Operating instructions
glow green). This places the
document handler's electronics in
a
standby condition.
4.
Depress the MOTOR ON
pushbut-
ton on the control and indicator
panel (will glow green).
5. Depress the ON-LINE, OFF-LINE
MODE pushbutton on the control
and indicator panel for the desired
setting. (The ON-LINE or OFF-
LINE portions of the switch light
alternately each time it
is
depres-
sed).
6.
The document handler
is
not ready
for use until the FEED READY
light
is
illuminated; this occurs
after a delay of about a minute
following the depression of the
MOTOR ON pushbutton. (step 4).
f. Document handler (750 documents per
minute)
:
1.
For on-line operation, turn on
power to the central processor.
This turns on power to the docu-
ment handler adapter and the
'Z'
rack. (Steps 2 through
6
apply to
both on-line and off-line oper-
ation).
2.
Turn the circuit breaker switch on
the document handler to the on
position (up).
3.
Check to see that the MAIN CIR-
CUIT BREAKER indicator on the
document handler's control and
indicator panel
is
lit.
4.
Depress the POWER ON pushbut-
ton on the control and indicator
panel (glows when lit).
5.
Position the function switch on the
control and indicator panel to PRO-
CESS for on-line operation and to
SEQUENCE for off-line operation.
6.
The document handler
is
not ready
for use until the FEED READY
indicator
is
illuminated; this oc-
curs after a delay of about
a
minute
following the depression of the
POWER ON pushbutton.
The operator will now be ready to set up the individual
peripherals for
on-line operation. Directions for
loading input and output media and setting up individual
peripherals are contained in sections of this manual
under headings of the specific peripherals.
SHUTDOWN PROCEDURES
The procedures for turning power off and thereby
shutting down the GE-225 System are the opposite of
those for turning power on.
Start with the switches
most distant, electronically, from the
main power and
work toward main power.
That is, turn off power to
a
peripheral, then to the controller, then to the central
processor, and last of all, turn off the main power
switches.
Peripherals may be turnedoff in any sequence desired.
The
most convenient order will depend on physical
arrangement of the equipment. If paper tape and mag-
netic tape are to be removed
and stored, the operator
may wish to start with these units. The following
sections describe procedures for both
normal shutdown
and emergency shutdown.
Normal Shutdown
The following procedures are to be followed any time
operators go off duty and whenever service engineers
perform routine maintenance. These procedures are
designed to save data in the central processor core
memory and to prevent runaway peripherals.
1.
Magnetic tape system:
a.
Set the
REMOTE/LOCAL
switch to
LOCAL.
b.
Rewind and de-thread magnetic tapes
(remove and store
if
desired), relieve
tension on tension arms, and close
all
dust
covers and doors on tape hand-
lers.
c. Depress the POWER ON
switchon each
tape handler (light goes out).
d.
Depress the
POWER OFF switchon the
tape controller.
2.
Paper tape reader and punch:
a.
Remove and store punched tape.
b. Depress the OPERABLE switch on
control panel
if
either READER
ON
or PUNCH ON indicators are on.
c.
Depress the POWER
ON
switch (light
goes off).
