TROUBLE SHOOTING
The Robonic is energized; proceed with care!
A. Gen-Set Does Not Start When Test Switch is
Operated and Held in “Test” Position.
1. Check Operation. Make sure the Test Selector
Switch is held in “test” position longer than the TDES
time delay.
2. Check Engine Controls. Make sure control is in “Au-
tomatic” position. Make sure batteries are charged
and connected. Make sure engine start circuit is
wired.
3. Check Wiring. Make sure the start signal wires from
the engine controls are connected to the correct ter-
minals on the Control Panel. See the Schematic/
Wiring Diagram.
4. Check Signal Circuit. Disconnect and tape start sig-
nal wires. Connect the ohmmeter between the con-
trol panel terminals 51 and 52. The reading should
indicate an open circuit. Turn the Test Selector
Switch to “Test” position. After TDES time delay, the
ohmmeter should indicate a closed circuit.
B. Robonic Does Not Retransfer the Load After
Normal Source is Returned or After Test Switch
is returned to “Auto’ position.
1. Check Operation. Make sure time has passed to
allow for TDEN time delay.
2. Check Normal Source Voltage Levels. On a three
phase system voltmeter should read phase to phase
voltage.
3. Check Signal Circuit. Confirm that the Test Switch
has reclosed to measuring 0 volts between termi-
nals T60 and T61.
C. With Gen-Set Running, Robonic Does Not Trans-
fer the Load to Emergency.
1. Check Operation. Make sure time has passed to
allow for TDNE time delay.
2. Check Engine Controls. Check generator output fre-
quency and voltage. Output should be at least 90%
of nominal voltage and 95% of nominal frequency.
Make sure generator output circuit breaker is closed.
3. Check Wiring. Voltmeter should read phase to phase
voltage between Transfer Switch EA and EB.
D. Robonic Retransfers the Load, but Gen-Set Con-
tinues to Run.
1. Check Operation. Make sure time has passed to
allow for TDEC time delay.
2. Check Engine Controls. Make sure engine starting
control is in the “Automatic” position.
3. Check Signal Circuit. Disconnect and tape start sig-
nal wires which are connected to the control panel
terminals 51 and 52. Connect ohmmeter between
these terminals; reading should indicate an open
circuit.
RECOMMENDED MAINTENANCE
1. DO NOT perform dielectric tests on the equipment
with the control components in the circuit.
2. DO NOT use loctite.
3. Check lubricant in high speed bearings of the motor
and the low speed bearings of the gear box. For
lubrication use Dow Corning Silicon DC44 or equiva-
lent on the high speed bearings and Aero Shell No.
6 grease or equivalent in gear box after 5000 opera-
tions.
4. Check if control components are tight in sockets.
5. Periodically inspect all terminals (load, line and con-
trol) for tightness. Re-tighten all bolts, nuts and ac-
cessible hardware. Clean or replace any contact
surfaces which are dirty, corroded or pitted.
6. Robonics should be in clean, dry and moderately
warm locations. If signs of moisture are present,
dry and clean transfer switch. If there is corrosion
try to clean it off. If cleaning is unsuitable, replace
the corroded parts. Should dust and/or debris gather
on the transfer switch, brush, vacuum or wipe clean.
DO NOT blow dirt into breaker or terminals.
7. Test the transfer switch operation. While the Robonic
is exercising, check for freedom of movement, hid-
den dirt or corrosion and any excessive wear on the
mechanical operating parts. Clean, lubricate or re-
place parts where necessary.
8. Check all adjustable control components (time de-
lay and voltage sensing relays) for correct settings.
9. If the type “RO” mechanism is removed be sure that
the scribe lines on the gears are in line. When re-
assembling the drive mechanisms, be sure that they
are fastened to the correct holes in the frame and
that the breaker handles are between the cam fin-
gers. (One breaker has to be on and the other off.)
