11.2 Fascia Stop Pushbutton (Item 8)
The PF1 has a Stop pushbutton mounted on its fascia. Pressing the Stop pushbutton will open the K1
output relay, hence opening the outlet’s contactor.
The fascia Stop pushbutton can be used as an alternative to the “Stop” digital input.
NOTE
The Facia Stop button will only open the K1 output relay if the PF1 is
set to Pump Mode or Fan Mode. If the PF1 is not set to either Pump
Mode or Fan Mode, the
Fascia Stop button will not perform a
function
.
11.3 Digital Inputs (Reset, Start & Stop) (Item 9)
The PF1 has three digital inputs that perform pre-programmed functions when they are shorted to the
VDC terminal (for wiring details see Figure 4.4).
Reset Input
Closing the Reset input will clear any latched faults in the PF1, provided that fault conditions no longer
exist.
