STORAGE CHARACTERISTICS
STORAGE MODULE CONTROL PANEL
Figure 2-1 shows the Storage Control Panel which is mounted at the top of each 3109 Storage
Module. The Drive Voltage Control is used to adjust the meter reading to zero percent (22.5
volts). The Z and S registers are displayed on this panel, as well as three storage faults.
The indicator lamps represent an x or y drive line voltage failure and a storage parity fault.
The Control Panel on the 3103 Module is similar to the 3109 Control Panel but is laid out on
a vertical plane.
