Leak rate log. 0 ... 10 V; logarithmic;
in the selected unit
The upper limit (= 10 V) and the scale (V / decades)
are set via the parameters "Exponent upper limit" and
"Analog output scaling".
For example:
Upper limit set to 1 x 10
-5
mbar l/s (= 10 V). Scale set
to 5 V / decade. The lower limit is thus 1 x 10
-7
mbar l/
s (= 0 V). The logarithmic output function of both the
slope in V / decade as well as the upper limit (10 V
limit) can be set. This results in the minimum
displayable value. The following slopes are available:
0.5, 1, 2, 2.5, 3, 5, 10 V/The higher the selected slope
value, the smaller the displayable area. The upper
limit is the same for both analog outputs. Depending
on the selected leak rate unit there is a different
absolute limit.
Set by interface The output voltage can be specified for tests with the LD log command 221.
Leak rate mantissa hyst. 0.7 ... 10 V; linear;
in the selected unit
Useful only if the other analog output is assigned
"Leak rate exponent". Through an overlap of the
mantissa in the range 0.7 to 1.0, a constant jumping
between two decades is prevented. 0.7 V
corresponds to a leak rate of 0.7 x 10
-x
. 9.9 V
corresponds to a leak rate of 9.9 x 10
-x
.
10.2.3 Configure digital inputs
These inputs can be used to operate the device with a programmable logic controller
(PLC).
The digital inputs PLC-IN 1 ... The available functions can be assigned in any way
necessary to the 10 I/O module.
– Active signal: typically 24 V
– Inactive signal: typically 0 V.
The 24V output of the I/O module can be used as an active signal.
Every function can be inverted.
