Figure 11: Device Spin Down/Up Timer Switch
Adjusting the Spin Down/Up Timer
The timer for device spin down is controlled by a small selector, located in a cutout on the side
of the DE200 receiving frame as shown in Figure 11. When the key is turned to the OFF position,
and when the timer receives a NO SCSI Activity signal from the Isolator Board, it waits the
specified delay time before displaying a “u” on the front panel of the receiving frame. The
amount of time required for a disk drive to spin down is approximately 15 seconds or more.
This number can vary depending on the type of SCSI device and manufacturer (e.g. a Seagate
Barracuda may require 45 seconds). The factory configuration is set for 20 seconds. A
different delay time may be selected with the provided alignment tool. Refer to the SCSI device
manufacturer’s manual for more information on required device spin down time.
