1.0 AGV5 SERVICE AND REPAIR MANUAL OVERVIEW
The AGV5 Gas Metering Valve has been designed to provide reliable operation with a minimum
amount of maintenance. To ensure optimum performance, periodic inspection and cleaning is
necessary.
Preventative maintenance issues can be integrated into the current maintenance schedule of the
engine. Most maintenance requires little effort and no downtime of the AGV5 valve.
Corrective maintenance is to be done when the AGV5 Gas Metering Valve begins to behave
erratically. Procedures have been generated to troubleshoot and to repair most minor issues.
•
External Visual Inspection –
Inspect the exterior of the valve for loose connections, frayed
wires or major structural damage
.
•
Cleaning –
Exterior cleaning will aid in the visual inspection of the external casing and ensure
good connections. Ethyl alcohol or mild soapy water can be used as cleaning agents.
•
Maintenance Log –
To facilitate troubleshooting and to establish service schedules, a
maintenance log should be kept on the valve.
•
Calibration
– Calibration of the AGV5 is performed in a controlled environment before
shipment. Since calibration of the valve requires equipment not normally available in the field,
it is recommended that the device be returned to the Altronic distributor serving your area.
Throughout this service manual service parts will be identified by the item number assigned to them
in the parts list. For example, (1a) and its position inside the AGV5 device can be found by locating
that item number on Fig.1A.
AGV UPDATES
•
In addition to the standard procedures, older
AGV5 units below S/N 1400
will require more
items (such as the pressure transducer and transducer housing) to be changed. These items
and procedures are identified by specific notes
(“When Updating Units below S/N 1400")
within the appropriate sections of the manual.
•
In addition to the repair of malfunctioning units, instructions are given in
SECTION 3.0
which
describe the process of updating an AGV5 to the current configuration of PCB assembly.
