ROPEX CAN
Version 1 RES-5009 Page 83
Each measurement pause command is answered with an acknowledgement message (CAN message
address 0009). The acknowledgement message contains the lower 6 bits of the controller status and the last tem-
perature measured before the measurement pause.
11.5.4 Alloy/range (heating band alloy TCR/temperature range)
With CAN message address 0008, the RESISTRON
®
Temperature Controller RES-5009 can be configured for
different heating band alloys and temperature ranges (T
max
). The set heating band alloy and the set temperature
range are permanently stored in the controller and will be retained even after a power failure. The current setting
can be read back via CAN message address 11. The controller is delivered with setting 1, i. e. TCR = 1100 ppm
and temperature range = 300 °C.
If “variable” is selected (value 11) under alloy/range (CAN message address 0008),
• the temperature coefficient TCR of the heating element material can be set via CAN message address 000A
• the temperature range can be set via CAN message address 0014
h
and
• the maximum permissible setpoint T
max
can be set via CAN message address 0013
h
.
If a setpoint is specified that is greater than the maximum permitted temperature T
max
, it will be limited to the max-
imum value.
The scaling of the analogue output for the ACTUAL temperature depends on the selected temperature range:
CAUTION
After changing the alloy/range, the AUTOCAL function must be executed.
11.5.5 Querying ACTUAL temperature
The RESISTRON
®
Temperature Controller RES-5009 responds to the command for querying the actual value
with the value of the current ACTUAL temperature in °C. Negative temperatures are marked by the “prefix” bit
(most significant bit).
