Bender MK-BN Manual

医疗场所隔离电源的外接报警和测试单元
使用目的
MK-BN报警显示和测试单元用于显示 isoMED427P
型绝缘监视仪上的故障信息。
标准
MK-BN外接报警显示和测试单元符合以下所列的医疗场所
的电气规范: IEC60364-7-710:2001, 中国国家标准GB16895和
GB50333-2002。
通用安全信息
除本技术数据说明书外，必须阅读随机的"本德尔产品的
重要安全指示"。
功能
显示
绝缘监视仪isoMED427P上的报警和操作信息由 报警和
测试单元MK-BN面板上的发光数码管 和发光二极管显示出来，
也可同时显示手术室无影灯电源的绝缘监视仪上的报警信息。
如果是手术室电源的绝缘监视仪报警，MK-BN面板上的电子
数码管将显示故障代码并闪烁，显示负荷测量值，即实时负
荷与额定负荷的百分比。
数码发光管显示以下内容：
-对地绝缘阻抗千欧值；
-实时的负载电流和允许的最大电流的百分比。
发光二极管显示：
-电源接通显示（绿色）
-绝缘故障（黄色）
-过电流（黄色）
-超温（黄色）
-MK-BN和isoMED427P系统故障
自检
按下"自检"按钮，可对MK-BN以及隔离电源系统内相关
的绝缘监视仪进行自检。参阅绝缘监视仪的使用说明。
按下"自检"按钮至少一秒。
所有的数码发光管均点亮，指示报警的发光二极管亦同时
点亮。松开"自检"按钮后，指示灯的自检结束。同时，连接
在系统里的isoMED427P绝缘监视仪接到总线的指令，进行自
检，几秒钟后，报警信息将通过isoMED427P显示屏和报警显
示单元的发光管显示出来，报警和显示单元内的蜂鸣器亦同时
响起，然后该显示单元返回到正常状态。自检报警信号只外接
显示在发送自检指令的那台报警和显示单元上。

Remote alarm indicator and test
combination for medical locations
Intended use
The MK-BN alarm indicator and test combination
is used to indicate operation and fault messages of an
insulation monitoring device isoMED427P
Standards
The MK-BN alarm indicator and test combination
complies with the following device standards and regula-
tions for erection of electrical equipment in medical loca-
tions: IEC60364-7-710:2001, GB16895, GB50333-2002.
General safety information
In addition to this data sheet, the documentation includes
the supplementary sheet "Important safety instructions for
BENDER products".
Function
Indications
The alarm and operating messages from insulation monitor-
ing devices isoMED427P are duplicated by the MK-BN
and indicated on the seven-segment display and by LEDs.
In addition, an alarm message from an additional insulation
monitoring device for operating theatre lamp circuits can
be indicated. In this case, the indication "OP" appears
alternately with the current load current measuring value on
the display "TRANSFORMER LOAD %" / "I%".
The seven-segment display indicates:
-The insulation resistance in k-Ohm
-The ratio of the instantaneous load current to the
maximum permissible secondary-load current in %.
LEDs indicate:
-Readiness for operation (green)
-Insulaton faults (yellow)
-Overcurrent (yellow)
-Overtemperature (yellow)
-System fault MK-BN and isoMED427P
Self test
By pressing the "TEST" button, a self test of the
MK-BN and the associated insulation monitoring
device can be carried out. For details refer to the documen-
tation of the insulation monitoring device.
Press the "TEST" button for at least 1 second.
All segments and decimal points on the display will be
activated, in addition all LEDs light up. After releasing the
"TEST" button, the lamp test is completed. At the same
time, the connected insulation monitoring device isoMED427P
is being requested via the BMS bus to carry out a self test.
After a few seconds, the alarm messages are indicated on
the displays and by the LEDs of the alarm indicator and
test combination. In addition the internal buzzer sounds.
Afterwards the alarm indicator and the test combination
returns to normal operation mode. The alarm messages of
the selftest are only indicated on that alarm indicator and
test combination where the test was intiated.
