Overview:
The SnoGun
tm
Power Supply/Timer (SG-PST-III) will supply timing pulses to
the SG-2A-24DC Automated SnoGun
tm
as programmed by the operator. The
circuit is programmed to operate in five "Run" modes: One-Shot, Repeat Cycle,
Counted Repeat Cycle, Toggle, and Direct. Two "Purge" modes, Timed or
Continuous, are also available. The SG-PST-III is programmed using the
display on the front panel. "On" and "Off" times may be independently chosen
from 0.01sec to 99.99 seconds each. The footswitch and "Trigger" switch serve
the same purpose.
