Figure 6. Sampling/Sensor Assembly
ALARM LIMIT (PPM) SELECTOR switch A1S2 (figure 6, item 2). This switch is a three-position toggle switch (70
PPM, REMOTE, and 15 PPM positions). Switch A1S2 is used to select the 70 or 15 PPM alarm limits or to enable
the remote alarm limit selector switch. With A1S2 in the 70 PPM position, the OCM will activate alarms and
energize the diverter solenoid valve when the oil content exceeds 70 ppm (+/- 30 ppm). With A1S2 in the 15 PPM
position, the OCM will activate alarms and energize the diverter solenoid valve when the oil content exceeds 15
ppm (+/- 5 ppm). With A1S2 in the REMOTE position, the PUSH TO CHANGE ALARM LIMIT (PPM) pushbutton
switch A2S1 on the remote indicator alarm assembly is engaged, allowing the operator to select the alarm limit
from this remote location.
