4.7.10 Possible ELCH Error sources
Working with ELCH, different sources of errors are possible:

“ 310, ELCH set value initialization not complete ”

The value you selected as independent variable is not allowed for this
purpose, e.g. values which are calculated from others. Please refer to the
operation manual of the individual module. You can use every command,
which also offers the compound “
:MEAS n ”

The given START and STOP values either belong to different commands
or/and to different modules.

The module involved is not or not completely initialized.

The module involved is not switched on.

You did not select the module which operates the independent variable
( :SLOT n ) when starting ELCH

“ 311, ELCH read value(s) initialization not com-
plete ”

You tried to use a read value that is not a measurement value (e.g. p-share).
You can use every command which offers the compound “ :ACT? ”

The selected module was not initialized correctly (e.g. read resistance with a
TED but the module is switched to an AD590 temperature sensor).

You specified e.g. 3 dependent values “ :ELCH:MEAS 3 ” but initialized only
2 : “ :ILD:MEAS 1 ”; “ :TEMP:MEAS 2 ”

“ 312, ELCH was stopped ”

You gave a stop order to ELCH

An error has occurred in a module (e.g. interlock open)
