RES-407
If a ROPEX PD-x precision potentiometer is used, the
SET temperature can be adjusted exactly with the help
of the digital display in the window of the dial. The
number which appears on the display corresponds to
the SET temperature in °C.
The set point that is selected for the heatsealing
temperature must be greater than 40°C. If not, the
heatsealing band will not be heated up when the
"START" signal is activated.
If a potentiometer is not connected or if 0VDC
is applied to the set point input, the set point
is assumed to be zero. When you connect the
potentiometer, please note the direction of
rotation!

Temperature indication (actual
value output)
The RES-407 supplies an analog 0…10VDC signal,
which is proportional to the real ACTUAL temperature,
at terminals 17+14.
Voltage values:
0VDC
Æ
0°C
10VDC
Æ
300°C or 500°C
(depending on the contr. configuration)
The relationship between the change in the output
voltage and the ACTUAL temperature is linear.
An indicating instrument can be connected to this
output in order to visualize the temperature of the
heatsealing band.
The characteristics of the ROPEX ATR-x temperature
meter (size, scaling, dynamic response) are ideally
suited to this application and this instrument should
therefore always be used (
ª
and modifications" on page 6).
It not only facilitates SET-ACTUAL comparisons, but
also enables other criteria such as the heating rate, set
point reached within the specified time, cooling of the
heatsealing band etc. to be evaluated.
This meter moreover permits disturbances in the
control loop (loose connections, contacting or wiring
problems) as well as any line disturbances to be
