COMMUNICATIONS SECTION
Address
- When utilizing serial communications, each ProPAC-3 will be addressed with a unique
address identifying the unit. Address range (1-999). Each injector on a serial communication network
should have a unique address. (Program as required) If communications is not used then the address is
irrelevant.
Baud Rate
- The baud rate must be programmed when utilizing serial communications. Baud rate
selections are: 1200, 2400, 4800, 9600, 19200, 38400 and 57600. If communications is not used then the
baud rate is irrelevant.
Accuload Serial Communications
- This should be enabled whenever a Smith Acculaod is
communicating over a RS-485 communication line to the Injector. There are two modes of operation with
the Smith Accuload: 1) Product Pulses with communication verification and alarm shutdown, 2) No Product
Pulses, batch injection commands are sent to the injector via the communication link. Call Titan technical
support for detail about which mode of operation to use.
LINE FLUSH SECTION
Pre-Load Injections
- When utilizing the Additive Pre-Load feature (normally only used for line
flushing) the user specifies the number of injections the pre-loading of additive will take place, beginning at
load start. The preload feature may be used even when not utilizing any line flush method. For example,
when the injector is configured to inject every 40 gallons of product, and if the product total is not an even
multiple of 40, there could be up to 39 gallons of untreated product. However, by preloading enough
additive to treat 39 gallons of product, the problem (of 39 gallons of untreated product at the end) is
eliminated. Programmable 1-99 injections. Note: In order to use the feature, the following must be
programmed: Number of Injections, Flush Volume and the Additive Pre-Load feature Enabled.
Example:
If (5) is entered for
Pre-Load Injections
,
Additive Set
(40),
Flush Volume
(100 gal), and
Product Set
(40). Since the
Flush Volume
is 100 gallons
Flush Volume / Product Set
= number of skipped injections as
a result of the flush (100/40 = 2.5). The preload additive volume (the volume of additive not injected at
load end during the flush period) will be
Additive Set
x 2.5 (40 x 2.5) = 100 cc's. Then 100 cc's is pre-
loaded over the first five (5) injections. Therefore, if the preload additive volume is 100 cc's, the first five
(5) injections of the load will include an additional 20 cc's or (40 + 20) for a total of 60 cc's.
Flush Volume
- User enters the volume of product used to calculate the additive to be pre-loaded.
When using product line flush, the volume should represent the actual volume of product to be flushed at
load end. The software uses the Flush Volume to calculate the amount of additive that corresponds to the
amount of product used to flush. The software calculates the preload additive volume by dividing this
