Controller functions
RES-407
Page 25
In addition to the functions shown in the diagram
above, various controller operating states are indicated
by the LEDs. These states are described in detail in the
table below:
10.2
Temperature setting
(set point selection)
The heatsealing temperature of the RES-407 can be
set in two ways:
• By applying a 0…10VDC voltage to the analog input
terminals 16 + 14:
The relationship between the applied voltage and the
SET temperature is linear.
Setting range:
0VDC
Æ
0°C
10VDC
Æ
300°C or 500°C
(depending on the contr. configuration)
Please refer to section 10.3 "Temperature indication
(actual value output)" on page 26 for a circuit diagram.
• By connecting a 2kohm potentiometer to
terminals 14…16:
In order to be able to select the set point with a
potentiometer, the controller makes a +10VDC (
±
5%
)
reference voltage available at terminal 15.
The relationship between the potentiometer setting and
the SET temperature is linear.
The connecting wires between the controller and the
potentiometer must be shielded.
