REPLACING PARTS
The Robonic Automatic Transfer Switch has been designed
to have all components accessible and readily removable
from the front of the panels. The Robonic Transfer Switch
is divided into two basic sections. The upper section con-
sists of the main contacts and transfer mechanism, the
lower section consists of all the automatic control devices.
CAUTION
When replacing any parts of the mechanism, control trans-
formers or breakers, isolate the Robonic Transfer Switch
from any possible source of power.
To remove the transfer mechanism of the LRO transfer
switch, first open the cover and remove the slide pin from
the operating cam, then remove the centre bolt, the mecha-
nism will lift straight off. The breakers and transfer motor
bracket are held by four screws for ease of removal and
replacement. When replacing the mechanism, first set it
on the Robonic with the breaker handles in the holes pro-
vided and then fasten the centre bolt reasonably tight with
the mechanism fully movable with an equivalent swing
distance up and down.
To remove the transfer mechanism of the RO transfer
switch, remove the four bolts holding it, taking note of which
holes the bolts were in, then lift the mechanism straight
off. The breakers are held by two bolts at one end and the
bus connectors on the other end. The transfer motor is
mounted to the transfer mechanism cover and centre drive
gear. When replacing any part of the transfer mechanism,
be sure that the scribe lines of the gears are in a straight
row (example shown on page 5)
To prevent operation of the transfer switch while replacing
the mechanism or components, disconnect all sources of
power.
When replacing the mechanism move it about until the
breaker toggles fit between the mechanism fingers and
then fasten the bolts tightly. To test for proper operation,
first operate manually and then connect 120 volt, 60 Hertz
supply to motor leads and observe operation for free move-
ment and proper breaker operation.
All Robonic transfer switch breakers and mechanisms have
allowed some adjustments for mounting to assure proper
operation without slipping or binding. Be sure all hard-
ware is tightened sufficiently before re-energizing any
transfer switch.
To replace any of the octal plug-in relays, pull old units
straight out and insert the replacement unit. Due to the
tight fit of the receptacle and pins, you may have to move
the relay about a little to pull it out. DO NOT INTER-
CHANGE ANY RELAY WITH ANY OTHERS!
To replace any solid state logic modules, pullstraight out
and insert the replacement unit.
