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.

operation modes of the switching outputs
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.
switch-point with release position
programmed parameters: SP.1: 250.0 bar
rP.1:
40.0 bar
output
release position
switch-point
pressure [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.

output
pressure [bar]
switch-point
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.
