DUST COLLECTOR CONTROLS
AC Input, Pulse Cleaning of
Bag House Dust Collectors
Models DNC-T2003 through DNC-T2032
FEATURES
Digital Timing Circuitry: allows for sta-
ble timing from -40°C to 65°C tempera-
ture range
Pulse Time: line synchronized to elimi-
nate 8 millisecond triac turn off variation
10 A-400/600V Output Triacs: for maxi-
mum protection against output shorts.
200 VA load rating
Conformally coated for protection
against vibration, humidity, and con-
tamination
2 Modes of Operation: can be operated
Continuously or On Demand via external
pressure switch
Field Selectable: for numbers of outputs
required
LED Indicators: for compartment being
cleaned indication
Rugged Timing Adjustments: large sta-
ble potentiometers are used for ON and
OFF time adjustments
Metal Chassis Provided: for mounting
directly into NEMA 4 box
Timer Functionally Tested for 24
Hours: to eliminate field failures
Input Protection: 30 joule metal oxide
varistor
One Year Warranty: warranted to be free
from defects in materials or workmanship
for one year from date of manufacture
File #E65038
Operating Logic: The control can function
in 2 modes.
In Continuous Mode, the pressure switch
terminals are shorted. Upon application of
input voltage, the control activates output
#1 after the preset off time. It will continue
to activate outputs sequentially until input
voltage is removed.
In On Demand Mode, the pressure switch
terminals are connected to an isolated set
of contacts of a differential pressure switch.
The control will activate the outputs sequen-
tially whenever the pressure switch contacts
are closed. When the pressure switch con-
tacts open, the output sequencing stops.
Re-closing of the contacts will cause the
control to resume activating the outputs.
Program wire allows the user to select the
maximum number of outputs to be acti-
vated.
Note: Controls are shipped with jumper across pressure switch
terminals
