PROGRAM MENU DEFINITIONS
(Use with Programming Guide Section 1 pg. 17-19)
The following definitions are provided in order to assist the user in properly programming the Titan
ProPAC-3 additive injector. The definitions are also provided in order to explain the many product features
of the ProPAC-3 additive injector.
Programming features and parameters are organized into five (5) distinct sections in the ProPAC-3 program
menu. This section of the manual provides detailed definitions for the Administration, Communications,
Line Flush, and the Channel Sections of the program menu. Limited definitions are provided for the Alarm
menu, since the alarms are fully described in the dedicated Alarm Section of the manual. See Alarm
Operations Section 3.
ADMINISTRATION SECTION
Grand Additive Total
- The total represents the cumulative volume of additive dispensed through
the injector. If more than Channel 1 is used, the Additive Total for all channels is accumulated in the Grand
Additive Total. If only Channel 1 is used, the volume represents the additive total for the channel. The value
is programmable and can be reset.
Note: The Grand Additive Total does not change when a specific
channel total is changed or reset to zero.
Grand Product Total
- The total is identical to the Grand Additive Total above except the total
represents the product treated.
Permissive Input
- Represents the number of channels used. This number should correspond to the
number of rates selections, either hardware or software, from an electronic preset or terminal automation
system. Up to three (3) channels (rate selections) may be used in order to select different rates of additive.
Each of the three channels may be used and programmed with the same or different injection rates.
Consequently, a single Pro Pac-3 injector may be used to document the additive/product ratio for up to three
different injection rates. Menu selection 1,2 or 3.
Authorize
- Represents a more sophisticated way of controlling the additive injector.
Authorization must be accomplished either by serial communications command or by hardware permissive.
Rate selection is accomplished by sending either a software or hardware additive permissive signal to the
injector, requiring that Authorize mode be used whenever more than one channel is used. Up to three
different rates may be selected and accounted for in the injector. This does not limit the fact that an infinite
number of injection rates are available by changing the injection rates via the serial communications.
However, the injector can only accurately account for the additive/product ratio for three rates. When
Authorize is enabled, product pulses to the injector are ignored and the injector will scroll between the
Grand Total screen and the Channel Screen(s) until an additive permissive is received.
Even when only one rate or channel is used
, Authorize mode
is the recommended mode of injector
operation for the following reasons.
1.
Allows for simpler pulse wiring, because pulse wires can be paralleled from one pulse
source to multiple injectors.
2.
Flow pulse switching via a PLC or relays is not necessary.
3.
Allows for simpler load permissive circuit wiring, because load permissive circuit can be
looped per load arm (See Premised Permissive).
4.
Better accountability when blended products or multiple additive rate products are loaded on the
same load arm.
5.
Product pulse failures can be detected (see product pulse and Permissive timeout alarm).
Flow Switch Input
- A flow switch input, when available, is an effective means to determine a
product pulse failure. Programmable Enabled/Disabled. If no flow switch is installed, program Disabled.
