7.3.1 Line Monitor
• If you select
On
for
LB
, an input current < 0.2 mA will be registered as a lead break (section 6).
• If you select
On
for
SC
, an input current > 22 mA will be registered as a short circuit (section 6).
If you wish to process the
0.2 mA input values as measured values, you must deselect the lead
breakage detection (Off LB). If not, an fault will be signalled within the measuring range.
7.3.2 Zero Point and Conversion Factor
The device measures in mA. If you have selected different
units
(section 7.2), the device calculates
the measured value in the selected units using the parameters
Zero point
and
Conversion factor.
The parameters for your application must be determined according to the following formula:
An arbitrary value between -15 mA and +15 mA can be set as the
Zero point
, and values between
0.100 and 5000 as the
Conversion factor
.
The following includes examples where the formulas are applied.
Measured value in
the selected units
= (Original measured value [mA] – Zero point) x Conversion factor
