USER MANUAL PLE-30
DIRECT CONTROLLED HOIST
DO’S AND DON’TS
Do’s
• Use the controller within the technical scope of the FEM class of
the Prolyft hoist. Longer operating time could severely damage
controller and hoist.
• Mount the controller in a protective casing
• Handle the controller only by the grips of the case
• Store the controller in its normal operating position away from
aggressive atmospheres (dust, humidity…).
• Make sure that the controller is always clean and protected from
corrosion.
• Only a competent person may install and operate the controller
• Make sure that connecting cables are in good condition and
connectors are fitted properly.
• Make sure that connecting cables are always symmetrical fitted.
• If the hoist direction is different from the Up /down indicators on
the controller, check intermediary cabling and change phases
by means of phase reverse facility in the CEE plug at the main
power cord
• Use only original parts in case of repair or replacements.
• During operation of the control, always remain alert. In case of
emergency, press the emergency stop button, this will inactivate
all functions of the control.
• Before operation, check if the load is correctly fastened and at-
tached to the hook. Do make sure the hook latches, if used, are
closed and not supporting any part of the load.
• Make sure you have an unobstructed view on the full travel path
of the load.
• Make sure that the load is in the correct position before moving
it.
• Make sure that each hoist is an exact vertical position to the load
and that the load chain is unobstructed, before operating the
controller.
• If used out doors, use sufficient protection against bad weather
conditions.
• Use the material under normal working conditions (ambient
temperature, atmosphere….)
• Moving a single load or truss system requires experienced and
competent operators.
• All the necessary precautions should be taken to ensure a correct
distribution of the load and to avoid overloading of a single hoist
when multiple hoists are used on one grid. The hoists should be
checked individually before they will be moved.
• Notify the responsible and competent person after a dangerous
operation or if the hoist seems no to function properly.
• Clear the area from obstacles and people and switch working
lights on before operating the controls.
• No people are being allowed under the load.
Don’ts
• Never connect a Prolyft controller to a power source other than
specified on the unit.
• Never modify the controller unless the manufacturer has
authorised the modification.
• Never modify the values and adjustments of the safety
components outside the limits provided in the manual, or without
the approval of the manufacturer
• Never try to repair or intervene on the controller without the
authorisation of the manufacturer or a qualified electrician.
• No unqualified personnel should operate the controller
• Never connect more hoists then the available number of outlets
(channels) or number of selector switches available.
• Do not use additional splitters to connect more than one hoist
per channel.
• Avoid shocks or accidental collision with other objects.
• Never open the controller as long as the system is under power.
• Never block, or lock the RUN button in order to continue a
movement without manual interference.
• Do not operate the controller if your physical condition does not
allow it.
• Never use the controller if it is in bad condition.
• Never use suspected spare parts or parts whose origin is not
known.
• Do not subject the controller to brutal shocks.
• Never distract the operator’s attention while he is operating the
system.
• Do not use the controller for a purpose or in an area for which it
is not intended.
• Do not expose the controller to an aggressive atmosphere
(temperature, acidity…)
• Do not use the safety components as operation components
(emergency button, main fuse switch. etc…)
• Do not use the controls needlessly (avoid inching – stop-start
operation of the buttons). This can cause overheating and even
damage to the hoist.
• Do not change the operating direction whilst the RUN button is
pressed (hoist under power).
• If the hoist direction doesn’t match with the indications on the
controller, don’t change phases inside the controller but check
the interconnecting cables or the individual hoist, after having
disconnected all power cables.
• Never use hoists who are running in the opposite direction of the
selected direction.
• Do not connect the controller to an unknown power supply;
check if the power source matches the specifications of the
controller and the hoists. (under voltage or over voltage =/- 5%,
absence of phase etc….)
