Single-phase drive module
The Single-phase drive module, in addition to the previously mentioned items is
equipped with an inverter error signal light, which illuminates if the inverter goes into
overload for example.
The three phase unit has a phase detection module with prevents the power from coming
on unless the phases are wired to run the unit in the correct direction. To correct the
wiring there is a phase reversal switch on the front panel of the three phase units in place
of the inverter error indicator on the single-phase unit.
Fixed to the sides of the control module are a series of polarized plugs, each is color
coded to suit the mating socket.
Each machine is equipped with a water pump, used as a booster pump to help ensure
consistent water pressure, and as such the unit will not run unless the water pressure
switch is closed. For maintenance the water pressure switch can be over ridden using the
supplied “dummy” plug, attached to the side of the module.
Each machine is equipped with a water supply module which is operated by a signal from
the control module to open and close a solenoid valve which starts and stops the water
flow.
Each machine is supplied with a wired remote pendant, allowing the operation of the
machine from up to 10 feet from the connection. The remote provides stop / start
functionality only. The machine will NOT run without either the remote being attached,
or the remote “dummy” plug being attached, the “dummy” plug is attached to the side of
the module and color coded similarly to the water pressure “dummy” plug
