Description
The K-TEK PP10 Latching Relay Controller is designed for use in applications requiring control of on / off devices such as motors, motor starters, solenoids and alarms. The Pump-Pak is a control device consisting of a PC board mounted relay and associated components. The PP10 is supplied in an explosion proof enclosure (Class 1, Division 1) and is available with an optional mounting hardware kit. The PP10 is generally powered by 120 VAC, however, other operating voltages are available. The PP10 accepts two sets of contact inputs and provides a dry contact input (NO and NC contacts). The PP10 operates as a simple start / stop control circuit, actuated by external limit switches. High or low level operation is selected via a miniature switch located on the circuit board. The on-board relay operates as follows: In the HLO (to empty a tank) position, relay K1 energizes when the high level limit is tripped and then deenergizes when the low level limit is reached. 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.
