2. Put down the lift o ject and ensure that all GripOk signals are correct. The hoist can now e
operated as normal.
3. Check grip- release interlocking according to paragraph 2.2.
3. Check Max ressure y adding weight to the hoist when the lifting o ject is hanging in the gripper tool, the hoist
will stop going further up when the air pressure in the hoist system is over the level Max ressure.
4. Run the hoist as far up as possi le. If you do not reached the height you are supposed to, there may e some
mechanical interference or someone has changed a parameter i the controller card – see Trou leshooting.
THE H OIS TS BOOT SEQUENCE
If the hoist system by any reason should get the power shut off or if the compressed air will disappear and there is load in
the gripper tool, something of the following will happen if the power/compressed air do not return.
1. Compressed air will slowly leak out from the hoist system and the gripper tool will descent to the nearest
surface, if the gripper tool lands on e.g. the edge of a ta le, the hoist will have support for a while ut
eventually the gripper tool will fall off the edge and will ecause of that pick up speed sideways as well – make
sure the surface is firm and that there is no o stacles.
2. The gripper tool uses vacuum to hold the load, these vacuum tools can e leaking slow to very fast depending
of vacuum tool – the load can fall out rather quick.
3. The gripper tool uses cylinders/other pneumatic and the compressed air will leak out slow.
When the hoist system is started, the system starts in 2 different ways, this depends if interlocking is used or not. If
parameter
P03 (ReleaseOk) is set to zero(0), then there is no interlocking and the system will start without diagnosing its
current state. If a value is set for parameter P03 and the air pressure
is higher than this value, the system will activate
the grip-valve in an attempt to secure the lift o ject NOTE. There is no guarantee that the grip is correct at this time,
the lift o ject can have slipped out of its proper position – e aware of any a normality when the system is started with
load in the gripper tool. The system align to its current state automatically i.e. it does not matter if you use grip/release
or hover/grip/release function (
P07 (ButtonFunction)) - the system will start with the grip phase.
If the air pressure in the system is lower than the set value for P03 the lift is ready to use as normal.
OPER A TIN G IN STR U CT ION
All maneuvers must e performed carefully. Make sure that no-one is under suspended load.
Switch on the equipment, the circuit reaker can e placed on or near y the equipment, the electrical connection can
also e a simple wall plug. As soon as the equipment is powered the hoist is active, this is indicated y a ar and digits
are lit (green) in the display on the hoist’s left side.
In normal mode the digits show how many lift cycles there are remaining to next
maintenance, the digits show how many cycles in percent of 250.000 cycles e.g. –22 means
that there are 22 percent of 250 000 lift cycles left (55000).
The ars indicate the signal from the handle. Bar upside – up signal, ar in the middle –
handle I neutral position (no pushing or pulling), ar downside – down signal.
If the hoist is equipped with a gripper tool that has interlock functions, these interlock functions must e checked
efore use – see Safety control of the equipment.
The maneuver handle responds to the hands push/pull movement and the handle must e moved gentle, small
movements results in low speed of the hoist and large movements’ results in high speed. The pictures elow show 2
ways of how to hold the handle.
