• Service data: Status information that can be evaluated by JUMO service
personnel for diagnostic purposes can be read here.
In addition, the
"Service count." and "Internal data" are displayed. The
service counters record the number of switching operations executed by the
digital outputs. The
voltage of the buffer battery and the board tempera-
ture are shown in the "Internal data".
8.2.6 Calibrating the touchscreen
To ensure precise and reliable operation of touchscreen control, you can open
the "Calibrate touchscreen" menu.
The device then prompts you tap 4 points on the touchscreen.
Simply follow the instructions on the display.
8.2.7 Digital sensors
The assignment table (list of all configured inputs for digital sensors) is displayed
here. Up to 6 digital sensors can be connected and operated via the selected
serial interface. The link status of the configured sensors is displayed in the form
of a symbol in the right column.
CAUTION!
A buffer battery is built into the device. Its purpose is to maintain data when the
device is switched off or if the voltage supply is interrupted. If the battery ap-
proaches the end of its operating life (approximately 7 years) then a battery
prealarm will indicate that status. When the battery is empty a battery alarm will
indicate that status. The battery must be exchanged before it is empty. The bat-
tery must be exchanged by the JUMO Service department! In this case, send
in the device!
