Intelligence Aided Lifting Equipment

The handle always
shows “Emergency
Stop Mode”
1. Caused by the
emergency stop switch
itself;
2. The emergency stop
signal
cable
is
blocked;
3. There is a problem
with the handle or the
main circuit board.
Make sure the emergency stop button pops up
normally.
Check whether the emergency stop signal cable
of the signal cables is normally turned on: for
indefinitely variable speeds handles, coaxial
handles, all – touch handles and remote
installation sliding handles, please check the Pin
5 of handle end connector and the Pin 5 of host
end. [Chapter 2.5]
Check
whether
the
internal
cable
WI-830000014 of the host is normally turned
on.
Check the handle slipping rings and internal
connecting cables.
Replace the main circuit board.
The equipment is
always in “Lock
Mode”
1. For sliding handles
and coaxial pressure
handles: the infrared
sensor cannot sense
properly;
2.
For
indefinitely
variable
speeds
handles and all – touch
handles: the sensor or
the handle board is
abnormal.
For sliding handles and coaxial pressure
handles: check that the infrared sensor is
normally on/off in the “Service” > “Hardware
Diagnostics” > “Handle Holder Signal” menu.
If the infrared sensor is normally on: clean the
infrared sensor probe and the perimeter to
ensure that there is no object interference under
the handle. [Chapter 4.1.2]
If the infrared sensor is normally off: check if
the infrared sensor connector inside the handle
is loose and replace the infrared sensor or
handle board.
For indefinitely variable speeds handles: press
the “UP” and “Down” button in the “Service” >
“Handle Holder Calibration”, and the value will
change from the correct value (less than ±150)
to the wrong value (around ±1800).
If the value does not change: check if the
magnet in the magnetic cylinder is off, and
replace the sensor board and the handle board.
