Precondition: Both controllers must be configured as pulse width or pulse
frequency controllers. The controller contacts must be configured as MIN/MIN or
MAX/MAX,
Chapter 26.5 "Controller outputs - C212", page 77.
Cause: With MIN/MIN there will be an error message if w1 > w2. There is no error
message if w1 < w2.
With MAX/MAX there will be an error message if w1 < w2. There is no error
message if w1 > w2.
This also applies to the second pair of setpoints, if setpoint changeover is
configured.
F060 Minimum ON time (tr1) is longer than the pulse period 1 (CY1) (only if controller 1 is
configured as a pulse width controller), or
Minimum ON time (tr1) is longer than 1/60 of the pulse frequency 1 (Fr1) (only if
controller 1 is configured as a pulse frequency controller), or
Chapter 20.1 "Settings", page 59ff.
F061 Minimum ON time 2 (tr2) is longer than the pulse period 2 (CY2) (only if controller 2
is configured as a pulse width controller), or
Minimum ON time (tr2) is longer than 1/60 of the pulse frequency 2 (Fr2) (only if
controller 2 is configured as a pulse frequency controller), or
Chapter 20.1 "Settings", page 59ff.
Err Calibration finished with an error. The old data are retained.
Cause:
The value determined during calibration lies outside the permissible range
Corrective action:

Errors F010 to F031 and "Err" trigger an alarm; the configured alarm output will switch
and the corresponding LED will blink.
With errors F022 to F024 and "Err", the controller additionally goes to the "HoLd"
condition,
The alarm relay does not switch as a result of one of the warnings F050 to F061, but the
corresponding LED will blink.
