Put down the lift object and ensure that all GripOk signals are correct. The hoist can now be

operated as normal.

Check grip- release interlocking according to paragraph 2.2.

3. Check MaxPressure by adding weight to the hoist when the lifting object 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 MaxPressure.

4. Run the hoist as far up as possible. If you do not reached the height you are supposed to, there may be some

mechanical interference or someone has changed a parameter i the controller card – see Troubleshooting.

THE HOISTS 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 table, the hoist will have support for a while but

eventually the gripper tool will fall off the edge and will because of that pick up speed sideways as well – make

sure the surface is firm and that there is no obstacles.

2. The gripper tool uses vacuum to hold the load, these vacuum tools can be 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

the grip-valve in an attempt to secure the lift object NOTE. There is no guarantee that the grip is correct at this time,

the lift object can have slipped out of its proper position – be aware of any abnormality 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 (

If the air pressure in the system is lower than the set value for P03 the lift is ready to use as normal.

OPERATING INSTRUCTION

All maneuvers must be performed carefully. Make sure that no-one is under suspended load.

Switch on the equipment, the circuit breaker can be placed on or nearby the equipment, the electrical connection can

also be a simple wall plug. As soon as the equipment is powered the hoist is active, this is indicated by a bar 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 bars indicate the signal from the handle. Bar upside – up signal, bar in the middle –

handle I neutral position (no pushing or pulling), bar downside – down signal.

If the hoist is equipped with a gripper tool that has interlock functions, these interlock functions must be checked

before use – see Safety control of the equipment.

The maneuver handle responds to the hands push/pull movement and the handle must be moved gentle, small

movements results in low speed of the hoist and large movements' results in high speed. The pictures below show 2

ways of how to hold the handle.
