Donaldson Company, Inc.
(external mounted controls only)
The collector is equipped with 115-Volt solenoid valves to
control the pulse-cleaning valves, which clean the filters.
Weatherproof NEMA 4 enclosures with 3D2 solenoids or
explosion proof NEMA 9 enclosures with 5D2 solenoids
are mounted near the collector’s compressed-air
manifold.
If external remote-mounted controls were selected,
connect solenoids to the solid-state timer following
the wiring diagram supplied with the collector. Wire
the solenoids so that pulsing occurs in a top to bottom
fashion. Filter life and cleaning operation will be affected
if not wired correctly.
Timer and Solenoid Specifications
Input
105-135V/50-60Hz/1Ph
Pulse ON Time
Factory set at 100-milliseconds, or 1/10-second.
Do not adjust pulse ON time
unless the proper test equipment
is available. Too much or too little ON time can
cause shortened filter life.
Pulse OFF Time
Factory set at 10-seconds.
Operating Temperature Range
-20° F to 130° F
Transient Voltage Protection
50 kW transient volts for 20-millisecond duration once
every 20 seconds, 1% duty cycle.
Solenoid Valves
115-Volt at 19.7 watts each
Compressed-Air
Set compressed-air supply at 90-psig. The timer is factory
set to pulse one valve every 10-seconds when pulsing is
activated on the TG2 through TG8, and two valves on the
TG12.
Do not increase supply pressure
above 100-psig. Component
damage can occur.
All electrical wiring and connections, including electrical
grounding, should be made in accordance with the
National Electric Code (NFPA No. 70-latest edition).
Check local ordinances for additional requirements that
apply.
The appropriate wiring schematic and electrical rating
must be used. See collector’s rating plate for required
voltage.
An electric disconnect switch having adequate amp
capacity shall be installed in accordance with Part IX,
Article 430 of the National Electrical Code (NFPA No.
70-latest edition). Check collector’s rating plate for
voltage and amperage ratings.
Refer to the wiring diagram for the number of wires
required for main power wiring and remote wiring.
Electrical installation, service,
or maintenance work must
be performed by a qualified electrician and
comply with all applicable national and local
codes.
Turn power off and lock out all power before
performing service or maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
