KS 4000 i 1011

• Each individual instruction including parameters and data as

well as each reply are terminated with CR LF (Code: hex
0x0D and 0x0A) and have a maximum lenght of 80 charac-
ters.

• The decimal separator in a floating point number is the point.

(Code: hex 0x2E)

The above statements largely correspond with the recommen-
dations of the NAMUR-Assocation (NAMUR-recommendati-
ons for the design of electric plug connections for the analog
and digital signal transmission to labortory - MSR individual
units. Rev. 1.1).

NAMUR instuctions Function

IN_NAME

Input description name

IN_PV_X

Reading the real value

X=1;2;3;4;

IN_SOFTWARE

Input software ID number
date, version

IN_SP_X

Reading the set rated value

X=1;2;3;4;6;12;

42;50;52;53;

IN_TYPE

Input laboratory unit ID

OUT_NAME name Output description name. (Max. 10 characters,

default: KS4000 ic)

OUT_SP_12@n

Setting the WD safety temperature with the
echo of the set value

OUT_SP_42@n

Setting the WD safety speed with the
echo of the set value

OUT_SP_X n

Setting the rated value to n

X=1;2;4;50;52

OUT_WD1@m

Watchdog mode 1: When a WD1 event occurs,
the heating and shaking functions are shutdown
and message PC 1 is displayed.
Set the watchdog time to m (20...1500) seconds,
with echo of the watchdog time. This instruction
starts the watchdog function and must be sent
within the set watchdog time.

OUT_WD2@m

Watchdog mode 2: When a WD2 event occurs,
the speed setpoint will be set to the WD safety
setpoint speed and the temperature setpoint
will be set to the WD safety setpoint temperatu-
re. The PC 2 warning is displayed.
The WD2 event can be reset with OUT_WD2@0-
resetting also blocks the watchdog function. Set
the watchdog time to m (20...1500) secondes,
with echo of the watchdog time. This command
starts the watchdog function and must be sent
within the set watchdog time.

RESET

Switching off the instrument function.
