therefore always be used (  section 5 "Accessories
and modifications" on page 6).
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 (
 section 10.16 "Error
messages" on page 45).
10.6 Hold mode
The ACTUAL temperature query via the CAN interface
(
 section 10.3.6 "Querying the ACTUAL temperature"
on page 33) can be set in CAN message address 9
(
 section 10.3 "Receiving CAN messages" on
page 27). 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.
3. "2 seconds"
The current ACTUAL temperature is transferred for
an additional 2 seconds at the end of a heating
phase if it is queried via the CAN interface. The
ACTUAL temperature is then transferred again in
real time until the end of the next heating phase.
Hold mode only applies to queries via the
CAN interface. The ACTUAL temperature
always appears in real time at the analog actual
value output.
