INTRODUCTION
The DC68K Pack Controller (referred to as the DC68K in this manual) provides control
for both suction and discharge of up to four packs (i.e. two LT and two HT packs)
An LCD display and keypad enable settings to be programmed and current status to be
viewed. Control is affected via RS485 serial communications from the DC68K to remote
serial I/O units (PACK-IO boards) A second RS485 serial communications port is
provided for communications to a Storescan III alarm panel, this link is required for
floating the suction pressures. For information on programming the DC68K from the
Storescan please consult the Storescan manuals.
The PACK-IO boards will relinquish control to the mechanical backup in the event of a
power/communication fault to the DC68K pack controller.
