1. Functional Description
This setpoint generator is an easy-to-use micro-
processor-controlled device outputting current and
voltage values.
Current:
0 ... 24 mA
Voltage:
0 ... 12 V DC.
Either the current or the voltage output can be used.
1.1 The SEtP Operating Mode
In this mode, the device is operated in manual direct
input operation after programming: the value is
input here directly in volts or mA. If no other key is
depressed within 3 seconds, the value input will be
considered as the new setpoint and will be output by
the device. During operation, the display alternates
between the output setpoint and the message SEtP.
1.2 The MAn Operating Mode
In this mode, the device is operated in manual ramp
operation after programming: this operation is
defined by means of 2 freely selectable
current or voltage values and by the increment. Dur-
ing operation, press the right key to increase the set-
point by the increment programmed, press the left key
to reduce the setpoint accordingly. 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 operation, the dis-
play alternates between the output setpoint and the
message MAn.
1.3 The Auto Operating Mode
In this mode, the device is operated in automatic
ramp operation after programming. The automatic
ramp function is defined by means of a maximum of
20 current or voltage values which are output in a
synchronized way. The ramp function can be pro-
grammed either as a limited or as an endless loop.
Cycle time can be programmed in the range of 0.1 s
... 999.9 s or 0.1 min .... 999.9 min. The 1st cycle of
the automatic ramp function is started with the right
key. The ramp function can be ended with the left
key. The automatic ramp function can be stopped by
activating the Hold input. After deactivating the input,
it resumes operation at the point where it stopped.
During operation, the display alternates between the
output setpoint and the message Auto.

Three operating modes can be programmed:
– Manual direct input operation
– Manual ramp operation
– Automatic ramp operation
Data backup for power failure
The programmed data remains saved even in case of
a power breakdown.
