1.0 Introduction
The injector may be used in its simplest form as a single station injector requiring only power and product
pulses in order to operate, or it may be programmed, wired and used to operate as a multiple station (rate)
injector, thereby, taking advantage of the many system features designed into the product.
2.0 Use as: Single Station Injector - One Rate
The ProPAC-3 may be used in its simplest form as previous injectors that are used to inject a single additive
at a single injection rate. In this example, the "Authorize" feature is programmed Disabled, and Permissive
Inputs are not used. Note: Although the injector is used as a single station injector, it may be used to inject
multiple injection rates, via the RS-485 serial communications.
When the ProPAC-3 is used as a single station injector with no serial communications installed, the
following is required as a minimum, in order for the injector to operate:
1.
Power (120 VAC/60 Hz. / 230 VAC/50 Hz.)
2.
Product Pulse (AC or DC)
Note
: The product pulse input module located at position “Input 1” on the ProPAC-3
Motherboard must conform to the input voltage provided. See Field Installation section.
Minimum recommended product features for implementation:
Permissive Output
(AC or DC) - used to terminate product loading in the event of an injector
alarm, ProPAC-3 power failure or the ProPAC-3 power switch being positioned OFF.
Serial Communications
- used to document regulatory compliance for additive/product loaded as well ell
as record injector alarms
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. See Field Installation Section
2.1 Single Station Injector - Idle State Operation
The ProPac-3 is in the idle state when waiting for product pulses. The ProPac-3 displays the screen below
when in the idle state, on which both the Additive and the Product totals are indicated. When used as a
single station injector (one rate), Channel 1 (Ch1) is the designated channel used to accumulate totals. The
additive total and the product total are both cumulative totals, since system start-up, or since the totals have
been reset.
