Warnings
Programmed warning can activate any digital output relay 1-6 if selected.
Tprobe warning 1 to 8 can activate global fan NO relay.
Digital output contact icons are located at the bottom of the screen (Cf. Figure 52).These
icons are numbered 1 to 6 when they are disabled. If these output contacts are
programmed, the corresponding icon changes. When the PQF-Manager closes one of its
six digital output relays (Cf. Chapter 6) the corresponding symbol changes its
appearance as described in the Table 35. When the relay considered opens again, the
symbol takes back the original appearance.
If a digital output is ‘Disabled’ the default icon is shown.
