Marsh Bellofram Diversified Electronics Division SPM-120-AEE Series Submersible Pump Monitor - 1

SPM Series Diversified Electronics atcdiversified.com 800.727.5646 276Special Controls // SPM Series The ATC Diversified Submersible Pump Monitor is a specialized control for monitoring the shaft seal and stator temperature of a submersible pump motor. Seal leakage is detected by either a resistive float switch or a pair of conductive probes installed in the seal cavity. Over-temperature is detected by a normally-closed-low temperature switch mounted on the stator. The over-temperature function incorporates a bistable relay that retains its position during power failures.

800.727.5646 atcdiversified.com Diversified Electronics SPM Series Special Controls // SPM Series 277 \\\WIRING Fig. 1 FLS Connection Figure 1 shows the connections for use with a Flygt model FLS float switch. The leakage sensitivity must be adjusted to 1 k for float switch applications. If a pair of conductive probes is used to sense seal leakage, a 100 k resistor is required as shown in Figure 2, and the sensitivity should be set to the desired value. The states of the unit’s relay outputs are determined by the series combination resistance of the leakage and temperature sensors. Under...
