Safety- your responsibilities
In normal operation, it is essential that the scale cover, protective covers or panels are in place.
The conveyors should be fitted and in their correct place for the machine to operate.
Always stop the conveyors and disconnect the mains electrical and air supplies when making adjustments,
cleaning and setting the machine.
Ensure all stray objects are removed and the conveyors are clear before restarting the machine.
Ensure that the machine is switched off and disconnected from the electrical and air supplies before
removing any cover or panel.
The warning label shown below will be visible on covers that can be removed to access live parts.
Only qualified service engineers should access these parts
Electrical safety
This machine is fully earthed to current standards and fitted with a three-conductor power lead.
It is essential that the power lead earth conductor be connected to a good and proper earth point, which is
also used for adjacent and associated equipment.
The machine is protected by fuses in the live/phase power line. In countries where the machines power
plug can be inserted in the power socket in two orientations, great care must be taken to ensure that the
live/phase pin of the plug is inserted in the live/phase receptacle of the socket. In the event of any fuse
going open circuit, the cause should be rectified and the fuse replaced with one of the correct specification.
If a fuse is replaced by one not conforming to the specification, the result could be damage to the machine
or an electric shock to any person in contact with it.
The primary fuse can be found inside the electrical cabinet (lower left position). Ensure mains power is
isolated from the machine and using a small flat blade screw driver unclip the fuse holder complete with
fuse
For service engineers only
If working on live equipment, safety
glasses should be worn

HI, MI, WI 700 service manual - 1 - Installation
1-7 Issue 9 04/2020
Mechanical safety
The machine must be operated only when placed on a flat, level and solid floor. Adjust the feet so that the
machine is level and ensure that the locknut of each foot is fully tightened. Failure to comply with these
points may result in the machine falling over onto an operator.
All guards, covers and panels supplied with the machine must be fitted/closed whenever the machine is in
use.
Improper use
The machine has been designed to convey, weigh and label packs, which are within the size and weight
limits detailed in the Specifications. Using the machine for any other purpose may cause damage to the
machine and/or injury to the user or other persons.
Safety–Emergency stop
The HI-700, MI-700 & WI-700 are fitted with an emergency stop switch located on the control box. When
the machine is running, a sharp push on the button head will stop the conveyors.
NOTE: only the conveyor belts will be stopped in this operation, the console software will remain on and
accumulated information will not be lost.
When the emergency has been rectified, and the machine is safe to switch on again, the emergency stop
button can be released to the "running" position by pulling it back out again.
The conveyors can then be restarted by pressing the green "START" button.

HI, MI, WI 700 service manual - 1 - Installation
1-8 Issue 9 04/2020
Moving the machine
When moving the machine the labeller should be supported to stop lateral movement.
If moving only a short distance over a smooth surface the machine can be moved carefully to its new
location with the aid of the lifting angles, supplied with the machine.
Fit the lifting angles onto the machine feet / frame, tighten the locking nut on each foot stem and transport
using a hand pallet truck or powered fork lift truck
If moving a long distance, it should be placed on a strong pallet, use lifting angles as described above and
clamped down to stop it moving on the pallet. Protect the load cell by placing the transit screw and discs in
position and support the labeller.
Protect the machine from environmental conditions and then move on the pallet by appropriate transport.
CAUTION
The machine is heavy and has a high centre of gravity, which can affect its stability when it is being
moved. Great care must be taken when moving the machine to ensure that it does not topple over.
This is especially important if moving the machine on a floor with a gradient
Lifting angles
To fit the lifting angles, loosen the foot stem locking nuts and slide the lifting angles onto the foot stems of
the machine, between the frame end and locking nut.
With lifting angle in place, retighten the locking nuts to secure lifting angle in place

Installation requirements
Site requirements
This machine is designed to work within the normal environments associated with the food industry, i.e.
humidity – non condensing environment and temperature between 0°C and +30°C. Weighing and labelling
equipment is however sensitive to misuse and due care and attention should be given to the operating
environment.
Environment
Excessive water and foreign matter must not be allowed to build up on flat surfaces.
The operating temperature and humidity must be within the machine specification.
Aggressive chemicals may attack and degrade conveyor belts and the internal workings of the machine.
Location
The machine should be operated on a flat level surface. On uneven floors due care must be taken to level
the machine. Sloping floors should be avoided as the machine may slip or even fall over.
The machine should be positioned on a solid (vibration free) flat floor. The outfeed of the machine must
allow the packs to leave the machine smoothly and continuously at all times. It is very important that the
transfer of packs from the outfeed conveyor is not blocked as this may cause damage to the machine.
Electrical supply
The machine requires an electrical supply of either 220-240 V AC at 50 Hz or 105-115 V AC at 60 Hz,
depending on machine version and country.
Fusing
The machine is fused in the live/phase line, great care should be taken to ensure that the live/phase
connection of the machine is mated to the live/phase connection of the supply.
Interference
The supply must be free from large spikes, dropouts and other types of line borne interference.
If the supply is subject to interference additional equipment may be needed to bring the supply condition up
to an acceptable level.
Connection
The electrical supply should conform to relevant national or international standards with regard to safety, in
particular electrical earth requirements.
The supply connection should ensure accidental disconnection is unlikely.
Warning
If the machine is connected to an incorrect voltage supply, or if the phase and neutral supply lines
are crossed, there may be serious damage to the machine and serious injury to the user or other
persons.
Air supply
This machine is fitted with a label printer, which requires a supply of clean compressed air. The supply must
be free of oil or water, either as a mist or vapour. The air requirement is a pressure range of 4 - 6 bar at 50
to 300 ltrs/min. The Air pressure filter/regulator is located on the outfeed/labeller frame.
Accreditation
Weighing and price labelling machinery is usually subject to checking or monitoring according to a national,
or E.C. authority. A seal or stamp may need to be applied to the machine before use.
