Collectors with integral fan
When the collector is fitted with an Controller, the fan will be wired to the terminal
box located on the front of the collector. These terminals will need to be wired to a
suitable control panel for the type of fan motor supplied. This control panel should
be designed to comply with local legislation for electrical installations (refer also to
‘Overload protection’ and ‘Control of ancillary equipment and interlocks’).
When the collector is fitted with a Power Box, the fan will be wired to the Power Box.
Connect the incoming three-phase supply to the isolator of the Power Box.
Details of standard fan motor supply voltage are given in Table 6 (refer to
‘Specification’ section).
Overload protection
All feeder circuits should be adequately protected with suitably-rated fuses and
contactors with integral overload protection.
Control of ancillary equipment and interlocks
Discharge equipment such as belt feeders, rotary valve or screw conveyor should be
separately controlled but interlocked with the collector controller (refer to figure 7).
If the collector is fitted with a Power Box, this can be configured to operate a complete
dust collector system (e.g. fan motor, screw conveyor, rotary valve etc.) and accept
inputs from other devices (e.g. PLCs, level probes, explosion relief panel detectors
etc.). Where the Power Box is used for the complete system, all necessary interlocks
will be built into the system.
The design of the electrical circuitry controlling equipment associated with the collector
should be such that breakdown of any one of the associated pieces of equipment
does not cause a complete blockage of the collector. For example, should the motor
