a visual indication of the following:
1.
Total operating time of the force feed lube system in hours.
2.
"Average", "Last" and "Current" cycle time of the divider block in seconds.
3.
Total divider block cycles.
4.
Remaining battery power life in percent.
5.
Alarm set time for no-flow indication (programmable 30 to 240 seconds).
6.
Alarm wiring mode: Normally Open or Normally Closed.
Proflo PF1 Monitor wiring identification and instructions for
electronic indication:
NOTE: IF THE PULSE OUTPUT (BLUE WIRES) AND ALARM CIRCUIT (RED WIRES)
ARE TO BE USED AT THE SAME TIME, PLEASE REFER TO “Proflo PF1 -
Using Pulse Output and Alarm Circuit at Same Time:” on page 4-47.
Blue Wires:
Pulse output.
The two (2) blue wires can be used to send a transistor pulse output for each
divider block cycle to a PLC (Programmable Logic Controller), Scada System, Digital Counter
or Digital Control Panel. Maximum switching load is 36 Vdc @ 500mA.
Insulate blue wire
ends from each other and conduit or compressor ground when not in use.
Pulse dura-
tion is 500 milliseconds. Switch output operation: Pulse represents 1 divider block cycle or
period.
White Wires:
Switch input. Remote mounting Proflo PF1 display.
The two (2) white wires can be con-
nected to a dry contact proximity switch. This allows remote mounting of the monitor box
housing in a convenient location on the compressor frame or in the control panel. Ariel rec-
ommends distance between proximity switch and the panel mounted Proflo should not ex-
ceed 600 feet (183 m). Please refer to Proflo PF1 operating notes for more information.
Insulate white wire ends, from each other and from ground, when not in use.
For panel
mount kit, see “Proflo PF1 Accessories Available:” on page 4-49.
Red Wires:
Alarm switch output.
The two (2) red wires are for a no-flow alarm contact. This can be used
for alarm or shutdown no-flow indication at a control panel. When the divider block cycles this
contact closes when in Normally Closed (NC) operation and opens when in Normally Open
(NO) operation. The contact returns to static state when the preset timer times out. Switching
Capacity: 36 Vdc @ 500 mA max.
Insulate red wire ends from each other and from
ground when not in use.
This output operation is programmable as NO or NC. Ariel recom-
mends using a NC system for fail-safe operation. Red wires are not polarity sensitive. See
“Proflo Normally Open and Normally Closed Definition:” on page 4-46.
Green Wire:
The green wire must be securely grounded to an "earth ground" on the compressor frame or
in the control panel. Do not ground to the electrical conduit. Improper grounding can result in
unreliable operation of the monitor.
