Reliance 0-57652-D模块
传感器信号监测信号按钮的操作允许监控所选通道传感器信号值。显示的参数为：
取决于安装到所选的传感器驱动模块的类型频道卡。
要进入传感器信号监控操作，请按以下步骤进行：
（1） 按住所需的通道卡复位/选择按钮约1.5秒，直到出现所选图标在频道显示器上。
（2） 按下信号按钮，选择通道卡显示器将指示传感器信号。
显示的值将取决于传感器的类型
安装在通道卡上的驱动模块如下：
a、 催化传感器驱动模块显示器将显示带电电桥电压在01和02之间测量，单位为mV。02是惠斯通下半部分的中心点通道卡上的桥。
b、 4-20mA传感器驱动模块
显示器将显示带电传感器回路电流在马
（3） 按下（）或（）按钮或等待30秒退出信号模式。
4.7查看时钟/日历时钟按钮的操作将导致当前时间以及要在所选频道卡上显示的日期。注意：此操作需要选择控制卡，但操作对所选控制卡没有影响，即仅用作显示设备。
要进入时钟/日历操作，请执行以下操作：
（1） 按住所需的通道卡复位/选择按钮约1.5秒，直到出现所选图标在频道显示器上。再次按下报警按钮，选择通道卡显示将指示A2级报警。
（4） 第三次按下报警按钮，选择通道卡显示将指示A3级报警。
（5） 第四次按下报警按钮，选择通道卡显示将指示STEL液位报警。
（6） 第五次按下报警按钮，选择所选频道板卡显示将指示LTEL级别警报。
（7） 进一步按下报警按钮将在再次设置报警级别。即A1、A2、A3、STEL和LTEL。
注：当报警功能被禁用时，报警阈值将在数字显示器中显示为“--”。
（8） 按下（）或（）按钮或等待30秒退出报警模式。
Sensor Signal Monitoring
The operation of the SIGNAL push-button allows the monitoring of the
selected channels sensor signal value. The displayed parameter is
dependent upon the type of sensor drive module fitted to the selected
channel card.
To enter the sensor signal monitoring operation, proceed as follows:
(1) Push and hold the required channel card RESET/SELECT pushbutton for approximately 1.5 seconds until the selected icon appears
on the channel display.
(2) Push the SIGNAL push-button and the selected
channel card display will indicate the sensor signal.
The displayed value will depend on the type of sensor
drive module fitted to the channel card as follows:
a. Catalytic Sensor Drive Module
The display will show the live bridge voltage
measured between 01 and 02 in mV. 02 is the
centre point of the second half of the Wheatstone
bridge which is on the channel card.
b. 4 - 20mA Sensor Drive Module
The display will show the live sensor loop current
in mA.
(3) Push the ( ) or ( ) push buttons or wait 30 seconds to exit the
SIGNAL mode.
4.7 View Clock/Calendar
The operation of the CLOCK push-button will cause the present time
and date to be displayed on a selected channel card.
Note: This operation requires a control card to be selected but the
operation has no effect on the selected control card, which is
used as a display device only.
To enter the clock/calendar operation, proceed as follows:
(1) Push and hold the required channel card RESET/SELECT pushbutton for approximately 1.5 seconds until the selected icon appears
on the channel display. Push the ALARMS push-button a second time and the selected
channel card display will indicate the A2 level alarm.
(4) Push the ALARMS push-button a third time and the selected
channel card display will indicate the A3 level alarm.
(5) Push the ALARMS push-button a fourth time and the selected
channel card display will indicate the STEL level alarm.
(6) Push the ALARMS push-button a fifth time and the selected channel
card display will indicate the LTEL level alarm.
(7) Further pushes of the ALARMS push-button will scroll through the
alarm level set points again. ie. A1, A2, A3, STEL and LTEL.
Note: Where an alarm function is disabled, the alarm threshold value
will be displayed as '- - - -' in the digital display.
(8) Push the ( ) or ( ) push-buttons or wait 30 seconds to exit the
ALARMS mode.
