Teaching Analog Output Limits
The procedure for teaching analog output limits and discrete output limits is the same, except that the analog output has no hysteresis.
The analog output has one unique
function:
the discrete output limits Q1.1 and Q1.2 can be copied. To copy the discrete output limits
to the analog output, follow the steps below:
1.
Press
and
or
and
to scroll to TEACH-IN > <ANALOG>.
The sensor is ready to learn the analog output limits. The procedure is
identical
to the one for teaching discrete output limits, except
for the Copy and Paste
function.
2.
Press
or
to copy and paste Q to A. COPY Q->A > <ENTER> .
The sensor is ready to copy the discrete output limits to the analog output.
3.
Press
to view the
options.
4.
Press
and
to scroll between
options.
5.
Press
to select an
option.
• COPY Q->A > ->Q1 & Q2 .
• COPY Q->A > ->Q2 & Q1.
• <300 mm
The selected
option,
in
combination
with the selected mode, determines the analog output slope.
• For Mode 1
(positive
slope): Q1 & Q2 – Limit Q1.1 becomes A1 (4 mA); Q2.1 becomes A2 (20 mA) Q2 & Q1 – Limit Q1.1
becomes A2 (20 mA); Q2.1 becomes A1 (4 mA)
• For Mode 2
(negative
slope): The above is reversed. If discrete limits are not at least 300 mm apart, the display will show <
300 mm. The sensor will not perform the copy
function.
Accessing the
Offset
Menu
To access the OFFSET < 0 > menu, to save the current
offset
value
3
(sensing distance), or to adjust it, follow the steps below:
1.
Press
to access the
Offset
< 0 > menu. OFFSET 0 > OFFSET 426 or OFFSET 0 > OFFSET CLEAR? is displayed.
OFFSET 0 returns the sensor to the default
setting.
OFFSET 426 represents a programmed
offset
value with the current sensing
distance expressed in millimeters or one-hundredth of one inch. Select OFFSET CLEAR? when an
offset
value is displayed that needs
to be cleared before a new one can be programmed.
• To clear an
offset
value, go to Step 2.
• To save an
offset
value, go to Step 3.
• To adjust an
offset
value, go to Step 4.
2.
Press
to clear the
offset
value: OFFSET CLEARED!.
The
offset
value is cleared. The sensor returns to the Main menu.
3.
Press
to save the current
offset
value if it is correct.
4.
Press
and
to
activate
the
Offset
Value Adjustment
function:
OFFSET 0 > OFFSET 426.
The cursor
flashes
on the fourth digit from the
left.
5.
Press
to decrease or
to increase the value of each digit: OFFSET - 428 or 428.
Press
or
to change the minus symbol in front of the
first
digit to a plus symbol and vice versa.
6.
Press
to save the digit and to move the
flashing
cursor to the
left
by one digit
location.
The sensor saves each digit, including the + and - symbols.
7.
Press
when the cursor is on the
first
digit to the
left
and the value is correct. OFFSET < -428> or OFFSET < +428>.
The new
offset
value is saved. The sensor returns to the Main menu.
3 The selected
offset
value applies to all outputs.
