Possible Alarms by Mode

The following table outlines the alarms that you may receive while operating the system. The alarms ar e categorized

according to each mode.

Mode Control Logic Alarms

Spray Dosing valves close for startup test; green light blinks. --
If fluid pressure is under 1000 psi (7 MPa, 70 bar), STOP. P1A
If pumps move (indicating internal leakage), STOP. FHA, FHB
If fluid pressure is more than 103% of allowed maximum, air motor shuts
off until fluid pressure drops.
None
If is pressure more than 110% of allowed maximum, STOP. P4B
Dosing valve A opens, and dosing valve B cycles to maintain ratio. --
A and B blue lights illuminate when dosing valves are operating. --
If there is not enough B component to hold ratio, dosing valve A closes
momentarily.
R2D
If A or B component is more than 5% off ratio setpoint, STOP. R1B, R4B
If A dose size is too large, STOP. B4A
A and B dosing valves close momentarily at each pump changeover. --
Park Both dosing valves open; A and B blue lights turn on. --
User opens circulation valves or sprays gun. When pump reaches bot-
tom stroke the blue light turns off.
--
If park does not complete in 10 minutes, turn off air to both motors. DEA, DEB
Circulation A and/or B dosing valves close and motor air turns on. --
If fluid pressure exceeds 3000 psi (21.0 MPa, 210 bar) on the A pump,
receive yellow light advisory.
P4A
If fluid pressure exceeds 5600 psi (39.2 MPa, 392 bar) on the A pump,
STOP.
P4A
If no movement in 10 minutes, turn off air to both motors. DEA, DEB
Pump Test Both dosing valves close; green light blinks. --
If fluid pressure is under 1000 psi (7.0 MPa, 70 bar), STOP. P1A, P1B
If pumps move (indicating leakage) STOP. FHA, FHB
Turn on A blue light, open A dosing valve, user opens sampling valve. --
Close A dosing valve on upstroke; check for no movement. DFA
Close A dose valve on down stroke; check for no movement. DGA
Open A dose valve and dispense total of 750 ml material, close valve,
turn off blue light.
--
Repeat for B side. DFB, DGB, DHB
If both pumps pass pump test, display shows two beakers of 750ml each. --
Batch Dispense Test User selects total volume desired. --
Open A dosing valve, turn on blue light, user opens sampling valve, turn
off blue light when complete.
--
Open B dosing valve, turn on blue light, user opens sampling valve, turn
off blue light when complete.
--
Display shows volume of A and B components at end of batch dispense
test.
--
Valve Test If fluid pressure is not 1000 psi (7 MPa, 70 bar), STOP. P1A
Check for no movement of pumps (stall within 10 seconds). FHA, FHB
