DCE 2000 Series Dust Collectors

eex controls
When the dust collector is to be installed in a hazardous area where there is any
risk of fire or explosion, the collector will be marked for the area(s) it can be safely
used within (refer to collector serial nameplate). The collector may be fitted with
either of the following control systems:
EExd solenoids and remote controller
When this option is fitted, the dust collector has its solenoid valves in an
EExd IIb T6 enclosure mounted directly to the unit. A controller, housed in
an IP66 box, is supplied loose. This must be installed in a safe area and
connected to the solenoid valves on the dust collector using suitable cabling
(not supplied).
It is recommended that cable with a core size of 2.5 mm² is used.
The maximum length of cabling that can be used is 100 m.
Instructions for setting up the controller are the same as those for the standard
controller.
PT Controller
The PT Controller is a pneumatically operated device which operates the
diaphragm valves in sequence, therefore the need for an electrical supply
is eliminated.
The controller is supplied complete with air regulator and is normally bracket-
mounted directly to the unit.
For PT Controller connections and set-up, refer to Publication 2697.
antistatic earthing
It is particularly important on collectors having
antistatic features and/or explosion stiffening, that the
earthing post (located adjacent to the symbol, shown
opposite) is properly connected to earth, using the
brass screw provided, to prevent any static build-up
(refer also to Fig. 1).
Collectors with dust containers will have two
connection points, located on the collector
and the base.
