Notes about logic inputs used for program selection
1) When some logic inputs are programmed as program
selectors ("Pr.SL") the instrument will use these logic inputs
as a binary code.
In the sequence from DIG 1 to 3 and IN 1 to IN 8 the
instrument will considers the first logic input, programmed as
program selector, as the less significant bit while it will
consider the other inputs with increasing order.
For example:
DIG 2, DIG 3, IN 3, IN 7 and IN 8 are programmed as
program selectors. The DIG 2 is the less significant bit while
IN 8 in the most significant bit.
The weight of these 5 inputs is the following:
IN 8 IN 7 IN 3 DIG 3 DIG 2
2 4 2 3 2 2 2 1 2 0
16 8 4 2 1
2) If the program number 0 or a program number higher than 99
(90 simple programs + 9 linked programs) is selected, the
instrument will ignore the program selection made by logic
inputs and it allows to make the program selection by
keyboard or by serial link.
3) If a not existing program (a program from 1 to 99) is selected by
logic inputs, the instrument will use the selection made by logic
input and it will inhibit the selection made by keyboard or serial
link but the RUN request will not produce any effect.
4) A changement on the program selectors status has effect
only at the next RUN request.
Notes about logic inputs used for RUN/HOLD selection
At power up the instrument can start (see also "St.Fn" [C.G06]
and "St.Pr" [C.G07] parameters):
1) in manual mode
In this mode the RUN/HOLD logic input has no effect.
2) in stand-by mode
2.a) If "ru.SL" is selected, the RUN/HOLD logic input status
has no effect and the program will start when the
instrument detects the transition from the logic level 0 to
1 (from HOLD to RUN)
2.b) If "ru.St" is selected, the program will start when the
instrument detects the transition programmed by "d1.St"
[C.H02] parameter.
3) in RUN mode
3.a) If "ru.SL" is selected, the RUN/HOLD logic input status
defines the instrument status (logic level 0 for HOLD and
logic level 1 for RUN)
3.b) If "ru.St" is selected, the program starts in the same way
it was left prior to power shut down (HOLD or RUN).
NOTE: When the transfert from controller to programmer mode
is performed, the instrument starts in stand by status.
