The OS3 oil-sensing sump system is designed and approved for the
safe pumping, alarming, and monitoring of elevator sump pits, trans
-
former vaults, and leachate wells. The OS3 will activate a pump to
remove water from elevator pits in accordance with ASME A17.1.
Indicator lights will illuminate on the control panel for power, pump
running, high alarm, high oil, and pump overload (optional). 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 water and
oil and activate the remote alarm.
