9 Digital display
9.1 Standard display
According to the particular type, the following 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 Pt 100 sensor)
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 Pt 100 sensor)
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 Pt 100 sensor 2)
The displayed value corresponds to the highest value which has been measured since
the supply voltage was switched on or since the last reset.
•
S.P.1 (switch point 1) or S.P.2 (switch point 2) (for HDA 5500-3-1-XC-000) or
S.P.1 (switch point 1), S.P.2 (switch point 2), S.P.3 (switch point 3) or S.P.4 (switch point
4) (for HDA 5500-3-2-XC-000)
The displayed value corresponds to the particular pre-set switch point.
Important:
•
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
or
keys the
following values can be displayed separately. These values are each displayed for approxi-
mately 3 s:
•
Lowest value
•
Peak value
•
Switch point(s)
•
Sensor 1 or 2 (Pt 100 sensor)
The relevant lowest and peak values are reset by pressing the
and
keys simultane-
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.
