SERVICE NOTE:Clipping and removing a site-configurable jumper enhances the level of safety. Removal after 200 hours of
main valve operation will result in a hard lockout, Code 110.

STATIC CHECKOUT

After checking all wiring, perform this checkout before
installing the RM7845A on the subbase. These tests verify the
Q7800 Wiring Subbase is wired correctly, and the external
controllers, limits, interlocks, actuators, valves, transformers,
motors and other devices are operating properly.
WARNING
Explosion and Electrical Shock Hazard.
Can cause serious injury, death or equipment
damage.
1. Close all manual fuel shutoff valve(s) before starting
these tests.
2. Use extreme care while testing the system. Line
voltage is present on most terminal connections
when power is on.
3. Open the master switch before installing or
removing a jumper on the subbase.
4. Before continuing to the next test, be sure to
remove test jumper(s) used in the previous test.
5. Replace all limits and interlocks that are not
operating properly. Do not bypass limits and
interlocks.

CAUTION
Equipment Damage Hazard.
Improper testing can damage equipment.
Internal surge protectors can break down and conduct
a current, causing the RM7845A to fail the dielectric
test or possibly destroy the internal lightning and high
current protection. Do not perform a dielectric test with
the RM7845A installed.

Equipment Recommended

1. Voltmeter (1M ohm/volt minimum sensitivity) set on the
0-300 Vac scale.
2. Two jumper wires; no. 14 wire, insulated, 12 inches
(304.8 mm) long with insulated alligator clips at both
ends.
