Channel Functions; Channel Designation - Ahlborn ALMEMO 710 Operating Instructions Manual

13.2 Channel functions

Since on ALMEMO
ALMEMO ® connector itself, the user will not normally need to reprogram each
time. Programming will only be necessary e.g. if sensor errors are corrected, if
your own sensors are scaled, or if certain limit values are stipulated; in these
circumstances there are comprehensive setting functions available.
Selecting ´Channel functions´ opens a further selection list; here, if the sensor
in question is connected, all the parameters listed for a particular channel can
be entered and / or modified,. This overview can also be accessed from the
menu ´Measuring channel´ by selecting the option ´Settings´. (see 12.1)
13.2.1 Channel designation, function abbreviation
13.2.2 Measured value smoothing
13.2.3 Maximum / minimum values
13.2.4 Averaging functions (average value, mode, number)
13.2.5 Measured value output (output function, cycle factor)
13.2.6 Channel locking (locking level)
13.2.7 Limit values (maximum, minimum, hysteresis)
13.2.8 Actions triggered by limit value infringement
(action maximum / minimum, relay maximum / minimum)
13.2.9 Analog output (start / end)
13.2.11 Scaling values (base value, factor, decimal point shift)
13.2.10 Correction values (zero-point, gain)
13.2.12 Units
13.2.13 Quantities Function channels
13.2.13.4 Reference channels, multiplexer
13.2.13.6 Element flags
13.2.13.7 Minimum sensor supply voltage
13.2.14 Channel compensationn
Please note that series sensors by default have the locking mode enabled to
protect them against unintended alteration; if modification really is required this
locking mode must first be lowered to an appropriate level. (see 13.2.6)
Selecting the input channel
To view or to program a sensor's parameters it is necessary via selection box
´Select channel´ to specify the desired input channel. Only sensors actually
connected and channels actually activated can be processed. To activate new
channels it is necessary in ´Settings´  ´Sensor settings´  ´Quantities´ to ac-
tivate an inactive channel and, if necessary, change the range.

13.2.1 Channel designation

The first function in this list is ´Channel designation´. Each measuring channel
can be assigned a designation; this must be alphanumerical, using any ASCII
characters (except ; / | #); for D7 sensors it can be up to 20 characters, other-
wise up to 10 characters; it should denote as clearly as possible the type of
sensor, measuring location, and / or purpose. This designation is included in all
® devices all sensor programming is stored in the
Channel functions
