Pressing both arrow keys + at the same time results in the ESC function.
With the ESC function you can step backwards inside the menu and parameters
without saving the settings.
In order to leave all menus and submenus please press the ESC-button again and again
until you are back in the RUN-mode.

If the device is in the RUN-Mode and you press the arrow keys + at the same
time for at least 5 seconds, the key lock will be activated.
The display shows „sLOC“, blinking 3 times.
Now the adjusted settings can be read but not be changed.
For cancelling the key lock please press both arrow keys + for at least 5 seconds
again.

notes:
•The following examples and descriptions of the switching output 1 (SP1) refer to the
switching function „normally open“ (no). If the switching output 1 is set „normally
closed“ (nc) the states are reversed.
•The minimum range between the switching outputs (SP.1 and rSP.1) is 1% of the
nominal pressure; stated by the system.
•The smallest adjustable hysteresis is 1% of the nominal pressure; stated by the sys-
tem.
•All examples are effective for output 2, if this output is defined as switching output
(SP-2) also.

output
output
switch-point with release position
programmed parameters: SP.1: 250.0 bar
rP.1: 40.0 bar
An increasing pressure up to SP.1 (e.g. 250bar), switches the output according to the ad-
justed switching function (no or nc). This state remains also for higher pressure.
For decreasing pressure the switching state changes with the pressure value at rP.1 (e.g.
40bar). If SP.1 will be changed, rP.1 remains the same.
The minimum range between SP1 and rSP.1 is 1% of the maximum pressure.
switch-point with hysteresis
programmed parameters: SP.1: 50.0 bar
HYS.1: 20.0 bar
An increasing pressure up to SP.1 (e.g. 50bar) switches the output according to the ad-
justed switching function (no or nc). This state remains also for higher pressure.
For decreasing pressure the switching state changes after passing the hysteresis (e.g.
20bar). If SP.1 will be changed, the hysteresis HYS1 remains the same, that is the release
position is (SP.1 – 20)bar.

output

window function with release position
programmed parameters: SP.1: 250.0 bar
rP.1: 40.0 bar
Due to the window function, the monitoring of a defined pressure range is possible.
As soon as the pressure reaches the adjusted range between rP.1 (40bar) and SP.1
(250bar), the output switches according the chosen switching function (no or nc).
The switching state changes if the pressure leaves the adjusted pressure range.
The values for the switch-point and the release position have to be defined separately.
If only SP.1 is changed, rP.1 will remain the same.
window function with hysteresis
programmed parameters: SP.1: 50.0 bar
HYS.1: 20.0 bar
If the pressure hits the adjusted window between (SP.1-HYS.1) and SP.1 (50bar), the
output switches according to the adjusted switching function (no or nc). The switching
function changes when leaving the window. If SP.1 changes, the hysteresis will not
change, e.g. the release position is (SP.1 – 20)bar.
