MANUAL OPERATION OF THE DISPLAY VERSION
30.30.01.00956/01 www.schmalz.com EN | 19
In version V8, the pressure is positive and vacuum is negative; however, the positive/negative sign is
not displayed. You can determine whether the value is positive or negative using the table due to the
presence of a decimal point.
The switching threshold SPx/FHx and rPx/FLx in the operating menu is displayed based on the same
method.
If an error status is active, it is indicated in the display through a periodic switch with the measurement
value. For recognition purposes, a prefix “E” stands for error, followed by the error number (see list in
chapter 8.1).
One exception is error 7 (operating voltage too low): in this case “E07” will be permanently indicated in
the display and the switch will delay further user entries until the operating voltage has reached the
necessary level again.
6.1.2 Navigating in the menu
The basic menu can be reached from the basic status by pressing the SET button.
To scroll through the menu press the SET button.
When the desired menu item has been found, select it using the MODE button.
If there is a submenu (“AF” and “INF”), this can also be browsed in the same manner using the SET
button.
By pressing both buttons at the same time, it is possible to quit the menu at any point.
6.1.3 Editing the parameters
If a menu item has been selected, the current value will firstly appear in the display. With parameters
that can be set, the whole value or lowest number will flash and can be changed by using the SET
button. When doing so, the possible settings are run through cyclically.
With version VP8, the values of the switching thresholds SPx/FHx and rPx/FLx can be positive
(pressure measurement range) as well as negative (vacuum measurement range). In this case, the
desired range of the new value is set at the start of the editing process. The text “PrS” for pressure or
“UAC” for vacuum will firstly flash and can be selected accordingly.
For numerical values that consist of three numbers, the MODE button can be changed for the next
higher number.
At the end of the editing process, the MODE button is pressed again after the last number. The new
value then appears for two seconds in the display without flashing.
If the new value is invalid, the display will instead receive a message and the old value is retained:
„Oor“ (out of range) means that the new value is generally out of range, for example, SP1> 8.0
bar in the variant VP8
„InC“ (inconsistent) means that the value collides with the current setting of another
parameter, e.g. rP1> SP1
To cancel the editing process, both buttons can be simultaneously pressed at any time.
