HDA 5500
9 Digital display
9.1 Standard display
According to the particular type, the following list of values can be set as the primary display.
The pre-set value concerned will be continuously displayed.
•
SEn.1 (measured value of sensor 1) or SEn.2 (measured value of frequency input)
The displayed value corresponds to the measured value and is proportional to the input
signal of the corresponding sensor. The values are linear between the lower limit and the
upper limit.
•
Min.1 (lowest value of sensor 1) or Min.2 (lowest value of frequency input)
The displayed value corresponds to the lowest value which has been measured since the
supply voltage was switched on or since the last reset.
•
ToP.1 (peak value of sensor 1) or ToP.2 (peak value of frequency input)
The displayed value corresponds to the highest value which has been measured since
the supply voltage was switched on or since the last reset.
Notes:
•
If the measured value exceeds the upper display range of the HDA 5500, then the
measured value can no longer be displayed. The upper display range flashes.
•
If the measured value is below 1 % of the lower display range, then the measured value
can no longer be displayed. The lower display range flashes.
9.2 Special display
If a measured value is set as the primary display, then by pressing the
following values can be displayed separately. These values are each displayed for approxi-
mately 3 s:
•
Lowest value
•
Peak value
•
Sensor 1 or 2 (frequency / counter function)
The relevant lowest and peak values are reset by pressing the
ously during normal operation. If the reset has been successful, rES (reset) is displayed to
confirm this.
10 Output response
The HDA 5500 has a through analogue output which is proportional to the input signal. In
addition, depending on the model and type, without switching outputs or two or four switching
outputs are available.
10.1 Analogue output
On the analogue output a 4..20 mA or 0..10 V signal is available. The signal is proportional to
the input signal of one of the sensors or of the differential value. Both the allocation of the
output signal to sensor or differential value and the type of signal can be adjusted during
normal operation.
For setting „diFF" (Analogue output allocated to differential value (sensor 1 – sensor 2))
reference for values of sensor 2 = values of sensor 1 is an analogue output signal of 12 mA
or accordingly 5 V. From there values of sensor 2 < values of sensor 1 are shown with
signals of 0 .. 12 mA or accordingly 0 .. 5 V and values of sensor 2 > values of sensor 1 are
shown with signals of 12 .. 20 mA or accordingly 5 .. 10 V.
