SECTION III.
TYPE 123 CARD READER
Auxiliary Control Panel Indicators
The indicators on the auxiliary control panel are illuminated only when the conditions
described below exist.
NOTE:
If
one of the following indications occurs, it is necessary to press
the POWER OFF switch before the POWER ON switch is pressed.
POWER
The POWER indicator is illuminated when a logical voltage
fails or when one of the logic power circuit breakers opens.
The READER indicator on the main control panel is also
illuminated.
PICKER
HEAT
OPERA TING PROCEDURES
The PICKER indicator is illuminated when the picker motor
drive circuits fail in a manner causing the picker motor to
run at a speed that is injurious to
th~
mechanism.
The
READER indicator on the main control panel is also illuminated.
When a PICKER indication occurs, the service engineer
should be called.
The HEAT indicator is illuminated when one of the cooling fan
fails.
The READER indicator on the main control panel is
also illuminated.
When a HEA T indication occurs, a service
engineer should be called.
The Type 123 reader is designed to read standard 80-column cards.
The reader may also
~
process 51-column punched cards when the 51-Column Card Capability (Feature 1043) is included.
Cards are loaded face down, nines edge first into the input hopper.
Cards may be loaded into
the input hopper or removed from the output stacker while cards are being processed.
Initial Setup Procedures
If
it is necessary to process cards with irregular right-hand edges, the appropriate refer-
ence edge selection must be made.
The Type 123 is designed to be compatible with cards having
a reference edge either between card rows six and seven or betweens rows seven and eight.
The
reference edge is the trailing edge of the card; i. e., the right-hand edge of the card
if
it is
viewed face up with the nines edge at the bottom.
When processing normal cut cards, either reference edge track may be used by the elec-
tronic checking and timing circuits of the card control.
When processing cards which have been
burst from either longer cards, card sets, or continuous forms (such as those used on a printer),
the referenced edge may be somewhat irregular and may require an operator selection of the
appropriate reference edge track to permit proper sensing of the trailing edge of the card.
The appropriate track is selected by setting the toggle mechansim in the reader to the
