Control system for recoil simulator.

摘要

The recoil simulator control system is designed especially for controlling the rotation direction of reversible engines. It cooperates with two limit switches, controlled by the reversible engine. Characterized in that: The contactors (1 and 2) constitute the outputs of its two branches. The inputs of the contactors receive signals from normally opened (NO) outputs of the relays (3 and 4). These signals are also transmitted to the inputs of the relays (3 and 4), which also receive the control signals from the normally opened outputs of the input relays (5 and 6). The normally closed (NZ) output of the input relay (5) of the first branch is in the blockade (B) circuit of the relay (4) of the second branch. The normally closed output of the input relay (6) of the second branch is in the blockade circuit of the relay (3) of the first branch. The blockade circuit of the relay (3) of the first branch contains the normally-closed contacts of the first limit switch (PK1). The blockade circuit of the relay (4) of the second branch contains the normally-opened contacts of the second limit switch (PK2). The blockade circuit of the input relay (5) of the first branch contains the normally-closed contacts of the second limit switch (PK2). The normally opened contacts of the first limit switch (PK1) are connected into the input circuit of the input relay (6) of the second branch.
