UR6AV綜合保護繼電器
將16路交流至直流電源裝置升級至150W，或200W進行如下操作：
（1） 安裝第二個50W子單元，包含50W切換模式模塊，連接至16路交流至直流電源裝置前面板使用提供的固定件。
（2） 當需要升級到200W時，再安裝一個50W開關如第17.2節所示，將模式模塊插入新的50W子單元。
警告系統電源處可能存在高交流電源電壓單元和接口卡的繼電器端子。適當的調試或維修時必須采取安全預防措施系統。
重要的應進行系統的調試和維護僅由經過培訓的授權人員執行。
1.概述
以下調試和維護指南應：與發布的相關說明一起使用正在使用傳感器。
以下信息適用于使用單個直流輸入卡的電源連接。有關
每個單獨通道通電的系統，請聯系Zellweger Analytics。
（6） 關閉電源。
（7） 將接線盒TB1重新連接至直流輸入卡。
（8） 打開系統電源。
（9） 檢查是否仍存在18V和32V直流電壓之間的電壓接線盒TB1。
（10） 檢查工程卡前面板上的電源（）是否為綠色LED點亮，解鎖（）LED閃爍。
（11） 將插槽1中的控制卡完全推入機架，使其與背板連接，并用兩個固定件固定螺釘。
（12） 檢查顯示器是否工作，以及控制卡前面板點亮。
（13） 檢查在預定義的啟動禁止期后，通常為30秒，禁止LED熄滅。
To upgrade the 16-Way AC to DC Power Supply Unit to 150W or
200W proceed as follows:
(1) Fit a second 50W Sub unit, containing a 50W Switched Mode
Module, to the 16-way AC to DC Power Supply Unit front panel
using the fixings supplied.
(2) When an upgrade to 200W is required, fit a further 50W Switched
Mode Module into the new 50W Sub unit as indicated in Section 17.2.
WARNING
High ac mains voltages may be present at the system power supply
unit and at the relay terminals of the interface cards. Appropriate
safety precautions must be taken when commissioning or servicing
the system.
IMPORTANT
Commissioning and maintenance of the system should be carried out
by trained authorised personnel only.
1. GENERAL
The following guide to commissioning and maintenance should be
used in conjunction with the relevant instructions issued with the
sensors being used.
The following information applies to the setup of a system with a single
power supply connection to the DC Input Card. For information on
systems where power is applied to each individual channel, please
contact Zellweger Analytics.
(6) Switch off the power supply.
(7) Reconnect the terminal block TB1 to the DC Input Card.
(8) Switch on the system power supply.
(9) Check that a voltage of between 18V and 32V dc still exists at the
terminal block TB1.
(10) Check that the Engineering Card front panel power on ( ) green
LED is illuminated and the unlocked ( ) LED is flashing.
(11) Push the control card in slot 1 fully into the rack so that it makes
connection with the backplane and secure with the two securing
screws.
(12) Check that the display operates and that the INHIBIT LED on the
control card front panel is illuminated.
(13) Check that after the pre-defined start up inhibit period, typically 30
seconds, the INHIBIT LED is extinguished.
