Power-up functions
·
In order to access these functions, press and hold the switch while powering up the instrument.
·
As long as the switch is held, the LEDs show a repeating sequence of patterns, where each pattern indicates a function.
·
All indications in this sequence are flashing (0.2 sec on, 0.2 sec off).
·
Each pattern is shown for a number of seconds; in the table below the column
Hold time
indicates the time frame within
the sequence where the LEDs show the associated pattern.
·
To start a function, release the switch when the LEDs show the pattern of the required function.

Reading control mode
·
By briefly pressing the switch 2 times with intervals of up to 1 second in normal operation mode, the instrument shows
its current control mode with a series of consecutive LED indication patterns.
·
The number of flashes corresponds to the current value of parameter
Control Mode
(see
).

l
number of flashes indicates the units of the parameter value
Examples:
·
for value 1 (control mode 'Analog input'), the green LED will flash 0 times and the red LED 1 time
·
for value 22 (control mode 'Valve Safe State'), the green and red LED will each flash 2 times
Changing control mode
·
By briefly pressing the switch 4 times with intervals of up to 1 second in normal operation mode, the instrument enters a
state in which the control mode can be changed.
·
This is done in 2 steps, each represented by a LED indication pattern (green or red; see table below).
·
The number of flashes corresponds to the available values of parameter
Control Mode
(see
).
·
At the start of each step, the according LEDs starts flashing fast (0.1 second on, 0.1 second off). By pressing and holding
the switch, the associated action is started and the flashing slows (05. seconds on, 0.5 seconds off).
