Definitions

  • the invention relates to a circuit arrangement to supervise an m-out-of-n code in which arrangement a code relay is provided for each of the n-code elements.
  • embodiments of the invention employing (m+1) contact multiples, formed by the make-contacts of the code relays.
  • the make-sides of all contacts, except those of the input contact multiple are decoupled through rectifiers, and the make-sides of the input contact multiple are connected to the control potential and the output of the output contact multiple is connected with the control winding of an alarm relay.
  • make-contacts are especially valuable for circuitry techniques using reed contact relays.
  • all supervising functions can be obtained, such as the indication of completeness and an alarm in case of excessive determination or incomplete determination of the code.
  • FIGS. 1 to 5 show examples for an m-out-of-6 code and FIG. 6 shows an arrangement of code relays.
  • FIGS. 1 to 5 are subdivided into blocks A, B, C.
  • Block A shows the contact arrangement as far as it serves to determine an excessive definition of the code.
  • Each contact multiple contains (n-m) contacts and starts, always staggered by one contact.
  • the first multiple contains the three contacts 1, 2, 3, the second multiple the contacts 2, 3, 4, the third multiple the contacts 3, 4, 5, and the last multiple [(m+1)te] the contacts 4, 5, 6.
  • the contact multiples are always formed by [(n+l)m] contacts, for example, the input contact multiple now contains the contacts 1, 2, 3, and 4; but the output contact multiple remains unchanged.
  • the input contact multiple now contains always one contact of each code relay.
  • FIG. 1 shows the supervision of a 1-out-of-6 code.
  • the input contact multiple EKV contains, in all the illustrated circuit arrangements, 6 contacts (corresponding in the general case of n contacts). This means that a contact from each of the 6 code relays (in the general case N code relays) is present in the input contact-multiple.
  • an alarm relay ALu is connected via a break-contact czZ of relay CR and a make-contact t of a conventional time supervising circuit, not shown on the drawing, in contrast to the circuit arrangement for the l-out-of-6 code. If less than in code elements are given (but never less than 1 code element), the relay CR which is connected to the output of the m-th contact multiple is not energized and, after a predetermined period, the alarm relay ALu is excited.
  • relay CR If m code elements exist relay CR responds, thereby indicating the completeness of the code; the relay CR is held energized via an intrinsic make-contact, arranged between the outputs of the first (EKV) and the m-th contact multiple, until the last code element has been read out, i.e. as long as a code relay is still energized. Processes may depend from this measure which are not in direct connection with the idea of the invention.
  • the excessive code definition is supervised in the way described for FIG. 1.
  • the rectifiers are superfluous in cases where no connections to the following contact multiple exist.
  • (m-l-l) contact multiples including. an input contact multiple and an output contact multiple formed by make contacts of said code relays,
  • rectifier decoupling means including rectifier decoupling means, connected to interconnect contacts of adjacent contact multiples and to allow current flow in one direction through closed contacts,
