FOCKE MELER GLUING SOLUTIONS INSTALLATION

Electrical Consumption
In order to install a PS20 NS+ melter, we should take into consideration the to-
tal 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, volta-
ge remains in the intake terminals, which may be dangerous during internal
equipment manipulations.
NS+ drum melters include a lockable voltage disconnection switch, which iso-
lates 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 cir-
cuit breaker.
Consumption figures, according to melter and output configuration, are inclu-
ded 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 com-
pressed 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).
