When changing the
24CJ5, Model 3000 to the 70D30-71D80-72DRT1
24CU6 Model 1050 to the 70D30-71D80-72DUV1
26CF6, Model 1000 to the 70D30-71D80-72DIR1
do the following:
— Replace the wiring base with P/N 60-1386-2 or P/N 60-1466-2.
— Replace wires on corresponding terminals except as noted below.
— The existing STARTING INTERLOCK circuit (3 to D) must be changed to M to D.
— The existing RUNNING INTERLOCKS remain between 3 and P.
IMPORTANT: The STARTING INTERLOCKS and RUNNING INTERLOCKS must be
isolated from one another.

— Replace wires on corresponding terminals.
MAINTENANCE
Type 48PT2 Infrared and Type UV1, UV8A, UV2, and 45UV5-1009 UltraViolet Scanners
The viewing area of the scanner must be kept clean. Even a small amount of contamination will
reduce the flame signal reaching the detector by a measurable amount. Wipe the viewing area rou-
tinely using a soft cloth dampened with concentrated detergent.
Type 48PT2 scanners include a replaceable #4-263-1 Firetron cell.
Type 45UV5-1009 scanners include a replaceable #4-314-1 UV tube.
Type 69ND1 Flame Rod.
The flame rod and its insulator should be kept clean by washing routinely
with soap and water. Rods should be routinely replaced as they oxidize.
Flame Signal Strength.
Routine observation of the flame signal strength on a DC test meter plugged
into the test jack of the Amplifier will forewarn of any deterioration in the capability of the flame
detector or its application.
Contacts.
There are no accessible contacts in the Fireye D30 Series control. Where contacts are
used, their design assures long trouble-free life when the load circuits are maintained within the pub-
lished load ratings.
Humidity.
In areas of high humidity, the control chassis should be removed and placed in a dry
atmosphere when the system is expected to be out of service for an extended period.
Periodic Safety Check.
A procedure should be established to test, at least once a month, the com-
plete flame safeguard system. This test should verify the proper operation of all limit switches and
safety interlocks as well as flame failure protection and fuel safety shutoff valve tightness.
Rotation.
It is recommended that control and scanner units purchased as spares be installed periodi-
cally.
