3.0 Use as: Multiple Station Injector - Up to Three (3) Injection Rates
The ProPAC-3 injector maintains three distinct channels, and each channel maintains a set of counters
providing the capability of totaling additive and product for each dedicated channel. For example, a single
injector can total and account for additive at three different injection rates. Injection rate selection must be
made via a dedicated hardware Permissive Input or via the serial communications protocol. Hardware
inputs are typically provided by the users TAS (Terminal Automation System). When a specific input is
received, the injector will inject the programmed injection rate for the selected input during the product load
period. Provided three users share the same additive, the ProPAC-3 can inject and totalize additive and
product loaded for all three users from a single injector. If serial communications is established, an infinite
number of injection rates are available.
When the ProPAC-3 is used as a multiple station injector and wired utilizing the Permissive Input feature,
the following is required, as a
minimum
, in order for the injector to function:
1.
Power (120 VAC/60 Hz. / 230 VAC/50 Hz.)
2.
Product Pulse (AC or DC)
3.
Authorize feature (programmed Enabled)
4.
Permissive Input feature (programmed 1,2, or 3)
Recommended product features for implementation:
1.
Permissive Output
(AC or DC) - used to terminate product loading in the event of an injector
alarm, ProPAC-3 power failure, or the Pro PAC-3 power switch being positioned OFF
2. Serial Communications
- used to document regulatory compliance for additive/product loaded,
as well as, record injector alarms
3. Confirmation Pulse Output
(AC, DC, or mechanical) - used to terminate product loading in the
event of the failure of the product pulse. Typically used when a flow switch input is not used.
Note:
The confirmation pulse output module is located at position Output 2, on the Pro PAC-3
main circuit board.
3.1 Multiple Station Injector - Idle State Operations
In the Idle State (no Permissive Input received), the graphical display will cycle between the Grand Total
Screen, and the Channel Total Screens. Therefore, a terminal operator may daily view and record the
channel specific totals as well as the Grand Total screen (cumulative additive and product totals for all
channels) without having to physically access the ProPAC-3 injector electronics.
