Downflo Oval, DFO 1-1 to 3-3

 30

Problem

Probable Cause

Remedy

Alarm light is ON

Alarm setpoint too low

Adjust to a higher value.

Excess pressure drop

Check cleaning system and compressed air supply. 

Replace filters if filters do not clean down.

Pressure tubing disconnected, 

ruptured, plugged, or kinked

Check tubing for kinks, breaks, contamination, or 

loose connections.

Delta P arrow keys to not 
work

Improper operation

Press and hold one of the three setpoint keys to use 

arrow keys.

Programming keys disabled

Remove the Program Disable jumper from Terminals 

3 and 4 on TB2.

Cleaning light is ON, 
but cleaning system not 
functioning

Improper wiring

Check wiring between the Delta P Control and 

the timer board, and between the timer board and 

solenoid valve coils.

Defective solenoids

Check all solenoid coils for proper operation.

Timer board not powered

Check power ON light on timer board's LED display. 

If not illuminated, check the supply voltage to the 

timer board. Check the fuse on the timer board. 

Replace if necessary.

Timer board defective

If LED is illuminated, observe the output display. 

Install a temporary jumper across the pressure 

switch terminals.  Output levels should flash in 

sequence.  Check output using a multimeter set to 

150-Volt AC range. Measure from SOL COM to a 

solenoid output.  The needle will deflect when LED 

flashes for that output if voltage is present.  If LED's 

do not flash, or if no voltage is present at output 

terminals during flash, replace the board.
