Controller functions
Page 38 RES-409 Version 1
If a contactor Kb is used to deactivate the control loop (  section 8.3 "Power supply" on page 17 ) ,
it must be reliably energized again 200ms at the latest after the "RESET" command is received (note
the contactor switching and delay times). If it is energized too late, an error message will be output by the
controller.
10.3.6 Querying the ACTUAL temperature
If the RES-409 receives a command requesting the actual value, it returns the current ACTUAL temperature in °C.
Negative temperatures are identified by the "sign" bit (most significant bit).
10.4 Sending CAN messages
The send command set of the RES-409 is shown in the table below:
