2.5 Counter/Integrators
These are not electrical measurement inputs (hardware), but channels which
are calculated by the paperless recorder (software).
22
The terms counter and integrators encompass the following elements:
-Counter
- Integrators
- Operating time counter
- High-speed counter (hardware counter)
- Flow rate quantity

can be implemented by entering a negative weighting (e.g. a weighting factor
of -1).

corresponds to a flow rate of 0 … 1000 liters/sec
Minimum size
of the input
signal
-Time base 1sec
- Weighting 0.001 (conversion from liters to m³)
- Display of the integration value (flow rate quantity) in m³
This type of flow measurement is based on an analog input. Fast
binary inputs offer another possibility (high-speed counters).
v Chapter 2.5.5 “Flow rate quantity”
Entering a threshold (amount of the threshold value) has the effect that
integration takes place only when the value has been exceeded. No
integration will occur on falling below this value. The advantage of integration
with a threshold value larger than 0 is that possible noise from a transducer
can be suppressed in this way.
23
2 Instrument Description
2.5.3 Operating time counter
The operating time counter will count how long a selected binary input or one
of the binary signals is closed. The time can be displayed in sec, min, hr and
days.
2.5.4 High-speed counters
Counter inputs The first two binary inputs of each module (B1, B2, B9, B10, B17, B18) can be
counted. Binary inputs are available if the module is fitted with 3 analog inputs
and 8 binary inputs.
Counting
frequency
Weighting Counted pulses can be weighted (by multiplying them by a factor). A down
Max. 10kHz
counter can be implemented by entering a negative weighting (e.g. weighting
factor -1).
2.5.5 Flow rate quantity
This makes used of the options of existing counter function to determine flow
rate quantities with the high-speed counters over the assigned time intervals
(the "pulses within the time base" are multiplied by the "weighting").
The flow rate quantity only appears on the paperless recorder.
It is not saved.
Counter inputs The first two binary inputs of each module (high-speed counters B1, B2, B9,
B10, B17, B18) can be used to measure the flow rate quantity (pulse counting).
Binary inputs are available if the module is fitted with 3 analog inputs and 8
binary inputs.
Time base sec, min, hr and day
The time base defines the duration for which pulses will be counted (gate time)
and the display interval of the flow rate quantity.
Counting
frequency
Weighting Counting pulses can be weighted (by multiplying them by a factor). A down
Max. 10kHz
counter can be implemented by entering a negative weighting (e.g. weighting
factor -1).
24
2.5.6 Recording period of the counts
For all counters, integrators, operating time counters, and high-speed
counters, the counters are concluded and the counter states are stored and
restarted after an adjustable amount of time (recording time period). The
counter states of the most recently completed recording period can be
numerically displayed.
The following counter/integrator types are possible:
-Periodic
In addition, the time period (from 1 min to 12 hrs)must be selected in the
parameter Configuration
Period.
-External
In this case, the counter/integrator is updated only when the selected
control signal is active (e.g. binary input is closed). When the control signal
is deactivated (e.g. binary input is opened), the counter/integrator value is
saved and reset to 0.
-Daily

2 Instrument Description
2.5.7 Reset counters
Periodic reset There is a recording time period for each counter, integrator, operating time
counter and high-speed counter. At the end of this period, the current data
(value and time) are saved and the value reset to 0. Then the next time period
is recorded.
The overall and annual counters/integrators are an exception. These are saved
whenever any count/integration has been completed, but not reset to 0. This
means that they can be evaluated in the evaluation software PCA3000 as well.
External reset A control signal can be configured for all counters, integrators, operating time
counters and high-speed counters. The signal generates a reset of the counter
states to 0 without previous values being saved. The period for the summation
will be restarted at this point. This means that after the test run of an

values that are not required are eliminated.

The parameterization menu makes it possible to set counter states to a
specific value. The preconditions is that a user is logged in to the device.
When the value is entered after editing, a message with the new and the old
count value is entered in the event list.
The time period for the counter/integrator summation will not be restarted. The
previous counter/integrator values will also not be saved.
If you wish to save the previous counter/integrator values, you
must execute the function “Save all + update CF.” in the menu for
the memory manager.
In this way, the recording can be freshly started for individual counters/
integrators, e.g. after the test run of an installation; the test run values that are
not required will be eliminated in the process.
2.5.8 Response to setting the time
When the time is set, all counter states are completed and saved and, value is
reset to 0, and the recording period is restarted.

2.5.9 Response to instrument reconfiguration
When the instrument is reconfigured, the current counter/integrator recording
periods remain unaffected. The counter/integrator values will not be reset to 0
and the recording period will not be restarted.
The values can be deliberately reset, via the “Parameterization”
menu.
2.5.10 Response to reconfiguration of the counters on the instrument
If a counter/integrator on the instrument is reconfigured, then only the affected
counter/integrator will be concluded, saved, reset to 0 and have the recording
period restarted.
If anything is changed through reconfiguration in the menu Configuration
Counters/integrators General settings, then all counters/integrators are
concluded, saved, the values reset to 0, and the recording period is restarted.
2.5.11 Response to reconfiguration of counters with setup program
If a counter/integrator is reconfigured, the setup program will conclude and
save all counter states and reset the value to 0 and the recording period is
restarted.

2.6 Math/Logic Module
The math and logic module is available as an extra. Like the counters/
integrators, the math and logic module are channels that are not available as
hardware but are calculated by the instrument software.
The math and logic module consists of two parts:
- the math module for calculating analog values and
- the logic module for linking Boolean values (0 or 1).
Math module The math module provides 18 measurement inputs for calculating new
“virtual” channels.
For the calculated channels, separate math channels are provided in addition
to the internal analog inputs. In configuration, you have to activate the required
math channel in the group configuration and thus assign it to a group.
Configuration
Setupprogram How a math channel is formed is determined through the setup program.
As variables for the formulae, the following may be available:
- Analog inputs
- Binary inputs
- Counters/integrators
-Alarms
-Errors
If counter/integrator values are used for calculation, then please note that their
accuracy is reduced, since, in this case, two different data formats will have to
be used for calculation. Counters/integrators are calculated in double-float
format (8 bytes per value), whereas the math module employs a single-float
format (4 bytes per value) according to the IEEE 754 standard. Nevertheless, it
is possible to include these values in the math module.

2 Instrument Description
The following fixed functions are available:
-difference
-ratio
- relative humidity
- moving average
For the moving average, the reference channel has to be entered (in most
cases, the analog input) and the time (in minutes). They will be used to
calculate the moving average.
The following operators and functions are available for formulas: +, -, *, /, (, ),
SQRT(), MIN(), MAX(), SIN(), COS(), TAN(), **, EXP(),
ABS(), INT(), FRC(), LOG(), LN().
On going above or falling below the scalable values, the math channel is
treated as for “out-of-range”.
Formulas are entered in the PC, in the setup program. It is not possible to edit
math formulas on the instrument.
Further information can be obtained from the instructions on the
setup program (59492).
Logic module Up to 18 channels are available for the logic channels.
As is the case with all the other binary signals, the calculated digital (Boolean)
values can be used for different functions:
- recording in event traces,
- as a control signal for display switch-off,
- clock time synchronization,
- operating time counter,
- externally controlled counters/integrators
- counter/integr. reset
- event mode,
- for output to a relay and
- as count input for a counter.

Following are some of the variables available for formulas:
- Binary inputs
- Logic channels
-Alarms
-Errors
These functions can be used for formulas:
-! (NOT)
-& (AND)
-| (OR)
-^ (XOR)
- / (rising edge)
- \ (falling edge)
-( (open bracket)
-) (close bracket)
Further information can be obtained from the instructions on the
