4. OPERATIONS
INTRODUCTION
The operator controls, loading procedure, and unload ing
procedure for Models 7120, 7121, 7122, and 7140 are de-
scribed in this section.
OPERATOR CONTROLS (MODEL 7120)
The Model 7120 control panel consists of four switch-
indicators mounted on the front panel (see Figure 8).
Figure 8. Model 7120 Card Reader Control Panel
OPER'L/POWER
This push-on/push-off, split field, switch-indicator con-
trols ac power to the card reader. Nonillumination of the
OPER'L/POWER switch-indicator indicates ac power is not
appl ied.
When the switch is momentarily pressed, ac
power is applied and POWER is illuminated (green).
OPER'L is illuminated (white) if ac and system dc power are
on and the read station and transport mechanism are operative.
START
Operation of this momentary switch-indicator places the
card reader in the "automatic" mode and illuminates the
START indicator (white) if the unit is operational, the input
hopper is not empty, and none of the multiple stackers is full.
In addition, if a card is not present on the card read plat-
form, operation of the START switch feeds one card from the
input hopper onto the card read platform.
The indicator
is extinguished and the unit enters the "manual
II
mode if
any of the following conditions occurs:
10
The STOP switch is operated.
20
One or more of the output stackers are full.
3.
The input hopper is empty.
4.
The unit becomes not operational.
FAULT/RESET
The FAULT indicator of this split field, switch-indicator
is ill uminated (red) only when a read station faul t or transport
16
Operations
mechanism fault is encountered.
Transport motor power is
removed when any transport mechanism fault occurs, such as
failure to feed a card from the input hopper to the card read
platform or a card jam in the transport mechanism. Illumi-
nation of the FAULT indicator normally indicates that the
assistance of maintenance personnel is required to restore
the card reader to an operational condition.
When the card reader is in the process of reading a card,
pressing the RESET switch causes an "unusual end" condition
to be signaled to the controlling system and places the card
reader in the "manual
II
mode at the completion of the cur-
rent card read operation.
STOP
Operation of this momentary switch-indi cator changes the
card reader from the "automati c" mode to the" manua
I"
mode.
The STOP indicator is illuminated (white) only while the
unit is in the "manual" mode, with the current card read
operation (if in process) being completed.
OPERATOR CONTROLS (MODELS 7121/7122/7140)
The control panels for Models 7121, 7122, and 7140 Card
Readers consist of four switches and eight indicators (see
Figures 9 and 10).
Figure 9. Models 7121/7122 Card Reader Control Panel
POWER
This control is a push-on-/push-off switch-indicator that
controls ac power to the card reader. When the switch is
pressed, ac power is appl ied and POWER is illuminated.
Nonillumination of the switch indicates that ac power is not
applied.
START
Operation of this momentary switch-indicator places the
card reader in the "automatic" mode if the unit is opera-
tional, the input hopper is not empty, and no output
stacker is full.
