壽命根據(jù)差值計(jì)算在第一次測量的靈敏度之間跨度和隨后測量的跨度正常SPAN，并且僅在SPAN函數(shù)。
這是一個(gè)警告，表明傳感器輸出變得不可接受的低，可能到期老化或傳感器“中毒”由于硅酮、硫和鉛化合物。
應(yīng)更換傳感器。信號(hào)低于范圍信息為當(dāng)傳感器信號(hào)讀數(shù)為低于預(yù)定水平信道配置數(shù)據(jù)。這預(yù)定水平低于正常值工作范圍。
這通常是由于傳感器信號(hào)漂移至正常零操作點(diǎn)以下。
這可能取決于傳感器類型，由于氣候的巨大變化狀況、端子連接松動(dòng)、傳感器中毒或早期指示傳感器故障。
在某些情況下，可能會(huì)導(dǎo)致此錯(cuò)誤傳感器或電纜短路。
應(yīng)校準(zhǔn)通道卡，并其操作已檢查信號(hào)超出范圍警告消息為當(dāng)傳感器信號(hào)讀數(shù)為超過預(yù)定水平通道配置數(shù)據(jù)。這預(yù)定水平高于操作水平范圍這些操作說明是指可用于一般用途的設(shè)施無工程密鑰的系統(tǒng)操作和查詢已安裝?？赡苡绊懴到y(tǒng)運(yùn)行方式的設(shè)施包含在工程師操作說明第7章，涉及設(shè)施安裝工程鍵時(shí)可用。
2.用戶操作程序
根據(jù)操作的鍵盤功能按鈕可以執(zhí)行以下用戶操作例程：通道重置。
頻道選擇。
查看報(bào)警級(jí)別。
催化傳感器電流檢查。
傳感器信號(hào)監(jiān)測。
接受更新警報(bào)查看時(shí)鐘/日歷。
啟動(dòng)維護(hù)記錄打印輸出。
通道復(fù)位和選擇由通道卡reset執(zhí)行/當(dāng)執(zhí)行其余功能時(shí)，選擇按鈕使用工程卡按鈕控件選擇通道控制卡。
在選擇時(shí)，一次只能選擇一個(gè)通道卡其微處理器監(jiān)控工程卡按鈕功能來確定應(yīng)該采取什么行動(dòng)。
連續(xù)按下RESET/SELECT（重置/選擇）按鈕約五秒鐘將執(zhí)行擴(kuò)展卡重置。
在此期間所選圖標(biāo)將閃爍開和關(guān)，當(dāng)閃爍停止時(shí)，重置將完成。
擴(kuò)展復(fù)位執(zhí)行以下功能：
a、 最大和最小讀數(shù)通過工程打印設(shè)備已清除。
b、 TWA警報(bào)
配置暴露警報(bào)時(shí)，激活的短期（STEL）或長期（LTEL）暴露警報(bào)被清除，暴露定時(shí)器復(fù)位。
注：只有具有活動(dòng)警報(bào)的通道才會(huì)受到擴(kuò)展重置。
可以重置其他通道上的曝光計(jì)算使用第3.3節(jié)中概述的程序。
Error Code Meaning
The lifetime is calculated on the difference between the sensitivity measured during 1st SPAN and that measured during subsequent normal SPANs, and is only updated during the SPAN function. This is a warning that the sensor output is becoming unacceptably low and may be due to age or due to the sensor being 'poisoned' by the presence of silicones, sulphur and lead compounds. The sensor should be replaced.
The signal under range message is displayed when the sensor signal reading is less than a predetermined level held within the channel configuration data. This predetermined level is below the normal operating range. This is typically due to the sensor signal drifting below the normal zero operating point. This could, depending on the sensor type, be due to large changes in climatic conditions, loose terminal connections, the sensor being poisoned or an early indication of the failure of the sensor. In some instances this error can be caused by short circuits in the sensor or cabling. The channel card should be calibrated and its operation checked The signal over range warning message is displayed when the sensor signal reading is more than a predetermined level held within the channel configuration data.This predetermined level is above the operating range.
OPERATING INSTRUCTIONS
These operating instructions refer to the facilities available for general operation and interrogation of the system without the Engineering Key fitted. Facilities that may effect the way the system operates are covered in the Engineer's Operating Instructions Chapter 7 which refers to facilities available when the Engineering Key is fitted. 2. USER OPERATING ROUTINES Depending upon which keypad function push-buttons are operated, the following user operating routines may be performed: Channel reset. Channel select. View alarm levels. Catalytic sensor current check. Sensor signal monitoring. Accept an update alarm View clock/calendar. Initiate a maintenance record printout. Channel reset and select are performed by the channel card RESET/ SELECT push-button while the remaining functions are performed, when a channel control card is selected using the Engineering Card pushbutton controls. Only one channel card can be selected at any one time and while selected its microprocessor monitors the Engineering Card push-button functions to determine what action should take place.Pressing the RESET/SELECT push-button continuously for approximately five seconds will perform an extended card reset. During this period the selected icon will flash on and off, and when the flashing stops the reset will be complete. The extended reset performs the following functions: a. Maximum and Minimum Readings The maximum and minimum gas readings available via the engineering printout facility are cleared. b. TWA Alarms When exposure alarms are configured, the active short term (STEL) or long term (LTEL) exposure alarms are cleared and the exposure timer is reset. Note: Only channels with active alarms are affected by the extended reset. The exposure calculations on other channels may be reset using the procedure outlined in Section 3.3.
