Error state
This parameter allows you to define the response of the digital in- and
outputs following a fault of the SIWAREX module
The following values can be set:
– All „FALSE“ – All outputs are switched off
– Obtain functionality
– Defined value -- The relevant substitute value is activated
– All „TRUE“ -- Outputs are switched on
1.5.2 Analogue output
SIWAREX WT241 is providing one analogue output which is parameterized
in menu 1.5.2.
Range
This parameter is used to define the output current range.
The following values can be set:
– 0 … 20 mA
– 4 … 20 mA
Source
The analog output can be used for a range of purposes. This parameter
defines the tag that controls the analog output.
The following values can be set:
– Belt speed
– Belt load
– Flow rate
– Test / force output
Start value (0/4mA)
This parameter defines the specified value at which 0 or 4 mA is output.
The value can be greater or less than the end value.
End value (20mA)
This parameter defines the specified value at which 20 mA is output.
The value can be greater or less than the start value.
State by error or
stop
This parameter defines the response of the analog output following a
fault of the SIWAREX module.
The following values can be set:
– Min. (0mA)
– Obtain functionality
– Defined value
– Max. (24mA)
1.5.3 Remote totalizer pulse signal
By parameterizing the corresponding digital output you can use one of the
digital outputs as a pulse sensor/quantity (see 8.7 “Menu 1.5 Communica-
tion & interfaces” 68).
In addition you must specify a load per pulse and a pulse duration for the
signal. If the material flow rate is displayed e.g. in t/h, you must specify the
quantity per pulse in t, or with kg/h in kg. The pulse duration is defined in
ms.
Make sure when setting the parameters that you only enter plausible com-
