This page specifies the differential pressure levels to initiate and
terminate the pulsing sequence. The user needs to program four
differential pressure levels
Low = Low Differential Pressure. When the differential
pressure drops below this value the ECo will stop pulsing
the solenoid valves.
High = High Differential Pressure. When the differential
pressure is between the Low and High settings then the ECo
will use the OFF time 1 setting to pulse the solenoids valves.
Fast = Higher Differential Pressure. If the differential
pressure keeps increasing past the High setting, then the
dust collector is not pulsing frequently enough. When the
differential pressure exceeds the Fast setting then the ECo
will use the OFF time 2 setting to pulse the solenoids valves.
Alarm = Alarm level. If the differential pressure continues to
increase, then the dust load is either too high or there has
been multiple failures of the solenoid valves.
To alter the differential pressure values, select the left DOWN or
right UP buttons. When the desired units have been selected enter
the middle SET button.
Maintenance Mode
Maintenance mode allows the user to manually pulse and test the valves. Keep pressing
NEXT until the Maintenance page is displayed.

This page allows the user to select the valve to test.
To select the valve to pulse, select the left DOWN or right UP
buttons. When the valve to be tested has been selected hit the
middle PULSE button to test the valve

text and will be one of the following three possibilities
OK – The solenoid valve is functioning correctly
SC – The solenoid valve is showing a short circuit. This could
mean the
OC – The solenoid valve is showing an open circuit. This
could mean the valve is not connected or the coil has burnt
out.
