Table 52: Settings – Alarms
The alarm function reports the falling below or exceeding of an adjustable temperature via the
associated object. Falling below the lower indication value is reported via the Frost alarm object.
Exceeding the upper indication value is reported via the heat alarm object. The two signalling
objects of size 1 bit can be used for visualisation or for initiating countermeasures. If the lower
indication value is exceeded again or the upper indication value is fallen short of again, a "0" is sent
in each case and thus the alarm is cancelled.
The following table shows the two objects:
Number Name/Function
Length Usage
22 Frost alarm – Send alarm 1 Bit Reports falling below the lower indication value
23 Heat alarm – Send alarm 1 Bit Reports the exceeding of the upper indication value
