The instrument can signal an external alarm by activating the digital input with the function programmed as “diF” = 3 (see par. 4.7).
At the same time as the signalling of the alarm (buzzer and/or out- put), the instrument signals the alarm by turning on the led AL and visualising AL and the measured temperature alternately on the display.
4.7 - DIGITAL INPUT
The digital input present on the instrument accepts contacts free of voltage, the function carried out is defined by the parameter “diF”. The parameter “diF” can be configured for the following functions:
= 0 - Digital input not active
= 1 - defrosting commencement command with contact normally open: on closing the input a defrosting cycle is activated.
