Such a device must be located outside the dangerous zone, so that the operator cannot enter this zone before the machine has come to a complete standstill. A pneumatic 2-hand control device is composed of 2 parts : 2 manual pushbuttons which require the simultaneous use of both hands. A pneumatic relay. 1 Types of 2-hand control devices Type Requirements I III II A B C Use of both hands (simultaneous actuation) Relationship between input signals and output signal Cessation of the output signal Prevention of accidental operation Prevention of defeat Reinitiation of the output signal Synchronous actuation Use of category 1 (EN 954-1) Use of category 3 (EN 954-1) Use of category 4 (EN 954-1) Category 1 (EN ISO 13849) : the system should use well tried components and principles. Category 3 (EN ISO 13849) : the system must be designed so that a single fault will not cause the loss of the safety function. Category 4 (EN ISO 13849): the system must be designed so that an accumulation of faults must not lead to a loss of the safety function. Synchronous action An output signal is only generated if both control actuating devices are actuated within 500 ms. Resetting the output signal The release of a single control device interrupts the output signal, but a reset is only possible once both control devices have been released. 16 www.crouzet.com Pneumatic relay for two-hand control 100% pneumatic Complies with Machinery Directive and the standard EN 574 +A1 CE Certification type-IIIA and IIIB 81 580 101 III A Pneumatic relay for two-hand control EN 574 +A1 classification 81 580 202 III B Symbol 1 3 1 2 Characteristics Operating pressure Orifice diameter Max. delay between input signals Connection Operating temperature Mechanical life Weight Principle of operation 28 2.5 0.2 max.
