which is recommended in the case of turbulent measurements (e.g. water temperature in a boiler)
(2) – applies to analog inputs ( mA, V, mV, Ω )
(3) – a non-significant parameter for AR500, AR503, and AR518 (as the display is a single-color one)
11. QUICK ACCESS MENU
In the measurement mode (when the measured value is displayed), it is possible to immediately access certain
parameters without the need to enter a password. This possibility is offered by the quick menu, which can be
accessed by pressing the [SET] button. The parameter is selected and edited in the same way as described above
(in chapter 10).
Table 11. List of elements accessible in the quick configuration menu.
SEt1
preset alarm value (parameter 6: SEt1 ), optional element - unavailable when parameter 5: out1 = oFF
HSEt
preset value of the manual mode (12: HSEt ), optional element - available in the manual operation mode
12. ANALOG OUTPUT AND ALARM CONFIGURATION
The programmable architecture of the meter enables using it in many fields and applications. Before the operation
of the device starts, it is necessary to set the parameters according to specific requirements (chapter 10).
A detailed description of configuration of the operation of the analog output and the alarm is given in chapters
12.1÷ 12.3. The alarm can be signaled both through the analog output (not available in the AR500) and through
variable color of the display (parameter
18: AcoL
only in the AR517). The default (factory) configuration
is the following: the analog output and the alarm are switched off (Table 10, Factory settings column).
12.1. CHANGING THE PRESET VALUE FOR THE ALARM AND THE MANUAL MODE
In the measurement mode, the display shows the value being measured. The simplest way to change the preset
value for the alarm or the manual mode (parameter 6: SEt1 or 12: HSEt when the analog output is in the manual
mode) is to use the [UP] button or the [DOWN] button. As an alternative, it is possible to change the preset value
in the parameter configuration mode (using the methods described in chapter 10).
12.2. ANALOG OUTPUT
The standard of the output signal is determined by parameter 8: AtYP (chapter 10, table 10). The analog output
can work in one of the following modes: retransmission of measurement (parameter 9: outA = rEtr ), manual
mode (9: outA = hAnd ) and as an alarm/control output (9: outA = ALAr ).
In the measurement retransmission mode, the output signal is proportional to the measured signal in the range
set by parameters 10: A-Lo and 11: A-Hi (e.g. 0 mA for the measured value 0
°C when
A-Lo
= 0 °C
, 20 mA for 100
°C
when
A-Hi
= 100 °C and, as appropriate, 10 mA for the half of the range, i.e. 50 °C)
.
Manual operation (chapter 12.3) makes it possible to change the output signal in the range of 0 ÷ 100%
with a 1% step.
In the alarm/control output mode, the alarm/control parameters are mandatory
(the following apply: 5: ovt1 , 6: SEt1 , 7: H1 ). In the alarm/control mode, the range of variability of the analog
signal is not continuous and the output assumes limit values (lower or upper, e.g. 0 mA or 20 mA), without
intermediate values. The analog output is not available in the AR500.
12.3. MANUAL AND REMOTE CONTROL FUNCTION
The manual mode enables setting the value of the output signal in the entire range of its variability (0-100%), thus
enabling operation in an open regulation loop (no automatic coupling between the measured value and the
