Using "O" to indicate an open and "X" to indicate a closed contact, the options are shown in the table to the right. All Reliant OX XO 22 and Series 6000 2-position selection selector and keylock operators provide these options. b. 3-Position Operators: There are six practical possibilities for contact closure sequence. Using "O" to indicate an open contact, and "X" to indicate a closed contact, the options are shown in the table to the right. Four different 3 Position Operators cam types are available to provide various combinations of contact closure sequence. Cam Type 2 (see table 20 1 below) provides the most popular closure sequence, and Cam Type 3 provides all six possibilities, depending on left center right the contact block models chosen. Note that each operator has an upper and lower contact block location, and that OO X the cam profiles are different for upper and lower locations, except for Cam Type 2. XO O 2. Make a truth table similar to that shown in the example at the bottom of the page, in which each contact required OX X by the circuit of the application is represented. Up to 12 contacts may be used for each operator, depending on the XX O sequences required and the types of contact blocks chosen. O XO 3. Refer to the contact sequence table (below). Find the cam type that will provide all of the required contact closure X OX sequences, and note which contact block model will be needed for each circuit contact. 4. Now refer to the tables on pages I5-I6 for 22mm and pages I12-I13 for 30mm to find the operator model that has the cam type needed in the application and that provides the desired features with respect to action (maintained or momentary) type of actuator (lever or key), etc. SELECTOR & KEYLOCK OPERATORS ALCOSWITCH selector and keylock operators, in combination with the contact blocks blocks in listed on page I8, are designed to fulfill the circuit requirements of almost any 2- or 3- upper position position control application. Each operator has two locations (upper and lower) into which contact blocks may be snap-mounted. Up to four contact blocks may be stacked in each location, the maximum number depending on the contact block models chosen blocks in lower and the contact closure sequences required. (Note: only one logic level block may be position used in each location.)

Example: An "Off-On-Reset" circuit control requires a 3-position or 2-position in the "on" position must open. This contact closure sequence is shown by the keylock switch. The key is to be removable in the "OFF" and "ON" position and the following truth table: "Reset" position must be momentary (spring return from right to center). All contacts are open in the "Off" position, and two contacts are closed in the "On" position. In the "Reset" position a third contact must close and one of the contacts Contact Off On Reset Number (2) (0) (1) 1 OXX 2 O X O 3 OOX contact block location; and model V50 (or F50) for contact No. 3, which may be Referring to the Contact Closure Sequence Table, it is seen that cam Type 3 used in either the upper or lower contact block location, behind one of the other two provides these sequences. In addition, the contact block models that should be used blocks.
