Note 2. Function 3 & 4 Pretrip Timer
Continued.
When a user selects a value for P06, it must be in increments of 1.0 ms. In addition
to this there is a negative offset of 1.0 ms. Also observe in Table 4 that the Function 3
pretrip timer (F3) is represented by the lower four bits of P06, and the Function 4
pretrip timer (F4) is represented by the upper four bits of P06. Therefore when you set
P06 equal to a number, you are setting F3 and F4 simultaneously. Also note that the
minimum setting of F3 and F4 is 2, for security reasons. For example, if a user wants
F4 to be = 12 ms , and F3 to be = 10 ms, do the following:
For F4 (upper four bits): (12 ms) - 1 = 11 (decimal) = 1011 (binary)
For F3 (lower four bits): (10 ms) - 1 = 9 (decimal) = 1001 (binary)
The 11 and 9 can be entered in either decimal or binary format. Thus enter the
following SCL command:
<address>:<subaddress>:SET:P06=185;
or
<address>:<subaddress>:SET:P06=B10111001;
NOTE
On 2 Function Systems, Function 3 and 4, pre-trip timers must be set to 3ms.
Note 3 . Tx Time Slot
The value entered for P11 shall be 32 - the desired Tx time slot. For example, if the
user wants the Tx time slot to be = 27, then P11 shall be set = 5. This can be
entered in either decimal or binary format as shown in the following SCL command:
(Note that for E1 systems, actual time slot 1 cannot be used for payload. The first
usage time slot is considered time slot 2 for the purposes of setting P11 and P13)
<address>:<subaddress>:SET:P11=5;
or
<address>:<subaddress>:SET:P11=B00000101;
