Checking the Sequence
Functions
!
The following parameters can be checked at the display menu
while the
sequence
is running, or when it has been suspended:
>
Pout
= max. output power
>
U_
= min. output voltage
>
U
= max. output voltage
>
I
_
= min. output current
>
I
= max. output current
>
rcl
= address of the current memory location
>
rrEP
= number of repetitions yet to be executed
>
USEt
= momentary output voltage
>
ISEt
= momentary output current
>
tSEt
= execution time for the current address
(
tSEt
or
tdEF
), no display of remaining time
>
SSEt
= output level for
SSEt
switching function
Checking the Sequence with Manual Operation
☞
Press the <
SELECT
> key and browse through the display
menu.
☞
Further information is included in chapter 4.8.
Checking the Sequence with Remote Querying
The status of the sequence can be queried by means of remote
command (see page 70).
Possible responses to text: “RUN”, “HOLD”, “RDY”
RUN: active sequence
HOLD: sequence suspended
RDY: device in initial state
Numeric value for number of repetitions yet to be executed (rrep)
Numeric value for current memory address (rcl)
Influencing Step-by-Step Control
Step-by-step control is used to test Uset, Iset and Sset setpoint
values in a time-independent fashion before a sequence is run
automatically. Step-by-step control is activated by executing the
sequence
START command, or by initial execution of the
sequence
STEP command.
Executing the Start Address and Beginning Step-by-Step Control
(status: HOLD
HOLD, or RUN
HOLD)
Functions
!
The start address can be selected at any time from a
suspended or a running
sequence
. The setpoints saved to the start
address are executed. The selected dwell time of the exited and the
new memory address is not taken into consideration.
!
The device is switched from automatic sequence to step-by-
step control the first time this step is executed.
•
The output is switched to the output on status.
Procedure:
☞
With
interrupted
or
running
sequence,
– press the <FUNCTION> key and then browse with the
<
> key, the <
> or the <FUNCTION> key
until SEq
start
appears,
and execute the command with the
<ENTER>
key.
!
The
SEQUENCE
executes the start address.
!
If the sequence is in the HOLD status, the selected dwell time
is irrelevant.
!
The LOCKED/SEQ LED blinks slowly in the HOLD status
.
Execute Next Address (status: HOLD
HOLD)
Functions
!
The next or the previous memory location can be selected at
any time from a suspended
sequence
– in the step-by-step
control mode. The setpoints saved to the next or the previous
memory location are executed. The selected dwell time of the
exited and the new memory address is not taken into
consideration.
•
The output retains its switching status (output On or Off).
•
When jumping from the stop address to the start address or
back again, the remaining repetitions counter (rrep) remains
unchanged.
Procedure:
☞
With
suspended
sequence,
– press the <
ENTER
> key (next address) or
– the <
> key (next address)
the <
> key (previous address) or
– press the <FUNCTION> key and then browse with the
<
> key, the <
> or the <FUNCTION> key
until SEq
step
appears
and execute the command (next address) with the
<ENTER>
key.
!
The
sequence
executes the next or the previous address.
!
If the sequence is in the HOLD status, the selected dwell time
is irrelevant.
!
The LOCKED/SEQ LED blinks slowly in the HOLD status
.
•
Start automatic sequence run from the current memory
location: see resuming the sequence from the HOLD status in
the following chapter.
•
Start automatic sequence run: see sequence restart in the
following chapter.
•
Jump to the stop address: see ending the sequence at the stop
address in the following chapter.
•
End step-by-step control at the current address: see ending the
sequence at the current address in the following chapter.
Influencing the Automatic Sequence Run
Stop Sequence Manually – End at Stop Address
(status: RUN
RDY)
Functions
!
A
SEQUENCE
can be stopped (ready status) at any time while it
is running (run status), or when it has been suspended (hold
status).
!
The sequence jumps to the stop address when interrupted.
•
If the memory location assigned to the stop address is empty,
the Uset, Iset and Sset values from the last executed address
are retained. If the memory location assigned to the stop
address is not empty, Uset and Iset are changed to the
corresponding values. Selected dwell time Tset of the of the
last executed memory location is not taken into consideration.
!
The output retains its switching status (output On or Off) if the
memory location assigned to the stop address is not empty.
The output is switched to the off status if the memory location
assigned to the stop address is empty.
Procedure:
☞
Press the <
FUNCTION
> key.
!
SEq
StoP
blinks at the display.
☞
Press the <
ENTER
> key.
!
The contents of the stop address are executed. The sequence
is ended.
