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.
Either the current or the voltage out-
put 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 con-

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

1.3 The Auto Operating Mode

In this mode, the device is operated
in automatuc 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 syn-
chronized way. The ramp function
can be programmed either as a limi-
ted or as an endless loop. Cycle
time can be programmed in the
range of 0.1 s ... 999.9 s or 0.1 min

Three operating modes can be pro-
grammed:
– Manual direct input operation
– Manual ramp operation
– Automatic ramp operation

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
display alternates between the out-
put setpoint and the message MAn.
.... 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 resu-
mes operation at the point where it
stopped. During operation, the dis-
play alternates between the output
setpoint and the message Auto.
