HDA 5500
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
•
Switch point(s) (depending on the model of HDA 5500)
•
Sensor 1, 2 or 3
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, the signal of which is proportional to an input
signal. In addition, depending on the model and type, the HDA 5500 is available either
without switching outputs, or with two or four switching outputs.
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.
