7. Move back to the “Bar Monitor Set-Up” pot, slowly turn the pot to move the “Bar
Performance” indicator light down the grid display until it approaches the base of
the normal range on the grid and the SERVICE light illuminates. At this point,
slowly turn the pot in the opposite direction until the SERVICE light extinguishes,
then continue for 1/8 turn.
8. The calibration is now completed.
Other Display Lights on the True AC Monitoring Power Supply
Local/Remote Switch
– Set the switch in local mode unless connecting a voltage signal
from 12 to 24V, 1A max. for remote on/off operation to the remote connections located
adjacent to the AC power switch. Contact Simco-Ion for instructions on how to connect
for remote operation.
Bar Off
– Will only illuminate when operating in remote mode and the power supply
is remotely turned off.
Bar On
– Will illuminate when there is AC line power to the power supply in either
local or remote mode.
Fault
– Indicates that there is a malfunction in the bar or power supply.
Clean Bar
- Indicates that the static bar needs to be cleaned. The “Clean Bar” light
on the Power Supply accompanying these instructions is set to illuminate when the bar
efficiency falls to 40%. This set point is adjustable in the field, as described above.
Service
– Will illuminate when either the ionization is terminated, or there is an
electrical restriction that affects the high voltage to the static bar.
Cleaning Instructions
Clean the face of the bar (the surface with emitter points) using a brush with stiff, non-
metallic (e.g., nylon) bristles. This will often bring the bar’s efficiency back to or near
100%. If it does not, there may be an accumulation of contamination on the sides or
back of the bar. Vigorously clean the sides and back using a brush or cloth and isopropyl
alcohol and/or a mild detergent like Dawn dish washing detergent.
Do not re-energize the bar until it is dry.
