The Aerostat PC2 leaves the factory with the Balance Adjust Control set to meet
performance specifications during the final factory test. For optimal performance, it
is recommended that the PC2 balance setting be checked and adjusted (if required)
by the end-user prior to using the Blower. A Charged Plate Monitor (CPM) with a
standard 6" x 6" plate, such as the Simco-Ion Model 280A, is required to monitor
the balance of the ionizer during the balance adjustment procedure.
NOTE
– It is recommended that the PC2 be allowed to run and acclimatize for
an initial 12-24 hours in an environment comparable to the application area
before any performance measurements are conducted.
1. Set the PC2 fan to the desired speed.
2. Place a Charged Plate Monitor at a distance of about 12" (300 mm) directly in
front of the blower with the CPM plate positioned in the ionized air stream.
Turn on the CPM and set it for balance monitoring. Observe the balance
reading displayed by the CPM.
3. Use a trimpot tool or small flat blade screwdriver to adjust the "Balance" control
on the rear panel of the PC2. Turning the balance adjust control clockwise will
make the balance voltage more positive. Turning the control counterclockwise
will make the balance more negative.
The PC2 should be adjusted so that the CPM displays a balance of about 0V +/-5V.
NOTE
– For PC2 with heater option, it is important to re-balance the unit by
adjusting the trimpot clockwise or counterclockwise when the heater is turned
ON or OFF to achieve the specification performance.
Simco-Ion recommends using the built-in brush emitter point cleaner daily
for optimum balance performance. This will ensure that the Aerostat PC2
provides the best decay and balance performance to your target area.
The Aerostat PC2 Blower should be OFF when using the emitter point
cleaner. Do not clean the emitter points while the Blower is operating.
Alarms
An alarm condition may be caused by any of the following:
• No power to the fan unit
• The fan in locked-rotor condition or fan failed
• Failed high voltage power supply
• Extremely dirty emitter points (possible)
If you have ordered the Aerostat PC2 with an audible alarm, the audible alarm will
sound upon any alarm condition.
