Final Wiring Check; Static Checkout - Honeywell 7800 Series Installation Instructions Manual

EC7820A 7800 SERIES RELAY MODULES

Final Wiring Check

1. Check the power supply circuit. The voltage and fre-
quency tolerance must match those of the 7800
SERIES Relay Module. A separate power supply cir-
cuit may be required for the 7800 SERIES Relay
Module. Add the required disconnect means and
overload protection.
2. Check all wiring circuits and complete the Static
Checkout before installing the 7800 SERIES Relay
Module on the subbase.
3. Install all electrical connectors.
4. Restore power to the panel.

STATIC CHECKOUT

After checking all wiring, perform this checkout before
installing the 7800 SERIES Relay Module 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.
See Table 4. For further checkout and troubleshooting, see
form 65-0229.
WARNING
Explosion Hazard, 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 volt-
age is present on most terminal connections when
power is on.
3. Open the master switch before installing or remov-
ing 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 operat-
ing properly. Do not bypass limits and interlocks.
32-00197—01
CAUTION
Equipment Damage Hazard. High voltage
dielectric test can cause equipment damage.
Do not perform a dielectric test with the 7800 SERIES
Relay Module installed. Internal surge protectors break
down and conduct current, causing dielectric test failure
and destruction of the internal lightning and high current
protection.
WARNING
Equipment Shutdown Hazard. Improper
procedure causes lockout.
Clipping and removing a Site Configurable Jumper after
200 hours of operation results in a hard lockout (Code
110).
Equipment Recommended
1. Voltmeter (1M ohm/volt minimum sensitivity) set on
the 0-300 Vac scale.
2. Two jumper wires; no. 14 AWG (2.5 mm
lated, 12 in. (304.8 mm) long with insulated alligator
clips at both ends.
General Instructions
1. Perform all applicable tests listed in Table 4, in the
order listed.
2. Make sure all manual shutoff valve(s) are closed.
3. For each test, open the master switch and install the
jumper wire(s) between the subbase wiring termi-
nals listed in the Test Jumpers section.
4. Close the master switch before observing operation.
5. Read the voltage between the subbase wiring termi-
nals listed in the Voltmeter column.
6. If there is no voltage or the operation is abnormal,
check the circuits and external devices as described
in the last column.
7. Check all wiring for proper connections, tight termi-
nal screws, and appropriate wire and wiring tech-
niques. Replace all damaged or incorrectly sized
wires.
8. Replace faulty controllers, limits, interlocks, actua-
tors, valves, transformers motors and other devices,
as required.
9. Make sure normal operation is obtained for each
required test before continuing the checkout.
10. After completing each test, be sure to remove the
test jumper(s).
