3. Make sure no subbase wiring is projecting beyond
the terminal blocks. Tuck in wiring against the back
of the subbase so it does not interfere with the knife
blade terminals or bifurcated contacts.
IMPORTANT
Install the relay module with a plug-in motion
rather than a hinge action.
4. Mount the relay module by aligning the four L
shaped corner guides and knife blade terminals with
the bifurcated contacts on the wiring subbase and
securely tightening the two screws without
deforming the plastic.
STATIC CHECKOUT
After checking all wiring, perform this checkout before
installing the relay module on the wiring subbase. These
tests verify that the Q7800 Wiring Subbase is wired
correctly and the external controllers, limits, interlocks,
actuators, valves, transformers, motors and other devices
are operating properly.
For further checkout and troubleshooting, see form 65-
0229.

Honeywell has tested this output at 9.8A at PF = 0.5, 58.8A inrush for 100,000 cycles (EN298 approval does not require
this test).

220/240 Vac to 120 Vac, 10 VA stepdown transformer (not provided) must be used to drive the shutter. Transformer
does not apply to UV flame sensor models C7061A1020, C7061A1079 and C7061F1003 (combined with R7861-series
flame amplifiers), which have internal selectable terminal block to connect 230V shutter output directly.
