Functions -> Overview –> Analogue output tab
The figure below shows the window that appears when the Analogue Output tab is selected under
Function->Overview.
On this tab it is possible to define the operation of the analogue output i.e. the
measurement on the beam pattern that is going to be performed. The tab contains a number of marked areas; Analogue Output, Analogue Output Function and Set Analogue output.
Analogue Output
: In this box it is possible to
Enable Output
and
Disable Output
. When the output is enabled it is possible to select between
Current
output (4-20mA)* and
Voltage
output (0-10V)*
using the pull down box.
*Referred to 0 Vdc, pin 8 green wire (Analogue Out - )
Analogue Output Function
: The function of the analogue output depends on the setting of the control input on the receiver. If the
Digital Input 1
is connected to + (high), the function selected in the
pull down box next to
Control input high
is active. If the
Digital Input 1
is connected to – (i.e. low) or not connected (N.C.), the function selected in the pull down box next to
Control input low (NC
) will
be active. The functions selectable in the two boxes are identical. Notice that the status of the
Digital Input 1
can be read in the
Input and Output Status
field. Following function can be selected.
Analogue Output Moving Average:
The time constant defines how long the averaging is. The value can be from 0 to 2000 ms.
Measurement functions:
DIS: Disabled output.
Output is disabled, i.e. constantly de-energised.
FBB: First Beam Blocked.
Position of the first beam blocked.
FBM: First Beam Made.
Position of the first beam made.
LBB: Last Beam Blocked.
Position of the last beam blocked.
LBM: Last Beam Made.
Position of the last beam made.
MBB: Middle Beam Blocked.
Position of the (FBB+LBB)/2 rounded to nearest integer
TBB: Total Beams Blocked.
Total number of beams blocked.
TBM: Total Beams Made.
Total number of beams made.
CBB: Contiguous Beams Blocked.
Reads out the number of beams in the largest group of adjacent
beams blocked.
CBM: Contiguous Beams Made.
Reads out the number of beams in the largest group of adjacent
beams made.
TRN: Number of Transitions.
The number of transitions in the beam pattern between made beams and blocked beams.
OD: Outside dimensions.
Reads out LBB - FBB+1, corresponding to the size of a single object contained in the beam pattern, counted in beam breaks.
ID: Inside dimensions.
Reads out the count of beams made between first beam broken and last beam broken. This corresponds to the size of a hole in a single solid object in the light curtain.
CFBB: Contiguous First Beam Blocked.
Reads out the number of the first beam in the largest group of adjacent beams blocked.
CLBB: Contiguous Last Beam Blocked.
Reads out the number of the last beam in the largest group of adjacent beams blocked.
Force Set Enable
: Marking the checkbox
Force Set Enable
disables all measurements and enables the user to set the output value in the textbox next to
Analogue Output Value
.
This function can be used for test and calibration purposes.
SD: Speed and Direction.
Reads out the velocity of an object. The input box ‘minimum speed’ is used to define the velocity that corresponds to 4 mA/ 0 V. The input box ‘maximum speed’ is used to
define the velocity that corresponds to 20 mA / 10 V. Notice that both negative and positive values in the interval between -40 m/s and +40 m/s can be used. If objects are moving in direction of larger
beam numbers the beam number the velocity is positive. If the objects are moving in the direction of smaller beam numbers the velocity is negative.
Note:
The beams are counted starting with one from the end of the cable entry
.
Note:
Unintended use of pre-filtering, i.e. hole detection or Maximum Area of adjacent beams blocked set different from 0 can lead to unexpected results!
If crossed beam setting is used, the effective beam number is increase by a factor of 2.
