1.5 SECURITY AND CONTROLS
1.5.1 CONSTRUCTION STANDARDS
The whole electrical supply and control part has been manufactured in compliance with the EN60204-1
standards, (Electrical equipment of machines). The electrical components installed inside the dangerous
zones are in accordance to EN50014 standards (Electrical apparatus for potentially explosive atmospheres -
General requirements), EN60079-10 (Explosive atmospheres. Classification of areas. Explosive gas
atmospheres), EN 60079-17 (Explosive atmospheres. Electrical installations inspection and maintenance),
EN60079-14 (Electrical apparatus for explosive gas atmospheres. Part 14: Electrical installations in
hazardous areas (other than mines) and particularly in appliance with the following standards:
• EN60079-11 (Explosive atmospheres. Equipment protection by intrinsic safety "i"). These systems
have been used to interface all ports from AD zone with the electrical control system.
• EN60079-7(Explosive atmospheres. Equipment protection by increased safety "e") and EN60079-18
(Electrical apparatus for explosive gas atmospheres. Construction, test and marking of type of
protection encapsulation "m" electrical apparatus). These systems have been used for the vacuum
pump engine and for the actuators installed in the hazardous zones.
The cabinet part containing the electrical supply and control devices is tight and completely separated from
the rest of the equipment. The eventual presence of inflammable gas is avoided by the suction system
inside the dosing section.
1.5.2 ELECTRICAL SAFETY DEVICES
Safety devices are placed on the power electric panel and are accessible by opening the rear door of the
equipment:
• FUSES:
FS1 and FS2 = T2A 500V 6,3x32 (1500A). They are used for the protection of the transformer's
primary, which supplies the solenoid valves and the 220 VAC apparatus. The indicated values refer
to the equipment supplied with a voltage of 380V 3ph 50Hz.
FS3 = T2A 500V 6,3x32 (1500A). It is used for the 220 Volt secondary of the transformer supplying
the electronic rack and the 220 Volt uses.
FS4 = T2A 250V 5x20 (1500A) IEC127. It is used for the protection of the 24 Volt secondary of the
transformer supplying the solenoid valves.
FS5 = T5A 250V 5x20 (1500A) IEC127. It is used for the protection of the 24 Volt secondary of the
transformer supplying the general ON/OFF switch of the equipment.
FS6 = T1A 250V 5x20 (1500A) IEC127. It is used for the protection of the 24 Volt secondary of the
transformer supplying the solenoid valves.
FS7 = T1A 250V 5x20 (1500A) IEC127 It is used for the protection of the shut off valve.
• CONTACTOR:
K1 = contactor K1 is used for the cutting of the power to the pump and for the retention / release
of the control signals the start / stop of the plant.
• MAGNETOTHERMIC SWITCH:
IA1 = It is used for the magnetothermic protection of the vacuum pump engine.
