Whether up or down landing signals or leveling signal is normally wiring
,
Setting of parameter P5 is
reasonable?
⑸Traveling Up and down with the same load and stopping at the same floor, but the weighing result is different?
1
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.
⑹System output signal doesn’t change linearly along with load?
Maybe system sensor is damaged.

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.
⑻When elevator is motionless, weighing signal is normal. But in the course of door opening, it is abnormal?
⑼
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 1:Simultaneously press【▲】and 【▼】on system control panel to power on. This moment,
system aglimmer displays〖PP〗and 〖P-〗.Keep 10 seconds,system will display〖Pn〗.On
that occasion,all operation parameters reset to default settings.
