Static Checkout; Equipment Recommended; General Instructions - Honeywell RM7800L1087 Installation Instructions Manual

STATIC CHECKOUT

After checking all wiring, perform this checkout before
installing the RM7800L/40G,L, 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/40G,L,
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/40G,L, 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.

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/40G,L, EC7840L model being tested.
4. Raise the setpoint of the operating controller to sim-
ulate a call for heat.
5. For each test, open the master switch and install the
jumper wire(s) between the subbase wiring termi-
nals listed in the Test Jumpers column.
6. Close the master switch before observing operation.
7. Read the voltage between the subbase wiring termi-
nals 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 termi-
nal screws, correct wire, and proper wiring tech-
niques. Replace all damaged or incorrectly sized
wires.
10. Replace faulty controllers, limits, interlocks, actua-
tors, 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.
