In addition, the contact block models that should be used are given; model VA0 (or FA0 for contact No. 1, to be installed in the upper contact block location; model V40 (or F40) for contact No. 2, to be installed in the lower 1. Determine how many contacts are required for the application, and what contact closure sequence is needed for each contact. a. 2-Position Operators: There are only two practical possibilities for contact closure sequence. 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 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 cam types are available to provide various combinations of contact closure sequence. Cam Type 2 (see table below) provides the most popular closure sequence, and Cam Type 3 provides all six possibilities, depending on the contact block models chosen. Note that each operator has an upper and lower contact block location, and that the cam profiles are different for upper and lower locations, except for Cam Type 2. 2. Make a truth table similar to that shown in the example at the bottom of the page, in which each contact required by the circuit of the application is represented. Up to 12 contacts may be used for each operator, depending on the sequences required and the types of contact blocks chosen. 3. Refer to the contact sequence table (below). Find the cam type that will provide all of the required contact closure 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. CONTACT CLOSURE SEQUENCE CHART 0 1 V40 or F40 Red X 0 V50 or F50 Green 0 X VA0 or FA0 Yellow 0 X* VR0 or FR0 Black X 0* Contact Blocks 2-Position Operators CAM Type 1 Model upper & lower locations Example: An "Off-On-Reset" circuit control requires a 3-position or 2-position keylock switch. The key is to be removable in the "OFF" and "ON" position and the "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 in the "on" position must open. This contact closure sequence is shown by the following truth table: contact block location; and model V50 (or F50) for contact No. 3, which may be used in either the upper or lower contact block location, behind one of the other two blocks. Reference to the operator model listings shows that model RM272 provides cam Type 3 and has desired momentary action and key removability. SELECTOR & KEYLOCK OPERATORS ALCOSWITCH selector and keylock operators, in combination with the contact blocks listed on page I8, are designed to fulfill the circuit requirements of almost any 2- or 3- 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 and the contact closure sequences required. (Note: only one logic level block may be used in each location.) blocks in upper position blocks in lower position 3 Position Operators 20 1 left center right OO X XO O OX X XX O O XO X OX 2 Position Operators 01 left right OX XO X = Closed 0 = Open *VA0 and FA0 contacts overlap with VR0 and FR0 contacts between position of 2 position operators providing “Make Before Break” action. 20 1 20 1 20 1 20 1 2 01 20 1 X 0 0 X0 0 X 0 0 0X 0 0 X X X X0 00 X 00 X 00 X 00 X X 00 00 X 0 X X 0 X X 0X X X0 X X0 0 0 0 X XX 0 XX 0 XX 0 XX 0 0 XX XX 0 3-Position Operators CAM Type 2 CAM Type 3 CAM Type 4 upper lower upper lower upper lower location location location location location location |
