Page 3: Introduction
In the LLO (to fill a tank) position, relay K1 energizes when the low level limit is tripped and then deenergizes when the high level limit is reached. In the event of power failure with the relay energized, the PP10 unit will revert back to proper operation after one cycle of the level limit switches. -
Page 4: Mounting
2.0 Mounting The IR10 and PP10 units are generally mounted in an explosion proof enclosure using two 6-32 screws and standoffs. The standoffs are required between the circuit board and enclosure. The units can be mounted in other enclosures, if required. -
Page 5: Maintenance
3.0 Maintenance The IR10 and PP10 require minimal routine maintenance in normal day to day operation. Before inspection, the device must be de-energized an locked out of service. Failure to do so could lead to personal injury or death, as a result of shock. -
Page 6: Applications
They can also be used to provide adjustable deadband (hysteresis) for alarms and other control applica- tions. The following diagrams should help provide applications information on how to utilize the IR10 or PP10. It is assumed that ABB latching level switches are used in all of the following application diagrams. Please not that the deadband (hysteresis) of the limit switches shown may be so small that the controlled device will cycle (on-off) more than desired. -

This circuit, for example, could be used for pumping fluid into a tank. If the PP10 were set to HLO (pumping down), the motor would then energize when the high level limit is tripped and then deenergize when the low level limit is tripped. -
Page 8: Appendix
5.0 Appendix - Reed Switch Protection Many of ABB’s switch products (MS30, MS30/EX, MS50) are based on magnetically operated reed switches. Since reed switches have the inherent characteristic of very closely spaced switch contacts, it is extremely important to protect these contacts from high voltage transients caused by inductive loads. When an inductive load is deener- gized, the collapsing magnetic field induces a high voltage of opposite polarity into itself and thus the switch. -
