Error handling

A check identifies available input signals after quitting the COMMIS
(commissioning) menu. We differentiate between two cases if one of the input
signals previously acquired is missing due to short-circuit or open circuit:

Case

Description

Display

1

At least 1 input signal is
missing, but calculation is still
possible.

Fault symbol

. The calculated values are

displayed (Info pictures and INFO menu
(Inputs/outputs)).

2

At least 1 input signal is
missing, and calculation is not
possible.

Fault symbol

.

Values according to the table below.

If calculation is not possible (case 2), the following

predefined values are displayed:

Calculation not possible

Function

Value

ENTH x

0 kJ/kg

ABSH x

0 g/kg

ENTH D

−

50 kJ/kg

DEWPNT 0

°C

The relevant input is not monitored later if one of the input signals is missing after
you quit the COMMIS (commissioning) menu.

See section 5.4 on how to handle input errors.
