Only the 300°C and 500°C temperature ranges appear at this actual value output. If a temperature range of 200°C
is set with CAN message address 8 ("Alloy/range"), it appears at this output in the 0…300°C range. A 400°C
temperature range is indicated as 0…500°C.
An indicating instrument can be connected to the 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 (
modifications" on page 9).
The meter not only facilitates SET-ACTUAL comparisons but also enables other criteria such as the heating rate,
set point reached within the specified time, heatsealing band cooling etc. to be evaluated.
This instrument additionally permits disturbances in the control loop (loose connections, contacting or wiring
problems) as well as any line disturbances to be efficiently monitored and accurately interpreted. The same applies
if mutual interference occurs between several neighboring control loops.
This output is not potential-free and can carry the secondary voltage of the impulse transformer.
External grounding is not allowed. If this warning is ignored, the controller will be damaged by frame
currents. Shock protection must be provided.
If a fault occurs, this analog output is used to display selective error messages (

Hold mode
The ACTUAL temperature query via the CAN interface (
section 10.3.6 "Querying the ACTUAL temperature" on
page 38) can be set in CAN message address 9 (
section 10.3 "Receiving CAN messages" on page 32). The
following settings are possible:
1.
"OFF" (factory setting)
The currently measured ACTUAL temperature is transferred via the CAN interface when the ACTUAL
temperature is queried.
2.
"ON"
The ACTUAL temperature at the end of the last heating phase is transferred when the ACTUAL temperature
is queried. When the controller is powered up, the real ACTUAL temperature is initially transferred until the end
of the first heating phase.
