7. 3 Calibration function

This func tion allows to acti vate a field calibrati on of linear input for s train-gauge
or potentiometer. Different calibration options are available and may be
selected by parameter, according to type of sensor/transducer and its relevant
application. To activate calibration procedure, enter configuration mode, select
the parameters group “Analog Inp.”, select Calibration parameter and chose
one of the available options pressing “Sel”. Following calibration options are
available:

User manual - DP400S - 15

• Sampling value. This proceeding performs a calibration of the analog input
on two points of the scale taking as reference two known values (for example
for a load cell these values could be Zero balance and Reference weight). It
is possible to link the calibration lower limit (parameter 6 Lower lim.) to the
minimum val ue of the sensor or to th e minimum position o f the potentiomet er
while the ca libration upper lim it (parameter 7 Upp er lim.) may be linked to the
max value of the sensor or the maximum position of the potentiometer.

Press “m” to calibrate lower limit and “n” to

• Full-scale % value. This proceeding is available for 6wires (4wires+2 wires
calibration) strain-gauge sensors and for Melt transducers. It is possible to
calibrate reading of analog input by choosing the percentage of the full-scale
value at which the calibration of the upper limit will be performed. At first
the operator will be asked to select the percentage for the calibration of
the upper limit. Afterward the lower limit value and upper limit value (% of
full-scale value) will also be calibrated, as for the sampling value. The two
calibration wires of the sensor can be connected to relay of output Q2 to
perform a semi-automatic calibration. In this case it is necessary to select the
option Calibration % on parameter Alarm 2 - Type of alarm. If contact Q2 will
not be used to generate sensor calibration signal, it is possible to short-circuit
externally the t wo wires, waiting for s tabilization of rea ding on the device and
then proceeding to calibration of upper limit.

Selecting 16 s teps on parameter 17 V/I custom and connecting a linear sensor
it is possible to customize the linear input for a max. of 16 steps. On parameters
xx-Input value it is necessary to enter the value of the input to which the value
selected on the corresponding parameter xx-Custom value will be related.
EExample: sensor 0 -5V.

04-Input value => 5.000V 04-Custom value.=>1000mBar
At each value in Volt (input) a value in mBar (customized) is related: if the s ensor
supplies 2V the device visualizes 100mBar, if it supplies 4V the device visualizes
500mBar. For intermediate tension values the value in mBar is calculated
linearly between the entered values containing it: 1V = 50mBar, 3V=300mBar
and 4,5V=750mBar.

9 Data logger

DP400S features a basic data logger function which can be enabled on
parameter 109 Data logger. After the initial start-up following the switch-on,
the device will start to save process data on EEPROM according to a selected
time basis. Sampling time must be selected on parameter 110 Datalogger
time. Stored data may be read via Modbus protocol starting from address 6001
(MSW) or 9001 (LSW) (see following section of this manual). The following table
provides info about the stored data:

10 Serial communication

DP400S is equipped with RS485, it can receive and broadcast data via serial
communication using MODBUS-RTU protocol. The device is configured as
a Slave. This function enables the control of multiple devices connected to a
super visory system . Each controller resp onds to a master quer y only if the quer y
contains the same address as that in the parameter 126 Slave address
The permitted addresses range from 1 to 254 and there must not be controllers
with the same address on the same line.

Data logger: flag end of memor y. 0 indicates that
memory is still available. 1 indicates memory is saturated
and device restarted to store data from address

.

Address 255 can be used by the master to communicate with all the connected
equipme nt (broadcast mod e), while wit h 0 all the devices receive t he command,
but no response is expected.
DP400S can introduce a delay (in milliseconds) in response to the master
request. This delay must be set on parameter 129 Serial Delay
