報(bào)警配置和繼電器測試
警報(bào)配置和繼電器測試操作循環(huán)經(jīng)過八個(gè)不同階段，A1、A2、A3、STEL、LTEL、TESTAI、A2.A3、TESTTEL和TESTLTEL。在前三個(gè)階段，報(bào)警LED和繼電器不受影響。前五個(gè)階段用于設(shè)置報(bào)警閾值，而后三個(gè)階段提供燈測試和繼電器測試功能。要選擇報(bào)警配置操作，請執(zhí)行以下操作：（1）將工程鑰匙插入工程卡前面板插座，并檢查解鎖LED（）是否亮起。（2） 按住所需的控制卡RESET/SELECT（重置/選擇）按鈕約1.5秒，并通過顯示選擇圖標(biāo)檢查所選控制卡是否指示其已被選中。（3） 按下工程卡報(bào)警按鈕，檢查所選控制卡信息顯示是否顯示A1表示報(bào)警閾值上升或A1表示報(bào)警閾下降。（4） 檢查所選控制卡數(shù)字顯示器是否指示A1報(bào)警閾值點(diǎn)。注：1.模擬顯示屏繼續(xù)顯示傳感器實(shí)時(shí)測量。2.如果報(bào)警被禁用，數(shù)字顯示屏上將顯示“---”，且無法進(jìn)行調(diào)整。（5） 如果需要，使用和按鈕設(shè)置新的A1報(bào)警閾值。注：閾值級別只能設(shè)置為控制卡配置中設(shè)置的高點(diǎn)和低點(diǎn)之間的級別。（6） 設(shè)置正確的液位后，如果不需要再進(jìn)行調(diào)整，則按下按鈕以設(shè)置新液位并永久保存。否則，轉(zhuǎn)至步驟（7）。注：如果需要在任何時(shí)候取消程序而不將原始設(shè)置更改為顯示值，請按下按鈕。（7） 再次按下工程卡警報(bào)按鈕，并重復(fù)步驟（4）至（6）設(shè)置A2閾值
按下工程卡警報(bào)
第三次按下按鈕，重復(fù)步驟（4）至（6）進(jìn)行A3閾值點(diǎn)設(shè)置。（9） 第四次按下工程卡警報(bào)按鈕，重復(fù)步驟（4）至（6）設(shè)置STEL閾值。（10） 第五次按下工程卡警報(bào)按鈕，重復(fù)步驟（4）至（6）設(shè)置LTEL閾值。（11） 第六次按下工程卡警報(bào)按鈕，測試將顯示在信息顯示屏上。最初，A1級別顯示在數(shù)字顯示屏上，A1 LED亮起。注：測試功能自動(dòng)禁用控制卡，以允許對報(bào)警LED進(jìn)行燈測試，并防止產(chǎn)生意外報(bào)警。為了測試?yán)^電器和FAULT LED（故障指示燈），必須使用INHIBIT（禁止）按鈕將控制卡設(shè)置為非禁止?fàn)顟B(tài)。（12） 使用和按鈕在包括A1、A2、A3和欠量程故障值在內(nèi)的一系列液位范圍內(nèi)升高或降低模擬氣體液位。檢查所選控制卡是否在模擬和數(shù)字顯示器上指示模擬氣體液位，以及LED上是否指示適當(dāng)?shù)膱?bào)警狀態(tài)。（13） 第七次按下工程卡報(bào)警按鈕，信息顯示屏上將顯示與STEL交替的TEST（測試），數(shù)字顯示屏上將顯示OFF（關(guān)閉）。（14） 如果啟用，使用和按鈕將STEL警報(bào)在OFF和ON之間切換。（15）第八次按下工程卡警報(bào)按鈕，信息顯示屏上將顯示TEST與LTEL交替，數(shù)字顯示屏上將顯示OFF。（16） 如果啟用，使用和按鈕將LTEL警報(bào)在OFF和ON之間切換。
ALARM CONFIGURATION AND RELAY TEST
The alarm configuration and relay test operation cycles through eight different stages, A1, A2, A3, STEL, LTEL, TESTAI, A2. A3, TESTSTEL and TESTLTEL. In the first three stages the alarm LEDs and relays are not effected. The first five stages are used to set the alarm threshold points while the last three stages provide a lamp test and relay test function. To select the alarm configuration operation, proceed as follows: (1) Plug the Engineering Key into the Engineering Card front panel socket and check that the Unlocked LED ( ) is illuminated. (2) Push and hold the required control card RESET/SELECT pushbutton for approximately 1.5 seconds and check that the selected control card indicates it has been selected by displaying the select icon. (3) Push the Engineering Card ALARMS push-button and check that the selected control card message display shows A1 for a rising alarm threshold or A1 for a falling alarm threshold. (4) Check that the selected control card digital display indicates the A1 alarm threshold point. Notes: 1. The analogue display continues to show the sensor live measurement. 2. If an alarm is disabled, '- - - -' will be shown on the digital display and no adjustment will be possible. (5) If required, use the and push-buttons to set a new A1 alarm threshold point. Note: The threshold level can only be set to a level that is between the high and low points set in the Control Card configuration. (6) When the correct level has been set, and if no more adjustments are required, push the push-button to set the new level and store this permanently. Otherwise proceed to Step (7). Note: If it is required to cancel the procedure at any time without altering the original setting to the displayed value, press the push button. (7) Push the Engineering Card ALARMS push-button a second time and repeat Steps (4) to (6) for the A2 threshold points setting
Push the Engineering Card ALARMS
push-button a third time and repeat Steps (4) to (6) for the A3 threshold points setting. (9) Push the Engineering Card ALARMS push-button a fourth time and repeat Steps (4) to (6) for the STEL threshold points setting. (10) Push the Engineering Card ALARMS push-button a fifth time and repeat Steps (4) to (6) for the LTEL threshold points setting. (11) Push the Engineering Card ALARMS push-button for a sixth time and TEST will be displayed on the message display. Initially the A1 level is displayed on digital display and the A1 LED is illuminated. Note: The TEST function automatically inhibits the control card to allow a lamp test of the alarm LEDs and prevent accidental alarms being generated. In order to test the relays and the FAULT LED, the INHIBIT push-button must be used to set the control card into the uninhibited state. (12) Use the and push-buttons to raise or lower the simulated gas level over a range of levels that includes the A1, A2, A3 and underrange fault values. Check that the selected control card indicates the simulated gas level on the analogue and digital display, and that the appropriate alarm states are indicated on the LEDs. (13) Push the Engineering Card ALARMS push-button for a seventh time and TEST alternating with STEL will be displayed on the message display and OFF will be displayed on digital display. (14) If enabled, use the and push-buttons to switch the STEL alarm between OFF and ON. (15) Push the Engineering Card ALARMS push-button for a eighth time, and TEST alternating with LTEL will be displayed on the message display and OFF will be displayed on digital display. (16) If enabled, use the and push-buttons to switch the LTEL alarm between OFF and ON.
