aXis CONTROLLER HOME STANDBY GENERATOR
INSTALLATION
38
1. Place aXis Controller module in the OFF position and remove
aXis Controller module fuse.
2. Turn ON the utility power supply to the ATS.
3. With an AC voltmeter, check for the correct voltage. Single-
phase utility power supply. Measure across the UTILITY
SUPPLY ATS terminal lugs L1 and L2. Also check L1 to
NEUTRAL and L2 to NEUTRAL.
4. The utility supply voltage should be correct and compatible
with the ATS ratings.
5. Turn OFF the utility power supply to the ATS.
6. The Control Panel MAIN CIRCUIT BREAKER must be in the
OFF position.
7. Set the aXis Controller Module in the MANUAL mode. The
HSB will crank and start. Let the HSB warm up at no load for
5 minutes to stabilize performance.
8. Set the Control Panel MAIN CIRCUIT BREAKER in the ON
position.
DANGER
Proceed with caution. HSB generator output voltage is now
being delivered to the ATS and is electrically hot. The feeder
lines and terminals are now live.
Contact with these connections will result in extremely
hazardous and possibly fatal electrical shock
9. With an AC voltmeter, check the correct voltage. Single-phase
generator supply.
10. Measure across GENERATOR SUPPLY ATS lugs L1 and L2.
Also check L1 to NEUTRAL. These are factory pre-set limits.
Frequency .................................................................. 62.5 Hertz
Terminals L1 to L2 ..........................................................240 VAC
Terminals L1 to NEUTRAL ...............................................120 VAC
Terminals L2 to NEUTRAL..............................................120 VAC
11. Set the HSB generator MAIN CIRCUIT BREAKER to its OFF
position.
12. Set the aXis Controller module to the OFF position. This will
shut off the HSB.
HSB TESTS UNDER LOAD
During this test you DO NOT need to turn off any circuit
breakers in the Utility Main Distribution Panel, HSB Control
Panel or the ATS.
This procedure will verify load Voltage and frequency output. Prior
to starting the test you can place a Manometer in line to check
fuel flow when the HSB is near rated load.
1. Remove ATS dead front.
2. Assure DIP switch #9 (TEST WITH LOAD is in the ON position.
