only power and product pulses are required. If the product pulse failed, an additive injector cannot
determine when it should be injecting additive.
Cause:
When the microprocessor detects a permissive input and flow switch input, and does not
receive a product pulse input within 120 seconds, the unit will alarm. When the ProPAC-3 is in this alarmed
state, further injection attempts are prohibited.
Troubleshooting:
Check the pulse input module.
3.24 Line Flush Failed (Line Flush)
Problem:
The ProPAC-3 Line Flush feature provides the capability of flushing all additive or dye
from the product line by the end of product loading. The alarm is used in conjunction with all means
capable of product line flushing. Incomplete flushing will cause contaminated product to remain in the
product line at the end of product loading.
Cause:
The user enters the volume of product to be flushed into the program. Microprocessor
software is designed to count product volume following the initiation of the flush. The unit is programmed
to count a specific volume of product between the initiation of the flush (typically at or near initiation of
product slow flow) and the end of product loading. At the end of the product load, in the event the volume
of product is less than the programmed flush volume, the unit will alarm indicating the product line has not
been flushed properly. When the ProPAC-3 is in this alarmed state, further injection attempts are
prohibited. The alarm activates under the following conditions:
1.
Flush volume is too small.
2.
Flush alarm volume is too high.
3.
Flush Start % Decrease is set too high (Frequency Flush).
Troubleshooting:
Enable the flush diagnostic screen (See Section 1 - pg. 9). Call Titan Technical Support
for additional help.
3.25 Permissive Timeout Error (Permissive Timeout)
Problem:
It is possible a Permissive Input (hardware or software) is received by the injector, yet
no product pulses are received. If the injector software recognizes a new product load is to commence
(reason for the permissive), however, no product pulses are received within 120 seconds, the software can
not determine whether there has been a product pulse failure or whether the injector was falsely permitted
with no real intent to load product.
Cause:
The alarm may be used for applications where either hardware or software permissive
inputs are used but no flow switch is used. If the injector receives the permissive and no product pulses are
detected, for a period of 120 seconds, the alarm will activate. Note: When the permissive is removed, the
alarm will automatically reset.
Troubleshooting:
Check the pulse input module.
3.26 Flow Switch Failed
Problem:
The alarm is used to detect the failure of an installed product flow switch. A flow switch
may be installed in order to assist in the detection of a product pulse failure (see Alarm - Product Pulse
Failed). If the flow switch fails, then the failure of a product pulse cannot be easily determined, and product
could be loaded without additive and without any alarm indication.
Cause:
Provided a flow switch has been installed, when the flow switch input is wired, the alarm
will activate any time there are more than three (3) consecutive injection attempts with no flow switch
indicating product flow (flow switch-made). When the ProPAC-3 is in this alarmed state, further injection
attempts are not prohibited. Note: In order to use the feature, a product flow switch must be installed and
wired correctly to the flow switch input located on the ProPAC-3 main circuit board. Additionally, both the
Flow Switch Input and the Flow Switch Alarm must be programmed Enabled.
Troubleshooting:
First check the flow switch input module. If the problem continues, the flow
switch has probably failed.
