Main Control Panel Switches
The switches on the main control panel of the Type 214-2 are ITlOmentary-contact switches
which are activated when pressed.
A functional description of each switch follows:
POWER ON
POWER OFF
START
STOP
RUNOUT
Pressing this switch turns on primary power in the card
reader/punch and illuminates the POWER ON indicator.
Pressing this switch turns off all power in the reader/
punch and extinguishes the POWER ON indicator.
If
the
POWER OFF switch is pressed while a card is being
processed, the effect upon data transfer is unspecified.
Pressing the START switch places the reader /punch in a
"ready" status and illuminates the START indicator.
The
START switch moves a card into the wait station (if it is
empty), resets the CARDS and INPUT indicators, and
deactivates the busy signal to the central processor.
If
the START switch is pressed when the STOP indicator is
not illuminated, no action results.
Pressing the STOP switch removes the reader/punch from
the ready status and illuminates the STOP indicator.
The
busy signal to the central processor is activated and re-
mains active until the START switch is pre s sed.
If a read
or punch instruction is in process in the card control when
the STOP switch is pressed, that instruction is transmitted
to the reader /punch and executed.
This switch is effective only when the reader/punch is
in the STOP mode.
Pressing the RUNOUT switch causes
cards to be removed from the card path without processing
(input hopper need not be emptied).
The RUNOUT switch
resets a TRANSPORT check.
If
the reader/punch stops
because an error is detected, pressing the RUNOUT switch
allows operations to be resumed after a restart procedure
has been performed.
