WATER RESET FUNCTION Press on ( I ) to shut water off five (5) minutes
after machine shuts down. Selecting this
function will insure that the inlet cutting
water is shut off following a shutdown fault.
This can prevent water from leaking past a
damaged water seal following an overstroke
shutdown caused by a seal failure.
IDLE SHUTDOWN FUNCTION Set timer to stop machine after 5-30 minutes
of inactivity (machine not stroking). This
feature saves energy by automatically shutting
down the intensifier if it is not being used.
For more information, refer to Section 3, Operation , of this manual.
(
1) Standard machine, start-up after machine has been E-stopped:
Safety dump valve will be open. It will close 3 seconds after the T/W
begins stroking. The pump will be held in low pressure for 20 seconds
after motor is started after which pressure will go to high if high is
selected, otherwise will stay in low.
The purpose for this is to allow entrapped air to be bled from any HP
cylinder that has been maintained to avoid hot air burning the plunger
seals.
(2) Standard machine, start up after normal stop: Safety dump valve will
be closed, pump will be held in low pressure for 20 seconds after motor
is started, after which the pressure will go to high if high is selected,
otherwise will stay in low.
(3) Machine equipped with hp transducer, start up after E-stop: same as
(1) above.
(4) Machine equipped with hp transducer, start up after normal stop: If
pressure is allowed to bleed through orifice to below 1000 psi, dump
valve will open and start up will be like (1) above, if pressure is not
allowed to bleed, start up will be as (2) above.
● The display screen will always default to the Run screen after being on any
other screen more than 5 minutes.
NOTE
The high-pressure dump valve will not close if the air supply is OFF.
