Electrical Consumption
In order to install a PS20 Non Stop melter, we should take into consideration
the total consumption of the installation, including the consumption of the
installed hoses and applicators.
Before connecting, make sure that the voltage that is being connected to the
melter is the correct one appearing on the equipment’s characteristics plate.
Connect the machine and check to see if it is well grounded.
Warning : Risk of electrocution. Even when the equipment is turned off,
voltage remains in the intake terminals, which may be dangerous during
internal equipment manipulations.
Non Stop drum melters include a lockable voltage disconnection switch,
which isolates the equipment from its power source. It is protected from
power surges and short circuits by means of magnetothermic switches and
it is equipped with personal protection from branching to mass by way of a
differential circuit breaker.
Consumption figures, according to melter and output configuration, are
included in the table in the section ‘Electrical power connection’.
Compressed air
As an option, a pneumatically activated by-pass valve or an air drying system
may be installed. If these are added to the system, a dry, unlubricated
compressed air network must be available, with a maximum pressure of 6 bar.
In the case of the air drier, this depends on the frequency of application, and
therefore consumption must be estimated for each case. Generally speaking,
we can give a maximum consumption value of 4.5 l/min for a pressure of 0.5
bar with a standard cycle setting (10 min standby / 10 s application).
