Installation, Operation and Maintenance Manual
Dalamatic Insertable Dust Collectors – Series DLM V
Ex 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:
•
E
x
d solenoids and remote controller
When this option is fitted, the dust collector has its solenoid valves in an Exd
IIb T6 enclosure mounted on to the collector body. A controller, 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 on to the side plate of the dust collector body.
For PT Controller connections and set-up, refer to Publication 2697.
Explosion relief
Explosion panels, if fitted to upstand housings, must be relieved
and vented to a safe area in accordance with Factory Inspectorate
recommendations. The vent area is only suitable for the upstand housing
volume and not the equipment being served.
Insertable dust collectors suitably stiffened for explosion pressures
should be used.
Installation check list
Ensure the Dalamatic collector is securely bolted over the aperture.
Ensure compressed air supply is installed correctly and free from leaks.
Ensure electrical supply is installed correctly and complies to local
legislation.
