Chapter V Extended Function
Henghui Intelligence Aided Lifting Equipment may achieve the following extended functions
through the extended port IO:
Inching function, mode switch, double limit function, double suspension function,
automatic homing function, anti-drop function, stacking function
The extended function needs to configure the IO port that the expansion port needs, and input
(output) the required signal through the configured IO port in order to use normally. The extended
port provided by Henghui Intelligent Lifting Equipment includes the following types: Main
machine extended port, handle extended port and external extended module. The user may select
the suitable extended port according to actual conditions.
The extended port IO required for the extended function can be configured by the user. All
extended ports IO ports of Henghui Intelligent Lifting Equipment have the respective and sole
number, easy to be set by user.
(No. 0 is invalid for setting IO)
5.1 Inching function
By controlling the IO signal of the extension interface, the equipment can run at four constant
speeds: slow gear upwards, slow gear downwards, fast gear upwards and fast gear downwards. In
the “lifting speed adjustment”
→
“setting of inching speed”, the speed of the fast/slow gear can
be set by “inching fast gear” and “inching slow gear”.
5.1.1 Usage mode
The control signals of the fast/slow gears can be input through interfaces on the host
extension board, handle extension board, or expansion board. In the "Expansion Function Setting"
→
"Expansion Interface Setting", the corresponding IO numbers for "Slow Gear Upwards", "Slow
Gear Downwards", "Fast Gear Upwards" and "Fast Gear Downwards" can be set.
For example:
Set the 9
th
, 10
th
, 11
th
and 12
th
pins on the extension interface of the coaxial
handle as the inputs of "Slow Gear Upwards", "Slow Gear Downwards", "Fast Gear Upwards" and
"Fast Gear Downwards". Connect the 9
th
pin and the 6
th
pin on the handle extension interface to
the normally open contacts of Switch K1 (self-recovery), and then set the IO number to 12 in the
"Slow Gear Upwards" menu. Connect the 10
th
pin and the 6
th
pin to the normally open contacts of
Switch K2 (self-recovery), and then set the IO number to 13 in the "Slow Gear Downwards" menu.
Connect the 11
th
pin and the 6
th
pin to the normally open contacts of Switch K3 (self-recovery),
then set the IO number to 14 in the "Fast Gear Upwards" menu. Connect the 12
th
pin and the 6
th
pin to the normally open contacts of Switch K4 (self-recovery), and then set the IO number to 15
in the "Fast Gear Downwards" menu. When the contacts of Switch K1 are connected, the
