1. Functional Description
This setpoint generator is an easy-to-
use microprocessor-controlled device
outputting current and voltage values.
Current: 0 ... 24 mA
Voltage: 0 ... 12 V DC.
Only one output can be used at a
time.
Three operating modes can be pro-
grammed:
– Standard setpoint function
– Manual ramp function
– Automatic ramp operation
Data backup for power failure
The programmed data is saved in an
EEprom; it remains saved even in
case of a power breakdown.
1.1 The SEtP Operating Mode
In this mode, the device is operated
in manual operation after program-
ming: a setpoint is input by means of
the keys. The value input here
directly in volts or mA, will be the
value output by the device.
If no other key is depressed within 3
seconds, the value input will be con-
sidered as the new setpoint and will
be output by the device.
1.2 The MAn Operating Mode
In this mode, the device is operated
in manual ramp operation after
programming: this operation is defi-
ned by means of 2 freely selectable
current or voltage values and by the
increment. During operation, press
the right key to increase the setpoint
by the increment programmed, press
the left key to reduce the setpoint by
this increment. In addition, the
device offers the possibility to apply
a scale factor to the setpoint output:
it is possible to display e.g. 10 (kg)
while 2 V are output. During operati-
on, the display alternates between
the output setpoint and the message
MAn.
1.3 The Auto Operating Mode
In this mode, the device is operated
in ramp operation after program-
ming: the automatic ramp function is
defined by means of a maximum of
20 current or voltage values which
are output automatically. The ramp
function can be either cyclic or
limited. A cycle can be programmed
in the range of 0.1 s ... 999.9 s or
0.1 min .... 999.9 min. The automatic
ramp function is started with the
right key. It can be ended with the
left key. The automatic ramp function
can be stopped by activating the
Hold input. During operation, the dis-
play alternates between the output
setpoint and the message Auto.

2 Safety Instructions and Warnings
1. Before carrying out any installation
or maintenance work, make sure
that the power supply of the digital
display is switched off.
2. Only operate this device accor-
ding to its intended purpose.
3. It must be in perfect technical
condition.
4. Use this device in accordance
with the instructions of the opera-
ting manual and the general
safety notes.
5. Take into consideration the provi-
sions specific to the country of use
and to the user.
6. This device is not suitable for
areas subject to explosion
hazards, nor for the operating
areas excluded in standard
EN 61010 Section 1.
7. The digital display can only be
operated as a properly built-in
device, according to the chapter
“general technical data”.

4www.kep.com
This device shall only be operated
as a built-in device. Its fields of appli-
cation are industrial processes and
controls for manufacturing lines in
the metal, wood, plastic, paper, glass
and textile industry, and similar appli-
cations.
Overvoltages at the screw terminals
of the device must be limited at the
values of the overvoltage category II.
If the device is used for monitoring
machines or process flows, in which
a breakdown of the device or an
operating mistake might lead to
machine damages or operator acci-
dents, the user must take suitable
safety measures.
2.1 Intended Purpose
3 Start-up
After powering the device, the following
message is displayed for 2 seconds:
Then the device type is displayed for
2 seconds, followed by the software
version, also for 2 seconds. After
reading the EEPROM, the device
switches to the operating mode.
3.1. Reset, Back to Factory Setting
Press both keys simultaneously and
power the device: the following mes-
sage appears on the display:
The device is reset to the factory
settings and is now ready for opera-
tion.
3.2. Programming and Operation of
the Setpoint Generator With the
2 Keys
While programming, press both keys
simultaneously to switch over to the
following parameter.
Within a parameter, confirm an input
also by pressing both keys.

Note When this manual instructs
to press both keys simulta-
neously, press the left key
slightly before the right key;
hold both keys pressed for
at least 3 seconds.
To call the programming mode:
⇑⇑
1. Press simultaneously both front
side keys.

ween YES and No
4. If YES is displayed and both keys
are pressed, the programming mode
is called for. no exits the program-
ming mode

6. If, during operation, the operator
switches to the programming mode
and alters the parameters ou.Lo.
or ou.Hi, take into account the fol-
lowing when exiting the program-
ming mode:
If the value of parameter ou.Lo
was altered, the output of the devi-
ce will automatically be set to the
value of parameter ou.Lo when it
will be set back to operation.
If the value of parameter ou.Hi
was altered, the output of the devi-
ce will automatically be set to the
value of parameter ou.Lo when it
will be set back to operation.
– SiGnal allows selecting
the setpoint output in volts or mA.
Press both keys to switch over from
SiGn to ou.Lo and ou.HI.
– output.Low allows defi-
ning the lowest value.
– output.High allows defi-
ning the highest value.
Use the left key to select the decade
and the right key to select a value
from 0 ... 9.
During operation, it is not possible to
define a value lower than the ou.Lo
value or higher than the ou.Hi value.
The default value for ou.Lo is 0 V or
0 mA. The default value for ou.Hi is
12 V or 24 mA.

the setpoint output in volts or mA.
Press both keys to switch over from
SiGn to ou.Lo and ou.HI.
– output.Low allows defin-
ing the lowest value.
– output.High allows
defining the highest value.
– StEP allows defining
the increment. During operation,
the setpoint output will increase by
this value when the right key is
pressed. The setpoint output will
decrease by this value when the
left key is pressed. During opera-
tion, if the operator tries to reduce
the setpoint below the low limit, the
setpoint will be maintained at the
value of ou.Lo.
If he tries to exceed the upper
limit, the setpoint will be main-
tained at the value of ou.Hi.
Note
If, during operation, the operator
switches to the programming mode
and alters the value of ou.Lo, ou.Hi,
di.Lo or di.Hi, the parameter StEP
will be reset to zero and the output
value will be reset to ou.Lo or di.Lo.

– The function
SPecial.decimalPoint allows defi-
ning the number of decimal places
(only for the values appearing on
the display).
– display.Low allows
defining the minimum value to be
displayed. This value corresponds
to the value ou.Lo used for the
output setpoint.
