3 General Description
The ‘Tool HP’ has been designed to enable high powered
tools to be interfaced into the ‘iVAC Pro System’.
High power tools are those power tools that have high start up
surge currents or require more than 20Amps operating
current. It also includes power tools that operate at voltages
above 230Vac or are wired for three phase operation.
There are three main items to the ‘Tool HP’.
‘Tool HP’ module.
Clip On Current Transformer and cable.
AC Adaptor. 115Vac to 23Vac 0.2A UL/CSA Approved
In order to detect when a power tool is in operation the Clip
On Current Transformer is clipped onto one of the current
carrying power leads to the power tool. There is no electrical
connection; it is purely a magnetic pick up. This may require
access to a distribution box. (As shown in Fig. 3)
When the power tool is turned on or off, the ‘Tool HP’ will
transmit an On or Off signal to the ‘iVAC Pro Switch’, which
in turn controls a dust collector.
Active Current threshold; this is the level of current to the
power tool that will cause the ‘Tool HP’ to identify that the
power tool is active. This threshold is adjustable from 0.5
Amps to 3.5 Amps.
