This activates the controls by turning on the main control relay. The controls
must be on before any other commands are accepted. See note1 under
Required RPC Connections for information on turning on the controls when
this input is absent.
The remote E-stop terminals provided are in series with the pump E-stop
circuit. Normally these would be wired to dry contacts on an E-stop at the
remote control source. Connection to this E-stop is the responsibility of the
integrator. One set of dry contacts are also provided on the back of the
Hypertherm E-stop button. These contacts open when the Hypertherm E-stop
button is activated.
The remote pump on input performs a sequential startup of the entire pump.
This turns on the inlet water, and main motor. After the motor is at speed the
intensifier will start stroking at low pressure first for a preset time and then
switch to high pressure. If the pump is in cooling mode, pressing the pump on
will start the intensifier stroking.
This input turns the intensifier, motor, inlet water, and cooling fan (if present)
off. After the pump is shut down, you must choose cooling mode or pump on in
order to start the pump. For stand-by condition in between programs, it is
recommended to leave the pump running.
Cooling mode turns the motor and inlet cooling water or cooling fan logic on.
Cooling mode also turns off the intensifier if it is running.
Status indicator of controls circuit. The controls are on when 24VDC is
present.
Status indicator of remote mode. The pump is in external pressure control or
remote pump control mode when 24VDC is present.
Status indicator for fault monitoring. Any fault condition that displays a
message on the screen or flashes a yellow or red light will cause this output to
turn on. 24VDC indicates a fault is present.
Status indicator for pump motor. The remote pump indicator will turn on any
time the motor is running.
