    ? 僅當操作員激活啟用開關及時識別危險情況,以便可以立即采取必要措施避免此類情況!

    ? 啟用開關僅用于啟用執行以下操作的命令:危險的運動。命令本身必須被激活

    通過單獨的操作元件(HT上的鍵)。只有以下人員:允許激活啟用開關,也允許在這是一個危險的地區。

    ? 2位啟用開關只能與緊急停止設施。

    ? 在HT 40X上,啟用開關始終具有2個通道。能夠評估在以下方面應遵守哪些規則或規則的哪些部分:機器的安全相關部件,可進行風險評估。

    2.4機械風險評估對于風險評估,必須采用以下標準:

    ? EN 292“機械設計的一般原則”

    ? EN 1050“機械風險評估原則”

    ? EN 954-1“控制系統的安全相關部件”

    安全類別(B、1、2、3、4)最終定義了此風險評估的機器結果。

    以下接線圖顯示了如何使用KEBA實現安全等級3

    手持終端及其安全相關部件。機器的整個概念必須是:根據安全類別3的原則制定。功能程序:

    僅當兩個啟用開關ZT1和ZT2“同時”激活兩個輸出繼電器K1時并且K2將通電并且輸出觸點13-14和23-24將閉合。如果出現以下情況,輸出繼電器K1和K2將不會通電:

    ?僅激活一個啟用開關,

    ?超過同時期,

    ?反饋控制回路X1-X2開路。

    如果啟用開關在同時激活后被釋放,則輸出繼電器K1和K2將再次斷電。強制引導輸出觸點13-14和23-24將斷開。輸出只有在兩個啟用開關同時釋放后,繼電器才會再次通電再次操作。

    通過這種方式,使能開關滿足要求,即避免一個單一錯誤

    使安全功能不可操作。最遲將在下一個周期識別單個錯誤。

    ? Enabling switches may only be used if the operator activating the

    enabling switch recognizes the dangerous situation in time so that he

    can immediately take the necessary measures to avoid such situations!

    ? The enabling switch is only used to enable commands for performing

    dangerous movements. The commands themselves must be activated

    by a separate operating element (key on HT). Only persons who are

    allowed to activate the enabling switch are also allowed to work in the

    dangerous area.

    ? 2-position enabling switches may only be used in connection with an

    emergency stop facility.

    ? At the HT 40X, the enabling switches always feature 2 channels.

    To be able to assess what rules or what parts of the rules are to be observed regarding the

    safety-related parts of a machine, the risk assessment can be carried out.

    2.4 Risk Assessment of Machinery

    For the risk assessment the following standards must be applied:

    ? EN 292 ?General principles for design of machinery“

    ? EN 1050 ?Principles for risk assessment of machinery“

    ? EN 954-1 ?Safety-related parts of control systems“

    The safety categories (B, 1, 2, 3, 4) which finally define the structure of safety-related parts of

    a machine result from this risk assessment.

    The following wiring diagram shows how the safety category 3 can be fulfilled with KEBA's

    handheld terminals and their safety-related parts. The entire concept of the machine must be

    laid out according to the principles of safety category 3.Functional procedure:

     Only if both enabling switches ZT1 and ZT2 are activated ?simultaneously“ both output relays K1

    and K2 will energise and the output contacts 13-14 and 23-24 will close.

     The output relays K1 and K2 will not energise if

    ? only one enabling switch is activated,

    ? the simultaneity period is exceeded,

    ? the feedback control loop X1-X2 is open.

     If an enabling switch is released after being simultaneously activated, the output relays K1 and K2

    will de-energise again. The forced-guided output contacts 13-14 and 23-24 will open. The output

    relays will energise again only after both enabling switches have been released and simultaneously

    operated once again.

    In this way the enabling switches meet the requirement which consists in avoiding that one single error

    makes the safety function inoperational. A single error will be recognized at the next cycle at the latest.
