Down Stream Valve Leak Test
This test confirms or troubleshoots leaks in components
located down stream of the dosing valves. Use this test
to detect closed or worn valves, and to detect leaks in
circulation valves installed at a remote mix manifold.
1. Close both mix manifold valves downstream of the
dosing valves.
2. Close recirculation valves (AC, AD).
3. Enter Test mode in the run (fluid control) screen.
See Test Screens on page 78. Select
to
run down stream valve leak test.
4. Select
. Press . Ensure dosing valves
(AA, AB) are open by verifying blue LEDs are
illuminated for both dosing valves.
5. If test is successful, both metering pumps will stall
against the downstream valves when the dosing
valves (AA, AB) are open. If any movement is
detected in the metering pumps after stalling, an
alarm is issued indicating which side has a leak.
