UNS2882A 3BHE003855R0001電路板將一個或兩個輸出置于斜坡模式，并設置斜坡特性。在斷電期間，不會保留對模塊的這些更改。如果模塊通電，新命令必須發(fā)送至模塊，以再次修改配置的報警限值，或為設置斜坡操作輸出。危險區(qū)域安裝以下信息適用于帶有UL危險區(qū)域標記或ATEX標記的產品對于爆炸性環(huán)境：? 標有I類A、B、C和D組2類危險區(qū)域的設備僅適用于I類2類A、B、C、D組或非危險場所? 警告-爆炸危險-更換部件可能會影響I級的適用性，第2部分；? 警告-爆炸危險-在危險位置時，請在更換前關閉電源或接線模塊；和? 警告-爆炸危險-除非有電源，否則不要連接或斷開設備已關閉或已知該區(qū)域無危險。
Changing Module Operation on Command
The ALG442 can respond directly to a specific COMM_REQ command from the application program to:
? clear the module’s %I error code
? modify the Input alarm limits, and
? put one or both outputs in Ramp mode and set up the ramp characteristics
The Task input to the COMM_REQ function must be zero.
COMM_REQ Format
Module ALG442 can respond directly to a specific COMM_REQ (Communication Request) command from the
application program to:
1. Clear the module’s %I error code.
2. Modify the Input alarm limits, and.
3. Put one or both outputs in Ramp mode and set up the ramp characteristics.
These changes to module are not retained during loss of power. If the module is power-cycled, new commands
must be sent to the module to again modify the configured alarm limits, or to set up Ramp operation for the
outputs.Installation in Hazardous Areas
The following information is for products bearing the UL marking for Hazardous Areas or ATEX marking
for explosive atmospheres:
? EQUIPMENT LABELED WITH REFERENCE TO CLASS I, GROUPS A, B, C & D, DIV. 2 HAZARDOUS AREAS IS
SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C, D OR NON-HAZARDOUS LOCATIONS ONLY
? WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I,
DIVISION 2;
? WARNING - EXPLOSION HAZARD - WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING
OR WIRING MODULES; AND
? WARNING - EXPLOSION HAZARD - DO NOT CONNECT OR DISCONNECT EQUIPMENT UNLESS POWER HAS
BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS.
