Down Stream Valve Leak Test
This screen enables users to test for closed or worn
valves down stream of the A and B dosing control
valves. It can be used to test the mix manifold
shutoff/check valves or any remote circulation valves.
While running the test, if there is continuous pump
movement on the A or B side, an error will be issued.
The error indicates a leak in the valve.
There is no confirmation screen for this test. However, if
the down stream valve leak test fails, an warning is
issued to indicate the cause of the failure.
Confirm Valve Leak Test
This screen displays when the valve leak test completes
and indicates whether the test was successful.
Information Screens
Use this screen to view diagnostic information, alarm
logs, and pump batch and grand totals. These screens
also enable users to view maintenance information for
pump and check valves, including the maintenance
schedule.
If the potlife timer is enabled the Flush Confirm icon,
displays.
Alarm
The Alarm screen displays the specific alarm code.
There are two levels of error codes: alarms and
advisories. A solid bell icon with an exclamation point
and three audible alerts indicate a alarm. And an
outlined hollow bell icon and a single audible alert
indicate an advisory.
Additionally, this screen displays the location of the error
with the top view and side view of the system. Refer to
the following table and subsections for more details.
The first number below the alarm code is the main
power supply voltage used by the electronic modules.
The voltage should read between 23 VDC - 25 VDC for
non-hazardous location systems, and 10-14 VDC for the
hazardous location systems.
The second number below the alarm code is the power
supply voltage used by the system sensors. This voltage
should read between 4.9-5.1 VDC.
The third number below the alarm code is the A side
pump dosing size. This value is displayed in volumes of
cubic centimeters (cc) and is the volume pumped on the
A side when the B side dosing valve is off. Optimizing
the restriction of the system will keep this value small
and ensure material is mixed well.
