a
Pilot Valve /First Stage Oil Valve Terminal 21 cannot be used in this arrangement if Valve Proving feature is selected.
b
A 30-second MFEP can be accomplished by adding a jumper wire between terminals 19 and 5, ignored if VP is active.
c
DSI Enabled allows for Valve Proving test to be performed, then during PFEP both terminals 9 and 21 energize to light the
Main Flame—note PFEP will not occur and the MFEP will automatically be 4 seconds regardless.
STATIC CHECKOUT
After checking all wiring, perform this checkout before
installing the RM7800L/40L, EC7840L 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 RM7800L/40L, EC7840L to fail
the dielectric test or possibly destroy the internal
lightning and high current protection. Do not perform a
dielectric test with the RM7800L/40L, EC7840L
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.
3. Ammeter can be used to verify valve loads connected to
the wiring subbase.
General Instructions
1. Perform all applicable tests listed in Static Checkout,
Table 8, in the order listed.
2. Make sure all manual fuel shutoff valve(s) are closed.
3. Perform only those tests designated for the specific
RM7800L/40L, EC7840L model being tested.
4. Raise the setpoint of the operating controller to simulate
a call for heat.
5. For each test, open the master switch and install the
jumper wire(s) between the subbase wiring terminals
listed in the Test Jumpers column.
6. Close the master switch before observing operation.
7. Read the voltage between the subbase wiring terminals
listed in the Voltmeter column.
8. If there is no voltage or the operation is abnormal, check
the circuits and external devices as described in the last
column.
9. Check all wiring for correct connections, tight terminal
screws, correct wire, and proper wiring techniques.
Replace all damaged or incorrectly sized wires.
10. Replace faulty controllers, limits, interlocks, actuators,
valves, transformers, motors and other devices as
required.
11. Make sure normal operation is obtained for each
required test before continuing the checkout.
12. After completing each test, be sure to remove the test
jumper(s).
WARNING
Explosion Hazard.
Can cause serious injury or death.
Make sure all manual fuel shutoff valves are closed
before performing static checkout.
