  • Page 7: General Information

    1.2. Description 1.2.1. General The PN-150BE relay is a high efficiency biased relay which will respond to very low currents. The coils of this relay may be externally connected in series or multiple to suit the particular application. This characteristic permits it to be used in series with another relay, in applications where low currents must be employed to keep voltage loss to a minimum, or with "UT"...

    *** For use with "UT" Timing Units. These relays are presently furnished with a Lexan cover. When the present stock of TYRIL covers is depleted, all PN-150BE covers will be Lexan with molded-in vent. Contacts - standard low voltage silver to silver-impregnated carbon front, and silver to silver back.

    PN-150BE Biased High Efficiency Vital Relay #20 (3680195), two #14 - #16 (3680195-0001), or two #10 - #12 (3680195-0002) wires. Make certain which type of solderless receptacles contact springs accompany the mounting base before proceeding with their installation. Each solderless receptacle contact spring should be inspected for physical damage before proceeding with installation.

    PN-150BE Biased High Efficiency Vital Relay SHOP MAINTENANCE 4.1. Introduction This section provides the information necessary to perform shop level repairs of the PN- 150BE relays covered in this manual. In general, relays arriving at the shop for repair have been checked in the field and have been found to perform unacceptably or have been physically damaged.

    PN-150BE Biased High Efficiency Vital Relay SAFETY PINS SEE ENLARGED AREA STOP PIN Figure 4-1. Armature Stop Pin Location b. Insert the impregnated strip between the armature stop pin and its point of contact on the relay pole face. While applying moderate pressure to keep the armature closed, pull the strip back and forth in a circular motion and continue for several seconds to ensure a sufficient amount of graphite transfer.

  • Page 21: Performance Test

    PN-150BE Biased High Efficiency Vital Relay NOTE In the final cleaning procedures outlined in the following sections, it is recommended that all silver contacts be cleaned first and then all silver impregnated carbon contacts in order not to contaminate the silver tips with residue that might adhere to the cleaning strips from cleaning the silver impregnated carbon contacts.

  • Page 22: Repairs And Replacement

    PN-150BE Biased High Efficiency Vital Relay 4.4. REPAIRS AND REPLACEMENT Since the contacts are the wearing parts in this relay, in most cases the relay can be restored to proper operation by dressing (Section 4.2.2.2) and readjusting (Section 4.5.5) them.

  • Page 23: Adjustments

    PN-150BE Biased High Efficiency Vital Relay Replacement contact blocks MUST be of the same general design. Carefully install the dowel pins, tapping in until they are flush with the aluminum surface. If it is necessary to install a used contact block from another relay, remove only one of the dowel pins from the aluminum frame.

    PN-150BE Biased High Efficiency Vital Relay Twist Drill - #42 Gram Gauge - 250 Grams Screw Driver - Torque Measuring 4.5.2. Magnet and Magnet Extension Insert a 0.117 inch spacer between the stop pin and the pole face and adjust the permanent magnet extension so that it touches the Teflon back stop tape or the back stop pins, whichever is present on the bottom of the armature.
  • Page 25 PN-150BE Biased High Efficiency Vital Relay Contact surfaces should not be disturbed unless there is evidence of severe pitting from excessive loading or an accidental short through the contacts. In case contacts must be dressed, nothing coarser than a #6 pillar file should be used and this should be followed by the use of Metallographic paper to remove file marks.
