EXTERNAL METER CONNECTIONS
The test jacks are located on the amplifier card. If external access is desired for a panel meter the
shown below will assist you in locating the position to drill through on the front cover. The hole
sizes should be large enough to accommodate the body of the meter probes. The tests accept meter
probes up to .080” or 2mm diameter.
INSTALLATION TESTING
New warning for Micro-M control product bulletin
WARNING!!
Boiler operation, maintenance, and troubleshooting shall only be conducted by trained personal.
Persons troubleshooting lockouts or resetting the control must respond properly to troubleshooting
error codes as described in this product bulletin.
Jumpers being used to perform static test on the system must be used in a controlled manner and must
be removed prior to the installation of the Micro-M on the wiring base and the operation of the control.
Such tests may verify that external controllers, limits, interlocks, actuators, valves, transformers,
motors and other devices are operating properly. Such test must be conducted with manual fuel valves
in the closed position only. Replace all limits and interlocks not operating properly, and do not bypass
limits or interlocks. Failure to follow these guidelines may result in an unsafe condition hazardous to
life and property.
Use of Test Meter (All Controls)
Testing the Fireye MicroM Controls requires the use of a test AC/DC multimeter, with a minimum
1000 ohm/volt AC scale and 20,000 ohm/volt DC scale.
With the test meter on the DC scale, and the test meter leads inserted into the test jacks on the ampli-
fier (Red for positive (+) polarity, Black for minus (-) polarity), a DC voltage reading of 4.0 to 10
volts for all amplifier types should be obtained when the control is detecting flame and 0 volts when
no flame is present. Wildly fluctuating readings are an indication of an unstable flame or flame sen-
sor requiring maintenance. Inadequate flame signal may be improved by:
1.
Assuring that the flame detector and wiring installations have followed the instructions begin-
ning on page 46.
2.
Assuring that the flame detector is clean and within the ambient temperature limits.
3.
Assuring that the flame is sufficiently large to detect.
4.
Assuring that the flame quality (fuel to air ratio, combustion air velocity) is satisfactory.
5.
Trying a shorter sight pipe or increasing the sight pipe diameter. (The burner manufacturer
should be consulted before mechanical changes are made).
