Channel selection (CH0…CH2)
The RESISTRON
®
Temperature Controller RES-5009 has separate memories for up to eight calibration data sets.
A calibration data set contains the values that the temperature controller determines during the AUTOCAL func-
tion. Saving of the calibration data sets allows to operate welding tools in alternation without having to perform the
AUTOCAL function after each change. AUTOCAL has to be performed only when connecting a new heating ele-
ment.
As different calibration values, Autocal temperatures and temperature coefficients are available for this in the con-
troller, the desired calibration data set 0…7 can be selected over the 3 bits CH0…CH2. The channel can be
switched at any time.
This function can be used, for example, in applications that require frequent change of the format. In such a case,
different tools can be replaced for the different formats. A channel that contains the corresponding calibration data
set can be assigned to each tool. When all tools have been calibrated with a uniquely assigned channel, the fol-
lowing changes can be performed by just selecting the corresponding channel again.
For applications that do not require a format change, the channel can stay at 0. As a result, the temperature con-
troller acts exactly like older models that do not yet support any different calibration data sets.
While the channel can be switched during performance of the AUTOCAL function, the controller works with the
channel chosen at the start of the AUTOCAL function until the AUTOCAL function is completed. The channel cur-
rently used by the controller is visible in the status information.
The selected channel is not stored retentively in the temperature controller. After restarting the device, the desired
channel must be set again. Channel 0 is active by default.
9.2.6
Setpoint
Depending on the selected temperature range (
section 9.4.1 "Temperature range and alloy" on page 37), the
setpoint can be specified up to 300 °C or up to 500 °C. In case of larger setpoints, write access (CANopen) is
rejected, or the internal limit is set to 300 °C or 500 °C (ROPEX-CAN).
9.2.7
24 VDC control signal
The activation of a START/STOP command for setpoints 0 and 1 can also be carried out via a digital 24 VDC con-
trol signal (START 0 or START 1). With activation of a START” signal, the device-internal target-actual compar-
ison is enabled and the heating element is heated up to the set SETPOINT temperature. This takes place until the
signal is switched off.
The “HEAT” LED on the front panel of the RESISTRON
®
Temperature Controller RES-5009 lights up permanently
during this time.
The “START” signal (START 0) for setpoint 0 is activated via a 24 VDC signal at terminals 16+7.
