Safety switch installation
(on versions without control box)
Mount the magnetic switches to the safety relay accord-
ing to this diagram found in the back of this manual.
Every motor contactor should be switchable by DC cur-
rent and powered by the 24VDC safe circuit.
All local regulatory rules must be followed. The installer
has full responsibility to make sure the local regulatory
rules are followed.
To make sure the safety switches work with the KDC
control panel, follow this procedure step by step:
• Ensure the cleaner is installed correctly and the
magnetic safety switch system on the side doors
is connected correctly according the electrical dia-
gram.
• Close both side doors and start the cleaner.
• To test the safety system, now start opening the
side doors by unscrewing the thumb screw. When
unscrewing, the safety relay should break the cir-
cuit and thus stop the motors.
•
It should take approximately 15 seconds to open
the side doors.
• When the side doors have opened, the drum
should have stopped rotating and it should there-
fore be safe to change the cleaning screens.
Motor installation (on 60Hz versions)
The KDC needs motors to be installed before it can
operate. Each motor must be installed with a DC mo-
tor contactor wired up to the safety circuit in the control
panel. This is to ensure the safety in operating the ma-
chine.
The KDC 4000 uses:
•
Auger KDC 4000 - 0,75 kW motor with N56C flange
• Drum KDC 4000 - 1,5 kW motor with N140TC
flange
•
Blower KDC 4000 - 4 kW motor with FF215 flange
The KDC 8000 uses:
• Drum KDC 8000 - 2,2 kW motor with N140TC
flange
•
Auger KDC 8000 - 1,1 kW motor with N143T flange
•
Blower KDC 8000 - 4 kW motor with FF215 flange
Ensure that the magnetic safety switch system is in-
spected and maintained regularly according to the
users manual for the cleaner.
