18 PROGRAMMING INSTRUCTIONS
18.1 DCT-500 sequencer
The card programming was factory adjusted. The valves opening time is set at 100 msec and the
delay between each opening is set at 10 seconds.
Should those delays be modified for any reason, adjust the potentiometers located at the top of
the electronic board.
"PULSE ON"
represents the opening time and the
"PULSE OFF"
represents
the delay in between each cleaning sequence.
Refer to the manufacturer’s owner’s manual for any questions concerning the DCT-500 sequencer.
Note:
Do not readjust the valves opening time
"PULSE ON"
or the delay between each cleaning until
appropriate tests have been made. A too short or too long delay could reduce the life expectancy
of the filters. Contact your A.Q.C. representative for questions.
18.2 DCT-1000 sequencer
The card programming was set at the factory. The valves opening time was set at 100 msec and the
delay set at 10 seconds. Furthermore, if the electronic card was supplied with a pressure module,
other parameters may be programmed such as low and high pressures, pulse connectors, etc.
Should those delays be modified for any reason, adjust them as per the following instructions:
Press the
"select"
button to scroll the different programming options. Press
"UP"
and
"DOWN"
buttons to modify the value.
1.
"LAST OUTPUT"
sets the amount of valves the system uses.
2.
"TIME OFF"
sets the delay in between each pulse.
3.
"TIME ON"
sets the valve opening time.
4 .
"HIGH LIMIT"
sets the highest limit at which the sequencer will start pulsing (available only
with the DCP pressure module).
5 . "LOW LIMIT"
sets the lowest limit at which the sequencer will stop pulsing (available only
with the DCP pressure module).
6.
"HIGH ALARM"
and
"LOW ALARM"
are adjustments for an alarm signal to be activated if
either of the two (2) settings is passed.
7.
"CYCLE DELAY"
allows a waiting period between each cleaning cycle.

"DOWN TIME CYCLE"
allows one or more cleaning cycles after the shutdown of the system.
9.
"AUTO ALARM RESET"
allows the original automatic alarm settings.
Refer to the manufacturer’s owner’s manual for any questions concerning the DCT-1000 sequencer.
Note:
Do not readjust the valves opening time
"PULSE ON"
or the delay between each cleaning until
appropriate tests have been made. A too short or too long delay could reduce the life expectancy
of the filters. Contact your A.Q.C. representative for questions.
