If the system is in Prime mode, the following will occur:
•
Output 9 will be energized (lubrication on)
•
Output 10 will output a 120 cycle per minute pulse train to rapidly cycle the piston pumps
•
The Blue LED indicator on the control panel door will strobe in sync with Output 10
•
The Red LED indicator on the PRIME pushbutton located on the PCB will be illuminated, indicating that the
system is in Prime mode
•
HVPS will be disabled
•
Nozzle 1 & 2 Pressure Low and Pressure High inputs will be disabled
To exit Prime mode, one
of the following must occur:
•
The system is put into Lubrication Mode (Input 3 is energized). This automatically terminates Prime mode
•
Press the Reset button on the control panel door
•
Press the Prime pushbutton located on the printed circuit board
•
Momentarily energize Input 1 (Customer Prime mode input)
•
The Prime mode cycle timer expires (60 minutes)
•
A fault condition (Low air pressure or Low reservoir level)
