8.5 Alarm parameters

The following parameters determine the behaviour of the outputs when
an alarm is active.
8.5.1 Status of the control outputs with probe alarm
(parameter c10)
This determines the action on the control outputs when there is a control
probe alarm E01, which may be one of the four responses envisaged.
When OFF is selected, the controller shuts down immediately and the
timers are ignored. When ON is selected, on the other hand, the "Delay
between activations of two diff erent relay outputs" (parameter c6) is
observed. When alarm E01 is resolved, the controller restarts normally
and the alarm output, if set, terminates the signal (see mode 5). On the
other hand, both the signal on display and the buzzer remain active until
Prg/mute is pressed.
