HONEYWELL R7140L2007 Flame controller

Description

Final Wiring Check
1. Check the power supply circuit. The voltage and
frequency tolerance must match those of the R7140. A
separate power supply circuit may be required for the
R7140. Add the required disconnect means and
overload protection.
2. Check all wiring circuits and complete the Static
Checkout, Table 8, before installing the R7140 on the
subbase.
3. Install all electrical connectors.
4. Restore power to the panel.
Service Notes:
Per industry standards, a conduit seal or a cable type that is
sealed is required to be installed in a device that can result in
flammable gas or flammable liquid flow through a conduit or
cable to an electrical ignition source in the event of a seal
leakage or diaphragm failure. This could be on the gas valves,
or gas or oil pressure regulators.
Check the Q520 Wiring Subbase terminals against the typical
wiring drawings, Figures 7, 8, 12, 13, 17, or 18.
If wires are attached to terminals that are unused in the
figures, DO NOT INSTALL THE R7140 until you have
identified the connections’ functions. Most likely the old
subbase terminals were used as tie points, so removing the
wires, capping with a wire nut, and tucking the wire down into
the subbase is all that needs to be done.
