Collector Wiring

Input

102-132V/50-60Hz/1Ph
Output Solenoids

2-3A max per channel
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, the OFF time must be field adjusted

such that the pressure at the air reservoir peaks at 8-9 psig

just before the next pulse. Make final adjustments by observing

the LOAD ON light flashing on the timer.

Open the valve to the air

reservoir gauge only when

adjusting OFF time.

Operating Temperature Range

-20° F to 130° F
Solenoid Valves

120V/60 Hz intermittent duty @ 20.9 watts
Interlocking

To ensure proper operation of the system the main blower

should not start unless the cleaning mechanism, positive-

displacement blower, and dust removal system are all

operating. It is recommended that an interlock device is

installed between these motors. Failure of interlocked devices

should generally not shut down the main blower, but should

activate an alarm system, if available. Failure of either a rotary

airlock or screw conveyor with separate drives should shut

down all other drives and alarm the operator. This will avoid

filling the collector with dust.

Time Delay, Start-Up

Starting motors at 3-second intervals is recommended to

minimize inrush current and to allow interlocking.
Time Delay, Shut-Down

A sequenced shut down approach is recommended for optimal

performance of the collector. After the main blower shuts

down, the remaining components should continue to run for

several minutes to empty the hopper and dust removal system

of all dust that drops from the filter bags after the primary

airflow stops.
