4.7.2
AnIF – “Analog Interface” Function Group
The analog interface allows for remote control of the
KONSTANTER.
An isolated digital control input (
TRG IN+ / TRG IN-
) and digital signal
outputs (
SIG1 / SIG2
) are available in addition to analog setting
options.
Other devices can be controlled in this way (e.g. counters, alarms,
SSP KONSTANTERs and many more). A
master-slave
system can
be set up in combination with a second or several
SSP KONSTANTERs (see also chapter 5).
Observe specified
maximum current and voltage values
for signal
outputs.
trG – Function Selection for Trigger Input
Functions
•
Floating
optocoupler input (
TRG IN
) at the analog interface
•
The trigger input is controlled with a digital signal
(low: 0 V, high: 4 ... 26 V).
•
Response time is approximately 1 to 15 ms.
Setting Parameter
☞
OFF:
Trigger input function is deactivated, signals at the trigger
input are ignored.
☞
OUT:
Trigger input influences the
OUTPUT
: output on / off
☞
RCL
: Memory recall from defined start to defined stop address
(step-by-step sequence control)
☞
SEQ:
Controlling Execution of the SEQUENCE Function
SEQUENCE
: Sequential execution of specified values for Iset,
Uset and dwell time (see also chapter 4.7.3).
The SEQUENCE function group must be set to
SEQUENCE ON
for this function.
☞
LLO: (LOCAL LOCKED)
Operation via front panel controls is
disabled.
☞

MIN-MAX
function: Storage of Min-Max values for U and I is

TRIGGER Signal Influence on OUTPUT Status
LOW
Status depends upon manual setting or
programming command
LOW _
HIGH
OUTPUT remains OFF or
OUTPUT is switched OFF
HIGH
OUTPUT in the OFF state,
cannot be switched on – neither manually
nor with a programming command
HIGH
_ LOW
OUTPUT is activated,
except in the event of
OTP
or
OVP
TRIGGER Signal Influence on step-by-step control
Edge
Low
High
Start trigger signal
HIGH
The trigger signal is a high pulse with
a duration of 11 to 800 ms.
A high pulse with a duration > 1.0 s
resets the address counter to the start
address at any point in time, and
execution begins with the next trigger
signal.
Edge
High
Low
The high
low edge of the (short) trigger
signal results in step-by-step control of
the currently selected sequence,
regardless of the specified time and
number of repetitions.
Recall of the memory’s contents begins
with the START address. Each trigger
signal increasers the address by 1, until
the STOP address is reached. The next
pulse once again causes execution of the
contents of the START address.
TRIGGER Signal Influence on SEQUENCE Status
LOW _
HIGH
The SEQUENCE function is started beginning
with the start address,
SEQUENCE GO
HIGH
_ LOW
Ends sequence execution by jumping to
the stop address.
TRIGGER Signal Influence on Front Panel Controls
LOW
All front panel controls are functional.
HIGH
All front panel controls are disabled,
except for the mains switch,
no activation with the
LOCAL
key.
TRIGGER Signal Influence on Min-Max Status
LOW
The Min-Max function is active.
LOW _
HIGH
The Min-Max function is deactivated.
Levels in the in Min-Max memories
remain unchanged.
HIGH
The Min-Max function is inactive.
HIGH
_ LOW
Values in the Min-Max memories are
replaced with momentary output values.
The Min-Max function is activated.
