Operating Controls And Procedures; Models 1, 3, 4, 5, And - IBM 1402 Manual

Models 1, 3, 4, 5, and 6
The keys, lights, and switches on Models 1,3,4, 5, and 6
are alike (Figure 4). Several of the controls are common
to the entire 1402; others are specifically for the reader
or punch portions.
Common Controls
Start Key* is used to initiate machine operation after a
manual, programmed, or automatic stop.
Stop Key* is used to stop the system. If a program step
is in process, it is completed before operation stops.
Check Reset Key must be pressed to reset any punch or
read error indication (punch check, reader check, punch
stop, reader stop, transport error, or validity error), so that
the start key will be effective for resuming operation. The
check reset key is effective only when the feed unit in
which the error occurred is cleared of cards.
Power Light is on when power is supplied to the machine.
Fuse Light,indicates that something in the 1402 circuitry
caused a signal fuse to burn out. A customer engineer
should be notified.
Transport Light indicates a card jam in the transport area.
After the card jam is cleared, the light turns off. Any cards
beyond the read brushes in the read feed (or the punch
check brushes in the punch feed) have been read (or
punched) and checked.

Interchangeable with the same key on a system console or on
an IBM 1403 Printer.

OPERATING CONTROLS AND PROCEDURES
Stacker Light signals that a stacker is full. When enough
cards are removed to allow the stacker slide to return
beyond the stacker trip device, the stacker light turns
off. Operations can be resumed by pressing the start key.
Reader Controls
Load Key is used to start the loading of program instruction
cards in the read feed. Pressing the load key operates the
read feed until a card has passed the read station. The
read-in area (positions 1-80 of storage) is automatically
cleared, and a word mark is set in address 001.
After the first card is read at the read station, the
program begins by executing the instruction punched in
the first columns of the card. Continued operation, in-
cluding further feeding and reading of program cards,
is under program control and does not require operator
intervention.
When the punch onloff switch is on, operating the load
key also starts the punch.
Nonprocess Runout Key (NPRO) is used to clear cards from
the read feed. The key is operable only when the read
hopper and me feed tray are empty (or manually prevented
from feeding cards), and the joggler gate is closed. In normal
circumstances the last two cards that enter the NR stacker
have not been read.
Note: The NPRO key should be operated before loading
cards into the read feed for the first time after power has
been turned on.
Reader Stop Light signals a card-feed failure, a card jam,
or a clutch failure. It also comes on if the NPRO key has
been pressed. The stop light can be turned off by pressing
the 1402 check reset key after the condition causing the
stop has been corrected.
