Important Safety Messages Healy equipment is designed to be installed in association with volatile hydrocarbon liquids. Installing or working on this equipment means working in an environment in which these highly flammable liquids may be present. Working in such a hazardous environment presents a risk of severe injury or death if these instructions and standard industry practices are not followed.

Description The Healy 6280 System Monitor continuously monitors the Vapor Recovery System performance. It is used with Healy central vacuum systems, and prints out a daily activity report. Operation There is no on-off switch – the power light is illuminated whenever power is supplied to the 6280 System Monitor.
Printing Reports Each day at midnight an automatic printout of the previous days’ activity will be printed. This will show all the previous data about run time and will show if any errors occurred that day. It does not show a history of errors. To get a history printout, press both RESET buttons on the front panel at the same time to print a 15-line summary of the last 15 failures. If there are more than 15, the oldest line is dropped off and the latest line is added.
SMCB Wiring Instructions These instructions cover the Healy Systems SMCB used with the Model 6280 System Monitor. Follow all caution notices and make sure all power is turned off while making connections. Make sure all power is on the same phase, including that of the gasoline pump motor relays. Note: All Class 2 wiring is being run as Class 1 and can be run together per the Article 725 of the NEC. The use of shielded, twisted pair wire (18AWG min.) is recommended for remote sensor wiring.

6275 Vent Sensor Assembly Installation of the 6275 Vent Sensor Assembly The Healy System 6275 Vent Sensor Assembly consists of the vent sensor body assembly plus the Model 6275 Pressure Switch. In addition, a +1.5" WC pressure vent valve is mounted on top of the sensor, with the designation HPV1.5. This unit is intended for use only with the 6280 System Monitor and must be installed in parallel with the +3" / -8" WC CARB-approved pressure / vacuum vent valve P / N HPV V. Refer to Figures 5 & 6.

9800-1 Pressure Switch The Healy Model 9800-1 Switch is UL Listed for use in Class 1, Group D Locations in conjunction with a Healy System Monitor. The switch is factory set at approximately 65" WC and should not need adjustment in the field. Refer to the previous Vent Sensor section for more detailed information. Mounting The 9800-1 Vacuum Switch is mounted on the Stage II Vapor Return line from the dispensers, usually in a pit or sump at underground systems outside the building.
Note: There is a small dead-band in the switch, which prevents the switch from making contact at the same number on a decreasing vacuum. Be sure adjustments are always made on an increasing vacuum and that the vacuum is allowed to decay before rechecking the switch point. 9800-1 Test Procedure CAUTION: Use extreme care when verifying the switching action. Use a digital multi-meter set to DC Volts in the 25-volt DC range.
System Program The Healy Model 6280 System Monitor is supplied with two 3.5” floppy disks to load in a laptop / personal computer (not Healy supplied) using a 9 pin straight through pin-topin RS232 cable (not Healy supplied). Downloading Parameters Some of the Model 6280 Healy System Monitor parameters can be customized for individual applications. Since parameters can be configured for each user, a program was created to support this need.
Vacuum Parameters Max. Startup Time (Sec) Max. Vac Err. Before Alarm The time allowed for the vacuum to reach a normal level. This value cannot exceed the Maximum Errors Before Alarm number. If it does an audible alarm sounds. For example, if the Maximum Start-Up Time equals 15 seconds and the Maximum Errors Before Alarm equals 3, and if the vacuum does not reach a normal level on three consecutive vacuum pump start / stop cycles, the audible alarm sounds. Factory set to 15 seconds.
Refer to the table below for explanations of the printout shown on the previous page. 18 Vent Test Period as established by CARB. This 24 hour period cannot be changed by the customer. 19 Is the maximum vent period as established by CARB and cannot be changed by the customer. This 10 hour period cannot be changed by the customer. 20 The System Time is the total amount of time the system has been powered, not just the time dispensing is authorized.
Changing Paper / Ribbon Cartridge Guide Note Before replacing the paper or ribbon cartridge, read all the instructions and locate the paper feed button on the back panel of the 6280 System Monitor. Replacement Part Numbers: 628028 Printer Paper Roll 628029 Printer Ribbon Cartridge Replacing the Printer Paper Roll 1. Remove the front panel by grasping the edges (not the top) of the black printer cover panel and slide down (See Figure 11). 9.

FIELD TEST GUIDE HEALY 6280 MONITOR SYSTEM These tests are to determine if the 6280 System Monitor is detecting switch closures correctly. Note: This must be done with no fueling positions active at the time of testing. Identify the wires from the monitor cable as follows: they all should be numbered and / or colored. • Wire number 9 is white, going to the common of CB1. • Wire number 10 is black, going to –12VDC. • Wire number 11 is blue, going to the common of the 6275 Vent Sensor.
HEALY 6280 MONITOR TROUBLESHOOTING GUIDE APPLICATION: The Model 6280 System Monitor can go into three specific alarm conditions, “NO VACUUM” FAILURE, “VACUUM” FAILURE, OR “EXCESS VENT” FAILURE. The failure responsible for the alarm sounding can be determined by reviewing the 6280 System Monitor “Failure History” printout. To generate this printout, simultaneously push both RESET buttons.
SYMPTOMS: “VACUUM” FAILURE This failure occurs when the 6280 System Monitor does not receive a signal from the pressure switch of 65" WC within 15 seconds of the start of the vacuum source for three consecutive times. Possible Causes Solutions 1. Significant leak in the vapor line. (9000 Mini-Jet or VP500) 1. Test vapor recovery lines for leaks. Repair as needed NOTE: Refer to vapor line test procedures. (9000 MiniJet or VP500) 2. Vacuum source failure. (9000 Mini-Jet or VP500) 2.
SYMPTOMS: “EXCESS VENT” FAILURES This failure occurs when the vent sensor records more than 10 hours of venting in a 24 hour period. 1 22 Possible Causes Solutions Leak in the Stage II line allows ingestion of air into system. This creates vapor growth in the tank and emissions at the vent. (9000 Mini-Jet or VP500) 1. Test vapor recovery lines for leaks. Repair as needed. (9000 Mini-Jet or VP500) 2. Pressure valve above the vent sensor not operating properly and allowing emissions.
