OWNER'S MANUAL
OA1S Series Oil Sensing Unit
The Oil/Water Detection control sump system is designed and approved to
safely operate pumps and monitor elevator sump pits, transformer vaults,
and leachate wells. It will activate a pump to remove water from elevator
pits in accordance with ASME A17.1 / CSA B44.
Indicator lights will illuminate on the control panel for power, pump run-
ning, high alarm, high oil, and pump overload (optional). Green LEDs indi-
cate Power and Pump Run. Red LEDs indicate alarms, activated sensors, or
system settings. The panel has a set of auxiliary contacts that activate on
power loss or high oil/water conditions. If the liquid level reaches the alarm
probe and high-level float, the system will differentiate between OA1S
water and oil and activate the remote alarm.
