LOGIC FUNCTION DIAGRAM
File #E65038
Operating Logic: The control is used on
intermittent type dust collectors to auto
matically activate the shaking mechanism 2
minutes after the fan motor is turned off.
Upon removing power from the fan, a 2
minute fixed delay is initiated. At the end
of the delay, the shaker output is activated
for an adjustable period of 1.8 seconds to
3 minutes. Resetting the control occurs by
turning the fan motor on again.
CAUTION: The control must be wired according to the schematic
provided.

Caution:
1. Do not mount controls in high vibration areas with
out shock mounts.
2. Do not mount controls in areas of high dust or cor
rosive atmospheres without a protective enclosure.
3 Do not use a converter or inverter for the power
source.
4. Do not mount control in high transient voltage
areas without an isolation transformer
5. Do not leave control box open.
6. Do not allow a local repair shop to repair the con
trols, as we employ some very sophisticated compo
nents that could be further damaged. For service, call
us directly: 800-323-2593
