Rev.4 del 01/2011 O.M.A.C. s.r.l.
As an optional feature, the LDPU can come with the full fairing. Below there are the above mentioned safety systems.
1.7.1 Flexible transmission coupling protection
The fl exible transmission coupling is protected by a removable mechanical transmission device, made up of an even coverage, accurately shaped and
made of AISI 304 or aluminium, which protects the operators from contact with the rotating parts.
DANGER
It is absolutely forbidden to operate the LDPU if the safety devices have been removed.
1.7.2 Emergency stop
The emergency stop is a safety system made up of a red button, in the shape of a mushroom, on a yellow background and fi tted on the electric panel,
eventually supplied with the LDPU. These buttons, when present and pressed, block the work cycle of the LDPU, stopping every movement in a few
seconds: therefore they have no effect on stopping the work cycle of the plant the LDPU is connected to. Therefore, to stop the operation of the plant,
upstream and downstream from the pump, one must act on the plant emergency stop buttons.
DANGER
This emergency stop button IS NOT THE PLANT EMERGENCY STOP BUTTON.
To stop the operation of the plant, upstream and downstream from the pump, one must act on the plant emergency stop buttons.
The emergency stop button can only be used in situations of severe and immediate danger, which require the immediate stop of all parts. Once the button
has been pressed it will stay blocked until the operator performs its manual unblocking (by rotating it in the direction indicated by the arrow printed on the
control), thus maintaining the LDPU in a state of emergency.
DANGER
It is absolutely forbidden to operate the LDPU if the safety devices have been removed. Damaged safety devices must be replaced immediately. Never
neutralise the safety devices.
1.7.3 Seals protections
The seals protections, re. position 239, section 1.3, are laminations made of AISI 304 or resistant plastic and are applied with screws on the bearings box
to protect the operator from contact with the rotating parts of the pump: in particular they cover the rear area of the pump body where the seals supports
are fi tted.
DANGER
It is absolutely forbidden to operate the LDPU if the safety devices have been removed.
1.7.4 Optional features: full fairing
The full fairing of the LDPU is made up of a cover made of AISI 304 shaped appropriately, according to the dimensions of the unit, and fully covers the
transmission parts during their operation, in order to protect the operators present on the plant layout, where possible, from the accidental contact with
the parts.
DANGER
It is absolutely forbidden to operate the LDPU if the safety devices have been removed.
1.7.5 Optional features: electric safety devices and pressure limiters
Upon specifi c request of the customer company it is possible to equip the LDPU with two kinds of safety systems:
•
pressure;
•
electrical;
In particular the electrician called by the customer to perform this connection and qualifi ed for the job, must design and make the electrical connections
in compliance with the electrical regulations in force.
The electrician called by the customer to carry out the connections above must also envision a general reset function after the activation of the emergency
state.
DANGER
It is absolutely forbidden to perform maintenance or repairs interventions on the LDPU, without having worn the PPE.
DANGER
It is absolutely forbidden to operate the LDPU after the occurrence of faults or malfunctions of the pump or equipment or devices connected to it. Dama-
ged safety devices must be replaced immediately. Never neutralise the safety devices.
