User manual KIRK KEY SOLENOID AND TIME DELAY KEY RELEASE UNITS

[. . . ] After installation of the interlocks, the complete interlock system should be tested sequentially by person(s) familiar with the entire system and its intended purpose. Any problems or discrepancies must be corrected prior to energization. Each interlock is supplied with a key in each cylinder. These keys are needed during installation of the interlocks.

IB/KRU/06 CUSTOMER TO WIRE THIS SIDE ONLY PAGE 4 Instruction Manual for: Solenoid Key Release Unit and Time Delay Key Release Unit KIRK ® Time Delay Key Release Unit (Type TDKRU) The TDKRU is comprised of two key interlocks, a timing device, a solenoid, and an indicating light. The unit is available housed in an aluminum enclosure or unhoused with front cover only. All electrical components are wired out to a terminal block. See the wiring diagram on page 6. HELD KEY INITIATING KEY The TDKRU is a two key device. The secondary key is held in the unit until the initiating key is inserted and turned starting the time delay sequence. The initiating key will come from an interlock on the equipment being de-energized (such as a capacitor bank or rotating equipment). Inserting and rotating the initiating key begins the time delay sequence. After the predetermined delay, the indicating light illuminates permitting the secondary key to be turned and released thereby trapping the initiating key in the TDKRU. The secondary key can now be safely utilized on related key interlocked equipment (such as a ground switch or access door).
