How to do

10.Brief Analysis of Other Conditions：
⑴ Bad system Operation Stability with the main indication of large output fluctuation in the condition of fixed
load and elevator motionless？
Check if PV power supply source fulfils system requirements?
⑵ After long-term of operation, system no load zeroing point appears larger deviation？
May be caused by the reason described in section 4 , chapter 5. Set system Autotuning mode to calibrate again，or
startup parameter“PE≠0” to realize the function of system no load auto zeroing.
Poor Landing Compensation consistency？
Modify lower bits of Parameter“P4”.
⑷ 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.
⑸ System output signal doesn’t change linearly along with load？
EWD-RL-SJ3 Intelligent elevator weighing device technical document user manual[V2.2]
Page 12 total 26
Maybe system sensor damaged.
⑹ How to descry present effective load of elevator car？
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.
If elevator effective load is not 1000 Kg，it may be decided after system autotuning operation is finished by
modifying parameter“P1”.
Because of various impacts from outer environment，displayed data may fluctuate in a small scope.
⑺ When elevator is motionless, weighing signal is normal. But in the course of door opening, it is abnormal？
Elevator door operation system causes relative car weight offset. It may be controlled by adopting door
opening/closing relay output signals+ door lock signal jointly participating system PC.3～4 locking control.
⑻During 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
system，or equip another AC/DC 24V/300mA exterior power source to supply power.
11. How to do Re-Autotune operation for system?
Method 1：Simultaneously press【▲】and【▼】 on system control panel to power on. This moment, system
aglimmer displays〖PP〗.Keep 15 seconds，system will display〖Pn〗.On that occasion，all operation
parameters reset to default settings.
Method 2：Modifying 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 6.
12. How to adopt 20% rated load for rated load autotune？
EWD-RL-SJ3 Intelligent elevator weighing device technical document user manual[V2.2]
Page 13 total 26
Modify parameter "P1=02" after the weighing device displays 〖Lo〗. The no-load self-learning of the weighing
device is completed in accordance with the "Five" chapter. During the display 〖PH〗, the weight equivalent to 20% of
the rated load of the elevator should be added to the car for the load self-learning operation. After the operation is
completed, the display 〖J1〗 will be displayed.

13.Working Principle of“EWD-RL-SJ3”Elevator Weighing Device
With the constantly development of elevator technology, the impact of elevator weighing devices 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. Nowadays, the progress of sensor technology and
microcomputer is ceaseless. Inspecting electric signals producing by elevator car load changing with high accurate
“Disc” type loading sensor, meanwhile, performing scientific calculation and procession with single-chip
microprocessor, the aim of weighing elevator car effective load is fulfilled.
14. Main Characteristic：
①Selecting directly-compressing“Disc”type load sensor，it is unnecessary to change the pull rod of traction rope
shackle.
②Weighing range is wide (effective load of 300Kg～5000 Kg)，high-accuracy position，intelligent temperature
compensation.
③ Inner core consists of highly accurate load sensor and high performance single-chip micro-computer. All
operation parameters can be set on field.
④ System may do scientific calculation according to mathematical equations with the function of no-load auto
zeroing，automatically modifying measuring error.
⑤The capability of fuzzy compensation improves the requirement of elevator for high accuracy weighing signals.
