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 ROPEX ATR-x temperature meter is optimally adapted to this application in every respect (size, scale,
dynamic behavior) and can be used for this, if needed (
section 6 "Mounting and installation" on page 8).
The meter not only facilitates SET-ACTUAL comparisons but also enables other criteria such as the heating rate,
set point achieved within the specified time, cooling of the heatsealing band etc. to be evaluated.
The temperature meter additionally permits disturbances in the control loop (loose connections, contacting or
wiring problems) as well as any line disturbances to be observed extremely efficiently and interpreted accordingly.
The same applies if several neighbouring control loops interfere with one another.
If a fault is signalled, this analog output is used to display a selective error message (

Booster connection
The RES-5012 controller has a connection for an external switching amplifier (booster) as standard. This connec-
tion (at terminals 15+16) is necessary for high primary currents (continuous current > 5 A, pulsed current > 25 A).
The booster should be connected as described in section 6.7 "Wiring diagram with booster connection" on
page 15.
The connecting cable to the booster must not be longer than 1 m; it must also be twisted in order to
reduce EMC interference to a minimum.
