AVS 800-372-7402控制模塊
要計算功率需求：
（1） 在列中輸入系統中使用的每種類型的設備數量B
（2） 乘以C列所示的單位功率。
（3） 在D列中輸入結果。
（4） 將D列相加，計算所需的總功率。
通風系統57控制系統為大量
通道在非常小的空間中。在人口密集的機架中，尤其是配置有許多催化輸入控制卡或繼電器的
正常通電運行時，散熱可能：導致機架內和區域內的溫度顯著升高靠近機架。
因此，必須仔細考慮熱規劃。到實現最大程度的對流冷卻，始終確保空氣能夠通過機架和電源自由流動。不要堵塞通風口機架頂部和底部的孔，如有可能，將控件隔開卡片均勻地放在架子上。
建議在調試期間，工作溫度：檢查機架的溫度，以確保最高工作溫度不超過55°C。在某些情況下，添加強制空氣可能需要通風。
允許的最大電源配置，不提供：
8路機柜的附加通風為100w，16路機柜的額外通風為200w內閣
預備確保每個控制卡與建議的傳感器兼容/與該控制卡相連的變送器。
確保在使用交流至直流電源裝置的情況下，這是與本地市電交流電源電壓兼容，且PSU額定功率足以滿足其單獨的系統負載。
注：05701-A-0405和05701-A-0406型交流至直流電源供電單元運行，無需輸入電壓
從85V到264V、47Hz到440Hz交流電源的調整輸入。
機柜安裝
可提供兩個機柜，一個8向機柜可容納8向機柜訪問機架和16路，以容納16路前訪問支架
機柜必須固定在墻上或其他合適的垂直位置表面，如下所示：
（1） 根據需要敲出底部壓蓋板入口安裝機柜前，系統布線并安裝密封套。
（2） 將提供的四個安裝支架連接到機柜。
（3） 使用所示尺寸標記支座的位置安裝表面上的孔。
（4） 如有必要，鉆孔并堵上安裝孔。
To calculate the power requirement:
(1) Enter the number of devices of each type used in the system in column
B.
(2) Multiply by the unit power shown in column C.
(3) Enter the result in column D.
(4) Add up column D to calculate the total power required.
VENTILATION
The System 57 Control System provides the facility for a large number of
channels in a very small space. In heavily populated racks, especially
those with many catalytic input control cards or relays configured for
normally energised operation, it is possible for the heat dissipation to
cause a significant rise in temperature both within the rack and in an area
close to the rack.
As such, careful consideration must be given to thermal planning. To
achieve most from the convection cooling, always ensure that the air can
flow freely through the rack and power supply. Do not obstruct the air vent
holes in the top and bottom of the rack and if possible space the control
cards evenly within the rack.
It is recommended that during commissioning the operating temperature
of the rack is checked to ensure that the maximum operating temperature
of 55°C is not exceeded. In some cases the addition of forced air
ventilation may be required.
Maximum power supply configuration allowed without provision for
additional ventilation is 100w for 8 way cabinet and 200w for 16 way
cabinet.
PRELIMINARIES
Ensure that each control card is compatible with the proposed sensor/
transmitter to be connected to that control card.
Ensure that where an AC to DC Power Supply Unit is to be used, this is
compatible with the local mains ac supply voltage and that the PSU
power rating is adequate for its individual system load.
Note: The model 05701-A-0405 and 05701-A-0406 AC to DC Power
Supply Units operate, without the requirement of input voltage
adjustments, from an 85V to 264V, 47Hz to 440Hz ac supply
inputs.
CABINET INSTALLATION
Two cabinets are available, an 8-way to accommodate the 8-way front
access rack and a 16-way to accommodate the 16-way front access
rack.
The cabinet must be secured to a wall, or other suitable vertical
surface, as follows:
(1) Knock out the bottom gland-plate entries as appropriate for the
system cabling and fit the glands before mounting the cabinet.
(2) Attach the four mounting brackets provided to the cabinet.
(3) Using the dimensions shown mark the position of the mounting
holes on the mounting surface.
(4) Drill and wall plug the mounting holes as necessary.
