Step 1: Cancel the factory allocations of functions.
As the function tear-off detection requires only lines 21
and 22 of the bit block, the factory-side allocation of
functions to the remaining lines of the block (lines 23 to
28) must be cancelled.
Accordingly the function Do Nothing is allocated to lines
23 to 28 from the option list.
The procedure for doing this is described in example 1.
Moreover the values of all bits in the non-required lines
19 to 24 must be set to “1”.
Procedure:
1. Use the function keys F1 and F2 to sequentially
select the individual block lines.
2. Use the horizontal arrow keys to the change the bit
pattern (Bitmask) display.
3. Sequentially select the individual bits using the
horizontal arrow keys and use the vertical arrow
keys to set the value of the selected bit to “1”. The
values of all 12 bits must be set to "1”.
Step 2: Assign new function
The function Tear Out ON (tear-off detection ON) is
assigned to the line 21 and the function Tear Out OFF
(tear-off detection OFF) is assigned to the line 22.
The procedure for doing this is described in example 1.
Step 3: Adjust bit pattern
In line 21 the bit for terminal 84 is assigned the value ”1“
(24 V signal applied to terminal 84).
In line 22 the bit for terminal 84 is assigned the value ”0“
(0 V signal applied to terminal 84).
The value for all the non-relevant bits (terminal 83) of the
two lines 21 and 22 must be set to the value "X"
(not relevant).
The procedure for changing the bit values is described in
step 1.
