2.3 Single Station Injector - Alarm State Operation
There are numerous alarms provided by the Pro PAC-3. Alarms are discussed in great detail in the Alarm
Section of this manual.
Alarms are typically used in an integrated control system where product loading will be terminated
immediately in the event of an injector alarm. The termination of product loading insures the additive to
product ratio is within prescribed limits, as specified by the user, for the entire product load. Provided the
specific alarm has been programmed Enabled, anytime the injector enters an Alarm State, the Alarm State
Screen shall be automatically displayed and will alternate, at five (5) second intervals, with any of the other
viewed screens. For example, if the injector is loading when the alarm occurs, the Alarm State Screen will
alternate (5 second intervals) with the Load State Screen (Fig. 5), as depicted in the example below.
Note:
1.
The termination of product loading during periods of active injector alarms is
absolutely necessary
if the
user intends to insure no product leaves the terminal without the minimum concentration of additive.
2.
The alarm display will show
inverted colors
from normal (white background with blue letters), making
an active alarm more highly noticeable to local terminal personnel.
3.
Alarms may be cleared by the following three methods:
a.
External “Push to Test” button provided when depressed Clears Alarms.
b.
Cycling the ProPAC-3 power OFF to ON.
c.
RS-485 serial communications protocol command.
