136 135 Device status mode
Range:
0 = Control mode
1 = Control mode with error E.130
2 = Control mode with error E.140
3 = Burn-off procedure in progress
4 = Purge procedure in progress
5 = Probe test procedure in progress
6 = Configuration mode
7 = Security code mode
Note:
For E.130/E.140 errors, see Technical
specifications Eng. 247E
The error is reset when read if device is in
remote state

137 136 Type of operative set point
Range:
0 = The set point utilized is a value set by
serial link (“Operative Set Point
Value”)
1 = Main set point
2 = Auxiliary set point 2
3 = Auxiliary set point 3
4 = Auxiliary set point 4
N.A. x
138 137 Operative set point value
Note:
It is utilized by the device for the PID as
well as for the SMART algorithms.
Any change will not be influenced by the
gradient mechanism. This set point value
is not going to be stored in Earom and it
will be lost at power down.
