4. Install Method of Sensor and Controller:
①Adjust traction ropes so that the pull of each rope keeps coincident.
②The sensor is installed at the place of the elevator- car-side traction rope shackle according to Fig. [2] and refer to it
for more details.
③
Control Section should be installed in the control cabinet placed in machineroom
，
being 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.
④It 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.
⑤
Connect the sensor wiring terminal to PG terminal of the control, simultaneously, connect power line to PV
according to system requirement. Pay attention to the voltage level.
⑥When 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.

no load point drifting. It is recommended for the user to allow or forbid this function according the concrete conditions.
③ Even if No load auto zeroing operation enabled，in the course of elevator periodical maintenance，autotuning operation
of this system should be redone without exception.

1. The working stability of the weighing device is poor, which is mainly manifested in the static condition of the fixed load
elevator, and the output fluctuation is large.
Please check whether the PV power supply meets the requirements of the weighing device.
2. After long-term operation, the no-load zero point of the weighing device has a large deviation?
It may be caused by part of the reasons mentioned in "V and 4". Please set the self-learning mode of the weighing device to
recalibrate, or start the parameter "PE≠0" to realize the no-load automatic zero clearing function of the weighing device.
3. Poor consistency of floor compensation?
Change the lower value of P4.
4. The same load up and down running on the same layer, weighing results are different?
① The drawstring is not even, please adjust; (2) The elevator guide boots are too tight, and the operation friction is large. It
is suggested to adjust or correct the relevant mechanical part to make it run flexibly, and then re-learn the operation of the
weighing device.
5. Weighing device output signal does not change linearly with the load?
Maybe the weighing device sensor is damaged.
6. How to view the current car payload?
Press the [▲] button during the normal operation of the weighing device. At this time, the weighing device displays 〖HJ〗
→〖**〗→〖**〗O; For example, the display - [HJ] → [09] → [50] O - indicates that the current payload of the 1000kg
car is 950kg;
If the elevator payload is not 1000 kg, it can be determined by modifying "P1" parameter after the learning operation of the
weighing device is completed; The display data may fluctuate in a small range due to various influences of the external
environment;

7. When the elevator is stationary, the weighing signal is normal, but there are abnormal phenomena in the process of
opening and closing the door?
The elevator door dynamic weighing device produces the relative weight deviation of the car. The output signal of the door
opening and closing relay plus the door lock signal can be used to participate in the PM.1~2 locking control of the weighing
device.
8. During the operation of the weighing device, abnormal analog output or repeated reset or abnormal coordination with the
governor occurs?
It may be caused by crosstalk of the power supply of the weighing device. Another set of power supplies should be used to
power the weighing device, or AC/DC 24V/300mA external power supply should be used to power the weighing device.
11. How to re-do the "self-learning" operation of the weighing device ?
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
？
After system displaying 〖Lo〗，modify parameter“P1=02”.Do no load autotuning operation as described in chapter 6. In the
period of displaying〖PH〗，load elevator car with a weight equal to 20% of rated load to do rated load autotuning operation.
When operation is finished,〖L1〗is displayed.

With the development of the elevator technology, the elevator load weighing has great effect on the the performance of the
elevator. Higher accuracy,more reliable and more functional elevator load weighing is desperately needed. In the era of the
high development of the sensor and the microcomputer, adopting the high accuracy”disc” load sensor to detect the electric
signal to the change of the car load, meanwhile using the single chip microcomputer to have a scentific processing, to
achieve the working function of the elevator car effective load weighing.
14.Main Characteristic：
① Adopting direct pressure type ”disc” load weighing device, there is no need to change the pull rod of the tractive rope.
②Weighing range is wide (effective load of 500Kg ～ 5500 Kg) ， high-accuracy position ， intelligent temperature
compensation.
③Inner core consists of highly accurate load sensor and high performance single-chip micro-computer. All
operation parameters can be set on field.
④System may do scientific calculation according to mathematical equations with the function of no-load auto
zeroing，automatically modifying measuring error.
⑤With the function of fuzzy compensation to improve the high requirements the elevator to the load signal.
⑥With the ability of load setting under auto tare or the working function of 20% or 100% autotuning rated load, it is
very convenience to the customers.
⑦Adjusting the autotuning at the spot, and it very convenient to do the adjustment.
⑧With the ability to modify the working parameters automatically and fuzzy compensation.
⑨The whole shoot starts from users’ point of view，easy installation and adjustment，decreasing users’
additional cost in use，high ratio of performance to price.
