Controller functions
RES-430 Page 35
Only the 300°C and 500°C temperature ranges appear
at this actual value output. If a temperature range of
200°C is set for the controller with step 205 in the
Configuration menu, 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 this
output in order to visualize the temperature of the
heatsealing band.
If an alarm is signaled, this analog output is used – in
addition to the value indicated on the controller – to
display a selective error message (
ª section 10.19
"Error messages" on page 42).
This output is not potential-free and could
have the potential of 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.
Contact voltage protection must be installed at the
terminals of the external temperature meter.
10.8 Automatic zero calibration
(AUTOCAL)
Owing to the automatic zero calibration (AUTOCAL)
function, there is no need to adjust the zero point
manually on the controller. The "AUTOCAL" function
matches the controller to the current and voltage
signals that are present in the system. You can activate
this function by selecting step 107 in the Settings menu
and then pressing the "ENTER" key. The initial
temperature (ambient temperature) of the heatsealing
bar(s) which is currently valid for calibration can be set
beforehand in the 0…40°C range using the "UP" and
"DOWN" keys.
The zero point is calibrated in the factory to 20°C.
The automatic calibration process takes around
10…15 seconds. The heatsealing band is not heated
until the calibration process has finished.
The message "- Calibration - Please wait..." appears
on the display while the "AUTOCAL" function is
executing and a counter counts down from 14 to 0. The
actual value output (terminals 10+11) is set to 0°C
(corresponds to 0 VDC) for the duration of the
calibration process.
You should always wait for the heatsealing
band and the bar to cool down (to ambient
temperature) before activating the "AUTOCAL"
function.
Reasons for locked AUTOCAL function:
1. The "AUTOCAL" function cannot be activated if the
heatsealing band cools down at a rate of more than
0.1K/second. This is additionally indicated with
step 107 in the Settings menu by the message
"Heatsealing band still hot! Please wait...".
2. If the "START" signal (HEAT) is activated, the
"AUTOCAL" function is not executed. This is
additionally indicated with step 107 in the Settings
menu by the message "Autocal locked! (START sig.
active)".
3. The AUTOCAL function cannot be activated if a fault
with error code 101…103, 201…203, 8xx or 9xx
occurs (
ª section 10.19 "Error messages" on
page 42).
