9.3.12 Start temperature
The start temperature is the temperature measured directly before execution of a start request (ST bit = 1). This
measurement value can be used to evaluate the cooling. The value is valid only during the heating phase (ST
bit = 1). Outside of this phase, the value “-99 °C” is output, with which it can be differentiated whether or not the
value is valid. The value range lies between -20°C and 500°C.
9.3.13 Error numbers
If an alarm is present (AL bit = 1), the error number allows determination of the exact cause of the error.
(
 section 9.15 "Error messages" on page 49).
9.4 Parameter data
The parameter data contain values for
• the selection of the heating element alloy,
• the temperature range,
• the lower and upper tolerance band limits for temperature monitoring,
• the calibration temperature,
• the measurement impulse duration (only for special applications).
The parameter data can be transmitted at every system start from the CANopen/CAN master to the RESISTRON
®
Temperature Controller RES-5009. In addition, the parameters can be sent at any time via write/read accesses
from the CANopen/CAN master to the controller or queried by the controller.
The protocol-specific access as well as the storage of parameter data is explained for CANopen in chapter
 section 10.7.2 "Parameter data" on page 63 and for ROPEX-CAN in chapters and  section 11.5 "Receiving
CAN messages" on page 77 and section 11.6 "Sending CAN messages" on page 83.
9.4.1 Temperature range and alloy
With this parameter, both the temperature range and the heating element alloy can be selected. By changing the
standard value (10), the setting of the rotary coding switch (
 section 8.2.2 "Configuration of the rotary coding
switch for temperature range and alloy" on page 22) can be overwritten.
After a change of this parameter, the AUTOCAL function must be performed.
