seconds to enter the double suspended state.

Signal selection
The two suspended states in the double suspension function are controlled by the configured
signal. Henghui Intelligent Lifting Equipment provides the following three switching signals:
Single signal, dual signal and fixture signal.
Single signal and dual signal are generally triggered manually by the operator to switch
between two suspended states. The fixture signal then switches the suspended state by the
clamping and releasing feedback sensor (switch) mounted on the fixture. Automatic switching of
double suspended state can be achieved if the fixture signal is used.

Single (Dual) signal setting
①
In the “Extended Function Setting”
→
“Double Suspension Setting”
→
“Signal
Selection”, set the switching signal type, and select “Single Signal” or “Dual Signal” for
manual switching as required.
②
According to the selected switching signal type and the actual wiring in the host
expansion, handle extension or expansion board input port. If using “single signal”
switching, you need to set the corresponding IO number in “Extended Function
Settings”, “Extended Port Settings”, and “Switching Double Suspension 1”; if using
“Dual Signal” switching, you need to set “Switching Double Suspension 1” and
“Switching Double Suspension 2” IO number, simultaneously.
For example:
Take the Pin 11 and Pin 12 of the coaxial handle extended port as the
double suspension startup signal input end. Connect the Pin 11 and Pin 6 of the handle
extended port to the normally open contacts of the switch K1 (self-recovery), and then
set the IO number 12 in “switching double suspension 1”. Connect the Pin 12 and Pin 6
of the handle extended port to the normally open contacts of the switch K2
(self-recovery), and then set the IO number 13 in “switching double suspension 2”.
③
When the set signal selects “single signal”, it is necessary to press and hold (about 2s)
the switch K1 when entering double suspended state. When switching the double
suspended state, only the switch K1 needs to be triggered; if the set signal selects “dual
signal”, press the switch K1 when entering the double suspension mode, and then press
and hold (about 2s) the switch K2. When switching the double suspended state, you
need to press the switch K1 first, and then trigger the switch K2 to switch normally.
“Dual signal” can increase the security of the operation.
5.4.3.2
Fixture signal setting
When the double suspension is switched using the fixture signal, if in the manual mode, the
system must set three (3) IO input signals, which are: switching double suspension 1, clamping
