Note: Not all parameters are visible at any one time. Many parameters are
dependent on other parameters. Only relevant parameters are displayed
as this reduces clutter on the screen. The screens shown here are typical
and may not be exactly what you will see.
1.1 Start-up
On Start-up, the display will show the splash screen.
 Proceed to the Main Menu by tapping the Home icon (bottom right).

Parameters can be edited in several different ways, depending upon their nature.
2.1 Numeric
When you tap on a button showing a numeric parameter, an editor window
opens:
e.g.
1 Present value of paramete
r
2 Use the ke
y
pad to enter a new value
3 Cancel the entr
y
(
present value remains unchan
g
ed
)
4 Backspace the value in field 1
5 Enter the selected value
(
parameter is chan
g
ed to new value
)
 Initially, the present value is shown. In the above example the parameter
called Use Program is set to the value 2.
 Tap on the numeric buttons to enter a new value, then tap the green tick
key. The editor will close and return to the previous screen, showing the new
value entered.
 If you enter an illegal value, a warning message appears and the parameter is
not changed. Close the warning message by taping on the red X key in the
top right corner.

2.2 Radio button
This type of parameter has only two options.
e.g.
Standard Extended
Features
 The presently selected option is highlighted. In the above example the
parameter called Features is set to Standard.
 Each time you tap on the button, the parameter is set to the other option.
2.3 Multi-option
This type of parameter has more than two options.
e.g.
I/OSource
DISCRETE
 The presently selected option is shown. In the above example the parameter
called I/O source is set to DISCRETE.
 Each time you tap on the button the parameter will change to the next option
in the list. After the final option, the list starts again with the first option.
2.4 Check box
This type of parameter is either on (box ticked) or off (box clear).
e.g.
Stop
onFault
 In the above example the parameter called ‘Stop on fault’ is on.
 Each time you tap on the button the parameter toggles between on (box
ticked) and off (box clear).

This section describes the hierarchy of menus which allow access to the parameters.
Not all parameters are visible at any one time. Many parameters are dependent on
other parameters. Only relevant parameters are displayed as this reduces clutter on the
screen. The screens shown here are typical and may not be exactly what you will see.
Wherever you see the symbol in this section, this indicates that the
parameter is only available if Extended features is selected in the Configure menu.
The Main menu is the hub from which all sub-menus are accessed.

Valves
There are eight valve outputs on the EN7000. Each valve is assignable to
a program interval as described below. To assign a valve to a program
interval, tap either button in the program interval row. In the figure above,
WAV is assigned valve 1, Motor is assigned valve 2, and the AUX output
during the Squeeze interval is assigned valve 3. The table below shows
constraints of how the valves may be assigned.

3.2.7.1. WAV
The WAV (Weld Air Valve) turns on at the start of the sequence
and turns off at the end of Hold. Valves not being used for the
WAV function may be used as AUX valves. WAV settings will
always override any AUX setting assigned to the same valve.
3.2.7.2. MOTOR
This feature is available in Seam mode only. For normal seam
welding, the MOTOR output turns on according to the 2nd Stage
setting in the Configuration menu and turns off at the start of the
Hold interval. If the Roll-spot option is selected, the MOTOR
output operates during the Off interval only. Valves not being used
for the MOTOR function may be used as AUX valves. MOTOR
settings will always override any AUX setting assigned to the same
valve.
3.2.7.3. AUX
An AUX valve may be programmed to turn on during any interval in
the welding sequence. Repeat mode must be enabled in the
Options menu to access the OFF interval. WAV and MOTOR
settings will always override any AUX setting assigned to the same
valve.
