LUBRICATION MODE
Terminal Block J9
-
INPUT 3
-
Connection 5 & 6
Input 3 is the customer lubrication input. The input can be from a normally
-
open switch, normally
-
open relay contacts,
or from a PLC output. When the contacts are closed (24VDC is supplied to the input), the system will be in Lubrication
mode. When the contacts are open, the system will be in Standby mode.
Lubrication mode will override both
Test
and
Prime
modes.
If the Test mode cycle is not complete, and the lubrication
input is energized, the system will terminate Test mode and the system will enter Lubrication mode.
The system will
not
return to Test mode after the Lubrication mode is terminated.
If the system is in Lubrication mode, the following will occur:
•
Output 9 will be energized (lubrication on)
•
Output 10 will output a low frequency pulse train (adjustable by the PUMP ADJ potentiometer) to cycle the
piston pumps
•
The Blue LED indicator on the control panel door will strobe in sync with Output 10
•
HVPS will be enabled
To exit Lubrication Mode:
•
Standby mode:
Input 3 must be de
-
energized and SW5 –
Dip Switch 1 is an OFF position
•
Fault mode:
Any system fault occurs
•
System power:
OFF
ATTENTION: Burst will only be active while the system is in Lubrication mode (Input 3 energized).
BURST MODE
Terminal Block J9
-
INPUT 4
-
Connection 7 & 8 or PCB Mounted Pushbutton
When the BURST pushbutton and Input 4 are activated the system goes into burst mode.
Burst Mode Input
-
is used to increase the lubrication volume to 1.25x the current pump frequency setpoint for 24
hours (unless placed into a different mode). This allows for a 24
-
hour period of increased lubrication, when desired,
without the need to change the PMP ADJ potentiometer setting. Maximum burst mode frequency is 100 CPM.
When using the PCB Burst mode pushbutton, the red LED indicator will illuminate.
To exit Burst mode, one of the following must occur:
•
The Reset button on the control panel door is pressed
•
The BURST button on the PCB is pressed
•
The 24 hour mode timer expires (PCB Pushbutton)
4.8 OPTIONAL PCB INPUTS AND CONNECTIONS
Terminal Block J8
For factory use only.
Nozzle 1 & 2 Pressure Low & High
Terminal Block J9
-
INPUTS 5 through 8
-
Connection 9 through 16
Inputs 5 through 8 will activate when the nozzle pressure is inadequate. The system must be in Lubrication mode for 10
seconds before the inputs are enabled. It is intended to be used as nozzle pressure/flow input and allows the pressures
to stabilize before allowing a fault condition to occur.
