【功能描述】

德国EPRO MMS6120 测量模块
产品描述
1. 信号输入
MMS6120有两路独立的电动式速度传感器信号输入— SENS 1H（z8）/SENS 1L（z10）和SENS 2H（d8）/SENS 2L（d10）。与之匹配的速度传感器为德国epro公司生产的PR926X 系列电动式传感器，输入电压范围为-5…+15 V dc 。
模块为每个传感器提供一个0…8mA的提升线圈电流，可补偿传感器线圈的机械沉降，此补偿电流在组态中可选：SENS 1+（z6）/SENS 1-（b6）和SENS 2+（d6）/SENS 2-（b8）。
传感器信号可以在模块前面板上SMB接口处测到。
此外模块还备有键相信号输入（必须大于13V），该信号是速度控制方式及频谱分析所必需的。
2. 信号输出
a. 特征值输出
模块有两路代表特征值的电流输出：I1+（z18）/ I1-（b18）和I2+（z20）/ I2-（b20），可设定为0…20mA或4…20mA。
模块有两路代表特征值的0…10 V电压输出EO 1（d14）/ EO 2（d16）。
b. 动态信号输出
模块提供两路0…20 Vpp动态信号输出AC1（z14）/ AC2（z16）用于频谱分析。
0…20 Vpp相当于特征值的量程。
3．限值监测
a. 报警值
每个通道可以分别设定报警值和危险值。报警开关特性为测量值上升时超限触发。为避免测量值在限值附近的变化反复触发报警，可设置报警滞后值，在满量程的1…10%之间选择，特性为下降触发。
b. 限值倍增器及倍增系数X
在特殊情况下，如过临界转速时，振动幅值会很大，乃至超限，但此时机组处于正常运行状态。为避免不必要的报警或跳机，可在软件中激活限值倍增器功能，并设置倍增系数X（1.00~5.00）提高报警值。使用此功能时，d18应为低电平。倍增系数X同时影响报警值和危险值。
c. 报警输出
模块给出四个报警输出：
通道1：危险D1-C，D1-E（d26，d28），报警A1-C，A1-E（b26，b28）
通道2：危险D2-C，D2-E（d30，d32），报警A2-C，A2-E（b30，b32）
d. 报警保持功能
使用此功能，报警状态将被保持。只有通过软件中复位命令（Reset latch channel 1/2）才能在报警条件消失后取消报警。

German EPRO MMS6120 measurement module

Product description

1. Signal input

The MMS6120 has two independent electric speed sensor inputs - SENS 1H (z8) /SENS 1L (z10) and SENS 2H (d8) /SENS 2L (d10). The matching speed sensor is the PR926X series electrodynamic sensor produced by epro, Germany, with an input voltage range of -5... +15 V dc.

The module provides each sensor with a 0... 8mA lifting coil current compensates for mechanical settlement of the sensor coil, which is available in configuration: SENS 1+ (z6) /SENS 1- (b6) and SENS 2+ (d6) /SENS 2- (b8).

Sensor signals can be detected at the SMB interface on the front panel of the module.

In addition, the module also has a key signal input (must be greater than 13V), which is necessary for speed control mode and spectrum analysis.

2. Signal output

a. Eigenvalue output

The module has two current outputs representing characteristic values: I1+ (z18)/I1- (b18) and I2+ (z20)/I2- (b20), which can be set to 0. 20mA or 4... 20mA.

The module has two 0's representing the eigenvalue... 10 V voltage output EO 1 (d14)/EO 2 (d16).

b. Dynamic signal output

Module provides two 0... 20 Vpp dynamic signal output AC1 (z14)/AC2 (z16) for spectrum analysis.

0... 20 Vpp corresponds to the range of eigenvalues.

3. Limit monitoring

a. Alarm value

Each channel can set alarm value and danger value separately. The alarm switch is triggered when the measured value rises beyond the limit. In order to avoid the change of the measured value near the limit value to trigger the alarm repeatedly, the alarm lag value can be set at 1... Select between 10%. The feature is drop trigger.

b. Limit multiplier and multiplication factor X

In special cases, such as when the critical speed is too high, the vibration amplitude will be large or even exceed the limit, but at this time the unit is in normal operation. In order to avoid unnecessary alarm or jump, the limit multiplier function can be activated in the software, and the doubling factor X (1.00~5.00) can be set to increase the alarm value. When using this feature, d18 should be low. The multiplication factor X affects both the alarm value and the danger value.

c. Alarm output

The module gives four alarm outputs:

Channel 1: Danger D1-C, D1-E (d26, d28), Alarm A1-C, A1-E (b26, b28)

Channel 2: Danger D2-C, D2-E (d30, d32), Alarm A2-C, A2-E (b30, b32)

d. Alarm hold function

With this function, the alarm status will be maintained. Only the Reset latch channel 1/2 command in the software can cancel the alarm after the alarm condition disappears.
