2.Installing Method and Working Principle of “EWD-RLG-SJ3”
With the constantly development of elevator
technology, the impact of elevator weighing device
on elevator performance can not be neglected. The
requirement of elevator for weighing devices with
high accuracy, high reliability and multi functions
becomes extremely urgent. Presently, the progress of
sensor technology and microcomputer is ceaseless.
With the adoption of highly accurate
intelligent ”tension” or ”load” and “stress” sensors,
the electric signal produced by elevator car load changing is tested and inspected. System sensor
installed at the traction rope hitch: Type“EWD-RLG-SJ3”There is an 8~10-meter-long signal
transmitting cable with the sensor. And the single-chip built-in the controller may do scientific

Install Method of Sensor and Controller:
Adjust traction ropes so that the pull of each rope keeps coincident.
XCL-Y/8625: “Disc” type sensor is installed at the place of the elevator- car-side traction rope shackle
according to Fig. [3A.1] and Fig. [3A.2] with customer-made shackle clamp plate.
XCL-ZL/W: Character type tension sensor is installed at the place of the elevator- car-side traction
rope shackle according to Fig. [3B] and refer to it for more details.
XCL-T/A: Character type load sensor is installed at the place of the elevator- car-side traction rope
shackle according to Fig. [3D] with customer-made shackle clamp plate.
Control Section should be installed in the control cabinet placed in machineroombeing away from
equipments such as the transformer, speed regulator of elevator electric control system. Under any
condition, sensor and controller should be far away from heat source.
It would be better not to put the connecting cable between sensor and controller in the same wire duct
with dynamic power of 110V or 220V.
Connect the sensor wiring terminal to PS terminal of the control, simultaneously, connect power line to
PV according to system requirement. Pay attention to the voltage level.
When no error is inspected, power on the system and the corresponding operation patterns will be
displayed on the control.

System adjustment under other conditions
For following reasons, the parameters of this system need re-modifying in the way described above.
1) Elevator car decoration changing causes its dead weight change.
2) Larger unbalance appears among traction ropes.
3) Sensor of weighing device becomes flexible.
4) Overrunning at the top or at the bottom occurs.

reasonable?
Traveling Up and down with the same load and stopping at the same floor, but the weighing result is different?

Lift rope pull is not symmetrical
adjust please.
2
Elevator guide shoes are too tightened
running friction is large. It is recommended to adjust or modify relevant
mechanical part to make it move flexible
then operate the system to autotune again.
System output signal doesn’t change linearly along with load
Maybe system sensor is damaged.
How to descry present effective load of elevator car
1
In the period of system normal operation, press button
.This moment, system displays
HJ
**
**
.For example
displaying
HJ
09
50
indicates a car with rated load of 1000 Kg presently
bearing an effective load of 950Kg.
2
If elevator effective load is not 1000 Kg
it may be decided after system autotuning operation is finished by
modifying parameter“P1”.
3
Because of various impacts from outer environment
displayed data may fluctuate in a small scope.
When elevator is motionless, weighing signal is normal. But in the course of door opening, it is abnormal
During system operation, analog output is abnormal, repeatedly resetting or abnormal coordination with speed regulator
May be caused by crossing and interfering system power source. Select another set of power source to supply
power to system
or equip AC/DC 24V/300mA exterior power source to supply power.
13.How to Repeat doing Autotune operation for system?
Method 1Simultaneously press【▲】and 【▼】on system control panel to power on. This moment,
system aglimmer displaysPPand P-.Keep 10 secondssystem will displayPn.On
that occasionall operation parameters reset to default settings.

Method 2Modifying parameter P0=0A will reset system immediately to default status. But for
users with specified code, it is necessary to modify parameter P0 as appointed code. Detailed operation is
described in chapter 8.
14.How to adopt 20% rated load for rated load autotune
After system displayingLomodify parameter“P1=02”.Do no load autotuning operation as described
in chapter 7. In the period of displayingPHload elevator car with a weight equal to 20% of rated load
to do rated load autotuning operation. When operation is finished,L1is displayed.
