Chapter 6. MAINTENANCE AND INSPECTION
(3) After removing the tube unit, mount the shutter unit only on the
flange unit using the 2retaining screws.
Handling Precautions
•
Before mounting, insert the lead wires (blue and yellow) into
the slits of the shutter unit. When mounting the unit onto the
flange unit, hold the white lead wires under the shutter unit so
that they stay in the cable guide groove.
(4) Be sure to connect the lead wires to the 4 terminals of the shutter
unit correctly.
Handling Precautions
•
The blue lead wire goes to terminal F and the yellow one to
terminal G. Connect the two wires according to the “F” and “G”
shown on the polarity indication label on the shutter unit.
zWiring check for tube and shutter units
(1) Turn on the burner controller to check whether terminals F and
G are properly connected.
(2) Measure the DC voltage between terminals F and G using a mul-
timeter or digital voltmeter.
(3) Connect the + tester probe (red) to terminal G (yellow lead wire)
and the – tester probe (black) to terminal F (blue lead wire).
Terminal Tester probe Voltage
F − 160–220VDC
G +
>> If the reading is between 160 and 220VDC, the leads are con-
nected correctly. If a negative voltage is measured, terminals F
and G are reversed.
(4) Next, measure the DC voltage (shutter voltage) between termi-
nals S1 and S2 (both lead wires are white).
Handling Precautions
•
Terminals S1 and S2 do not have a specified polarity. When
using a multimeter, before measuring the shutter voltage
check the polarity using a wide voltage range so that the
needle does not go off the scale on the minus side.
>> If the reading is between 15 and 24VDC, the leads are connected
correctly.
If the meter indicates a constant voltage, either 24 or 0VDC, the
cause is probably a wiring mistake.
