difference between floors produced by the extra
weight of the chain and the travelling cables. The unit needs the HOLD signal to be active when
the doors closed 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 OMEGA
ng
is compensating by software each
time the HOLD signal is deactivated
When using software compensation Auto_Zero compensation will be activated automatically.

OMEGA
ng

9.3.2. Ha dwa e Compensation
In some installations with many landings software chain compensations does not work
well due to friction in the rails between floors weight changes during long elevator travels or
auto_zero does not occur because elevator never stops.
These problems can be solved with Hardware compensation.
It is mandatory to plug an auxiliary Sensor when hardware compensation is selected.
A dedicated Load Cell for chain compensation is needed. Otherwise Err11 will flash in the
display.
A system Configuration (Section 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 OMEGA
ng
is compensating by hardware with
the chain load cell
10. Auto-Ze oing Compensation
The Auto_Zero compensation is designed to automatically remove small measurement errors
lower than parameter
The Auto-Zero function will happen whenever the OMEGA
ng
detects a total unload of the
elevator and measures a static offset of ± for a period of at least 60 seconds. During this
time the measured load must not change by more than ±20kg.
To eliminate the Auto_Zero compensation a Zero operation should be done.
If is set to “00000” Auto_Zero compensation will
be automatically disabled.

11. ADDITIONAL FUNCTIONS
11.1. Hold function
During the elevator travel the measured loads can greatly fluctuate due to friction in the rails
cab and load movements etc. The Hold Input prevents the control from measuring the load
while the elevator is travelling 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 measurement 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.
The OMEGA
ng
unit has an 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 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: For example; With T_1 set at 10 and T2 set at 15:
When the hold signal is activated then the OMEGA
ng
will take as a valid load measurement the
value that was stored 1 second before HOLD signal was activated. Then when HOLD input is released
the first stable load 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.
11.2. Cabin Display (Optional)
It provides two types of output depending on the Cabin Display (CDISP)
parameter:

OMEGA

connection with polarity) (Requires an external MB-D unit).
12. ANALOG OUTPUT
The unit is provided with two analog outputs (Voltage and current output). Both Outputs are
active and operative at same time.
Analog_High: Set the Load value desired (kg or Lb) To
deliver the maximum analog output ( 10v or 20 ma)

17. 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 OMEGA
ng
, 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.
17.1 Wi e Rope Tension checking Tool
The only tool needed to adjust the wire rope tension is the WRCT
NG
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.
