MVME172-333A模塊備件
選擇電源系統提供四種電源選擇，在任何情況下，機器都會(huì )提供合適的電源。檢查電源參數是否符合規范中給出的墊系統要求。如果使用24V AC或DC電源，則必須根據國際電氣安全慣例（IEC 364-4-41）將其與主電源隔離。一個(gè)極應接地（直流電源負極接地）。如果必須作出特殊安排，則可隨時(shí)提供適合系統的24V DC商用裝置。輔助輸出這是作為狀態(tài)輸出提供的非安全輸出。它在使用PLC功能機器控制和硬接線(xiàn)安全電路作為PLC狀態(tài)輸入的系統中特別有用。其他用途包括保護方案中的診斷和/或驅動(dòng)狀態(tài)燈或警報。安全功能不得依賴(lài)于此輸出。電弧抑制建議所有感應負載使用電弧抑制網(wǎng)絡(luò )或設備。對于安全電路，抑制器應安裝在負載上，而不能安裝在觸點(diǎn)上。抑制器的類(lèi)型和額定值將由電源和負載特性決定。注意，抑制器可以增加響應時(shí)間，特別是直流線(xiàn)圈兩端的抑制器二極管，并且在測量響應時(shí)間時(shí)應安裝到位。
控制單元安全輸出電源至控制單元執行力時(shí)間20ms響應時(shí)間控制單元安全輸入電源至控制裝置重置執行力時(shí)間20m s響應時(shí)間24接觸器監控接觸器監控通過(guò)標記為MC的兩個(gè)端子提供。它應用于所有雙通道雙接觸器系統。如果其中一個(gè)接觸器未能隔離電源，則墊控制單元將鎖定并防止另一個(gè)接觸器重新通電，直到故障得到糾正。5.8最終傳感器墊布局考慮到這些因素后，現在可以檢查并最終確定傳感器墊布局?？紤]機器響應時(shí)間是否與初始計算有所不同。在可能的情況下，應在檢測區的外側邊緣設置墊子和電線(xiàn)。這簡(jiǎn)化了安裝和更換（如果需要），并且所有布線(xiàn)都受到周邊裝飾的保護。5.9布線(xiàn)所有系統布線(xiàn)必須防止機械損壞，并適當密封以適應操作環(huán)境。提供防水對接接頭用于墊子到墊子的連接，并由邊緣鑲邊保護。如果需要在地板上布線(xiàn)，440F-T3230導線(xiàn)導管可以提供適當的保護。其他電線(xiàn)線(xiàn)路應使用導管或線(xiàn)槽?？刂蒲b置的密封完整性必須通過(guò)使用尺寸正確且緊固的導管配件或電纜壓蓋保持在IP65。接線(xiàn)實(shí)踐必須符合EN 60204-1第14條的要求。
The optional power supply system provides four power supply options. In any case, the machine will provide appropriate power supply. Check whether the power supply parameters meet the requirements of the cushion system given in the specification. If 24V AC or DC power supply is used, it must be isolated from the main power supply according to international electrical safety practices (IEC 364-4-41). One pole should be grounded (the negative pole of DC power supply is grounded). If special arrangements must be made, 24V DC commercial devices suitable for the system can be provided at any time. Auxiliary Output This is a non safe output provided as a status output. It is particularly useful in systems that use PLC function machine control and hardwired safety circuits as PLC status inputs. Other uses include diagnostics and/or driving status lights or alarms in the protection scheme. The safety function must not depend on this output. Arc suppression It is recommended that all inductive loads use an arc suppression network or device. For safety circuits, suppressors shall be mounted on the load, not on the contacts. The type and rating of suppressors will be determined by the power supply and load characteristics. Note that the suppressor can increase the response time, especially the suppressor diodes at both ends of the DC coil, and should be installed in place when measuring the response time.
The time from the safe output power of the control unit to the execution force of the control unit is 20ms, and the response time is 20ms. The time from the safe input power of the control unit to the reset execution force of the control device is 20ms. The response time is 24. The contactor monitoring is provided through two terminals marked MC. It is applied to all dual channel and dual contactor systems. If one of the contactors fails to isolate the power supply, the pad control unit will lock and prevent the other contactor from re energizing until the fault is corrected. 5.8 After taking these factors into account, the final sensor pad layout can now be checked and finalized. Consider whether the machine response time is different from the initial calculation. Where possible, mats and wires shall be provided at the outer edge of the detection area. This simplifies installation and replacement, if required, and all wiring is protected by the perimeter trim. 5.9 Wiring All system wiring must be protected from mechanical damage and properly sealed to adapt to the operating environment. Waterproof butt joints shall be provided for the connection of mat to mat, and shall be protected by edge trimming. 440F-T3230 conductor conduit can provide proper protection if wiring is required on the floor. Conduit or trunking shall be used for other wire routes. The sealing integrity of the control unit must be maintained at IP65 by using conduit fittings or cable glands of correct size and fastening. Wiring practices must comply with the requirements of Clause 14 of EN 60204-1.
