CONTROLS AND INDICATORS (Continued).
Mini-Probe.
Detects presence of oil in prefilter separator.
When mini-probe is covered with oil or is
in air, an electric signal is transmitted
to open prefilter oil discharge valve and
close the water discharge valve.
Sight Glass for Prefilter Separator.
Shows amount of oil in
separator.
Mini-Probe, Second Stage.
Detects presence of oil in separator.
When mini-probe is covered with oil or is
in air, an electric signal is transmitted
to open second stage oil discharge valve.
The second stage mini-probe will override
signals from prefilter stage mini-probe.
Ensures that only one solenoid operated
valve can be open at a given time.
Sight Glass for Second Stage Separator.
Shows amount of oil in
separator.
Solenoid Operated Oil Discharge Valve.
Valve opens when mini-
probe in second stage separator detects oil
and transmits electric signal to valve.
Sight Glass for Third Stage Separator.
Shows amount of oil in
separator.
Oil Discharge Valve.
Manually operated valve for releasing oil
from 3rd stage separator.
Solenoid Operated Water Discharge Valve.
Normally closed (when
solenoid not energized).
Opens to allow dis-
charge of clean water when both mini-probe
are in water.
When either solenoid operated
oil discharge valve opens, the water dis-
chargevalve closes.
Sample/Drain Valve.
Manually operated valve to drain or sample
water in 3rd stage separator.
Intervessel Shutoff Valve.
Manually operated valve to stop flow
of fluid between 2nd and 3rd stage separators.
Sample/Drain Valve.
Manually operated valve to drain or sample
Sample/Drain Valve.
Manually operated valve to drain or sample
water in prefilter separator.
water in 2nd stage separator.
