FOR MODELS: JGZ AND JGU SECTION 4 LUBRICATION<br />
a visual indication of the following:<br />
1. Total operating time of the force feed lube system in hours.<br />
2. "Average", "Last" and "Current" cycle time of the divider block in seconds.<br />
3. Total divider block cycles.<br />
4. Remaining battery power life in percent.<br />
5. Alarm set time for no-flow indication (programmable 30 to 240 seconds).<br />
6. Alarm wiring mode: Normally Open or Normally Closed.<br />
Proflo PF1 Monitor wiring identification and instructions for electronic<br />
indication:<br />
NOTE: IF THE PULSE OUTPUT (BLUE WIRES) AND ALARM CIRCUIT (RED WIRES)<br />
ARE TO BE USED AT THE SAME TIME, PLEASE REFER TO “Proflo PF1 - Using<br />
Pulse Output and Alarm Circuit at Same Time:” on page 4-45.<br />
Blue Wires:<br />
Pulse output. The two (2) blue wires can be used to send a transistor pulse output for each<br />
divider block cycle to a PLC (Programmable Logic Controller), Scada System, Digital Counter<br />
or Digital Control Panel. Maximum switching load is 36 Vdc @ 500mA. Insulate blue wire<br />
ends from each other and conduit or compressor ground when not in use. Pulse duration<br />
is 500 milliseconds. Switch output operation: Pulse represents 1 divider block cycle or period.<br />
White Wires:<br />
Switch input. Remote mounting Proflo PF1 display. The two (2) white wires can be connected<br />
to a dry contact proximity switch. This allows remote mounting of the monitor box housing<br />
in a convenient location on the compressor frame or in the control panel. <strong>Ariel</strong> recommends<br />
distance between proximity switch and the panel mounted Proflo should not exceed 600 feet<br />
(183 m). Please refer to Proflo PF1 operating notes for more information. Insulate white wire<br />
ends, from each other and from ground, when not in use. For panel mount kit, see “Proflo<br />
PF1 Accessories Available:” on page 4-47.<br />
Red Wires:<br />
Alarm switch output. The two (2) red wires are for a no-flow alarm contact. This can be used<br />
for alarm or shutdown no-flow indication at a control panel. When the divider block cycles this<br />
contact closes when in Normally Closed (NC) operation and opens when in Normally Open<br />
(NO) operation. The contact returns to static state when the preset timer times out. Switching<br />
Capacity: 36 Vdc @ 500 mA max. Insulate red wire ends from each other and from ground<br />
when not in use. This output operation is programmable as NO or NC. <strong>Ariel</strong> recommends using<br />
a NC system for fail-safe operation. Red wires are not polarity sensitive. See “Proflo Normally<br />
Open and Normally Closed Definition:” on page 4-44.<br />
Green Wire:<br />
The green wire must be securely grounded to an "earth ground" on the compressor frame or<br />
in the control panel. Do not ground to the electrical conduit. Improper grounding can result in<br />
unreliable operation of the monitor.<br />
